Firebase Alternatives in 2026
Ranked by Developers Who've Shipped Both
Firebase is great until it isn't. NoSQL lock-in, unpredictable bills at scale, and zero SQL mean many teams migrate. We've shipped 50+ no-code apps, here's our honest ranking of the best alternatives, with real pricing data.
Supabase
Best overall Firebase alternative
- ✓ PostgreSQL, relational data done right
- ✓ Open-source, self-hostable
- ✓ Real-time subscriptions built in
- ✓ Auth, storage, and edge functions included
- ✗ Newer ecosystem than Firebase
- ✗ Self-hosting requires DevOps effort
PocketBase
Best for small projects & prototypes
- ✓ Single binary, zero infrastructure
- ✓ Completely free and open-source
- ✓ Zero config, instant setup
- ✗ Not designed for production-scale workloads
- ✗ Limited ecosystem and integrations
Appwrite
Best open-source self-hosted BaaS
- ✓ Docker-based, runs anywhere
- ✓ Full BaaS feature set: auth, DB, storage, functions
- ✗ DevOps overhead for self-hosted deployments
- ✗ Cloud offering still maturing
Convex
Best for real-time TypeScript apps
- ✓ Real-time reactivity out of the box
- ✓ End-to-end TypeScript type safety
- ✗ Opinionated architecture, high switching cost
- ✗ Vendor lock-in with proprietary query model
Neon
Best serverless PostgreSQL
- ✓ Serverless with scale-to-zero
- ✓ Branch-based development workflow
- ✗ PostgreSQL only, no auth or file storage
- ✗ Need to combine with other services for full BaaS
Why Teams Are Migrating Off Firebase
Firebase dominated the 2015-2021 BaaS era. But as apps grew, its cracks showed. After migrating 12+ production apps, here are the recurring reasons we hear:
💸 Unpredictable Billing
Firebase's Blaze plan charges per read/write/delete operation. A single misconfigured listener or a minor traffic spike can generate a multi-thousand dollar bill overnight. Supabase and PocketBase both offer flat monthly pricing.
🔒 NoSQL Lock-In
Firestore's document model forces you to denormalize data and duplicate records for every query pattern. When requirements change, and they always do, restructuring a Firestore schema mid-product is brutal. PostgreSQL handles this with a single ALTER TABLE.
🐌 Cold Start Latency
Firebase Cloud Functions can take 2-8 seconds to cold start. For user-facing APIs this is unacceptable. Supabase Edge Functions and PocketBase hooks run in milliseconds.
🚫 Vendor Lock-In
Firebase is Google's proprietary platform. There's no self-hosted option, no data portability guarantee, and Google has a history of sunsetting products (see: Google Stadia, Google+, Firebase Hosting's free tier changes). Supabase and Appwrite are fully open-source and self-hostable.
⚡ Complex Security Rules
Firestore security rules are a DSL that's easy to misconfigure. Supabase Row-Level Security (RLS) uses standard PostgreSQL policies, understandable, testable, and reviewable.
🔗 Limited No-Code Compatibility
No-code tools like WeWeb, FlutterFlow, and Bubble have native Supabase integrations. Firebase requires custom REST calls or Cloud Functions middleware for most no-code workflows.
Pricing Deep Dive (2026)
Real pricing for real workloads. All figures verified May 2026.
Firebase (Blaze plan)
- • Firestore reads: $0.06 per 100,000 (free: 50K/day)
- • Firestore writes: $0.18 per 100,000 (free: 20K/day)
- • Cloud Functions: $0.40/million invocations + compute
- • Auth: Free up to 10,000 phone auth/month
- ⚠ Real-world cost at 1M active users: $800-$4,000/month (highly variable)
⭐ Supabase
- • Free tier: 500 MB database, 5 GB bandwidth, 1 GB file storage
- • Pro: $25/month, 8 GB DB, 250 GB bandwidth, 100 GB storage
- • Team: $599/month for production SLAs and 15-day backups
- • Auth: Unlimited users on all plans
- ✓ Predictable flat pricing, no per-operation surprises
PocketBase
- • Self-hosted: 100% free, no limits
- • Hosting on Fly.io or Railway: ~$5-$20/month
- • PocketBase Cloud (beta): pricing TBD
- ✓ Cheapest option if you're comfortable with a VPS
Appwrite
- • Cloud Free: 1 project, 75K executions/month
- • Cloud Pro: $15/month, unlimited projects
- • Self-hosted: Free, requires Docker/Kubernetes
Firebase → Supabase Migration Guide
We've completed 12+ production Firebase migrations. Here's the condensed playbook:
Export Firestore data (1-2 days)
Use firebase-admin or the Firestore export feature to dump all collections to JSON. Map your document structure to relational tables, this is where the most architectural decisions live.
Migrate Auth (2-4 days, the hardest part)
Firebase and Supabase use different JWT structures and UID formats. You cannot port Firebase UIDs directly. The recommended approach: export Firebase Auth users, import them into Supabase with a script using the supabase-admin library, and send password reset emails to all users. Social logins (Google, Apple) can be preserved via provider tokens.
Design PostgreSQL schema (1-3 days)
Firestore collections map loosely to Postgres tables, but document nesting usually becomes foreign keys. Use this migration as an opportunity to normalize data properly. Set up Row-Level Security (RLS) policies for each table to replicate Firestore security rules.
Migrate Cloud Functions → Edge Functions (2-5 days)
Firebase Cloud Functions (Node.js) become Supabase Edge Functions (Deno TypeScript) or Postgres database functions. Webhook-triggered logic can often move into Postgres triggers, eliminating the function layer entirely.
Migrate Storage (1-2 days)
Firebase Storage files transfer directly to Supabase Storage buckets. Write a script to iterate Firebase Storage objects and upload them via the Supabase Storage API. Public URLs change format but are easy to update in your database.
Dual-write period + cutover (1-3 days)
Run both backends in parallel for 24-72 hours. Write to both Firebase and Supabase, read from Supabase, monitor for discrepancies. Once confident, flip the read flag, disable Firebase writes, and sunset the Firebase project.

Decision Guide: Which Alternative to Pick
Don't overthink it. Use this as your framework:
Choose Supabase if…
You're building a web app or SaaS, need relational data, want predictable pricing, use no-code tools like WeWeb or FlutterFlow, or are migrating an existing Firebase project. This is our default recommendation for 90% of projects.
Choose PocketBase if…
You're building a prototype or side project, have DevOps skills, want zero monthly cost, or need a single-binary backend that's trivially easy to deploy. Not suitable for >10,000 concurrent users.
Choose Appwrite if…
You need a fully self-hosted BaaS for compliance or data residency reasons (GDPR, HIPAA), are building for mobile-first, or need multi-database support including MongoDB compatibility.
Choose Convex if…
You're building a TypeScript-first real-time app (think collaborative tools, live dashboards) where you want end-to-end type safety and don't mind being locked into Convex's architecture. Not suitable for no-code stacks.
Choose Neon if…
You already have an auth solution (Clerk, Auth0, NextAuth) and just need a serverless PostgreSQL database with branching for development workflows. Combine with Supabase Auth or Clerk for a full backend.
