Supabase Functions

Serverless platform for running TypeScript at the edge, close to users. Edge Functions execute as Deno-based server-side code with native integration to the host platform's authentication, Postgres database, and object storage, so you can add custom backend logic without managing infrastructure.

Part of the Supabase platform with broad adoption across startups and production apps. Stands out by running on Deno: functions are portable, run locally for development, and deploy to any Deno-compatible environment including self-hosted setups. Unlike generic serverless platforms, functions share the same project context as your database and auth: JWT validation, Row Level Security, and project secrets are built in.

Key capabilities:

• Deno runtime with TypeScript-first support and native npm imports
• Global edge deployment for low-latency execution
• Built-in integration with Supabase Auth, Postgres, and Storage
• Local development parity via Supabase CLI, deploy via Dashboard, CLI, or MCP
• Secrets management and observability from the project dashboard

Engineers use Edge Functions for webhook handlers from Stripe, GitHub, or payment providers, transactional email sending, on-demand Open Graph or image generation, small AI inference tasks or LLM orchestration, and messaging bots for Slack or Discord. The same runtime supports both authenticated HTTP endpoints and public APIs, with connection pooling and serverless-friendly patterns for database access.
