Skulpt vs TeaVM
Both stand on code transpilers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Web
Pick Skulpt for browser-based Python learning or for adding Python execution to a webpage without server-side support. Look elsewhere if your project depends on Python features that Skulpt has not implemented or only partly supports.

TeaVM offers a free route from JVM-compiled code to browser targets, with build integrations, optimization and debugging support. Its constrained APIs and partial Java library mean projects must be checked and adapted before deployment.

Skulpt: what it does well
- Runs Python code entirely in the browser.
- Requires no preprocessing, plugins, or server-side support.
- Can be added directly to HTML or embedded in a webpage.
- Supports custom modules created and hosted by users.
- The runtime may be licensed under MIT or PSFLv2.
What to know first
- Some Python language features are missing or only partly implemented.
- The dual runtime license may not cover surrounding build-processing or testing code.
- The interactive feature is described as new and still getting off the ground.
TeaVM: what it does well
- Compiles Java, Kotlin and Scala output
- Produces JavaScript and WebAssembly
- Maven and Gradle project integrations
- JavaScript and browser API interop
- Source maps support debugging
What to know first
- Only a limited Java library subset is implemented
- Reflection, resources, class loaders and JNI are restricted
- WebAssembly requires HTTP serving
- Code may need rewriting for compatibility
