What Is Bluesky, Who Uses It and How to Grow a Following

Bluesky is the social app most people name when they leave X, and almost everything written about it is either a launch story from 2024 or a growth blog with nothing behind it. Here is what it actually is, who is on it now, what its own transparency report and four peer-reviewed studies measured, and which growth tactics survive contact with that evidence.

Bluesky works like Twitter and not like Reddit, so you post to a timeline and not to a channel

This is the first thing people get wrong, and it decides how you use the app.

• You post to your own followers on Bluesky, not into a topic channel, exactly like Twitter and unlike a subreddit. There is no equivalent of r/photography to submit to.
• Bluesky has posts, replies, reposts, quote posts, likes and a 300 character limit, so anyone who has used Twitter already knows the whole interface.
• Your home screen is a set of tabs you choose, with Following and Discover as the two defaults. Following is strictly chronological, and Discover is the recommendation feed.
• Anyone can build a feed and publish it for other people to pin as a tab, which is the one genuinely different idea in the product and the section below explains why it matters far less than it sounds.
• Bluesky added group chats in June 2026 and has confirmed Reddit-style Communities for later in 2026, so the answer to this heading changes at the end of this article.

Ignore Bluesky's claim that you own your network, because a ban still takes your whole audience

Owning your network is Bluesky's biggest selling point and its emptiest one. Here is exactly what it is worth on the day they throw you off, which is close to nothing.

• A ban costs you your audience on Bluesky exactly as it would on X. The people who follow you stay in the Bluesky app and will never see another post from you.
• All you keep is a copy of your own posts and a list of the account names that followed you.
• A list of account names is not a way to contact anybody, because Bluesky never gives you an email address or a phone number for a follower.
• "You own your network" means the company cannot lock your writing inside its app, and nothing more. It is a promise about files, not about people.

Bluesky has about 46 million registered accounts and 10.4 million monthly active users

Registered accounts and active users are two completely different numbers, and almost every Bluesky statistics page quotes the flattering one.

• Bluesky had nearly 46 million registered accounts as of August 2026, up from 25.94 million at the start of 2025 and 41.41 million at the end of it, which the company published itself.
• Only about 10.4 million of those accounts used the mobile app in June 2026, so roughly four in five registered accounts are dormant.
• Daily active users on mobile sat at about 3 million in July 2026. That is the number of people who could see your post on any given day.
• Bluesky users wrote 1.41 billion posts in 2025, which was 61% of every post ever made on the platform. The people who are active are very active.
• About 29% of Bluesky's monthly users open it on a given day, which is a respectable rate for a social app and says the remaining audience is a real habit rather than a trickle.

Bluesky's active users have more than halved since late 2024

This is the answer to whether Bluesky is growing, and it is not the answer the platform's own signup counter gives.

• Bluesky averaged about 22.1 million monthly active users in the last quarter of 2024 and about 10.7 million in the second quarter of 2026, a fall of roughly 52%.
• Monthly active users were down 27.2% year on year in June 2026 and daily active users down 25.6% in July. The decline is current, not a one-off correction.
• Registered accounts keep rising while active users fall, because signups from 2024 never came back. Both numbers are true and only one of them is an audience.
• The two spikes that built Bluesky were Brazil banning X in September 2024 and the November 2024 US election, which took it from about 13 million accounts at the end of October to over 22.5 million by late November.
• A platform of 3 million daily users is still larger than every independent forum and far smaller than Reddit, so treat it as a real but modest audience rather than a Twitter replacement.
• Bluesky's new chief executive is now promoting the protocol rather than the app, so the app you are growing on is not the company's first priority.

Use Camera to Clipboard to put a phone photo into a Bluesky post you write on a computer

Bluesky posts are capped at 300 characters, so a picture does most of the work, and most people write their longer posts on a computer while the picture is on their phone. Camera to Clipboard, one of my own apps, moves it across without a cable or an email to yourself.

• A photo you take inside Camera to Clipboard is on your computer's clipboard the moment you take it, ready to paste into the Bluesky post box. The phone and the computer find each other over your own local network.
• Screenshots already in your phone's library can be sent one at a time or several at once, which suits Bluesky because a post takes up to four images.
• The image arrives as an ordinary clipboard image, so it pastes straight in rather than needing an upload dialog.

Three quarters of Bluesky users are left of centre, but only 13% of posts are political

Both halves of that sentence are measured, and people who quote Bluesky statistics usually quote only one of them.

• A study of 4.75 million Bluesky accounts published in PLOS One found 75.3% of users left of centre and 4.81% right of centre, with the remaining 19.79% classed as centre.
• Only 0.14% of the links shared on Bluesky came from sources rated questionable, spread across 3,704 accounts, so the misinformation problem is genuinely small.
• A separate study of 43.6 million posts found 82% of accounts discussing the Trump administration opposed it and 1% supported it. On every issue measured, the minority view was 1% or less.
• 87.3% of all Bluesky posts are not political at all, so the politics is loud rather than constant.
• The most searched Bluesky terms in the United States are the names of political journalists and lawyers, which tells you who the platform is known for even though most posting is about something else.

Bluesky is mostly American, young and male, with 62.7% of users under 35

The country figures come from web analytics vendors rather than from Bluesky, and they disagree with each other, so treat them as a shape rather than a measurement.

• 35.02% of Bluesky users are aged 18 to 24 and another 27.67% are 25 to 34, putting 62.69% of the platform under 35.
• Bluesky is 62.04% male and 37.96% female by Similarweb's panel, which matches the usual pattern for a technology-led platform.
• The United States supplies the largest share of Bluesky traffic, somewhere between 25.6% and 48.87% depending on whose measurement you take. The two vendors disagree by more than 20 percentage points, so nobody knows precisely.
• Brazil, Japan, the United Kingdom, Germany and Canada make up most of the rest, and Brazil is there because its government banned X for three weeks in 2024.
• Japan is unusually large for an English-language platform at roughly 8.7% of traffic, driven by artists and illustrators rather than by news.

Art, science, journalism and furry fandom are the communities that actually work on Bluesky

Bluesky has no channels, so a community here is a cluster of accounts who follow each other, usually seeded by a starter pack.

• Artists and illustrators were the first large non-political group to move to Bluesky, and the furry art community is one of the biggest, with over 110 starter packs listing its members.
• Scientists, academics and science communicators left X in large numbers and rebuilt on Bluesky, with astronomy and climate research among the most active clusters.
• Political journalists, lawyers and news commentators are the group Bluesky is best known for, which is why searches for their handles dominate the platform's search demand.
• Sports writing works, particularly American football, where a cluster of beat reporters and fantasy analysts moved together.
• Business, marketing and consumer brands are the weakest fit, because the audience is small and openly hostile to advertising. Being useful in your subject works, and campaigns do not.

Get into a starter pack, because starter packs drove up to 43% of all follows on Bluesky

This is the one growth tactic with a peer-reviewed study behind it, and it is not the one the growth blogs lead with.

• A starter pack is a shareable list of up to 150 accounts that a reader can follow with one click, and Bluesky shows packs to people during signup.
• Researchers studying 25 million Bluesky users found starter packs drove up to 43% of all new follows at peak and about 20% across the whole period, from June 2024 to January 2025.
• Accounts included in a starter pack gained up to 85% more followers and posted 60% more than comparable accounts left out of one.
• People who created a starter pack gained up to 117% more followers themselves within four weeks of publishing it. Making one is as effective as being in one.
• Only 6.25% of Bluesky users were in any starter pack at the time of the study, so the tactic is nowhere near saturated.
• The same researchers warn that starter packs reinforce existing communities rather than create new ones, so a pack works when you are already known to a few people in your subject.

Follow accounts in your subject, because 39% of Bluesky follows are returned

Following somebody back is normal on Bluesky and it is not normal on X, which makes the cheapest tactic here also the most reliable one.

• When you follow somebody on Bluesky they get a notification with your name on it, and many of them tap it to look at your profile. That is the whole mechanism, it costs you one tap, and it costs them nothing.
• 39% of the 14.5 million follow connections measured across 4.1 million Bluesky accounts were mutual, so following someone wins you a follower about two times in five.
• A Bluesky follower really does see your posts, because the main feed lists everyone you follow in time order with no algorithm deciding who gets through. That is not true on Instagram or on Facebook, where a follower may never see you again.
• Following 30 relevant accounts a day is the whole tactic, and it needs no content at all.
• Take the accounts from a starter pack in your subject or from a rival's follower list, because both are already filtered down to people who care about that one thing.
• Never use a follow-then-unfollow tool, because Bluesky shows everyone's follow list in public and people can see you did it.

Download a rival's follower list and follow everyone on it, because Bluesky's data is free

This is the single cheapest way to build an audience on Bluesky, and it exists only because the platform lets anybody read it without paying.

• Tapping the follower count on any Bluesky profile shows you every single account that follows them, and you can scroll the lot. No tool, no account and no permission, and pulling the same list in bulk is one free web request.
• A rival's follower list is the best targeting list you will ever get, because every name on it has already chosen to hear about your subject.
• Work through that list at 30 follows a day and roughly two in five of them will follow you back, which is the 39% mutual rate measured across 4.1 million Bluesky accounts.
• Do the same with the members of any starter pack in your subject, which is a shorter list and a better filtered one.
• Pulling the same list off X costs $0.010 for every single name on it, so a rival with 100,000 followers would cost you $1,000. X removed its free tier entirely in early 2026, so there is no way to do it for nothing there.

Reply inside other people's threads, because 57% of Bluesky replies get a reply back

Replying is the most repeated Bluesky growth advice, the reason usually given for it is wrong, and the tactic still works.

• Growth blogs claim a Bluesky reply is broadcast to the followers of the account you replied to, and that stopped being true in version 1.90. The Following feed now shows a reply only when at least two accounts you already follow are in the conversation.
• 57% of reply connections on Bluesky are mutual, measured across 23.4 million of them, so replying to someone usually gets a reply back.
• Replying works because the thread itself is read, and because a reply is a link to your profile in front of people already interested in that subject.
• Bluesky's Discover feed weights replies more heavily than likes, so a post that starts a conversation travels further than one that collects hearts.
• Bluesky's own reply filtering cut reported anti-social behaviour by 79%, so replying to strangers is a lower risk here than on X.
• Post owners can hide replies and can restrict replies to their own followers, so a reply-heavy strategy will sometimes hit a closed door.

Get reposted, because a repost is the only thing that reaches a whole new follower list

A reply reaches the thread. A repost reaches everyone who follows the person who reposted you, and it is the only mechanism on Bluesky that does.

• 27% of all Bluesky posts are reposts and another 5% are quote posts, measured across 235.5 million posts, so resharing is roughly a third of everything on the platform.
• Only 8% of repost connections are mutual, against 57% for replies, so reposts travel one way from a small number of well-followed accounts outward.
• Some Bluesky accounts have been reposted by more than 50,000 separate people from a single post.
• Write the post so that resharing it costs the resharer nothing, which means one complete idea that needs no reply to make sense.
• Reposting other people is how you become worth reposting, because the 8% figure means the favour is rarely returned by accident.

Put the words your subject's feeds filter on inside the post itself

Most Bluesky feeds are keyword filters rather than recommendation engines, which means you can put yourself into one on purpose.

• A custom Bluesky feed is usually a keyword or pattern filter, so a post containing that keyword enters the feed no matter how few followers you have.
• Bluesky made hashtags clickable and searchable in February 2024, so a hashtag is a real search term here rather than decoration.
• Find the busy feeds in your subject first, read what they are filtering on, then use those exact words. An art feed pulling on the word art will never find a post that only says painting.
• Two hashtags is the practical limit inside a 300 character post, so pick the one broad word and the one narrow word.
• Use the same handful of words in every post so the Discover feed can work out what you are about, since it blends what your network engages with rather than reading your profile.

Do not build a custom feed, because only 2.8% of Bluesky users have ever used one

Custom feeds are the headline feature of Bluesky and the single most repeated piece of growth advice about it.

• The PLOS One study found 39,639 custom feeds created by 18,352 accounts, and only 139,033 users had ever liked one. That is about 2.8% of the users in the study.
• The average custom feed collected two likes. Building one is a weekend of work for an audience of nobody.
• Growth blogs claim that over 60% of Bluesky discovery now happens through custom feeds, and not one of them names a dataset. The only published measurement says the opposite.
• Pinning somebody else's popular feed is still worth doing, because it is where you find the accounts in your subject to reply to. Reading feeds and publishing feeds are different activities with different payoffs.
• Bluesky launched a tool called Attie in March 2026 that builds a feed from a written prompt, which lowers the effort but does nothing about the audience.

Use Repeat Recorder to rehearse a short video before you post it to Bluesky

Bluesky takes video, and a video post is the one format that reaches past your own followers into the Discover feed. The hard part is that the words have to be said out loud instead of edited quietly. Repeat Recorder, another of my own apps, records you and plays the take straight back without you touching the phone.

• Repeat Recorder plays each take back automatically and then starts recording again, so you can run the same line twenty times without picking the phone up.
• Repeat Recorder was built for speech rehearsal, language learning and vocal training, and it has adjustable reverb effects as well.
• Takes worth keeping go into favourites and into folders you name yourself, dragged into whatever order you want.

Post on Saturday, because Saturday posts get 79% more engagement than Thursday posts

Bluesky's timing pattern is the opposite of the office-hours advice every scheduling tool gives, and it is the opposite of most other platforms.

• Buffer measured over 3 million Bluesky posts and found Saturday averaged 6.17% engagement and Sunday 6.05%, against Thursday's 3.44%.
• The three strongest single hours were Saturday at 5pm on 6.89%, Saturday at 6pm on 6.81% and Sunday at 9am on 6.77%.
• Weekday late morning to early afternoon, roughly 10am to 1pm, was the quietest window of the week, which is exactly the slot most scheduling tools recommend.
• Timing matters more on Bluesky than on an algorithmic platform, because the Following feed is strictly chronological and a post has one to two hours before it is gone.
• All of these times are in your own audience's local time zone, not yours. Our posting heat map converts a week of hours into whichever zone you are working with.

Just post, because the median active Bluesky account has written only 8 posts

The bar for being one of the more active accounts on Bluesky is far lower than on any other platform, and this is the finding that should decide whether you bother.

• Across 4.1 million Bluesky accounts, only 58% had ever posted once, and the median among those who did was 8 posts in total.
• Half of Bluesky accounts were active on more than 50 separate days and only 22% on more than 150 days, so most people visit without ever writing anything.
• Writing one post a day for a month puts you above the median active account roughly four times over.
• Every claim you will read about the right Bluesky posting rate comes from a growth tool blog with no dataset named, so treat 3 to 5 posts a day as marketing rather than a finding.
• Consistency beats volume here, because the Discover feed rewards a post that gathers replies quickly and you cannot be there for a reply if you posted five times and left.

Post your links on Bluesky, because it is the one platform that does not demote them

If you have a website, an app or a newsletter, this is the strongest single reason to be here at all.

• Bluesky's chief operating officer has stated plainly that the platform does not demote posts containing links, which X and LinkedIn both do.
• The news site EUobserver got 3,800 unique visitors in one week from 3,300 Bluesky followers, and 1,320 visitors from 203,000 followers on X. Sixty times fewer followers produced almost three times the traffic.
• The Boston Globe reported three times more traffic from Bluesky than from Threads and 4.5 times more paid subscription conversions.
• These are individual publishers reporting their own numbers rather than a controlled study, so treat the size of the gap as uncertain and the direction as reliable.
• A small Bluesky following is worth far more per follower than a large X following if your goal is clicks, which inverts how you should judge the platform's size.

You can stay pseudonymous on Bluesky, unless you are in the UK or three US states

Bluesky is one of the more pseudonym-friendly platforms in social media, with one growing exception.

• Bluesky never asks for your legal name, and an email address plus a chosen handle is the whole signup. No phone number and no identity document in most of the world.
• A brand can run an account with no person named anywhere on it, which puts Bluesky in the same tier as Reddit and ahead of Threads and LinkedIn.
• The UK now requires age assurance under the Online Safety Act, checked by a face scan, an ID scan or a credit card through a third party called Kids Web Services. Refusing it keeps your account but removes direct messages and adult content.
• South Dakota and Wyoming have passed similar laws, and Bluesky runs the same age check for users there.
• Bluesky blocked Mississippi entirely on 22 August 2025 rather than comply with a law carrying a $10,000 per user penalty, and reopened it to verified adults on 8 December 2025.
• Pointing your own domain at your handle proves you control that domain, so it is verification and exposure at the same time, and a domain registration needs WHOIS privacy if you want to stay unnamed.

Reddit-style Communities arrive on Bluesky in 2026 and will change how you grow there

Bluesky's product team has confirmed the feature, and it is the largest change to the platform since starter packs.

• Bluesky Communities will be topic spaces you post directly into, each with its own handle, URL and feed, which the company's own head of product says will feel familiar to Reddit users.
• Bluesky launched group chats in June 2026 as the first step, and Communities are confirmed for later in 2026 with no date announced.
• Communities give Bluesky the one thing it currently lacks, which is a place to post where strangers are already reading.
• Meta's Threads shipped its own communities feature in late 2025, so this is the direction every Twitter-shaped app is moving.
• Claim a community in your subject early if you want to own one, because the pattern from starter packs is that the first movers keep the advantage.

Every Bluesky growth tactic ranked by the evidence behind it

Eight of these rest on a named dataset that anyone can check, three on a company statement or a publisher reporting its own figures, and two on nothing but a growth blog.

Give Bluesky 15 minutes a day if you have a website to send people to, and skip it otherwise

Bluesky is shrinking and it is not dying, and those are different things. Here is the verdict the numbers in this article actually support.

• Bluesky's decline is slowing sharply, from 7.8 million monthly users lost in the six months after the peak to 3.9 million lost across the following twelve. That is my own arithmetic on the published figures, not a reported number.
• The 3 million people who open Bluesky every day are a real audience, roughly 60 times the whole of Lemmy and larger than any independent forum.
• 29% of Bluesky's monthly users open it on a given day, and they wrote 61% of every post ever made on the platform during 2025 alone. The tourists left and the residents stayed.
• Bluesky is worth your time if you have a website, an app or a newsletter to send people to, because it is the only large platform that does not bury your links. One news site got 3,800 visitors from 3,300 followers in a week.
• Skip Bluesky if you sell to a general consumer audience or you need scale, because it is small, it leans hard left and it dislikes advertising.
• Never make Bluesky your main channel, because a platform losing a quarter of its users a year cannot carry a business. Fifteen minutes a day is the right budget for it.

Conclusion: what Bluesky is and how to grow on it, in one glance

Bluesky is a Twitter-shaped app with a shrinking audience and one property no rival has, which is that it does not bury your links.

• Bluesky has about 46 million registered accounts and only 10.4 million monthly active users.
• Bluesky's active users have more than halved since late 2024 and are still falling about 27% a year.
• Three quarters of Bluesky users are left of centre, though 87.3% of posts are not political.
• Bluesky is shrinking and not dying, because the rate of loss has roughly halved since the peak.
• Give Bluesky 15 minutes a day if you have a website to send people to, and skip it if you do not.
• Bluesky's claim that you own your network is worth almost nothing, because a ban still takes your audience.
• Get into a starter pack first, because starter packs drove up to 43% of all follows.
• Follow accounts in your subject, because 39% of Bluesky follows are returned.
• Download a rival's follower list and follow everyone on it, because Bluesky's data is free to read.
• Reply to people, because 57% of Bluesky replies get a reply back.
• Post on Saturday, because Saturday posts get 79% more engagement than Thursday posts.
• Post at all, because the median active Bluesky account has written only 8 posts.
• Post your links here, because Bluesky is the one platform that does not demote them.
• Do not build your own custom feed, because the average one collected two likes.
• You can stay pseudonymous everywhere except the UK, South Dakota, Wyoming and Mississippi.
