Platforms like supabase or netlify use deno for serverless functions, so they should have been supporting it more.
Aren't Supabase or Netlify customers of Deno Deploy?
I don't think so, I think they just used deno as a runtime with their own cloud.
One of them should fork if it's cheaper than migrating because a lot of Deno code is not portable.
Correct, we (Supabase) operate our own infra and don't use Deno's hosted services.
Netlify used to be but isn't anymore: https://www.netlify.com/blog/edge-functions-firecracker-micr...
Technically, it's a separate product called Deno Subhosting, not exactly Deno Deploy. (But no longer used: https://www.netlify.com/blog/edge-functions-firecracker-micr....)
Uh no. The lack of users killed Deno.
