Open-Source Firebase Alternatives
Developers often seek Firebase alternatives due to concerns over vendor lock-in, unpredictable pricing at scale, and limited control over infrastructure. Open-source options allow self-hosting, customizability, and cost predictability, making them attractive for projects that need to avoid proprietary dependencies.
When evaluating alternatives, consider factors like self-hosting feasibility, data portability, real-time capabilities, and the maturity of the ecosystem. Solutions like Supabase and Turso offer distinct trade-offs in terms of database paradigm, latency, and sync features, so the choice depends on your application's specific needs.

Frequently asked questions
Is Supabase free to use?
Supabase offers a generous free tier with up to 500 MB database, 1 GB storage, and 50,000 monthly active users. For larger scale, paid plans start at $25/month, and you can also self-host the open-source version for full control.
Can I self-host these Firebase alternatives?
Yes, both Supabase and Turso are open-source and can be self-hosted. Supabase provides Docker images and a self-hosting guide, while Turso's core is open-source and can be run on your own infrastructure.
How hard is it to migrate from Firebase to Supabase?
Migration difficulty depends on your use of Firebase features. Supabase provides a migration guide for Firestore to PostgreSQL, but you'll need to adapt queries and security rules. Authentication and storage migrations are straightforward with provided tools.
Does Turso support real-time updates like Firebase?
Turso focuses on edge data and sync, not real-time subscriptions. For real-time features, you'd need to pair it with a separate solution like WebSockets or use Supabase which has built-in real-time capabilities.
