Review behavior, not just the diff. Nothing merges on trust.
Stratum is the open git forge for teams shipping agent-written code. It works with any agent, and every change proves itself — tests, evaluations, provenance — before it merges. Start on Stratum Cloud 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.
Get started fast on Stratum Cloud, our managed setup, or self-host the whole platform in your own infrastructure. 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 — run it on Stratum Cloud or self-host the whole platform in your own infrastructure. Your code stays yours: it never leaves your infrastructure.
Every commit in Stratum can carry the record behind it: which agent wrote it, which model was used, a hash of the prompt that shaped it, and the evaluation evidence that gated the merge — structured, queryable, and attached to the merge.
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 repository runs isolated in its own storage, so one repo's problem can't cascade to another. The fastest way to start is Stratum Cloud, a managed setup we run for you (coming soon). Prefer to keep everything in-house? Self-host the whole platform in your own infrastructure and pay only for the infrastructure you use.

Stratum reviews the result, not just the diff. Every change must prove itself through evaluation-gated merges — tests, LLM review, static analysis, and your own evaluation criteria — before it can merge.
Both. Stratum Cloud (coming soon) is the fastest way to start — a managed setup we run for you. Or, because Stratum is open source, self-host the whole platform in your own infrastructure so your code never leaves it.
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.
