Backend + Hosting Without Vendor Lock-in
Firebase locks you into Google's ecosystem. Runsite gives you open-source tools, EU hosting, and full data ownership.
Best Firebase alternative: quick answer
The best Firebase alternative depends on your stack, but for EU-based indie developers and small startups, Runsite is the strongest option: GDPR-compliant hosting in Frankfurt (eu-central), predictable EUR pricing with hard spending caps, and a permanent free tier that needs no credit card. Unlike Firebase, your data never leaves the EU or falls under the US CLOUD Act, so compliance is the default rather than a configuration step.

Firebase vs Runsite: What You Need to Know
Ship a prototype over a weekend, and Firebase feels like magic. Google's all-in-one backend was built for exactly that speed.
Firestore, Firebase Auth, Cloud Messaging, and Hosting form a tightly integrated ecosystem, and the free Spark plan covers small projects comfortably. The real-time capabilities are genuinely useful for mobile and web apps. The catch shows up later. Everything that made the fast start possible becomes vendor lock-in: Firestore's proprietary query model, Firebase-specific auth SDKs, and Cloud Functions tied to Google Cloud mean your code cannot run elsewhere without substantial rewrites. GDPR compliance adds its own tax, requiring a Google Cloud DPA, careful region configuration, and ongoing vigilance about which services process data where.
Runsite uses standard PostgreSQL, Docker containers, and S3-compatible storage, all portable to any other provider. Teams that have outgrown Firebase's proprietary model, or that need straightforward EU compliance without navigating Google's data processing agreements, get a cleaner foundation. You bring your own auth and realtime layer, but you own every piece of your stack.
