Reviewer scorecard
“Auth, database, storage, edge functions, and vector search in one platform. For side projects and MVPs, Supabase eliminates the need for 5 different services.”
“150ms cold starts for sandboxed code execution. Essential for AI agents that need to run untrusted code safely.”
“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.”
“AI agents running code need sandboxing. E2B's micro-VMs are purpose-built for this use case.”
“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.”
“Safe code execution for AI agents is critical infrastructure. E2B is building the sandbox layer that every agent needs.”
