WebAssembly Micro Runtime

Notice: We've Arrived

WAMR has arrived to its new home. Honestly, you shouldn’t see much of a difference. Github’s tools mean that the repositories and forks you have of the WAMR project should continue to work with no changes. However, if you run into any difficulty at all the table below should help. – If you are still stuck, please do send us an email to this google message group and we’ll do our best to help.

Delayed Domain Transfer

There is just one exception at the moment and that is the domain wamr.dev. This hasn’t been moved over yet. However, we hope this will happen soon.

Ongoing CI/CD Pipeline checks

We are continuing to double-check that all of our CI/CD pipelines / Github Actions continue to work as expected. This work is ongoing. If you encounter any issues, please do let us know via the google group.

Build WAMR | Build AOT Compiler | Embed WAMR | Export Native API | Build Wasm Apps | Samples

WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime with small footprint, high performance and highly configurable features for applications cross from embedded, IoT, edge to Trusted Execution Environment (TEE), smart contract, cloud native and so on. It includes a few parts as below:

• VMcore: A set of runtime libraries for loading and running Wasm modules. It supports rich running modes including interpreter, Ahead-of-Time compilation(AoT) and Just-in-Time compilation (JIT). WAMR supports two JIT tiers - Fast JIT, LLVM JIT, and dynamic tier-up from Fast JIT to LLVM JIT.
• iwasm: The executable binary built with WAMR VMcore which supports WASI and command line interface.
• wamrc: The AOT compiler to compile Wasm file into AOT file
• Useful components and tools for building real solutions with WAMR vmcore:
  • App-framework: A framework for supporting APIs for the Wasm applications
  • App-manager: A framework for dynamical loading the Wasm module remotely
  • WAMR-IDE: An experimental VSCode extension for developping WebAssembly applications with C/C++

Key features

• Full compliant to the W3C Wasm MVP
• Small runtime binary size (core vmlib on cortex-m4f with tail-call/bulk memory/shared memory support, text size from bloaty)
  • ~58.9K for fast interpreter
  • ~56.3K for classic interpreter
  • ~29.4K for aot runtime
  • ~21.4K for libc-wasi library
  • ~3.7K for libc-builtin library
• Near to native speed by AOT and JIT
• Self-implemented AOT module loader to enable AOT working on Linux, Windows, MacOS, Android, SGX and MCU systems
• Choices of Wasm application libc support: the built-in libc subset for the embedded environment or WASI for the standard libc
• The simple C APIs to embed WAMR into host environment, see how to integrate WAMR and the API list
• The mechanism to export native APIs to Wasm applications, see how to register native APIs
• Multiple modules as dependencies, ref to document and sample
• Multi-thread, pthread APIs and thread management, ref to document and sample
• wasi-threads, ref to document and
