# Features

In this chapter, you can see the complete list of features that WAMR support. And for each feature, we have an example followed demonstrating the usage of such a feature.

## IWASM features

### 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 work 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](https://github.com/WebAssembly/WASI) for the standard libc
* [The simple C APIs to embed WAMR into host environment](https://wamr.gitbook.io/document/wamr-in-practice/tutorial/language-embedding/embed_wamr), see [how to integrate WAMR](https://wamr.gitbook.io/document/wamr-in-practice/tutorial/language-embedding/embed_wamr) and the [API list](https://github.com/TianlongLiang/wasm-micro-runtime/blob/main/core/iwasm/include/wasm_export.h)
* [The mechanism to export native APIs to WASM applications](https://wamr.gitbook.io/document/wamr-in-practice/features/export_native_api), see [how to register native APIs](https://wamr.gitbook.io/document/wamr-in-practice/features/export_native_api)
