That's a really cool implementation! I hope I'll have some time soon to have a peek at the code. I am honestly a bit surprised to see that none of the major cloud providers are even thinking to leverage WASM and WASI for serverless…

Do you plan to support custom domains and SSL certificates for self-hosted Faasta deployments, or will that be handled externally via reverse proxies?

Since there is no LICENSE in the repo, I assume this will not be an open source project? Will it have an open core or similar license?

You could link to faasta.xyz in github about and add EXAMPLES there.
The lambdas should be able to be accessible via http(s) e.g.
https://square.faasta.xyz/3 => 9
https://faasta.xyz/square/3 => 9
Great idea if done right!

Bun likely has a larger footprint than this but it's also gaining lots of traction: https://bun.sh/docs/runtime/loaders
How might this project differentiate itself from Bun as it grows? Because Bun aims to be compact and fast (fast being the priority in their case).

Unfortunate name collision with FASTA the bioinformatic sequence file format
