The open-source GitHub and GitHub Actions alternative that runs entirely on Cloudflare. Git hosting, pull requests, code review and drop-in GitHub Actions CI, with agent tasks, agent code review and plugins for Claude Code and Codex, built for teams of people and AI agents. Deploy it to your own Cloudflare account: no servers, no runner machines, nothing to patch.

Diffinery hosts Git repositories, pull requests with reviews and a merge queue, issues, releases and a container registry, and runs your existing .github/workflows/*.yml files as they are, marketplace actions included. AI coding agents such as Claude Code, Codex and Cursor get accounts of their own, with guardrails the server enforces, and work through a built-in MCP server, the GitHub-compatible REST and GraphQL APIs, git or the CLI. Everything runs on Cloudflare: Workers, Durable Objects, D1, R2, Queues, Workflows and Containers. It is free, open-source software under the Apache License 2.0, and you deploy your own instance to your own Cloudflare account and domain.
Diffinery is built for the way software gets written with agents. Give an agent a goal and get a pull request back from Claude Code or Codex in a sandbox. Have another agent review every pull request for bugs. Open Today each morning to see what needs you, approve, and let pull requests merge on green. Plugins for Claude Code and Codex, an MCP server in the official MCP Registry, editor extensions and gh support bring all of it to the tools you already use. What agents can do on Diffinery ↓

Marketplace actions (uses: owner/repo@ref) are downloaded and run.

Every agent feature is opt-in and sits on top of the Git and CI platform, so a team that uses none of them just has a forge. People bring their own model keys or subscriptions; Diffinery doesn't sell or include model access. The screenshots below are the real pages, taken from a local Diffinery with sample data by scripts/agent-screenshots.mjs, which runs a real agent task, agent review and CI run.
An agent is an account of its own, owned by a person or an organization, with its own tokens. Its role is capped by its owner's, it can't sign in to the web UI, and every commit it makes records who it acts for. The server enforces the same rules over Git, the REST API, MCP and sandboxes:
| Guardrail | What it means |
|---|---|
| No pushes to protected branches | Agents open pull requests instead, unless a branch protection rule allows it. |
| A person approves agent pull requests | At least one approval from a person, even on a branch with no rule. An agent's approval never counts. |
| No merging protected branches | Unless a rule lets agents land through auto-merge once CI and a person agree. |
| Agents can't mark their own CI green | An agent's check results never satisfy requi |
