## What it is
DBLab Engine is an open-source platform that provides instant, full-size thin clones and branching of PostgreSQL databases using ZFS copy-on-write, running on your own infrastructure. It enables fast dev/test/staging environments, CI/CD testing of database migrations, and SQL optimization against production-like data.

## Use cases
- create instant full-size clones of production postgres for testing
- test database migrations in CI/CD pipelines
- set up database branching for preview environments
- optimize slow SQL queries against production-like data
- provide dev and QA teams with isolated database copies cheaply
- mask sensitive data in non-production database clones
- verify AI-generated SQL ideas on real data

## When to choose
- you need many full-size Postgres clones without proportional storage costs
- you want to cover database migrations with CI tests on real data
- you use managed Postgres (RDS, Cloud SQL, Supabase) and need fast clones
- you want everything self-hosted within your own infrastructure

## When to avoid
- you don't run PostgreSQL or a Postgres-compatible database
- you cannot provision a Linux server with a ZFS volume and ~30% extra disk
- you only need small ephemeral test fixtures rather than full-size production data
- you want a fully managed SaaS without operating any infrastructure
