GSoC 2025 - Brian2Wasm: simulations in the browser

Development
1

Hey everyone!

I’m Palash Chitnavis, a GSoC 2025 contributor. This summer, I’ll be working on Project #7 Brian Simulator :: Brian2Wasm: simulations in the browser (175/350h). I’m really looking forward to working with my mentors Marcel Stimberg, Dan Goodman, and Benjamin Evans.

What am I working on?

We already have a repo called Brian2Wasm that lets users run Brian2 code directly in the browser. My goal is to turn this early demo into a practical and easy-to-use tool for the wider community. I’ll be working on releasing a conda package, adding tests, improving the build pipeline, and making the setup smoother so users can run and share simulations with minimal effort.

Would love to hear any suggestions, feedback, or ideas you might have related to this direction!

Looking forward to learning from and collaborating with this amazing community :smile:

Using this space to track my progress on Brian2WASM during GSoC 2025.

Week 1
Added CLI support to Brian2WASM, allowing users to switch between running the same script with Brian2 or Brian2WASM.

Week 2
Set up a Pixi environment for Brian2WASM to simplify installation by automating EMSDK setup.
