Reviewer scorecard
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Auth, database, storage, edge functions, and vector search in one platform. For side projects and MVPs, Supabase eliminates the need for 5 different services.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“The free tier is one of the most generous in the industry. The AI SQL editor is surprisingly good for non-SQL developers. Only concern: vendor lock-in on their specific Postgres extensions.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
“Supabase proves that open-source alternatives can match and exceed proprietary platforms. They're building Firebase, but better, and you can self-host if you want.”
