You have to press "decompile" for each individual class.

And "You have 2 of 3 free decompilations remaining today."

Instead of spending $3/mo, just download jd-gui or luyten.

Thank you for your feedback. Indeed, jd-gui it's an option here, but web version doesn't require any installation and any knowledge of java. In addition, free version has 3 de-compilations per day, which should be enough for majority of use cases. Pro version doesn't have this limitation

Neither does using jd-gui, you just launch it... also why would someone use a Java class decompiler if they don't have any knowledge of Java?

> which should be enough for majority of use cases

I don't see how it is, it's enough for something super small, but even something like... a small Minecraft mod will easily exceed 3 classes.
