The WebAssembly GC proposal repository, a branch of the official WebAssembly spec repo for discussing and prototyping garbage collection support in WebAssembly. It contains the proposal documents, a modified specification, a reference interpreter, and a conformance testsuite.

Use cases

• understand how garbage collection works in WebAssembly
• read the Wasm GC proposal specification
• test Wasm engine conformance against the GC testsuite
• implement GC support in a WebAssembly runtime
• track the status of the Wasm GC standardization proposal
• experiment with a reference interpreter for Wasm GC

When to choose

• you are implementing or evaluating Wasm GC support in a compiler or runtime
• you need the authoritative spec documents and testsuite for the GC proposal
• you want to follow or contribute to WebAssembly standardization

When to avoid

• you need a production WebAssembly runtime or toolchain rather than a spec
• you want a finished, ratified standard with stable tooling rather than a proposal repo
• you are looking for a garbage collector for a general-purpose language outside Wasm
