One session layer for every AI coding agent on your machine. Start a conversation in Claude Code and continue it in Codex, OpenCode or Antigravity, from any directory.
Each tool only lists the sessions it started itself, in the directory you launched it from. agentbridge makes every session show up in every tool, and shares new work back across all of them. Your tools' own session files are never modified.
Install
pipx install agentbridge-rs # or: uv tool install agentbridge-rs
Or with Cargo: cargo install --git https://github.com/45Harry/agentbridge.
The command is agentbridge either way. Linux, macOS and Windows.
Quick start
agentbridge init # see which sessions are on this machine (read only)
agentbridge auto install # share new and changed sessions in every new terminal
agentbridge sync # make this directory's sessions visible in all tools
Then resume any session in the tool you like:
claude --resume <id>
codex resume <id>
agentbridge resume <id> opencode
agentbridge resume <id> antigravity
Every command that writes accepts --dry-run. agentbridge unsync removes
exactly what agentbridge created and nothing else.
Commands
Supported tools
* Shared databases: agentbridge backs them up first, tags its own rows, and won't write while the tool is open.
Copies are titled origin tool · session name · start time · id, so one
conversation is easy to spot in every tool's list.
