This repository contains specification of the low-level Application Binary Interface (ABI) and conventions to use between L4/L7 proxies (and/or other host environments) and their extensions delivered as WebAssembly modules.
The event-driven streaming APIs and convenient utility functions were originally developed for the WebAssembly in Envoy project, but they are proxy-agnostic, and consumers can use the same Proxy-Wasm extensions across different proxies.
The latest and widely implemented version of the specification is v0.2.1.
There is a Proxy-Wasm on Slack. Feel free to join and engage with the community.
