Firebase alternatives: 9 apps ranked by verified data

Facts checked Oct 25, 2026AppBreakup editorialHow we rank

Common reasons people leave Firebase: ties your app closely to Google Cloud, and noSQL query limits often force data duplication. We ranked 9 alternatives by how directly each one replaces Firebase, then by reviews, real visits and how recently each app's facts were checked against its own website. Supabase currently ranks first.
