Supabase agrees to buy Turso to give each AI agent its own SQLite-compatible database
Supabase raised $150 million and agreed to buy Turso, whose SQLite-compatible engine gives AI agents large numbers of small, isolated databases. The deal rests on Supabase's own count of agent-created databases, and Turso's customers now build on that bet.
The Engineer · Build desk
What happened
- Turso founder Glauber Costa joins Supabase as Head of Agentic Services, along with co-founder Pekka Enberg and the rest of the Turso team.
- Supabase says Turso will keep operating, with a path into the broader Supabase platform.
- The announcement did not state the acquisition price or the timing and conditions for closing.
- The new round comes four months after a $500 million Series F that GIC also led, at a $10 billion pre-money valuation.
Why it matters
- What's now possible capability Supabase can now offer a per-agent database next to the authentication, storage and vector search its Postgres platform already provides.
- Who has to decide decision A team that picks Turso for a new agent project now gets a product whose roadmap will be set inside Supabase.
- Who's exposed exposure Giving every agent its own database means more access settings to configure, and UpGuard's September 25 scan had already found 16,326 Supabase-linked databases exposing readable tables.

Supabase buys Turso so agent databases can start as SQLite and grow into PostgresOne report1 publisher
According to its developers, Turso treats each database as a lightweight file instead of a long-running server process [6]. Supabase says this lets Turso create databases on demand, in Supabase's public cloud or in a customer's own cloud, without a dedicated machine for each one [7]. The cloud service is diskless and keeps the write-ahead log on S3 [15]. The whole design is aimed at cost per database. Turso wrote: "Each agent deserves its own isolated database and the economics have to work at millions of databases." [21]
In my view the rewrite is the hardest engineering in the deal. Turso says SQLite's single-writer limitation held it back for server workloads [14]. The company rewrote the engine from scratch as open source, in Rust, and removed that limit so it supports concurrent writes [6][15].
The demand case comes from Supabase's own numbers. It says agents or AI-driven tools create 70% of new databases on its platform, out of 4 million added each month [2]. If both figures count the same population, agents create about 2.8 million databases a month there [19]. Supabase has not said how it counts users or databases [3]. It also has not said whether its method changed between the nearly 10 million developers it reported in June and the more than 13 million it reports now [13]. That gap is about 3 million developers in four months [20].
I think those figures support a narrow claim. On Supabase, most new databases are now created by software. Both announcements rely only on Supabase's numbers, so they cannot show that agents now set backend database design across the industry.
Turso lists Superhuman, Sauna.ai and Mastra among the teams building agents on it [9]. For those teams the owner changes first. The bigger change is the one Turso promises: "a seamless path to Postgres when an application outgrows them" [8]. RuntimeWire notes that developers still need details on how Turso's product, cloud service and open-source projects will fit alongside Supabase's Postgres-centered platform [18][16].
What to watch
- A closing date and terms for the Turso acquisition, which the announcement left out.
- Any change to Turso cloud pricing or bring-your-own-cloud terms once the product sits inside Supabase.
- The first product from Costa's agentic services group, and whether it runs Turso databases under Supabase authentication.

- [1]
Supabase said on October 2 it had raised $150 million led by GIC and agreed to acquire Turso, adding a database built to provision large numbers of small, isolated databases for AI agents.
- [2]
Supabase says it is adding more than 1 million users and 4 million databases each month, with agents or AI-driven tools creating 70% of new databases.
- [3]
The user and database figures are company-reported, and the announcement does not define how Supabase counts users or databases.
- [4]
The financing arrives four months after Supabase's $500 million Series F and includes employee liquidity.
- [5]
Supabase says Turso will continue operating, with a path into the broader Supabase platform.
- [6]
Turso is an open-source, SQLite-compatible database written in Rust whose architecture treats a database as a lightweight file rather than a long-running server process.
- [7]
Supabase says Turso's architecture can provision databases on demand in its public cloud or in customers' own cloud environments, without assigning a dedicated machine to every database.
- [8]

- [9]
Turso says it is the choice for teams building agents at scale, including Superhuman, Sauna.ai, and Mastra.
- [10]
Glauber Costa joins Supabase as Head of Agentic Services, alongside cofounder Pekka Enberg and the rest of the Turso team.
- [11]
The acquisition price and the timing and conditions for closing were not stated in the announcement.
- [12]
Supabase's June Series F was led by GIC at a $10 billion pre-money valuation.
- [13]
Supabase says more than 13 million developers use its platform; its June Series F post reported nearly 10 million, and Supabase has not explained whether the counting method changed.
- [14]
SQLite was never designed for the demands of modern server workloads and its single-writer limitation has held it back.
- [15]
Turso rewrote SQLite from the ground up as open source, lifted core limitations for server workloads such as concurrent writes, and delivered it through a cloud service built on a diskless, WAL-on-S3 architecture.
- [16]
Supabase's platform is Postgres-centered and includes authentication, storage, edge functions, real-time subscriptions, and vector search.
- [17]
UpGuard's September 25 report identified roughly 300,000 unique domains with Supabase indicators and 16,326 databases exposing readable tables.
- [18]
Developers will need details on how Turso's separate product, cloud service, and open-source projects will fit alongside Supabase after the deal.
- [19]
If the 70% share and the 4 million monthly databases describe the same population, agents or AI tools create about 2.8 million databases a month on Supabase.
- [20]
Supabase's reported developer count rose by about 3 million in roughly four months.
- [21]
Each agent deserves its own isolated database and the economics have to work at millions of databases.
