OtherFunc is a serverless function platform for languages no major cloud provider (to my knowledge) supports. There are currently implementations of brainfuck, Forth, APL, Lisp (Scheme-like), and BASIC.

The interpreters are written in Rust, compiled to a single Wasm binary, and deployed on Cloudflare Workers. You can finally write Forth and publish it as an HTTP endpoint. You can see some examples on the showcase page: https://otherfunc.com/showcase

- brainfuck can make HTTP requests. The tape is extended to 33,000 cells with a memory-mapped I/O region. You write a URL to cells 30,000+, set a method byte, trigger execution, and the response appears in cells 31,000+. The Brainfuck program to do this runs ~35,000 characters, but it works.

- The interpreters use a coroutine/yield pattern for I/O instead of async. When code needs to make an HTTP call or access KV storage, the interpreter suspends with an IoRequest, the Worker performs the fetch, then resumes execution with the response.

- There's an MCP server so AI assistants can deploy functions directly. The thought was, if an LLM is writing all your code anyway, the language it is written in doesn't really matter. But you probably don't want to waste your tokens writing bf either.
