Production that
fixes itself.
Production should never go down. Rebar finds what broke, proves the fix, and ships it before your users notice. The goal is the end of on-call.

Plugs into everything you already run
Every minute of downtime costs you users and burns out the engineers paged to fix it. A machine can catch and fix most of it faster than a human can wake up. Rebar is the reinforcement under your stack.

Every system you run, watched on a loop.

Proven in a sandbox before it ships.

Rolled back the moment it slips.
Where Rebar fits
The worst bugs pass review.
Code review reads your diff and flags what looks wrong. But a clean diff still ships outages: a bad config, a regression no diff can show, a dependency that breaks at runtime. Rebar owns that half. It watches production and fixes what review never sees.
Before it merges
- Reads the pull request
- Flags what might be wrong
- A person applies the fix
- Then it merges. Whatever it missed goes live.
After it deploys
- Watches live production
- Finds the deploy that broke it
- Proves the fix, then ships it
- Rolls it back if it slips
Run both. One guards the door. The other watches the room.
Know what broke, and why
Rebar reads your deploys and runtime on a tight loop. When something slips it names the cause in plain language, and tells you whether a dependency broke, your code regressed, or the change was intended.

Rebar doesn't merge on a hunch. It checks each fix against an independent source of truth, like a dependency's own types, then proves the fix builds and boots in a sandbox before a single line reaches production.

Stay in command
Run in Review and approve every fix, or let Rebar handle the safe ones and ask you about the rest. Reversible fixes can ship on their own; risky ones always wait. One switch stops every system at once.

What ships on its own
Everything else, handled
Pull requests, not magic
Every fix lands as a normal pull request you can read, review, and revert.
Auto-revert
If a merged fix regresses in production, Rebar rolls it back on its own.
Learns your systems
Rebar remembers how similar breakage was handled before, and reuses what worked.
Dependency updates
Rebar proposes and verifies dependency bumps before they break you.
Full activity log
A plain record of everything Rebar did, when, and under whose authority.
Built for agents
Drive Rebar from your own tools over a CLI, MCP server, and public API.
Stop babysitting production.
Connect your systems and Rebar takes it from there. You approve what you want today, and it earns more every week. The destination is production that runs itself.
