  • Share: the WebAssembly Hub is a registry for Wasm Envoy extensions where users can store and share their extensions. 
  • Discover: the WebAssembly Hub is a meeting place for the community to share and consume Wasm Envoy extensions. 
  • Deploy: the WebAssembly Hub provides all the configuration updates that users need in order to add an extension to Envoy, Istio, Gloo and any other Envoy-based products that support Wasm. 

WebAssembly Hub use cases include:

  • Security: users can enhance the security of their service mesh environments by discovering and deploying Web Application Firewall (WAF) extensions in just a few steps.
  • API Transformation: users can modernize legacy SOAP backends by building and consuming transformation extensions that expose REST APIs to their consumers. 
  • Collaboration: developers can build and publish their custom extensions to potential users. 

Wasm is currently supported by the service mesh Istio and by's Gloo Enterprise 1.0, a production-ready enterprise-grade API gateway, as well as by Envoy Proxy itself. Other Envoy-based service meshes are expected to offer Wasm support in the near future.
