Hi, I just wish to update that: since fullsoak@v0.9.0, support for Cloudflare Workers has been added in experimental mode :)
Enabling this on Cloudflare Workers has been a rather challenging journey, due to the fact that the file-system APIs (that FullSoak uses) are not available on Cloudflare Workers. In fact there are still some bugs to squash, but I'm excited to share an early PoC: https://github.com/fullsoak/cloudflare-workers-examples
