Turso
Databases
SQLite-lineage database platform for running very large numbers of small per-tenant databases, with an MIT-licensed engine.

The short version
- Each has a real cost: Readyset pricing requires contacting sales team, making cost planning difficult; Turso sQLite allows one writer per database, so a single tenant's write throughput cannot be scaled horizontally and a busy tenant serialises against itself with no sharding option.
- They diverge on capability: Readyset covers Automatic Query Optimization, Turso covers Per-tenant databases.
- Prices and features above were last checked on 30 August 2026.

Readyset
- Reducing database costs for AI workloads with unpredictable query patternsnot Turso
- Improving read performance for frequently accessed data without hardware upgradesnot Turso
- Protecting databases from performance degradation caused by agentic queriesnot Turso
- Scaling read-heavy applications without database scaling costsnot Turso
Turso
- Multi-tenant SaaS where each customer gets their own database for real isolation, per-tenant restore and clean deletionnot Readyset
- Agent or session infrastructure that creates a throwaway database per task and destroys it afterwardsnot Readyset
- Local-first and offline-capable applications where an embedded replica serves reads at file speed and syncs when connectivity returnsnot Readyset
- Embedding a SQLite-compatible engine in a product where the public domain original's closed contribution model is a problemnot Readyset
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Readyset
- Pricing requires contacting sales team, making cost planning difficult
- Specific pricing tiers not disclosed publicly
- Requires cache size estimation for cost calculation
- Limited to read query caching, does not address write performance
Turso
- SQLite allows one writer per database, so a single tenant's write throughput cannot be scaled horizontally and a busy tenant serialises against itself with no sharding option.
- Per-tenant databases mean per-tenant migrations, so every schema change becomes a fan-out job that must be idempotent and resumable, and multi-database schemas, the feature meant to solve this, is deprecated.
- There are no cross-database queries; ATTACH is deprecated on the cloud, so any report or analytic spanning tenants must be assembled in your application or in a separate warehouse you also operate.
- Data Edge, the multi-region edge replication that was Turso's original positioning, is deprecated, so a large share of the tutorials and articles describing Turso as an edge database describe behaviour you can no longer rely on.
- Three engine lineages share the name, SQLite, the libSQL fork and the Rust rewrite, and the Rust engine is still maturing, so SQLite compatibility needs verifying against your specific pragmas, extensions and query patterns; the cloud already restricts journal_mode and busy_timeout and makes user_version read-only.

Questions people ask
- Is Readyset or Turso better?
- Neither clearly leads. Readyset starts at Free and Turso at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Readyset or Turso?
- Readyset starts at Free and Turso at Free.
- Does Readyset or Turso run on more platforms?
- Readyset runs on Cloud, Self-Hosted. Turso runs on Web.
- Can I use Readyset for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Readyset best used for?
- Readyset is most often used for reducing database costs for ai workloads with unpredictable query patterns, improving read performance for frequently accessed data without hardware upgrades, protecting databases from performance degradation caused by agentic queries, scaling read-heavy applications without database scaling costs. Of those, reducing database costs for ai workloads with unpredictable query patterns and improving read performance for frequently accessed data without hardware upgrades are not what Turso is typically brought in for.
- What can Readyset do that Turso cannot?
- Readyset covers Automatic Query Optimization, SQL-Level Caching, Live Incremental Updates, Zero-Touch Integration. Turso covers Per-tenant databases, MIT licence, Embedded replicas, SQLite compatibility.
Answered from the vendors’ own pages
Readyset: Do I need to change my application code?
No, Readyset integrates transparently through query interception with zero code changes or schema modifications required.
SourceTurso: Is Turso just hosted SQLite?
Not exactly. It hosts databases built on the SQLite lineage: libSQL, an MIT fork of SQLite, and Turso Database, a newer Rust rewrite. The platform adds branching, backups, an HTTP API and programmatic database creation.
Readyset: Is there a free trial?
Yes, Readyset offers a free 7-day trial that lets you test different cache sizes before committing to a paid plan.
SourceTurso: Can I really run a million databases?
That is the design goal and the platform API exists to make provisioning and deletion programmatic. The practical constraints are the ones that come with it: migrations fan out, and nothing can query across databases.
Readyset: How does Readyset pricing work?
Readyset is available as a monthly or annual subscription charged based on the size of cache you need. Contact [email protected] for specific pricing.
SourceTurso: How do embedded replicas handle read-after-write?
Reads come from the local replica and writes go to the primary, so a read immediately after a write can return stale data unless you wait for a sync. Application code has to account for that rather than assume it.
Turso: What licence is it under?
libSQL and Turso Database are both MIT. Turso Cloud is a commercial managed service built on them, so the engine is genuinely open even though the platform is not.
Turso: Is Turso still an edge database?
No. Data Edge, the multi-region edge replication feature, is deprecated. The current positioning is per-tenant and embedded databases, and older material describing edge replication is out of date.
