Does Metric Beyond work on the D&D Beyond app?

No. Metric Beyond is a web browser extension and thus only works on the supported browsers, i.e. Safari, Chrome and Firefox. It is not possible to modify the D&D Beyond app, only D&D Beyond themselves can do that.

Can you add support for my favorite browser?

Maybe! Send me an email at or add an issue to Metric Beyond's GitHub repository (if you know how to), and I'll see what I can do.

I found a bug/something that isn't converted, what can I do?

If you find a bug or something that isn't being converted then you can send me an email at or add an issue to the GitHub repository, with as much details as possible. A screenshot of the bug or missing conversion is a minimum.

Can I help?

Sure you can, sweetheart! Although I don't need help with the code, you can definitely help by sending feedback, suggestions of features, or even a little tip if you can.
