Frequently Asked Questions
Is flanner really free?
Yes. The CLI, MCP server, and local web UI are open source under the MIT license and free to use forever. You can read, fork, and self-host the whole thing from GitHub.
How do I install it?
Run pip install flanner, then flanner init in your project. It auto-registers with Claude Code and Codex.
What is Flanner Cloud?
A hosted tier for teams: shared workspaces, unlimited history on Postgres/S3, and links to Jira, Notion, and chat. It's on the roadmap, not available yet. Join the waitlist to hear when it lands.
Do I need an account to use flanner?
No. The local tool stores everything in a SQLite database on your machine and works entirely offline. An account only comes into play with Cloud, later.
Which AI assistants does it work with?
Claude Code and Codex out of the box (via CLAUDE.md and AGENTS.md), plus any assistant that speaks the Model Context Protocol.
Can I contribute?
Absolutely, it's open source. Open an issue or PR on GitHub.
