Key differences
Hosting Model & Vendor Lock-in
Firebase is a proprietary Google Cloud service with no self-hosting option. Appwrite is 100% open source (BSD-3) and designed for self-hosting, with a newer managed cloud offering. Firebase locks you into Google; Appwrite gives you data ownership.
Database Technology
Firebase uses Firestore (NoSQL document store) with client-side SDK access and security rules. Appwrite provides a document database with server-side SDKs and permissions. Firebase is more flexible for complex queries; Appwrite is more structured.
Ecosystem & Maturity
Firebase is industry-standard with massive community, documentation, and Google Cloud integration. Appwrite is newer with a smaller but growing community focused on privacy and self-hosting.
Pricing
Firebase
Spark (Free): 1GB storage, 10GB/mo bandwidth. Blaze (Pay-as-you-go): $0.18/GB storage, $0.06/100K reads. Can get expensive with high traffic. Google Cloud pricing applies.
Appwrite
Self-hosted: Free (you pay for hosting ~$5-20/mo). Appwrite Cloud: Freemium with paid tiers starting ~$15/mo. More predictable than Firebase usage-based pricing.

Questions
Can I migrate from Firebase to Appwrite?
Yes, but it requires work. Firestore and Appwrite use different data models. You'll need to export Firebase data, transform it, and import to Appwrite. Auth migration is easier with standard OAuth providers.
Is Appwrite production-ready?
Yes. Many companies use Appwrite in production, especially for self-hosted deployments. The managed cloud offering is newer but growing. Firebase is more battle-tested at massive scale.
Which has better offline support?
Firebase has superior native offline support, especially for mobile apps. Appwrite provides offline capabilities through client SDKs but isn't as mature.
What are hosting costs for self-hosted Appwrite?
You can run Appwrite on a $5-20/mo VPS (DigitalOcean, Linode) for small apps. Larger apps may need $50-100/mo+. Firebase costs depend on usage and can spike unexpectedly.
Which is better for mobile apps?
Firebase is better for mobile-first apps due to mature SDKs, excellent offline support, and Crashlytics integration. Appwrite works well for mobile but has a smaller ecosystem.
