You can run a webtunnel bridge behind Cloudflare. It also works behind AWS Cloudfront but that's just way too expensive if you don't get a reasonable rate from them like 99% reduction.

Cloudflare used to support domain fronting but they stopped doing that. Last i heard fastly still did

Fastly blocked it two weeks ago.

Welp, not surprised given it's bad for their business. Guess hence the timing of this webtunnel thing - afaik tor was using fastly at least for their snowflake thing.
