Wattindex — questions

Answers built from our own checks of this server.

Why is there no uptime for Wattindex?

Wattindex 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/wattindex was installed 291 times last week.

How do I connect Wattindex?

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/wattindex straight from npm; nothing to host, nothing to sign up for.

How many people use Wattindex?

The npm package @reneturcios/wattindex was installed 291 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 Wattindex 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.
