Supabase
FeaturedThe open source Firebase alternative.
Founded in 2020 by Paul Copplestone and Ant Wilson through Y Combinator, Supabase was built as the open-source alternative to Google's Firebase. While Firebase locks developers into a proprietary NoSQL database, Supabase is built on top of PostgreSQL — the world's most trusted open-source relational database — giving developers all the power of Postgres with the developer experience of a modern backend platform. Supabase raised a $200 million Series C at a $2 billion valuation in 2024 and has grown to over 1 million databases on its platform. It is particularly popular among AI developers because it offers pgvector, a Postgres extension for vector similarity search that is essential for building retrieval-augmented generation (RAG) applications.
