When we built AngleSharp.Js, the goal was simple: bring DOM-aware JavaScript execution into .NET so your headless parser could interact with modern, JS-heavy web apps.
With AngleSharp.Wasm 1.0.0, we're taking headless browser capabilities in .NET one step further by bringing WebAssembly module execution directly into the AngleSharp ecosystem.
Here is why this matters for .NET developers building scrapers, crawlers, and testing suites:
- Handling WASM-Powered Web Apps 🌐
More production web apps are offloading critical client-side computations (crypto, image processing, complex data parsers) to WebAssembly modules. AngleSharp.Wasm allows your .NET headless instance to execute those modules natively during parsing. - Full Headless Fidelity 🧩
Just like AngleSharp.Js handles dynamic DOM manipulation via scripts, AngleSharp.Wasm ensures your headless engine doesn't break when a web app relies on dynamic Wasm binaries to hydrate its state or render content. - Lightweight .NET Native Execution 🚀
Instead of spinning up a heavy, memory-intensive headless Chromium instance via Playwright or Selenium just to run a client-side Wasm module, you can keep your parsing stack light, fast, and 100% inside .NET.
As the web shifts more logic from traditional JS to WebAssembly, headless tooling in .NET needs to evolve alongside it.
