Best Open-Source Alternatives to Firebase
Backend-as-a-Service with realtime databases and serverless functions. Compare verified, self-hostable open-source replacements for Firebase with live GitHub repository telemetry, SPDX license audits, and production Docker Compose configurations.
Why teams are ditching Firebase
Typical Cost: $25 - $200+ / project / monthProprietary NoSQL lock-in; unpredictably steep bills on read/write spikes; lack of relational SQL queries.
Financial Impact: Migrating from Firebase to Self-Hosted Supabase
* Excludes enterprise SSO add-ons & usage overages
* Commodity Hetzner / DigitalOcean compute instance

db-data:Frequently Asked Questions: Firebase Alternatives
What is the best open-source alternative to Firebase?
The top-rated open-source alternative to Firebase is Supabase, boasting over 111,414 GitHub stars and an active open-source community. It runs on TypeScript, Go, PostgreSQL and provides complete data ownership under the Apache-2.0 license.
Why are teams moving away from Firebase?
Key pain points include Proprietary NoSQL lock-in; unpredictably steep bills on read/write spikes; lack of relational SQL queries. In addition, typical costs range around $25 - $200+ / project / month, which escalates rapidly as team sizes grow.
Can I self-host an alternative to Firebase with Docker Compose?
Yes! Every alternative on OSSMatrix includes production-ready Docker Compose definitions. You can spin up the service on any Linux VPS or local server with a single 'docker compose up -d' command.
How much money can our company save by self-hosting?
Most companies cut their software recurring expenses by 90% to 98%. Rather than paying per-seat licensing fees month after month, you only pay for your underlying commodity compute (typically $10-$40/month on Hetzner or DigitalOcean).
