Supabase Acquires Turso to Build Databases for AI Agents

Supabase, best known for its PostgreSQL platform, has announced the acquisition of Turso, the project that rebuilt SQLite in Rust. According to co-founder and CEO Paul Copplestone, the deal is driven by a new development pattern: AI agents are generating an immense amount of software, and with it millions of databases powering prototypes, dashboards and apps.

Databases for agents

Supabase says it already launches over a million databases per week. The company believes that as agents write ever more code, database demand will outpace the world's current capacity. The conclusion: infrastructure is needed that fits exactly this way of building.

The idea is simple. An agent should be able to create a database as easily as a file, and worry about its cost just as little. Small workloads shouldn't require provisioning a dedicated machine every time. Databases should be cheap to create, available on demand, and have a clear path to production when needed.

This is where the two databases split roles. SQLite suits small, on-demand workloads; PostgreSQL is what you want as an application scales. Supabase wants developers to have the same experience from prototyping all the way to production.

What Turso brings

Turso has built an architecture for precisely this scenario. Its SQLite engine is rewritten in Rust, and its cloud platform is designed so that a single server can manage millions of databases, loading them on demand and suspending them when idle. That makes it possible to provision a dedicated database per agent on demand, whether in Turso Cloud or in customers' own clouds. Companies cited as using the approach include Superhuman, Sauna.ai, CTO.new and Mastra.

Open source

For existing users, Supabase stresses, nothing changes: Supabase will keep building around PostgreSQL, Turso will keep working on SQLite, and together they will create something new. Both teams share a commitment to open source, a focus on developer experience, and an appetite for hard infrastructure problems.

Glauber Costa and Pekka Enberg are joining Supabase along with the rest of the Turso team, with Costa leading the agentic infrastructure effort. Copplestone sums up the company's mission briefly: to store the world's data — and agents, he says, are going to create a lot more of it.
