## Inspecting

- **WebAssembly Code Explorer** | [online tool](https://wasdk.github.io/wasmcodeexplorer/)  

  A simple binary explorer with neat binary code highlighting.

- **wasm-opt** | part of [`Binaryen`](https://github.com/WebAssembly/binaryen)  

  - Color output of s-expression format:  

    `wasm-opt --print test.wasm`

  - Plot the callgraph using `Graphviz`:  

    `wasm-opt --print-call-graph test.wasm | dot -Tpng -o callgraph.png`

  - Dump DWARF debug info sections:  

    `wasm-opt --dwarfdump test.wasm`

  - Print function metrics:  

    `wasm-opt --func-metrics test.wasm`

- **wasm-decompile** | part of [`WABT`](https://github.com/WebAssembly/wabt), [article](https://v8.dev/blog/wasm-decompile)  

  `wasm-decompile` decompiles a wasm binary into readable code. It generates output that tries to look like a "very average programming language" while still staying close to the wasm it represents.

- **wasmdec** | [repo](https://github.com/wwwg/wasmdec), [online tool](https://wwwg.github.io/web-wasmdec/)  

  Converts WebAssembly binaries to C. Similar to `wasm2c`.

- **wasp** | [repo](https://github.com/WebAssembly/wasp)  

  Generate callgraphs, CFG and DFG graphs for wasm functions.

- **wasm-objdump** | part of [`WABT`](https://github.com/WebAssembly/wabt)  

  Print low-level details about a `.wasm` binary and each of its sections.

- **wasm-nm** | [repo](https://github.com/fitzgen/wasm-nm)  

  List the imported, exported, and private function symbols defined within a `.wasm` binary.

## Static analysis

- **Twiggy** | [repo](https://github.com/rustwasm/twiggy)  

  Code size profiler, analyzes a binary's call graph.

- **Manticore** | [repo](https://github.com/trailofbits/manticore), [article](https://blog.trailofbits.com/2020/01/31/symbolically-executing-webassembly-in-manticore/)  

  Symbolic execution of WebAssembly binaries.

  

- **Octopus** | [repo](https://github.com/pventuzelo/octopus)  

  Security analysis framework for WebAssembly modules and Smart Contracts.

  

- **Wassail** | [repo](https://github.com/acieroid/wassail)  

  A toolkit to perform both lightweight and heavyweight static analysis of WebAssembly modules.

- **wasm-opcodecnt** | part of [`WABT`](https://github.com/WebAssembly/wabt)  

  Count wasm opcode usage statistics.

## Manipulating (optimization, transformation, instrumentation)

- **wasm-opt** | part of [`Binaryen`](https://github.com/WebAssembly/binaryen)  

  - Transform binary for asynchronous execution (read more in [this article](https://kripken.github.io/blog/wasm/2019/07/16/asyncify.html)):  

    `wasm-opt test.wasm --asyncify -O3 -o asyncified.wasm`

  - Instrument binary for dynamic execution tracing:  

    `wasm-opt test.wasm --instrument-memory --instrument-locals --log-execution -o instrumetred.wasm`

- **wizer** | [repo](https://github.com/bytecodealliance/wizer)  

  Don't wait for your Wasm module to initialize itself, pre-initialize it! Wizer instantiates your WebAssembly module, executes its initialization function, and then snapshots the initialized state out into a new WebAssembly module.

- **wasm2c** | part of [`WABT`](https://github.com/WebAssembly/wabt/blob/main/wasm2c/README.md), 

[article 1](https://kripken.github.io/blog/wasm/2020/07/27/wasmboxc.html), 

[article 2](https://petersalomonsen.com/articles/wasm2c/wasm2c.html)  

  Takes a WebAssembly module and produces an equivalent (and runnable) C source and header.

  

- **wasm-snip** | [repo](https://github.com/rustwasm/wasm-snip)  

  Replaces a WebAssembly function's body with an `unreachable`.

- **wasmonkey** | [repo](https://github.com/jedisct1/wasmonkey)  

  Magically turns exported WASM functions into imported functions.

- **wasm-meter** | [npm](https://www.npmjs.org/package/wasm-metering), [repo](https://github.com/ewasm/wasm-metering)  

  Injects metering into webassembly binaries. This counts computation time for a given program in units of `gas` (and allows limiting it).

- **CROW** | [repo](https://github.com/KTH/slumps/tree/master/crow)  

  The Wasm superdiversifier. It takes C source code or LLVM bitcode as input and generates several functionally equivalent, but diverse Wasm binaries.  

## Dynamic analysis (tracing, profiling)

- **wasm3-strace** | [wapm](https://wapm.io/package/vshymanskyy/wasm3), [repo](https://github.com/wasm3/wasm3)  

  Structured, seamless tracing of arbitrary WebAssembly/WASI execution.

- **Wasabi** | [home](http://wasabi.software-lab.org/), [repo](https://github.com/danleh/wasabi)  

  "WebAssembly analysis using binary instrumentation", a dynamic analysis framework.

- **wasmsign** | [repo](https://github.com/jedisct1/wasmsign)  

  A tool to add and verify digital signatures to/from WASM binaries.

- **swam** | [repo](https://github.com/satabin/swam/)  

  A WASM interpreter with advanced tracing capabilities.

## Source-level debugging

- **Chrome DevTools** | [article](https://developers.google.com/web/updates/2020/12/webassembly)

- **LLDB** | [article](https://hacks.mozilla.org/2019/09/debugging-webassembly-outside-of-the-browser/)

- **wasminspect** | [repo](https://github.com/kateinoigakukun/wasminspect)  

  An interactive and self-contained debugger for WebAssembly/WASI.

## Tool development

- **Tool Conventions** | [docs](https://github.com/WebAssembly/tool-conventions)  

  Documents describing conventions useful for coordinating interoperability between wasm-related tools.

- **wasm2json, json2wasm** | [npm](https://www.npmjs.com/package/wasm-json-toolkit), [repo](https://github.com/ewasm/wasm-json-toolkit)  

  A small toolkit for converting wasm binaries into json and back. Incredibly helpful for experimenting and creating your own transformations.

- **walrus** | [repo](https://github.com/rustwasm/walrus)  

  Rust library for performing WebAssembly transformations in a robust and ergonomic fashion.

- **wasp** | [repo](https://github.com/WebAssembly/wasp)  

  C++ library designed to make it easy to work with WebAssembly modules.

- **Binaryen.js** | [repo](https://github.com/AssemblyScript/binaryen.js)  

  A port of Binaryen to the Web, allowing you to generate WebAssembly using JavaScript.

- **wasm-tools** | [repo](https://github.com/bytecodealliance/wasm-tools)  

  Rust tooling for low-level manipulation of WebAssembly modules.  

    `wasm-smith` test case generator is of particular interest.  

    `wasm-shrink` shrinks a Wasm file while preserving an interesting property (such as triggering a bug).

- **wasm-debug** | [repo](https://github.com/wasmerio/wasm-debug), [crate](https://crates.io/crates/wasm-debug)  

  A runtime-independent Rust library that provides functionality to read, transform, and write DWARF section.
