Reviewer scorecard
“Run any Docker container globally with `fly launch`. The Machines API for programmatic VM creation is uniquely powerful.”
“Auth, database, storage, edge functions, and vector search in one platform. For side projects and MVPs, Supabase eliminates the need for 5 different services.”
“Global deployment is its strength. For edge-first architectures, Fly.io solves distribution better than anyone.”
“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.”
“Apps running close to users is the future. Fly.io's Machines API enables new categories of distributed applications.”
“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.”
