## AI overview

Supabase open-sources Edge Runtime, an MIT-licensed Rust web server based on Deno Runtime 1.32+ for self-hosting Supabase Edge Functions. It supports TypeScript, JavaScript, and WASM functions, works with the Supabase CLI, and improves local development through hot reloading, JWT verification, import maps, custom environment variables, and serving all local functions. The runtime also improves development and production parity and can enforce memory and execution-duration limits.
