This one has been a long-time coming. It's one of our most requested features. We spent a long time getting the Developer Experience right - we investigated several approaches (Containers, Isolates, WASM), and eventually landed with Deno.
Big shout-out to the Deno team. Their open source and DX-focused philosophy made it an obvious choice in the end. We've wrapped their open-source runtime to make the Supabase experience as integrated as possible, from the local CLI development, to realtime logs on the Dashboard. Edge Functions are still Experimental, so make sure you send your feedback to make the experience even better.
We'll have a few of the team in the discussion ready to answer any questions.
