Supabase
Supabase is the open-source backend built on PostgreSQL: Database, Auth, APIs, and Storage, popular as the foundation for AI app builders.
Supabase is an open-source alternative to Google's Firebase, built on PostgreSQL. You get a database, authentication, automatically generated APIs, file storage, and serverless functions all in one place — the building blocks of almost every modern app.
Supabase recently gained prominence as the backend for AI app builders: Lovable and many Bolt projects store their data there by default. Additionally, development teams use it as the foundation for SaaS products and mobile backends. Its strength: real Postgres with SQL instead of a proprietary data model, plus vector storage for RAG applications without an additional service.
Compared to Xano, you'll need SQL and development knowledge, but you'll save money: The Pro plan starts at $25 a month, and as an open-source project, Supabase can be self-hosted if necessary. To be honest: you need to understand Row Level Security and database design, otherwise your data could quickly become exposed.
The top choice for developers and technical founders who want a complete backend without infrastructure maintenance. No-code teams without SQL knowledge are better off with Xano.
