Supabase Edge Functions runs on the same V8 isolate primitive as Cloudflare Workers and is fully open-source (https://github.com/supabase/edge-runtime). We use the Deno runtime, which supports Node built-in APIs, npm packages, and WebAssembly (WASM) modules. (disclaimer: I'm the lead for Supabase Edge Functions)
In Head in the Zed CloudDepending on your criteria, a server like https://github.com/supabase/edge-runtime could be a fit.
In Building untrusted container images safely at scaleCongrats on the launch! It's great to see more companies build serverless offerings on top of Deno.
I lead Supabase Edge Functions product, a similar offering built on top of Deno runtime too. We have open-sourced our runtime (https://github.com/supabase/edge-runtime), and it's self-hostable. It supports NPM, node built-ins, pluggable storage, and web sockets. We also have a built-in API for AI inference (https://supabase.com/blog/ai-inference-now-available-in-supa...)
Supabase Edge Runtime is easy to self-host (works great as a multi-threaded JS web server). We love community contributions :) Let us know if you would like to collaborate.

Here's our experience with Supabase at https://automark.io (Next.js + Supabase).
- First of all, Supabase let us launch fast which was amazing. Super powerful Postgres features without the pain of self-hosting (or so we thought).
- We started out using their hosted product for both our DB, storage, auth, and functions.
- Functions have a critical bug that prevent us from using in development so we decided to move to our own API servers: https://github.com/supabase/edge-runtime/issues/212
- Now, the connection between our API servers and the database was slow (a few hundred ms per query), so we moved to self-hosting Postgres which was pretty painful. We tried to use https://github.com/supabase/postgres, but the documentation was very lacking and we had to make a bunch of modifications to get it to work. After we got

it working, it was pretty smooth though - pretty easy to implement backups, etc.
- Our latest issue has been around auth where the cookie name options change. We've spent hours debugging random cookie issues deep in the auth framework (they finally released `@supabase/ssr` which is pretty decent, but we're still thinking about moving to handling auth on our side so we know and can debug the logic).
One thing to mention: although our requirements didn't quite fit Supabase and we ran into these issues, we weren't locked into their hosting. We were able to completely move off of it over the course of a few weeks, but continue using the self-hosted version. This is a huge benefit over something like Firebase or Amplify. We're pretty satisfied with Supabase as an open source project, but not as satisfied with Supabase hosting.
It previously ran on Deno, but now we run our own edge runtime!

We self-host the Edge Runtime now:

Hi Mark, hosted Supabase Edge Functions would still run on Deno Deploy, so those limitations would still exist. However, we plan to introduce file system access via integration with Supabase Storage. This is still a rough idea stage, maybe we'll have a solid answer in a couple of months :)
For dynamic imports, we haven't looked into it since Supabase users haven't requested it. If you can open an issue on Edge Runtime repo [0] and explain how you intend to use them, we can probably work on a solution.
