Reviewer scorecard
“The most mature AI developer platform. Assistants API, function calling, and the Playground are all well-designed. Documentation is extensive.”
“Auth, database, storage, edge functions, and vector search in one platform. For side projects and MVPs, Supabase eliminates the need for 5 different services.”
“Reliability has improved dramatically. The rate limits are generous on paid tiers. The Assistants API is finally stable enough for production.”
“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.”
“OpenAI has the largest ecosystem of developers and integrations. Even if other models catch up, the platform moat is real.”
“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.”
