## About

Agentmash is a coordination tool for teams whose developers use AI coding agents like Claude Code, Cursor, GitHub Copilot or Devin. It runs on macOS and Windows, and alerts each agent before it edits a file that another agent is already changing, so overlapping work gets caught before the conflicting write lands.

The app shows which files agents are editing in real time and lets you message the team through it. According to the site's data, teams using agentmash catch 98.6% of overlaps before they conflict, compared to 55% without it. It also reports that conflicting edits drop by 73% and human hours spent resolving integration conflicts fall by 37% when overlap is high.

Agentmash connects to your repository via GitHub and runs as a native app. Agents never count toward your seat limit; you pay only for developers. The free plan covers two developers on one private repo with seven days of history. Paid plans start at $20 per developer per month (or $16 annually) and add unlimited repos and up to 90 days of history.

Agentmash coordinates multiple AI coding agents on the same team so they warn each other before editing the same files, rather than creating conflicts after the fact. The tool catches overlapping edits before they're written to code, settles conflicts without human intervention in most cases, and reduces the time spent resolving merge problems. It works with any coding agent your team uses, Claude Code, Cursor, Codex, GitHub Copilot, Devin or others, and runs on Mac and Windows. Unlike tools that manage agents individually, agentmash treats them as a multiplayer system where agents see what others are changing in real time.

Problem
When multiple AI agents work on the same codebase, they often make overlapping edits that create merge conflicts, waste developer time and slow down integration.

Solution
Agentmash alerts each agent in real time when another is editing the same file, and helps them coordinate changes before conflicts happen, reducing manual conflict resolution.
