About agentmash

agentmash is a coordination layer for teams whose developers each run AI coding agents, built by a team that includes Damir Iskakov and Alim Dauletbek. Every connected repository gets a shared room, and before an agent edits a file it is told which teammate's agent is changing it, on which branch and why, so it can keep its edit additive instead of creating a merge conflict.

It hooks into Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Devin, OpenCode and 13 other agents. Agents can claim paths, teammates can send a prompt to someone else's agent that runs only after the owner approves, and a team chat reaches every agent. A lobby app runs agents side by side on Mac and Windows, and Linux uses the MIT-licensed CLI. The server stores paths, branches and prompt excerpts, not code, unless a room enables diffs. You pay per developer, never per agent.

It fits teams of three or more running several agents on one codebase. Cursor and Claude Code handle single-user agent work well but do not coordinate across machines, and Git only reveals conflicts at merge time. Sign-in is GitHub-only, GitLab needs a committed room config, and the benefit figures on the site are the vendor's own.

agentmash launched on Product Hunt on November 1, 2026 and sat at #6 on the daily leaderboard late on launch day. Buying tip: two developers are free and Team's first month is free, so measure conflicts on a real sprint before paying.

Pros and cons

Pros

Pricing counts developers only, with unlimited agents
Free for two developers, and Team's first month is free
Server does not see code unless a room enables diffs
Works across many agents, so each developer keeps their own tool
Hooks fail open, so an outage does not block coding

Cons

Sign-in requires GitHub; GitLab and Bitbucket need extra setup
No Linux desktop app, only the CLI
Continue and Zed get MCP tools only, without live edits in the room
Productivity figures on the website are the vendor's own benchmarks
Self-hosting only on the Enterprise plan from $15,000 a year

Common use cases

1Preventing merge conflicts when several developers run agents on one repo
2Asking a teammate's agent to investigate a bug on their branch
3Dividing a feature across agents with path claims
4Keeping agents aware of team rules such as a code freeze before a demo
5Running mixed agent fleets with Claude Code, Codex and Cursor together

Best for

Engineering teams where several developers run AI coding agents on the same repository at once.

Not ideal for

Solo developers or teams that just need a single coding agent (Cursor) without cross-machine coordination.

Integrations

Our take

agentmash solves a specific, growing problem: agents on different machines overwriting each other's work. Teams already running several agents per sprint should try the free tier on one busy repository, while solo developers will get little from it.
