Supabase acquires Turso and releases new Postgres tools

Supabase announced the acquisition of Turso, a SQLite-based database provider, to address the challenge of scaling out to billions of databases per month. The company currently launches approximately 5 million databases monthly but anticipates needing to reach billions to support agentic workloads. Turso’s architecture builds Multi-Version Concurrency Control for SQLite, enabling multiple writers, and leverages object storage innovations like S3 Express for durable, low-latency writes. Supabase will retain the Turso brand for SQLite focus and introduce a new lightweight instance type called Supabase Spark, compatible with existing libraries. The company also announced a new investment partnership with Capital G, an Alphabet-backed firm, to facilitate a multi-cloud strategy including GCP access. Simultaneously, Supabase released Multigrass, a ground-up rewrite of a Postgres operator designed to provide sharding and high availability without code changes. Testing revealed that existing Postgres operators could lose data under certain conditions, whereas Multigrass survived 1,000 sequential failovers without data loss. Supabase also launched OrionDB in full beta, a drop-in replacement for the Postgres heap storage engine that runs 1.5 to 2 times faster and eliminates the need for background vacuum tasks. The technology is licensed under Apache 2, with Supabase having acquired the underlying patents. Design partners for these initiatives include Booz Allen, Postman, and Perplexity. Additionally, Supabase announced Supabase Compute, a serverless product that removes the two-second limit of its previous Edge Functions, allowing for long-running workloads including running AI agents. The platform supports full containers and languages like Rust and Python. Supabase also introduced pg-donta, a library that enables declarative schema management, replacing the traditional migration-file approach with a file-based representation of the database state.
