I have some existing Python code that I would like to run in the browser, without having to rewrite it in JavaScript. Has anyone used any of the tools that allow the use of Python in the browser? There seem to be two classes of such tools: 1. Python interpreters written in JavaScript. These include Brython [1], Skulpt [2] and Batavia [3]. 2. Compilers (a.k.a. transpilers) that convert Python code directly into JavaScript. I would expect this to provide better performance than an interpreter, but perhaps be a less accurate Python implementation. This seems to be the approach taken by Transcrypt [4]. Has anyone used any of the above, or similar tools? How did you find them in terms of compatibility, performance etc?

I'm an unaffiliated 3rd party (with a ton of interest) but from what I hear, Python's BeeWare project could use contribs. They have a number of endeavors that are all really neat. Some of them: 1. Toga: cross-platform + mobile, OS-native (looks like a "standard" app for that device) GUI toolkit. https://github.com/pybee/toga 2. VOC: transpile Python bytecode to JVM bytecode. The goal is to be able to run arbitrary Python code within a JVM, with the intention of extremely performant, native deployment to Android. https://github.com/pybee/voc 3. Rubicon: running python through objective C for OS X and iOS. https://github.com/pybee/rubicon-objc 4. Batavia: a Javascript implementation of the Python virtual machine. https://github.com/pybee/batavia 5. Briefcase: packaging Python as a native app, particularly mobile but eventually desktop execu

They also have an in-browser bytecode runner: https://github.com/pybee/batavia
