Build apps with Reboot
A full-stack framework for the AI era. Reboot solves the hard problems once, at the framework level, so neither you nor your coding agent has to.
Trust the code your agent writes
Modern app development is quickly becoming AI-assisted, or entirely vibe-coded. Agents are blazingly fast junior engineers. They ship concurrency and retry bugs. They skip the things you didn't spell out: the reactive frontend, the sign-in flow, the retry that should have happened. They don't expect their code to crash. And they produce diffs you can't easily review. A harness is not enough. They need a rock-solid foundation to stand on.
Reboot is that foundation. Constraints make entire classes of bugs impossible. Durable state, reactive frontends, and signed-in users come built in rather than asked for. A crash loses nothing. And the semantics are simple enough, for humans and agents alike, that you can review what was written.
What Rust's borrow checker did for memory management, and React did for component-based frontends, Reboot does for your backend: backend safety and data encapsulation, enforced by the framework rather than by review.
What Reboot handles for you
- Correct concurrency and retry safety. Every method declares its
kind —
reader,writer,transaction, orworkflow— and Reboot enforces what each one may do. A read cannot sneak in a write, and a transaction is atomic across state types. - Durable applications. Not just a durable execution engine:
the moment a function returns, its
stateis saved. Workflows resume where they failed — the steps that already finished are memoized rather than run again — and transactions keep everything atomic. No database, no cache, no queue. - What agents won't build unless asked. You asked for a frontend, but what you really wanted was a reactive one. You wanted it to retry on an intermittent network failure, but instead it threw an error and never cleaned up its local React state. With Reboot you get these features, and many more, without ever having to ask.
- Signed-in users. Plug in your favorite auth provider — Google,
GitHub, Auth0, Ory — and Reboot runs the OAuth server in front of
it, so a person signing in
auto-constructs their
User: the per-user entry point the rest of your app hangs off. No session table, and no glue between the provider and your data. - Semantics you can actually review. Even if a harness could get an agent to handle all of the above, you would still have to read the diff. Reboot's semantics are simple enough, for humans and agents alike, that you can.
Python backends are supported today. TypeScript backends and React Native frontends are in alpha. More languages are coming.
Get started
The fastest path is to let an agent build it. Install the Reboot plugin for Claude Code or Codex:
curl -fsSL https://reboot.dev/install.sh | bash
Then describe what you want — "Build me a todo-list MCP UI with drag-and-drop to reorder", "Build me a scalable messaging app".
Let an agent build it, or build it by hand to see every file.
One app to serve every user — human or machine
You and your agents can build any kind of app with Reboot. One backend, one identity per person, and as many front doors as you need:
Humans reach your app through a browser, a phone, or a MCP client. Agents reach it over MCP. Other services reach it over HTTP.
