WASM support is not there yet but it's on the roadmap and we had it in our mind since the beginning of the project, and have made our dev choices accordingly.
So yes it could be used in a serverless platform like Cloudflare workers. Our startup time is a huge advantage here (20ms vs 600ms for Chrome headless in our local tests).
Regarding v8 in Cloudflare workers I think we can not used directly, ie. we still need to embed a JS engine in the wasm module.
But of course we plan to add others features, including
- tight integration with LLM
- embed mode (as a C library and as a WASM module) so you can add a real browser to your project the same way you add libcurl
