The causal coordination layer for autonomous software.
Git was built for human turn-taking. Stitch is the real-time coordination layer for AI coding agents — with zero source code custody.
Built for individual developers. Scaled for enterprise.
Stitch Jam
Multiplayer Runtime for Coding Agents
Coordinate agent swarms on one repository in real time.
Stitch Federation
Cross-Repo Software Upgrades
Ship breaking releases that migrate themselves across customer repos.
Getting an agent to code is easy. Getting two to agree is the hard part.
Isolated Context
Agents run in separate terminal tabs, unaware of each other's changes until merge time.
Silent Overwrites
Concurrent edits overwrite each other, producing expensive merge conflict explosions.
Proactive Coordination
Stitch claims scopes before generation starts. Agents review uncommitted drafts in real time.
Stitch Jam
Watch Claude Code and Cursor build on one repo in real time. When Cursor touches leased code, Stitch stops the collision.
Stitch Federation
Ship breaking releases that migrate themselves across customer repos — without touching their code.
Publish Update
Release includes automated migration recipes.
Local Migration
Customer agent runs the recipe against private tests.
Verified Proof
Cryptographic proof returned. Zero customer code shared.
See a breaking change migrate across three repos.
An API provider pushes a breaking change to three customer repos. Local agents fix calls, verify tests, and return proof.
Three steps to coordinated agents.
Run the CLI
Start the zero-config coordinator in your repository.
Connect Your Agents
Launch Claude Code, Cursor, or Codex.
Build in Parallel
Agents claim tasks and test without collisions.
Frequently Asked Questions
Common questions about Stitch coordination and privacy. Read the white paper for mathematical invariants.
When an agent starts a task, it claims the relevant files or symbols. If another agent tries to edit those same parts, Stitch immediately rejects the claim and redirects that agent.
No. Stitch only relays lightweight coordination signals — claims, queries, and test attestations. Your code stays strictly in your local repository.
Any harness with MCP or terminal support works out of the box, including Claude Code, Cursor, Windsurf, Codex, Gemini Code, Aider, and Goose.
API providers publish upgrade recipes to customer repos. Local customer agents run the migration and verify tests, returning cryptographic proof without sharing proprietary customer code.
Start with two agents.
Run Stitch on your next release or internal project. Your code never leaves your machine.
