Supabase: complete definition in AI for SMEs

Supabase is an open-source database platform built on PostgreSQL, adding turnkey features: authentication, file storage, edge functions (serverless code), realtime (live change listening) and an automatic REST API. It is the open-source alternative to Firebase, designed for teams that want a complete backend without managing servers.

What it changes for an SME

Supabase is often the data foundation of SME AI projects:

• Database: storing leads, documents, agent logs, evaluation results — all in a structured SQL schema;
• Auth: user management, roles and permissions without coding authentication;
• Edge functions: executing server-side code (AI API calls, data processing) without hosting a server;
• Realtime: a dashboard that updates live when an agent processes a new lead.

What you should know

Supabase is not an AI tool per se — it is the foundation on which AI tools (agents, workflows, dashboards) build. Its advantage: everything lives in the same ecosystem, edge functions run milliseconds from the data, and Row Level Security (RLS) protects data access.
