Slowplan — questions

Answers built from our own checks of this server.

Why is there no uptime for Slowplan?

Slowplan runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package slowplan.

How do I connect Slowplan?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls slowplan straight from npm; nothing to host, nothing to sign up for.

Is Slowplan open source?

Yes — it is published under the MIT licence, written in Go, 0 stars on GitHub and 5 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
