FAQ

Is Kanna free?

The Kanna software itself is free and open source. Underlying provider costs (Claude, Codex) depend on your account.

Does Kanna upload my code anywhere?

No. The agent runs locally — claude or codex CLI subprocesses on your machine. Only the prompts and tool outputs you explicitly send go to the model.

Does PTY mode actually save money vs the SDK?

If you have a Claude Pro/Max subscription, yes. PTY mode billing rolls into the subscription. SDK mode bills at API rates per-token.

Can I use both Claude and Codex in the same chat?

Yes — switch providers mid-chat from the composer. Previous turns remain unchanged; the new turn uses the picked provider.

Where is my data stored?

$KANNA_HOME (defaults to ~/.kanna/). All chats, projects, OAuth tokens, and settings live there.

Can I run Kanna headless?

Kanna is a web UI. The server runs headless; a browser is required for interaction. For automation, use the Claude/Codex CLIs directly.

Windows support?

PTY mode is macOS/Linux only. SDK mode works on Windows via WSL but is not officially supported.
