Honestly this looks like it sits in the useless middle ground between “proper CI that has all the features you expect” and “just write a Python/Deno script or whatever”. I can’t see what you gain.

Also you say “no painful YAML pipelines” but it uses YAML??

Relatively minor for source code forges.

The reasons everyone uses GitHub:

• Free, even for private repos. No ads.
• Free CI - this is huge. Nobody else does this because it costs Microsoft around $100m/year to provide.
• It’s quite good.

If anyone can ever compete with that then I doubt network effects will keep people there.

Interesting idea, but your trick is never really going to help (you can store up to 255 bytes instead of 254). Also always using 256 bytes for every string seems wasteful.

I think LLVM’s small string optimisation is always going to be a better option: https://joellaity.com/2020/01/31/string.html
