SyncBeta
Sync keeps one agent setup for every coding agent your team uses. You write instructions, skills, MCP servers, permissions and hooks once in the repo’s .cedr/ folder, and cedr sync writes each agent’s own files from it: AGENTS.md, Claude Code’s .mcp.json and settings, Codex’s config, Cursor and Copilot rules, Gemini CLI, opencode and Antigravity settings. Your CI fails when someone edits a generated file by hand or forgets to run cedr sync, and the Sync page in the app shows every repo’s state.
Sync never calls a configuration safe or compliant. It reports what differs and which rules a repo breaks.
