Edge Functions

Edge Functions are server-side TypeScript functions, distributed globally at the edge—close to your users. They can be used for listening to webhooks or integrating your Supabase project with third-parties like Stripe. Edge Functions are developed using Deno, which offers a few benefits to you as a developer:

• It is open source.
• It is portable. Supabase Edge Functions run locally, and on any other Deno-compatible platform (including self-hosted infrastructure).
• It is TypeScript first and supports WASM.
• Edge Functions are globally distributed for low-latency.
