How Much Does It Cost to Migrate from Firebase to Supabase?
Transparent, fixed pricing for your Firebase → Supabase migration. No hidden fees, no hourly billing surprises.
Migration cost summary
A medium-effort Firebase → Supabase migration typically costs €5,000–€14,000 and takes 2–4 weeks from kickoff to go-live. The final price depends on four primary factors explained below. App Studio provides a fixed quote — not an estimate — after a free 30-minute scoping call.
What affects the Firebase → Supabase migration cost?
Data volume & complexity
Migrating a Firebase app with 10,000 rows costs less than one with 500,000. Complex relational data models, custom field types, or binary storage require extra mapping and validation work.
Number of integrations
Each third-party connection — Stripe, Twilio, OAuth providers, CRMs, custom APIs — must be re-wired and tested in Supabase. Apps with 3+ integrations typically land in the higher end of the range.
UI rebuild fidelity
A pixel-perfect UI rebuild with custom components and complex responsive layouts takes longer than migrating to a standard template. If you are using this migration to modernise your design, budget accordingly.
Business logic density
Conditional workflows, custom permissions, multi-step automations, and edge-case handling in Firebase all need to be re-implemented in Supabase. The more rules, the more time.
Cost breakdown by migration phase
How the budget is typically distributed across a Firebase → Supabase migration project.
| Phase | % of budget | Typical cost range | Deliverable |
|---|---|---|---|
| Audit & discovery | 15% | €750 – €2,100 | Feature map, migration plan, risk register |
| Rebuild & integrate | 60% | €3,000 – €8,400 | Working Supabase app in staging |
| QA & testing | 15% | €750 – €2,100 | Regression report, performance benchmarks |
| Launch & handover | 10% | €500 – €1,400 | Live on Supabase, docs & credentials delivered |
No-code migration vs. custom code rebuild
Many teams consider rebuilding in Supabase from scratch with a traditional developer. Here is how the costs compare:
| App Studio (no-code) | Traditional dev team | |
|---|---|---|
| Cost | €5,000–€14,000 | €30,000–€150,000+ |
| Timeline | 2–4 weeks | 4–12 months |
| Iteration speed | Days | Weeks |
| Maintenance | Low (no-code tooling) | High (custom codebase) |
| Risk | Low (fixed price) | High (time & materials) |
Firebase → Supabase migration cost — FAQ
How much does a Firebase to Supabase migration cost?
A typical Firebase to Supabase migration costs between €5,000 and €14,000, depending on app complexity, number of integrations, and data volume. App Studio provides a fixed-price quote after a free 30-minute scoping call.
What is included in the migration price?
The fixed price covers the full audit, data export and import, UI rebuild in Supabase, integration re-wiring, QA testing, go-live support, and handover documentation. No hourly surprises.
Why does Firebase migration effort vary?
The main variables are: number of database tables and relationships, number of third-party integrations, complexity of business logic, and whether you want a UI refresh or a like-for-like rebuild. We assess all of these in the scoping call.
Can the price go above the high estimate?
Only if scope increases beyond what was agreed at kickoff. We price fixed-scope: what is quoted is what you pay. If new requirements emerge mid-project, we scope and price them separately.
