Hi everybody, happy to see our CheerpJ demo is appreciated.

CheerpJ is a WebAssembly-based JVM that can run unmodified Java 8 and Java 11 applications. Java 17 will be supported later in year.

I am the lead developer of CheerpJ and CTO of Leaning Technologies. AMA.

Cool stuff!

Hey I saw a typo on https://cheerpj.com/cheerpj-core-licenses/, it says "liencesees" halfway the page

Thanks for spotting this, we'll get it fixed ASAP

Would it work for a JavaFX app? (not sure I'd be able to shrink the bundle size enough for it to make sense though)

JavaFX is not yet supported, but we plan to get it to work soon.

The issue here is that there is very little Java in JavaFX, it's mostly native C++ code. This makes it actually quite similar to the LWJGL library used by Minecraft.

Our plan is to use for JavaFX the same technology we have developed for LWJGL.

thanks! that's kinda what I figured. And now it's not part of Java's "core" so it'd make sense if it was "out of scope"

How much is the licensing for a small company wanting external users to use it to use an app hosted online?

Small Business licenses will be available with the release of CheerpJ 4.0, expected in mid April 2025.

They will allow self-hosting and will be priced on a per application / per website basis. They will be priced to be affordable and ensure that CheerpJ enjoys a wide reach.

If you are interested before the release, please do get in touch (info@leaningtech.com).
