Supabase, an open-source alternative to Firebase, has announced its beta pricing with three tiers: Free for up to four hobby-level projects, Pro at $25 per project per month for more serious projects, and Usage based for those needing more resources than the Pro tier. The company aims to provide a predictable pricing model without shock bills at the end of the month while supporting users' growth. Supabase offers a free tier for students, hobbyists, and early adopters, with plans to issue credits for alpha, beta, and Launch Week sign-ups.
