Firebase vs Turso
Firebase and Turso both answer the same question: where does your data live? Google's mobile-first backend with a document store, realtime sync, offline support and push notifications in one bundle. SQLite as a hosted service, replicated to the edge, with the option of one small database per customer. Firebase covers more of the ecosystem, so it survives a change of framework; Turso is the better fit while you stay where it is strongest.
Verdict
Firebase covers more of the ecosystem, so it survives a change of framework; Turso is the better fit while you stay where it is strongest.
Pick Firebase if
- ✓Offline persistence and conflict handling on mobile are genuinely solved problems here.
- ✓Push notifications, crash reporting and analytics come from the same console.
- ✓Realtime listeners make collaborative and chat-style features straightforward.
Pick Turso if
- ✓Database per tenant is cheap, which makes hard isolation between customers practical.
- ✓Edge replicas put reads physically close to the user.
- ✓SQLite semantics are simple and identical to what you run in tests locally.
| Comparison | Firebase | Turso |
|---|---|---|
| Pricing shape | Free Spark tier, then pay as you go priced mainly on document reads, writes and stored data. | Generous free tier, then usage-based on rows read and written plus stored data. |
| Frameworks | Next.js, React Native, Expo, Flutter | Next.js, SvelteKit, Nuxt |
| In one line | Google's mobile-first backend with a document store, realtime sync, offline support and push notifications in one bundle. | SQLite as a hosted service, replicated to the edge, with the option of one small database per customer. |

Firebase
Strengths
- ✓Offline persistence and conflict handling on mobile are genuinely solved problems here.
- ✓Push notifications, crash reporting and analytics come from the same console.
- ✓Realtime listeners make collaborative and chat-style features straightforward.
- ✓Very long track record, so mobile developers already know the patterns.
Tradeoffs
- ✗Document model punishes relational data, pushing you toward heavy denormalization.
- ✗Billing counts document reads, so a careless listener can cost real money.
- ✗Security rules are a separate language with their own testing story.
- ✗Deep Google Cloud coupling makes leaving a full backend rewrite.
Turso
Strengths
- ✓Database per tenant is cheap, which makes hard isolation between customers practical.
- ✓Edge replicas put reads physically close to the user.
- ✓SQLite semantics are simple and identical to what you run in tests locally.
- ✓Embedded replicas let a server read locally and sync writes upstream.
Tradeoffs
- ✗SQLite has one writer, so write-heavy workloads hit a ceiling by design.
- ✗Fewer data types and functions than Postgres, so some modelling gets manual.
- ✗Managing thousands of small databases becomes its own operational surface.
- ✗Replication lag means a read after write can return stale data.
Frequently asked questions
Is Firebase or Turso better?
Neither is better in the abstract. Firebase covers more of the ecosystem, so it survives a change of framework; Turso is the better fit while you stay where it is strongest. Pick the one whose downside you can absorb, because both upsides are real.
What is the main drawback of Firebase?
Document model punishes relational data, pushing you toward heavy denormalization. Billing counts document reads, so a careless listener can cost real money.
What is the main drawback of Turso?
SQLite has one writer, so write-heavy workloads hit a ceiling by design. Fewer data types and functions than Postgres, so some modelling gets manual.
Can you switch from one to the other later?
Usually, at a cost that grows with how much of your product leans on the database layer. Keep the integration behind a thin module of your own and the migration stays a weekend rather than a quarter.
