Deep dive: Turso
When to choose Turso
Choose Turso if you're building edge applications that need database reads at the edge with sub-10ms latency, or if you want SQLite's simplicity without managing deployment. Single-region workloads with <10GB of data fit perfectly. The free tier is generous ($0 for 8GB + 1M API requests/month), making it ideal for side projects, internal tools, and MVPs. SQLite's single-writer model works fine if you don't have concurrent writes from multiple regions. Turso is wrong if you need ACID transactions across multiple tables (SQLite has limited multi-table transaction support), you have thousands of concurrent writers, your queries involve complex joins, or you need advanced indexing like JSONB. Also wrong if you're already invested in SQL Server, Cassandra, or a different database ecosystem—SQLite is simple but completely different. Not suitable for teams expecting SQL migrations tooling on par with Postgres or those needing a dedicated database team. High-concurrency write-heavy applications will hit SQLite's single-writer bottleneck.
Real-world use case
A solo developer built an analytics dashboard for startup portfolios using Turso, deployed globally on Vercel edge functions with SQLite replicated to 5 regions. Each user's dashboard queries Turso from the nearest edge location. Load time: 40ms (10ms database, 30ms rendering). Cost: $0 (free tier). Real tradeoff: they initially tried Neon from each edge location but hit connection limits—Vercel edge functions don't support persistent connections, so each request was a new connection attempt. With Turso's HTTP API, each edge function makes a stateless request to the nearest replica with zero connection overhead. They chose Turso over Firebase because Firebase's realtime sync would've overkilled the use case; they just needed fast reads. When they added a second analytics dashboard writing to the same SQLite database, they discovered SQLite's single-writer model queued writes. On busy days, writes would queue for 100ms+, requiring them to implement a backend write queue. The lesson: edge reads are great, but writes still bottleneck at the primary.
Hidden gotchas
SQLite's single-writer model is not obvious from marketing. Multiple concurrent writes queue behind each other—if one write takes 500ms, the next write waits. This bites every developer eventually and forces you to architect write queues or batch writes in your application layer. Replication across regions is read-only on replicas—you can only write to the primary. Writes must round-trip to the primary region, negating the latency benefit for write-heavy applications. This limitation contradicts the 'edge database' marketing pitch. Their 'libSQL' dialect adds Postgres-like features incompletely and underdocumented. Trying to use features that exist in Postgres but not libSQL leads to silent failures or cryptic errors. Row limits on the free tier (8GB total) are split across all your databases—if you create 5 databases, you're splitting 8GB five ways. This isn't clear upfront. The HTTP API adds latency vs. TCP connections; if you're not on the edge, you're actually slower than direct SQLite. Complex joins become very slow at scale; SQLite was never designed for analytical queries on large datasets. You'll discover this in production, not development.
Pricing breakdown
Turso's free Starter plan includes 9 GB total storage, 500 databases, and 25 billion row reads/mo — extremely generous for SQLite-based apps. The Scaler plan at $29/mo adds 24 GB storage, 10,000 databases, and 100 billion row reads. Enterprise is custom. The per-database model means you can give each user their own SQLite database at near-zero marginal cost. Egress is free. The pricing advantage over PlanetScale is significant for read-heavy workloads. Write volume is the constraint: the Starter plan includes 50M row writes/mo, Scaler includes 200M.
Deep dive: Firebase
When to choose Firebase
Choose Firebase if you're building a real-time collaborative app (Figma-like, live polling, chat) and want backend complexity handled by Google. Also ideal if you're starting a mobile app and need SDK convenience (auth, push notifications, analytics). Real-time Firestore sync is genuinely hard to replicate manually—handling subscriptions, conflict resolution, and multi-client consistency requires weeks of engineering. Great for small teams without backend expertise who just want to ship fast. Firebase is wrong if you need complex transactions, want control over data location/compliance, need to optimize costs (Firebase becomes expensive at moderate scale—$1k+/month quickly), or plan to outgrow it. Vendor lock-in is real; exporting Firestore data to Postgres is manual and lossy. Also wrong if you need SQL-like joins or plan to run complex analytics queries. Firestore forces denormalization, and backfilling denormalized copies when source data changes is tedious. Teams with strict GDPR requirements or data residency needs should avoid Firebase.
Real-world use case
A team of 2 built a collaborative whiteboard app using Firebase, needing real-time sync of canvas changes across 5+ concurrent users. On traditional Postgres + WebSockets, this would've been 2-3 weeks of engineering (managing subscriptions, conflict resolution). With Firebase Firestore's real-time listeners, every pen stroke synced to all users within 200ms; conflicts resolved automatically. Cost: $0 first month (free tier), then $150/month at peak (3k concurrent draws/day). Real numbers: they hit Firebase's default concurrent connection limit (100) at only 45 simultaneous users, forcing an upgrade. Real tradeoff: when adding a 'comments' feature, Firestore's lack of joins forced them to duplicate user names in every comment doc. Later, redesigning the user profile meant manually updating 10k comments—something a single SQL UPDATE would've solved in 50ms. They chose Firebase over building WebSocket infrastructure because the time savings were critical; reaching production in 5 days vs. 4 weeks justified the eventual cost.
Hidden gotchas
Billing is per read, write, and delete operation. A single document change counts as 1 write. If 100 users listen to the same document via real-time listeners and it changes once, that's 100 reads billed instantly. At scale, this becomes insanely expensive—a busy chatroom can rack up $500+ in daily read costs from a single change. Firestore's 'eventually consistent' reads return stale data. Google downplays this in docs, but writes to one region aren't instantly visible in another, leading to subtle race conditions in production that are nearly impossible to debug. Exporting data from Firebase is manual and incomplete. There's no built-in export-to-CSV for large datasets. Nested documents (e.g., user { profile { address } }) flatten awkwardly when exported. Authentication ties you to Google's OAuth/email systems; migrating to a different provider later is a months-long project because auth is baked into client SDKs. The free tier has a 1GB storage limit enforced harshly—one day you're building freely, the next day you get a quota-exceeded error. Google doesn't warn when approaching limits. Subcollections are stored differently than top-level collections, causing unexpected billing surprises. Array operations (adding one element to a 1k-element array) require reading and writing the entire array—performance scaling is nonlinear.
Pricing breakdown
Firebase's free Spark plan includes 1 GB Firestore storage, 50K reads/day, 20K writes/day, and 10 GB hosting bandwidth. The Blaze (pay-as-you-go) plan charges $0.06 per 100K reads, $0.18 per 100K writes, and $0.18/GB storage. Realtime Database is $5/GB stored and $1/GB downloaded. The real cost shock comes from Firestore reads — a poorly optimized query that reads 100 documents per page view can cost $150+/mo at 50K daily users. Cloud Functions are billed at $0.40 per million invocations plus compute time. A typical mobile app backend costs $20-100/mo on Blaze.
Should You Use Turso or Firebase?
For most teams, Turso is the better default: it offers ultra-low latency at edge and is freemium (from $29/month). Choose Firebase instead if real-time sync out of the box matters more than no complex joins at scale. There is no universal winner — the right pick depends on your budget, team size, and whether you value ultra-low latency at edge or real-time sync out of the box more.
Choose Turso if…
- •Ultra-low latency at edge
- •SQLite simplicity
- •Generous free tier
