AWS Lambda is rated higher (4.1 vs 4.0). Supabase Edge Functions run TypeScript serverless functions at the edge using Deno. Close to your Supabase PostgreSQL database for low-latency operations. Free tier available. AWS Lambda is the original FaaS service — run code without servers. Supports 15+ runtimes, 1M free requests/month, and integrates deeply with 200+ AWS services. Triggered by S3, DynamoDB, API Gateway, and more.

Supabase Edge Functions
Pros
- + 500,000 free invocations per month — enough for real workloads before paying anything
- + Zero-configuration access to Supabase Postgres, Auth and Storage from inside functions
- + Same open-source edge runtime locally and in production, with hot reload and CI deploys
- + Transparent per-million invocation pricing ($2 per million over quota) with spending limits available
- + Global distribution with optional pinning to the database region
Cons
- - Value largely depends on being a Supabase customer — weak standalone proposition
- - Cold starts are documented; not suited to heavy synchronous work in request paths
- - Deno/Node boundary still blocks some Node packages and native modules
- - No public uptime SLA below the Enterprise tier
- - External log drains cost $60 per drain per project
AWS Lambda
Pros
- + Zero idle cost with a free tier that covers small products: 1M requests and 400,000 GB-seconds monthly
- + Graviton pricing at $0.0000133334 per GB-second undercuts x86 by roughly 20%
- + Automatic multi-AZ scaling with a 99.95% per-region SLA and no capacity planning
- + Deep event integration across AWS services, with three form factors (Event/Web Functions, MicroVMs)
Cons
- - Per-request and GB-second pricing gets expensive against committed compute at steady high utilization
- - Cold starts — hundreds of milliseconds to seconds depending on runtime — with provisioned concurrency as an extra meter
- - 15-minute execution limit and payload caps make it wrong for long-running batch work
- - AWS-specific event plumbing creates real lock-in; distributed event chains are hard to debug
