Review behavior, not just the diff. Nothing merges on trust.
Stratum is git hosting built for teams shipping agent-written code. It works with any agent, and every change proves itself — tests, evaluations, human approval, provenance — before it merges. Start as a layer over GitHub, or make Stratum the source of truth. Join the hosted beta or self-host it.
We'll notify you when early access opens. No spam.
You're on the list.
Three things every closed forge makes you give up. Stratum gives you all of them.
Join the hosted beta, or self-host the whole platform on your own Cloudflare account. It's open source either way — your code stays portable, with no proprietary SaaS lock-in.
Works with whatever agents and editors your team already uses. Stratum isn't tied to a single vendor's IDE or coding agent.
Nothing merges on trust. Every change proves itself with tests, evaluations, and provenance — governance built into the forge, not bolted on.
GitHub's review workflow assumes a human typing a small, readable diff at the keyboard. Agents break that assumption: they work across many tasks at once and produce more changes than a team can read line by line.
What matters then isn't the diff — it's whether the change behaved correctly, who or what made it, and whether it followed your rules. Stratum is built for that handoff: agents do the work, and teams keep clear evidence and control before anything ships.
Stratum helps teams decide whether a change behaved correctly before it merges.
A closed forge built for the agentic era can match our speed, our agents, our merge gates. It can't match open. Stratum is open source, top to bottom — join the hosted beta or self-host the whole platform on your own Cloudflare account. Your code stays yours, and it stays portable.
Every commit in Stratum can carry the record behind it: which agent wrote it, which model was used, a hash of the agent's prompt, and the evaluation evidence that gated the merge — captured at merge, and queryable per change.
As agents write more code, accountability matters more, not less. Stratum keeps provenance close to the code so teams can understand the path from request to shipped change.
Stratum is open source — no closed forge, no vendor lock-in. Each project is its own git repository with its own merge queue. The fastest way to start is the hosted beta at app.usestratum.dev; Stratum Cloud, a managed tier with billing and SSO, is planned. Prefer to keep everything in-house? Self-host the whole platform on your own Cloudflare account and pay only for what you use.
github.com/stratum-eng/stratum →Stratum is an open-source git forge built for teams whose code is written by AI agents as well as humans. It hosts your repositories, gives every agent task its own workspace, and gates merges on tests, evaluations, human approval, and provenance. Any agent can use it over REST, CLI, or MCP.
Stratum reviews the result, not just the diff. Every change must prove itself through evaluation-gated merges — tests, LLM review, your own CI, and your own evaluation criteria — before it can merge.
Both. The hosted beta at app.usestratum.dev is the fastest way to start — join the waitlist for an invite. Or, because Stratum is open source, self-host the whole platform on your own Cloudflare account, where it runs on Workers. Stratum Cloud, a managed tier with billing and SSO, is planned.
No. In layer mode Stratum imports a GitHub repository and keeps it in sync both ways: agents work through Stratum's workspaces and merge gates, and every evaluation verdict lands on the GitHub pull request as a comment and a commit status while your team keeps reviewing there. Forge mode makes Stratum the source of truth with no GitHub involved. Same codebase, same change flow; you choose the level of buy-in.
Stratum is in closed beta, opening in waves — early signups get in first. Join the waitlist to claim your spot, and star the repo to follow along in the open.
