After months of work, I just released the first public version of Saikuro, a cross-language invocation fabric that lets different languages call each other without RPC boilerplate.
TypeScript, Python, Rust, and C# adapters, all talking to a shared Rust runtime.
Why Rust for the runtime?
- Portable (runs anywhere)
- Strongly typed
- Predictable under concurrency
- Safe to embed
- Fast enough to sit in the middle
Basically: "I want this to run everywhere and not explode"
What it looks like in practice:
TypeScript: provider.register("math.add", (a, b) => a + b)
Python: client.call("math.add", [10, 32]) returns 42
No HTTP server. No IDL file. No stub generator. Just function calls across languages.

Still early but core pieces work end-to-end. Feedback and "why did you design it this way" discussions welcome.
@nellowtcs wow, this looks really cool!
Your TCP example is neat, specially if I can make it work across the network. But your In-memory example is killer! Have the process running in the same space and have two separate programming languages, each with their own capabilities, talk to each other. Well done!
