Nothing serious here today

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

Nexo — questions

Answers built from our own checks of this server.

Why is there no uptime for Nexo?
Nexo 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 nexo-brain was installed 892 times last week.
How do I connect Nexo?
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 nexo-brain straight from npm; nothing to host, nothing to sign up for.
How many people use Nexo?
The npm package nexo-brain was installed 892 times in the last week. Week over week that is -85%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
