Show HN: Faasta – A self-hosted Serverless platform for WASM-wasi-HTTP in Rust

alexboehm Friday, April 25, 2025

I've just released an early version off my project I've been working on for a few months now and would love some feedback.

https://github.com/fourlexboehm/faasta

I was surprised there isn't yet an open/source and standards compliant way to host wasi-http functions in a way that takes advantages of WASM, a multi tenanted application.

If you're not familiar with wasi, Compared to something like AWS Lambda, this approach is much more efficient as a single process can serve 1000s of function invocations concurrently and asynchronously, instead requiring an entire VM.

This is still early days for the project, but feel free to download the cli utility with cargo install cargo-faasta.

Feel free to test deploying functions on my hosted instance at https://website.faasta.xyz.

The service is free to use and currently supports deployments via GitHub OAuth, with a limit of 10 functions per GitHub account.
