Part of the idea comes from liking the simplicity of older CGI-style models: put code in a place, map it to a route, and keep the deployment model understandable. FastFN takes that in a more modern direction with multiple runtimes, local dev, OpenAPI, and a simpler path for mixed API + frontend projects.

It supports Python, Node, PHP, Lua, Rust, and Go in one project.

This started as a weekend project that got out of hand. I am thinking were to take it next now.
