- Bluesky is a decentralised, Twitter-style social network built on the open AT Protocol. Founded by Jack Dorsey, opened publicly in February 2024.
- By 2026, Bluesky has ~30M users — small vs Twitter/X, but the fastest-growing alt social network of the decade.
- Key differences from X: algorithmic transparency, custom feeds, custom moderation, no ads, account portability via decentralised handles.
What Is Bluesky?
Bluesky is a microblogging social network that looks like Twitter but is built on different principles:
- Decentralized — runs on the open AT Protocol, meaning anyone can host their own server and interoperate.
- Algorithmic choice — pick from thousands of community-made feeds, not just one centralized algorithm.
- Custom moderation — subscribe to community-curated moderation lists; Bluesky doesn't have a single moderation truth.
- Account portability — your handle can move to another AT Protocol server without losing followers or posts.
- Open API — full access for bots, third-party apps, integrations.
- No ads (as of 2026).
How Bluesky Started
Bluesky was announced in 2019 as a Twitter-funded research project for decentralised social media. Jack Dorsey kept funding it after leaving Twitter. It launched in February 2023 as invite-only and went fully public in February 2024.
Major growth waves:
- Late 2023 — first wave of Twitter exiles.
- Nov 2024 — post-US-election surge (~10M new users in 2 weeks).
- 2025-2026 — sustained growth via custom feeds and creator migration.

How Bluesky Handles Work
By default, your handle is yourname.bsky.social. But Bluesky lets you verify a custom domain as your handle:
- Own a domain like
yourname.com. - Add a DNS record verifying ownership.
- Your Bluesky handle becomes
@yourname.com.
This doubles as identity verification — anyone visiting bsky.app/profile/yourname.com knows that handle is tied to your domain.
What Are Bluesky Feeds?
Unlike Twitter/X (one algorithmic feed), Bluesky has thousands of community-made feeds:
- Discover — Bluesky's default For You-style algorithm.
- What's Hot — trending posts.
- Custom feeds — Tech, Science, Art, Photography, Coding, Politics — subscribe to any.
- Make your own feed — anyone can build a feed via the AT Protocol.
You decide which feeds appear on your home page. This is Bluesky's core innovation — algorithmic choice.

Frequently Asked Questions
Is Bluesky owned by Twitter?
No. Bluesky was funded by Twitter from 2019-2022 but is now an independent public benefit company. Twitter (now X) has no control or ownership.
Is Bluesky free?
Yes — completely free. No ads, no Premium tier as of 2026. Bluesky is funded by Series A investment + future plans for paid features (not ads).
Can I delete my Bluesky account?
Yes — Settings → Account → Delete account. Your handle is freed for reuse after deletion.
Is Bluesky decentralized in practice?
Partially. The AT Protocol is open and decentralized in design, but most users still run on Bluesky's own servers. True multi-server use is technically possible but rare.
Will Bluesky replace Twitter?
Unlikely — X has 20x more users. But Bluesky has captured a meaningful slice of "exit" users and continues growing. Both will likely coexist for years.
