StackPath EdgeEngine can do JS with WASM support for PHP, C, C++, Go, Python, Perl, Rust + others https://www.stackpath.com/products/edgeengine/

Cloudflare Workers also supports Wasm and so supports all those languages, too, in theory.

In practice, though, Python's, Perl's, and PHP's Wasm support is extremely immature and probably won't meet the needs of a production web application today. Go is closer but still presents challenges.

Rust seems to have by far the most mature Wasm tooling (and Rust support is built-in to the Workers CLI tool). C and C++ are also reasonably usable.

GCP has Python functions that can run either based on Pub/Sub messages or in response to HTTP requests (Flask). Similar in some ways.

AWS Lambda

This is closer to lambda@edge which only supports nodejs
