WasmEdge is a cloud-native WebAssembly runtime hosted by the CNCF. It is widely used in edge computing, automotive, Jamstack, serverless, SaaS, service mesh, and even blockchain applications. Featuring AOT compiler optimization, WasmEdge is the fastest WebAssembly runtime on the market today.
- Cloud-native runtime
- JavaScript or DSL runtime
- Serverless function-as-a-service in public clouds
- Software defined vehicles and AIoT
- Reactive functions for SaaS
WasmEdge can be embedded into cloud-native infrastructure via its SDKs in C, Go, Rust, and JavaScript. It is also an OCI compliant runtime that can be directly managed by CRI-O and Docker tools as a lightweight and high-performance alternative to Docker.

In order for WebAssembly to be widely adopted by developers as a runtime, it must support "easy" languages like JavaScript. Or, better yet, through its advanced compiler toolchain, WasmEdge could support high performance DSLs (Domain Specifc Languages), which are low code solutions designed for specific tasks.
WasmEdge can act as a cloud-native JavaScript runtime by embedding a JS execution engine or interpreter. It is faster and lighter than running a JS engine inside Docker. WasmEdge supports JS APIs to access native extension libraries such as network sockets, tensorflow, and user-defined shared libraries. It also allows embedding JS into other high-performance languages (eg, Rust) or using Rust / C to implement JS functions.
The image classification DSL is a YAML format that allows the user to specify a tensorflow model and its parameters. WasmEdge takes an image as the input of the DSL and outputs the detected item name / label.
A chatbot DSL function takes an input string and responds with a reply string. The DSL specifies the internal state transtions of the chatbot, as well as AI models for language understanding. This work is in progress.
WasmEdge works with existing serverless or Jamstack platforms to provide a high-performance, portable and secure runtime for functions. It offers significant benefits even when it runs inside Docker or microVMs on those platforms.
WasmEdge is ideally suited to run on mission-critical edge devices or edge networks.
YoMo is a high-performance data streaming framework for far edge networks. WasmEdge is integrated into YoMo to run user-defined workloads, such as image classification along a factory assembly line.
seL4 is a highly secure real-time operating system. WasmEdge is the only WebAssembly runtime that can run on seL4, and it runs at native speed. We also provide a management tool to support the OTA deployment of wasm modules. This work is still in progress.
WasmEdge can support customized SaaS extensions or applications using serverless functions instead of traditional network APIs. That dramatically improves SaaS users' and developers' productivity.
It is also known as 飞书 aka the Chinese Slack. It is created by Byte Dance, the parent company of Tiktok.
