DBLab Engine
⚡ Blazing-fast Postgres cloning and branching 🐘
🛠️ Build powerful dev/test environments.
🔃 Cover 100% of DB migrations with CI tests.
💡 Quickly verify ChatGPT ideas to get rid of hallucinations.
Available for any PostgreSQL, including self-managed and managed* like AWS RDS, GCP CloudSQL, Supabase, Timescale.
Can be installed and used anywhere: all clouds and on-premises.
*For managed PostgreSQL cloud services like AWS RDS or Heroku, direct physical connection and PGDATA access aren't possible. In these cases, DBLab should run on a separate VM within the same region. It will routinely auto-refresh its data, effectively acting as a database-as-a-service solution. This setup then offers thin database branching ideal for development and testing.
Why DBLab?
- Build dev/QA/staging environments using full-scale, production-like databases.
- Provide temporary full-size database clones for SQL query analysis and optimization (see also: SQL optimization chatbot Joe).
- Automatically test database changes in CI/CD pipelines, minimizing risks of production incidents.
- Rapidly validate ChatGPT or other LLM concepts, check for hallucinations, and iterate towards effective solutions.
For example, cloning a 1 TiB PostgreSQL database takes just about 10 seconds. On a single machine, you can have dozens of independent clones running simultaneously, supporting extensive development and testing activities without any added hardware costs.

How it works
Thin cloning is fast because it is based on Copy-on-Write (CoW). DBLab employs two technologies for enabling thin cloning: ZFS (default) and LVM.
Using ZFS, DBLab routinely takes new snapshots of the data directory, managing a collection of them and removing old or unused ones. When requesting a fresh clone, users have the option to select their preferred snapshot.
