Component Model Implementations is one of 4 APIs that [Component Model](https://apis.io/providers/component-model/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Bytecode Alliance, Implementations, Runtimes, and Toolchains. The published artifact set on APIs.io includes an API reference.

A landscape of toolchains and runtimes that implement the Component Model, including Wasmtime, Jco, wit-bindgen language bindings, cargo-component for Rust, ComponentizeJS, and Spin for serverless Wasm. These implementations are largely stewarded by the Bytecode Alliance.
