Always great to see uses of CheerpJ in the wild. Make sure to join our Discord to show the community what you are building. https://discord.leaningtech.com

Running legacy educational Java applets, especially around math and physics, has been a longstanding popular use case of our CheerpJ Applet Runner extension, running Java bytecode in the browser via WebAssembly. I am not sure how to feel ab

As another commenter pointed out this is similar to our WebVM ( https://webvm.io ) , although this one is based on v86 so it will be less performant. Although the x86 virtualization angle is powerful we think that native WebAssemb

As a matter of fact WebVM and BrowserPod share the same kernel, the difference is all on the performance side. WebVM uses x86 virtualization and hence has a significant performance penalty, with the upside of running any existing software w

The architecture is a fairly straightforward WebAssembly-native monolithic kernel. Most of the complexities come from making things work well within the browser constraints for real world, large apps. We have quite a bit of experience on th

Our technology is much more general that WebContainers, and it's based on a Linux-compatible WebAssembly kernel. It also supports real command line tools, including git, bash and the complete set of busybox utilities. The version of Cl

I can confirm non-Java languages work as expected. I've personally tried Kotlin, and IIRC some user from the community reported Clojure to be working as well. Consider joining our Discord for help: https://discord.leaningtec

Not something I tried myself, but conceptually if it's Java it should work. CheerpJ Just-In-Time compiles Java bytecode at runtime, so it makes no difference if the classes come from JAR files or are dynamically generated.

Shameless plug: we solved the opposite problem, running any Java application in the browser via WebAssembly: https://labs.leaningtech.com/blog/cheerpj-4.3 And yes, it does run Minecraft as well :-) https://b

Thanks :-) We have been building WebAssembly-based products for a while now, so for us it's second nature. But I think you are right, most developers, even experienced ones, have not yet come to grasp the fully capabilities of the Web

Thanks for sharing. I see how this could impact heavy user, but there is always the option of authenticating via a non-ephemeral auth key as a potential workaround. It's not integrated in the public WebVM UI, but it is supported by the

Hi, lead dev of WebVM here. Can you link to the specific change that affects ephemeral devices? I cannot find this reference in the article. Keep in mind that we also plan to offer builtin networking in the near future, we are developing th

Do you have any specific test case that you would consider "very challenging" on the compatibility side? I'd be curious to check if BrowserPod can support that already.

Only node is supported as of version 1.1, but the next version is fully focused on command line tooling (git, bash, ssh, grep, ...). See the launch blog post for our full timeline: https://labs.leaningtech.com/blog/brow

This is not correct. You are using WebVM here, not BrowserPod. WebVM is based on x86 emulation and JIT compilation, which at this time lowers vector instructions as scalar. This explains the slowdowns you observe. WebVM is still much faster

As far as I know lots of EU countries don't allow double citizenship. This implies that, even when having the prerequisites, acquiring the new citizenship for the sake of voting also mean losing the old citizenship altogether. At least
