WebAssembly Micro Runtime
A Bytecode Alliance project
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 several execution modes including interpreter, Ahead-of-Time compilation(AoT) and Just-in-Time compilation (JIT). The 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 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 (~85K for interpreter and ~50K for AOT) and low memory usage
- 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 sample
- Linux SGX (Intel Software Guard Extension) support, ref to document
- Source debugging support, ref to document
- XIP (Execution In Place) support, ref to document
- Berkeley/Posix Socket support, ref to document and sample
- Multi-tier JIT and Running mode control
- Language bindings: Go, Python, Rust
Wasm post-MVP features
- wasm-c-api, ref to document and sample
- 128-bit SIMD, ref to samples/workload
- Reference Types, ref to document and sample
- Bulk memory operations, Shared memory, Memory64
- Tail-call, Garbage Collection, Exception Handling
Supported architectures and platforms
The WAMR VMcore supports the following architectures:
- X86-64, X86-32
- ARM, THUMB (ARMV7 Cortex-M7 and Cortex-A15 are tested)
- AArch64 (Cortex-A57 and Cortex-A53 are tested)
- RISCV64, RISCV32 (RISC-V LP64 and RISC-V LP64D are tested)
- XTENSA, MIPS, ARC
The following platforms are supported, click each link below for how to build iwasm on that platform. Refer to WAMR porting guide for how to port WAMR to a new platform.
- Linux, Linux SGX (Intel Software Guard Extension), MacOS, Android, Windows, Windows (MinGW)
