What Is Bluesky? Everything You Need to Know
On this page
Bluesky is the social app many people moved to when they wanted something that feels like early Twitter: short posts, real-time news and conversation, without a single company deciding everything you see. This guide explains what Bluesky is, how it works, whether it’s free, and how to get started in a few minutes.
Bluesky in one paragraph
Bluesky is a microblogging social network: you write short posts (up to 300 characters), add photos or videos, follow people and reply to each other. It looks and feels a lot like X (Twitter). The difference is underneath: Bluesky is built on an open network called the AT Protocol, so you choose your feeds, your moderation, and even your username’s domain. By early 2026 Bluesky had passed 40 million registered users.
Where Bluesky came from
Bluesky started in 2019 as a research project funded by Twitter, with the goal of building an open standard for social media. It became an independent company in 2021, opened to the public without invitations in February 2024, and grew fast whenever people left X in large numbers. It’s run as a public benefit company and is funded by investors rather than by selling your data to advertisers.
How Bluesky works
Posts and threads
- Posts can be up to 300 characters.
- Add up to 4 images, or one video.
- Videos can be up to 10 minutes long (raised from 3 minutes in August 2026).
- Reply, repost, quote-post and like, just like on X.
- Long thoughts become threads: tap + in the composer to add another post.
Feeds: you choose the algorithm
On X, one algorithm decides your timeline. On Bluesky:
- Following shows posts from people you follow, newest first.
- Discover is Bluesky’s own recommendation feed.
- Custom feeds are built by anyone: science news, cat photos, art, posts from your city. Search for feeds and pin the ones you like as tabs.
Starter packs
A starter pack is a list of accounts (and feeds) put together by another user around a topic, like “UK journalists” or “indie game devs”. Tap Follow all and your timeline fills up in seconds. Starter packs are the fastest way to make Bluesky feel lively.
Handles and custom domains
Every account has a handle like name.bsky.social. If you own a website, you can make your domain your handle (for example @tapdl.com). It’s a simple form of verification: only the owner of the domain can use it.
Verification
Bluesky also shows blue checks on notable accounts, and lets approved organizations (newsrooms, for example) act as Trusted Verifiers for their own staff. You can’t buy a check on Bluesky.
Moderation you control
Bluesky has its own moderation team, and you can add more on top:
- Mute words and hide replies you don’t want to see.
- Block and mute accounts, or subscribe to shared block lists.
- Subscribe to labelers, independent services that tag content (for example spoilers or AI images) so you can hide or blur it.
Is Bluesky free?
Yes. Bluesky is free to join and use, with no ads in the main feed today. The company has said it plans optional paid extras (a subscription called Bluesky+), but the core app stays free.
How to join Bluesky
- Download the Bluesky app for iPhone or Android, or open bsky.app in a browser.
- Tap Create account.
- Enter your email, a password and your date of birth.
- Choose your handle (you can change it later).
- Pick a few interests so Bluesky can suggest accounts and feeds.
- Follow a starter pack or two to fill your timeline.
How to use Bluesky well in your first week
- Fill in your profile: photo, banner and a one-line bio so people know who you are.
- Follow 50+ accounts in your interests, using starter packs and search.
- Pin 2–3 custom feeds for your topics.
- Reply more than you post: conversations are how people find you on Bluesky.
- Use alt text on images; the community appreciates it.

Bluesky for creators and businesses
- Use your domain as your handle so people know it’s really you.
- Make a starter pack of your team, your guests or your niche; it’s a great way to get followed.
- Post natively: links work, but native images and videos get more engagement.
- Pin your best post to your profile so new visitors see it first.
- Join conversations: Bluesky rewards replies and quote posts more than broadcast-style posting.
- Track what works: Bluesky has no built-in analytics yet, so watch likes, reposts and follows per post.
Bluesky videos
Bluesky video works like X or Threads: record or choose a video, add captions or alt text, and post. Videos play in the feed automatically without sound. There’s no built-in download button, because Bluesky streams videos in small pieces rather than as one file. To keep one, copy the post link (Share → Copy link to post) and paste it into the Bluesky video downloader, which joins the pieces into a single MP4 with sound. Photos in the post download at full size too.

Is Bluesky safe?
Bluesky is as safe as any public social network: posts, likes and follows are public by default and visible to anyone, even without an account. Direct messages are private.
