Coordination layer for AI coding agents

Your team runs multiple AI agents. They should know about each other.

When every developer has their own Claude Code, Cursor, or Copilot instance, agents work in isolation. AgentSync gives each agent real-time awareness of what others are doing, preventing conflicts, eliminating duplicate work, and reducing context bloat.

The reality

Every developer on your team now has an AI agent. Here's what happens without coordination.

Silent overwrites

Alice's agent refactors a function. Bob's agent overwrites it moments later. Neither agent knew the other was working there.

Context bloat

Each agent independently analyzes the same files, eats the same context, and solves problems another agent already solved.

Duplicate work

Two agents implement the same utility function. Three agents fix the same bug. No one knows until merge conflicts appear.

How it works

Agents that know what other agents are doing.

Shared context file

AgentSync maintains a .agentsync/context.md that every agent can read. It lists who's working on what, in real-time.

Line-level locking

When an agent edits lines 10-20, others are blocked from those lines, not the whole file. Granular enough for real collaboration.

Sub-50ms sync

Lock state propagates instantly via WebSocket. Works across machines, networks, and remote development setups.

Context-aware agents

Agents read the context file and self-coordinate. "I see Alice's agent is refactoring auth. I'll work on payments instead."
