Regex Lab — questions

Answers built from our own checks of this server.

Why is there no uptime for Regex Lab?

Regex Lab runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.

Is Regex Lab open source?

We cannot say either way: written in JavaScript and 1 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
