Open-Source & Self-Hosted Alternatives to Firebase Backend
Google's proprietary BaaS known for vendor lock-in and unpredictable monthly bill spikes.
Why Migrate Away from Firebase Backend?
Firebase locks you into proprietary NoSQL Firestore queries and Google Cloud pricing. When queries run wild, cloud bills explode. Self-hosted alternatives give you standard PostgreSQL with relational power, full vector search for AI, instant REST/GraphQL APIs, and zero read/write per-operation pricing.
