as far as I know wazero is the only zero-dependency Wasm runtime written in Go. This is not just one of those "written in $LANG" kinda deal: most other runtimes require linking against a native library; this in turn plays against a lot of the killer features of Go, such as good tooling, easy cross-compilation, goroutines [0]; so, not requiring Cgo means a team may bring wazero to their Go project without a second thought. As for other features, we may not be as bleeding edge as other projects, but we are a rather tiny team. If you expect support for WASI (preview 1) we have it :) we try to concentrate our effort on high-quality support of stable specs. EDIT: oh, and a huge shout-out to Stealthrocket, they are building a lot of cool stuff on top of wazero: - wzprof, a wasm profiler integrating with pprof https://github.com/stealthrocket/wzprof https://github.com/stealthrocket/wzprof - timecraft, a wasm time-traveling runtime https://github.com/stealthrocket/timecraft https://github.com/stealthrocket/timecraft [0] see "CGO is not Go" https://dave.cheney.net/2016/01/18/cgo-is-not-go https://dave.cheney.net/2016/01/18/cgo-is-not-go
