Supabase has secured $200 million in a Series D funding round, pushing its valuation to $2 billion, just seven months after raising $80 million. The growth is attributed to the rising trend of vibe coding, which aligns with Supabase's offerings as an open-source alternative to Firebase. Founded in 2020, the company has grown its developer community to over 1.7 million, making it a popular backend choice for AI applications. Investors in this round include Accel and Coatue, highlighting the increasing interest in open-source database solutions.
