When to Choose Fly.io vs Supabase
The question that matters: “In what situation will I regret choosing A over B after 3 months?”
Fly Machines start in under 3 seconds, enabling zero-downtime rolling deploys without load balancer warm-up delays or deployment scheduling windows.
Supabase RLS policies enforce tenant data isolation at the database level, serving a single Postgres table to all customers without application-layer filtering code.
Anycast Networking directs players to the nearest Global Region, cutting latency from 120ms to 30ms. Auto-scaling Fly Machines absorb sudden player count spikes seamlessly.
Edge Deployment runs identical app instances across 30+ regions from one Docker image. Private Networking isolates databases per region - no separate cloud accounts required.
Supabase Realtime broadcasts Postgres table changes via WebSocket to subscribed clients, adding live collaboration or notification features without a separate message broker.
Supabase Auth integrates with Postgres RLS through the built-in auth.uid() function, wiring user identity to database row permissions without a separate identity service.

Strengths & Limitations
Evaluative strengths and weaknesses: not feature lists
- +Runs full-stack apps, not just static sites, on the edge
- +Uses lightweight Firecracker MicroVMs for better isolation
- +Built-in global request routing and private networking
- +Postgres clusters deploy globally alongside your application
- +Generous free tier includes compute, storage, and databases
- −Steeper learning curve than PaaS like Heroku or Render
- −Limited region availability compared to major cloud providers
- −Documentation can be sparse for advanced or niche use cases
- −No built-in serverless functions; requires running a server
- −Monitoring and observability tools are less mature than AWS/GCP
- +Direct PostgreSQL access with full SQL and extension support
- +Auto-generated REST and GraphQL APIs from your database schema
- +Open source core allows for self-hosting and no vendor lock-in
- +Integrated row-level security (RLS) for fine-grained data access
- +Generous free tier includes two organizations and 500MB database
- −No built-in serverless functions for complex backend logic (requires Edge Functions)
- −Realtime server is single-region, potentially increasing latency for global users
- −Steeper learning curve for developers unfamiliar with PostgreSQL and RLS
- −Managed platform lacks some advanced Postgres configurations (e.g., pgbouncer)
- −Cloud Functions are Deno-based, which has a smaller ecosystem than Node.js
