Nothing serious here today

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

pgbrake — questions

Answers built from our own checks of this server.

Why is there no uptime for pgbrake?

pgbrake 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 pypi package pgbrake was installed 1 099 times last week.

How do I connect pgbrake?

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 pgbrake straight from pypi; nothing to host, nothing to sign up for.

How many people use pgbrake?

The pypi package pgbrake was installed 1 099 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 pgbrake open source?

Yes — it is published under the MIT licence, written in Python 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.
