Supabase is the open-source Firebase alternative: Postgres database, auth, instant REST/GraphQL APIs, realtime subscriptions, and edge functions in one platform. UK developers get a full backend without managing infrastructure. The free tier includes 500MB database and 50,000 monthly active users. Pro starts at $25/month. It can be self-hosted for full data control, and cloud deployments support EU regions — important for UK GDPR compliance. Supabase suits UK startups that want Postgres power with Firebase-style DX, especially when avoiding vendor lock-in matters.
