About SimplestAPI
What is SimplestAPI?
SimplestAPI is a backend platform for Lovable, Bolt, v0, or Replit apps that provides a live API with a database, logins, and AI search.
What SimplestAPI does
SimplestAPI connects a database, logins, and AI search in under 2 minutes without database setup. Users describe what an app needs in plain English or paste sample JSON data to infer tables, types, foreign keys, and relationships. The platform delivers full REST and CRUD endpoints with pagination, filters, and sort, alongside vector search and end-user logins via JWKS. Every project includes an LLM-ready docs link that agents in Claude, ChatGPT, or Cursor can read and write to directly.
