Spin 2.0, an open-source tool to build and run serverless WebAssembly apps, gets support for WebAssembly components, improves performance and developer experience, and lays the foundation for Wasm portability across runtimes and implementations.
Spin has been using WebAssembly components under the hood since version 1.5. In version 2.0, you can leverage all properties supported by Wasm components, including the possibility of composing components created using any language supporting Wasm.
