Mesa

Built for agents — ship today

Full Git semantics


Branch, merge, diff, blame—everything you expect, via API.

No rate limits


Make as many requests as you need. We scale with your agents.

Sub-50ms latency


P99 under 50ms. Your agent loops stay fast.

GitHub

Hit the rate limit — Retry in 3600 seconds

Rate limits block agents


5,000 requests/hour sounds like a lot until your agent hits it in minutes.

Their cloud, their rules


Your code lives on Microsoft's infrastructure. No BYOC, no data sovereignty.

Latency kills loops


200-500ms per request adds up fast in tight agent feedback loops.

Postgres & S3

Build it yourself — Good luck

No Git semantics


You lose branching, merging, and diff. Recreating version control is a project unto itself.

Custom everything


Indexing, search, conflict resolution—months of engineering before you ship anything.

Performance is your problem


Optimizing queries, caching, scaling—all on you to figure out.

const repo = await mesa.repos.create({ name: "my-app" });
// Commit files with full Git semantics
await repo.commit({
files: { "app.py": code },
message: "feat: add auth flow"
});
// Branch and merge
const branch = await repo.branches.create("experiment");
await branch.commit({ files, message: "try new approach" });
await repo.merge(branch);
// Time travel: restore any previous state
await repo.checkout({ commit: "abc123" });

Mount Mesa repos as a local filesystem. Your agents get familiar fs APIs while Mesa handles versioning, sync, and persistence behind the scenes.

  • POSIX-compatible interface
  • Automatic checkpointing
  • Works with any language/framework/sandbox
  • Zero config required
