An honest security analysis of Turso for developers considering it for their projects.
Turso is safe for edge SQLite with unique embedded replica architecture. Unlike Neon/PlanetScale (centralized), Turso replicates to edge locations and even INTO your app. Auth tokens control access. Main concern: embedded replicas in client apps expose read-only data.
Turso's edge SQLite architecture is innovative but requires understanding the security model. Embedded replicas in client apps expose data (read-only) - this is by design for offline-first apps. Use read-only tokens for clients, keep full-access tokens server-side. No RLS means application-level authorization.
Understanding Turso security in the context of broader industry trends and research.

“Vibe coding your way to a production codebase is clearly risky. Most of the work we do as software engineers involves evolving existing systems, where the quality and understandability of the underlying code is crucial.”
“The problem with AI-generated code isn't that it doesn't work - it's that it works just well enough to ship, but contains subtle security flaws that are hard to spot.”
Embedded replicas sync a read-only copy of your database INTO your application (mobile app, Electron, etc.). This enables offline access and fast reads. Security implication: data in embedded replicas is accessible to anyone with the app. Use for non-sensitive data or encrypt at application level.
No. Turso uses libSQL (SQLite fork) which doesn't have RLS. Unlike Supabase/Neon (PostgreSQL with RLS), you must implement access control in your application layer. This is a fundamental SQLite limitation, not Turso-specific.
Turso uses JWT tokens with configurable permissions. Create read-only tokens for client apps and embedded replicas. Keep full-access tokens server-side only. Tokens can be scoped to specific databases. Rotate tokens if exposed.
For server-side access with full-access tokens, yes. For embedded replicas in client apps, be careful - the data is readable. Encrypt sensitive fields at application level before storing, or keep sensitive data in server-only databases. Turso is ideal for edge caching of non-sensitive data.
