Kanzo: A 5k-Line Rust Kanban Binary With MCP for Claude Code and Codex
allmudi · reddit · 2026-10-27
A developer open-sourced Kanzo, a self-hosted kanban board shared by humans and coding agents — roughly 5k lines packed into a single 4.3 MB Rust binary with SQLite inside, idling at 4 MB RAM. The design philosophy is radical smallness, a counterpoint to today's Docker-plus-three-services task boards.
- Starts in 3 ms; a 3,000-task board loads in 17 ms
- Ships an MCP server whose tools cost agents only 800 tokens with short replies — tell Claude Code or Codex "take the next task from kanzo" and it moves the card and comments as it works
- No accounts, no cloud, no Docker; syncs across machines via your own private git repo
- One-line install on macOS/Linux, runs on a Raspberry Pi; PRs welcome — deleting code counts as a feature
