The social web is a set of walled gardens.
Your identity, your audience, and everything you have ever posted live inside databases you don’t control. You can’t take your followers with you. You can’t leave without starting over. And no one can build anything new without a platform’s permission — until that permission is revoked.
When a platform changes its rules or shuts down, everything you built on it goes with it.
An open web you actually own.
AT Protocol — the open network behind Bluesky — flips the model. Your identity and your data live in a repository you control and can move at will. Any application can build on the same open network, so your audience and your content are never trapped in a single app. Portability and interoperability, by default.
- × One company owns the database
- × Leaving means starting over
- × Build only with permission
- → You hold your own data repository
- → Move apps, keep your graph
- → Anyone can build, no gatekeeper
AT Protocol already works — and people are building on it every day. Our job is to make it more useful: we run the infrastructure it depends on, bring real-world data onto the network, and build apps that show what it can do.
Three ways we build the open web.
Infrastructure the network runs on, real-world data anyone can build with, and apps that prove it all works — every layer of the open web on AT Protocol.
The plumbing of the open web.
Global relays, real-time Jetstreams, mirrors, and developer tools that AT Protocol apps rely on — much of it free and open, with hosting and higher limits when you scale.
Relays carry the full firehose with a 72-hour replay window; Jetstreams stream a lightweight JSON version. Hover any row to watch its live events.
Real-world data, open for anyone to build on.
We publish public information — menus, places, events, organizations, and directories — onto AT Protocol as open, structured records, so anyone can build search, maps, and apps on top of it.
Once that data exists openly, anyone can build search engines, maps, recommendations, assistants, local apps and accessibility tools on top of it — no gatekeepers, no closed database to negotiate access to.
Products built on the open web.
Real apps and services running on the same foundation — from developer tools to everyday apps — useful today, and proof the open network works.
Everything we already run.
The infrastructure behind it all — relays, developer tools, services and mirrors, live today and open for anyone to use.
What we’re building next.
New infrastructure, verification, and more apps for the open web — being built now.
