Introduction

Database Lab Engine, from Postgres.ai, provides thin clones and branches of PostgreSQL databases for development and testing. It works with any PostgreSQL, including managed services such as AWS RDS, GCP Cloud SQL, Supabase and Timescale; for managed services it runs on a separate VM and refreshes data regularly.

Thin cloning means each developer, CI job or test can get its own full-size copy quickly without duplicating storage, so migrations and queries can be tested against realistic data. It offers a CLI, API and UI.

In the quality loop DBLab enables realistic database tests in CI.

The source code is at postgres-ai/database-lab-engine on GitHub under the Apache-2.0 licence, with about 2,800 stars; the most recent commit was on 11 November 2026.

Features

1. Thin clones: Fast full-size copies.
2. Branching: Git-like database branches.
3. Managed PG support: RDS, Cloud SQL and others.
4. CLI and API: Automate in CI.
5. UI: Manage clones.
6. Auto-refresh: Keep data current.

Pros

1. Realistic tests: Production-sized data quickly.
2. Free to use: Open source under the Apache-2.0 licence, so the core tool costs nothing to use.
3. Actively maintained: The repository had commits as recent as 11 November 2026.

Cons

1. Data privacy: Copies need masking.
2. Infrastructure: Needs a host with storage.
3. PostgreSQL only: No other databases.

Usage and Links (Example)

1. Install DBLab on a VM near your database and configure the data source.
2. Let it provision the initial copy and snapshots.
3. In CI, request a clone through the CLI or API, run migrations and tests against it, then destroy the clone.
