javaperf — questions

Answers built from our own checks of this server.

Why is there no uptime for javaperf?
javaperf 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 javaperf was installed 44 times last week.
How do I connect javaperf?
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 javaperf straight from npm; nothing to host, nothing to sign up for.
How many people use javaperf?
The npm package javaperf was installed 44 times in the last week. Week over week that is -48%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is javaperf open source?
Yes — written in TypeScript and 8 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.
