Library Mode

A simple home for the things you build. Library Mode keeps every version of your project, lets you go back to any of them, and gives you a page to share what you made. No developer vocabulary, no team ceremony. Works from inside Claude Code and OpenCode.

For people using Library Mode

1. Sign in at the website with your email (we send you a link; no password).
2. On your computer: uv tool install librarymode (or pipx install librarymode), then librarymode connect. A browser tab opens — click Allow. Library Mode also adds itself to Claude Code and OpenCode.
3. In your project folder, say "save this to Library Mode" to your coding tool, or run librarymode save -m "what changed".
4. On the website: see every version, go back to one, or make the project public to share it.

Commands: librarymode save, librarymode get NAME, librarymode latest, librarymode versions, librarymode restore N, librarymode share, librarymode open, librarymode projects, librarymode status, librarymode setup-agents.

For whoever runs it

uv venv -p 3.12 .venv && uv pip install -e ".[dev]"
.venv/bin/pytest                      # end-to-end suite (starts a real local server)
LIBRARYMODE_BASE_URL=http://localhost:8080 .venv/bin/librarymode-server   # local run; emails land in ./data/outbox

Deploy: fly launch once (creates the librarymode_data volume), then fly deploy. See fly.toml for the environment, scripts/backup_to_b2.sh for nightly backups, and docs/ for the map and the decisions.
