When two agents edit the same file, one silently overwrites the other — wasting tokens and hours of time. AgentCollision coordinates your agents to prevent that collision, saving you money and painful mistakes.
AI agents ship code faster than ever — but every parallel session is a chance for silent overwrites. Two agents edit the same file. One wins. The other's work vanishes. No warning, no merge. You find out when the build breaks — then you burn the tokens to regenerate the lost work and the hour to track down what happened. Every collision is billed twice.
Each session gets its own workspace and holds short-lived leases on its files. Parallel agents work side by side without conflict. When one finishes, the next proceeds automatically. Solo developers or full teams — no work is ever lost, and no tokens or hours wasted redoing it. AC pays for itself the first time it prevents a single go-around.
A single lightweight Go daemon runs alongside your AI tools. It hands out short-lived leases on files and regions of your codebase — turning overlapping edits into a clean, ordered queue.
Hooks fire over a Unix socket in under a millisecond. Your agents don’t slow down. They just stop stepping on each other.
Whether you're a solo vibe coder or a team running 20 agents in parallel — AgentCollision handles it.
Coordination happens in under a millisecond. Your agents never slow down — they just stop stepping on each other.
Solo mode keeps everything local — no cloud, no accounts. Team mode syncs only coordination state, never your code. No telemetry by default.
Claude Code, Cursor, Windsurf, Cline, Aider, and anything that supports MCP. One layer for your entire stack.
Define subsystems in .agentcollision/subsystems.toml with glob patterns. Commit it. Share it. Done.
Every prevented collision is work you didn't lose and tokens you didn't burn redoing it. agc savings and the dashboard put a conservative dollar figure on it — with the math shown.
If an agent crashes or goes silent, its lease expires automatically. No stale locks. No manual cleanup required.
File paths are HMAC-hashed on your machine before leaving. The coordinator never sees your code, file names, or directory structure.
The VS Code extension tells AgentCollision which files you have open. Any AI agent that tries to write to those files is refused — no more silent overwrites of work in progress.
Agents talk to each other directly — same machine, same team, or cross-org via JWS-signed federation. Broadcast a scope check before refactoring; wait for objections; ship safely.
Subscribe external systems to lease, policy, and spend-cap events with HMAC-signed deliveries. Point a webhook at hooks.slack.com and AgentCollision auto-formats events as Slack messages — no relay process required.
A colored dot in your menu bar shows daemon health at a glance: green when clean, yellow on contention risk, red on trouble. One command to install: agc menubar install.
Cedar-backed rules let admins decide who can edit what, when, and how. Set lease TTLs, restrict subsystems by role, gate risky paths behind approval — enforced before any agent writes a byte.
Every lease, message, and policy decision is recorded with actor, scope, and before/after state. Stream it to your SIEM or browse it in the dashboard — useful for SOC 2, useful for post-incident review.
See what every team member is editing in real time. Set coordination policy once and enforce it across machines. Zero-knowledge architecture — your code never leaves your laptops.
Create a team at dashboard.agentcollision.com — or accept a teammate's invite. No credit card for the 14-day trial.
One copy-paste command, shown right in your dashboard. Works on macOS, Linux, and Windows. Auto-detects your AI tools and wires them up.
Launch as many AI sessions as you want — solo or across your team. Each gets its own workspace. No conflicts, no lost work.
Install free for solo work. Upgrade to Team ($8/user/mo) when you add a second machine or invite teammates. 14-day trial on all team plans. No credit card required.
