Reviewer scorecard
“The API is clean, the React Email integration is brilliant, and deliverability is excellent. Replaced SendGrid in 20 minutes and never looked back.”
“Auth, database, storage, edge functions, and vector search in one platform. For side projects and MVPs, Supabase eliminates the need for 5 different services.”
“Young company with a smaller scale than SendGrid or Postmark. But the developer experience is so much better that it's worth the risk for startups. Monitor deliverability closely.”
“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.”
“Building beautiful transactional emails used to be painful. React Email components make it feel like building a web page. Game changer for my client projects.”
“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.”
