AWS Lambda is rated higher (4.1 vs 4.0). Supabase is a backend-as-a-service platform providing PostgreSQL databases, real-time subscriptions, authentication, and storage. Built for developers who want PostgreSQL's power without vendor lock-in. 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
Pros
- + Real PostgreSQL with SQL, extensions, migrations, and row-level security — no schema lock-in
- + Generous free tier: 50,000 MAU, 500MB database, unlimited API requests
- + Bundled auth, realtime, S3-compatible storage, APIs, and edge functions on one platform
- + Open source with a documented self-host path — a genuine exit if the managed service stops fitting
- + Transparent, detailed pricing page and 17 AWS regions to place data close to users
Cons
- - Bills grow legs: per-project compute, usage overages, and add-ons (PITR $100/mo per 7 days) stack up
- - Uptime SLA (99.9%) is Enterprise-only; support SLAs need the $599/mo Team plan
- - Free projects pause after a week of inactivity and skip automatic backups
- - Auth, realtime, storage, and functions layers are Supabase-specific to migrate away from
- - Scaling to high concurrency means moving to dedicated compute instances with sharp price steps
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
