I’ve been starting to feel that the regex101 logo needs a slight refresh. Seeing as how I barely know how to use Paint, I am not the best at designing this. Would anyone care to help?


I have implemented a set of mitigations that, together, seem to mitigate this (still ongoing) attack. If you notice any odd behavior, please do reach out to me, as I don't want any legitimate users to be negatively impacted by this change.


I don’t know why they are doing this, but I have recorded over 5000 ips. Further mitigations are in place, hopefully things stabilize now.


Regex101 is currently under, what looks like, a ddos attack.

Thank you for your patience! Regex101 is back up and running.


I am running some database migrations over the weekend, expect some lag and downtime when saving and accessing entries.

You can now use the .NET flavor on the website! Enjoy!


I’ve just deployed the latest version, which is (almost) a total rewrite under the hood. Please be patient while I iron out bugs and kinks!


The JavaScript flavor now highlights subpattern groups that matched in the subject string like all other flavors on the site 🎉
