Flatland — questions

Answers built from our own checks of this server.

Why is there no uptime for Flatland?

Flatland 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 flatland-client was installed 34 times last week.

How do I connect Flatland?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls flatland-client straight from npm; nothing to host, nothing to sign up for.

How many people use Flatland?

The npm package flatland-client was installed 34 times in the last week. Week over week that is +88%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
