Show HN: SpeedAPI – An API Toolkit (github.com)

It's mainly geared towards massive-scale real-time applications. On top of that, it offers IDE autocomplete for TypeScript users and employs a low-overhead binary encoding.

It uses a dedicated description language (a schema) that compiles down to a number of target programming languages, though at the moment only JS/TS is supported with immediate plans for Elixir. The compiler itself is implemented in Python.

Feedback is highly appreciated!
