Nothing serious here today

Today is the operative word: we check Errorcatalog every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Errorcatalog — questions

Answers built from our own checks of this server.

Why is there no uptime for Errorcatalog?

Errorcatalog 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 @reneturcios/errorcatalog was installed 293 times last week.

How do I connect Errorcatalog?

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 @reneturcios/errorcatalog straight from npm; nothing to host, nothing to sign up for.

How many people use Errorcatalog?

The npm package @reneturcios/errorcatalog was installed 293 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Errorcatalog open source?

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