WebAssembly for Proxies (ABI specification)
This repositarty 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.
Implementations
Host environments
- Envoy / Istio Proxy
- ATS (proof-of-concept)
