Cloudflare workers can do wasm and js.

I haven't tried with wasm personally because well, it has a limit of 25 mb and I am not sure but last time I read somewhere in their forums about some guy wishing to run golang, it had the issue that wasm could only be 1-2mb and golang's most basic example had it taken 1-2mb so they can't cook anything good.

Of course I can be wrong & I am just too lazy to search that article to remember the facts again.

Cloudflare is literally magic with typescript. I swear, people like to give me that cloudflare example of gambling and show the time where their sales team messed up so hard but If we read that article, I think I can agree with Cloudflare because they were a gambling site... my gripe is that cloudflare could've been more professional, but hey mistakes happen , I genuinely hope that Cloudflare has moved on, Since if I ever create any website, any service whatever, Its most likely going to be on Cloudflare and I just hope that I don't get messed up like that guy.

And also one key thing to note is you should probably not keep the domain itself in cloudflare if you are thaat paranoid and write something in hono if you really want portability (maybe its overkill??) and if you really get messed up like the gambling blog guy then you can easily switch away...

Still ITS way too unlikely to happen I guess.
