DBLab enables 🖖 database branching and ⚡️ thin cloning for any Postgres database and empowers DB testing in CI/CD. This optimizes database-related costs while improving time-to-market and software quality. Follow to stay updated.

PostgreSQL database branching

Isolated databases for every AI agent branch. Build, test, and migrate in parallel. Production stays untouched.

Keep your database in sync with your git branches.

Visualize your Neon Postgres branches

The self-hosted Neon alternative — database branching for Postgres on infrastructure you own (AWS, GCP, Azure, or local Docker). Built on DBLab Engine.

Best dev DB for agents — a test database cloned straight from your production. No seeding, no dumps. Real-time Postgres replication of rows and schema, with copy-on-write clones and snapshots.

Branch SQLite like git — copy-on-write forks, checkpoint/rollback/promote, kill-9-durable capture. Stock SQLite files on local disk or S3. Built for AI agents and eval harnesses.

Agentic-first CLI for Neon Postgres - per-project usage, billing, and branch management the dashboard won't show you

⚡ Lighting fast Postgres Branching/Cloning (Work In Progress)

Local PostgreSQL database branching CLI for migrations, schema diff, and isolated development.

The execution environment for AI database agents — give Claude Code, Cursor, or your own agent a disposable branch of your Postgres to run migrations, indexes, and DELETEs against, then throw it away. Production is never touched.

Archived demo of pgoverlay: every PR got a masked copy-on-write clone of prod. The recorded run is PR #1 — a migration that passed locally and failed on real data.

GitHub Action for per-PR Cloudflare preview environments: an isolated Worker, D1, KV & R2 for every pull request — auto-deployed with dev data sync and migrations, torn down on close.

A complete branchable-Postgres stack — storage engine, CSI driver and CloudNativePG — in your own cloud. Branching is copy-on-write in he storage layer, so a fork is instant at any size. Sleep/wake, object cold tier.

Self-hosted Neon: branching CLI + Helm chart for Docker and Kubernetes

Copy-on-write Postgres branches on plain Docker or Kubernetes. Branching a 5 GiB database took 61.9s and copied the whole dataset — until one flag fixed it. Now 1.9s and 33 MiB.

A practical implementation of PostgreSQL 18 logical replication for branch-specific data isolation. Demonstrates bidirectional synchronization between central and branch databases using Docker containers. Perfect for retail businesses or organizations needing distributed data management with automatic synchronization.

Ardent is a database branching platform for Postgres that lets developers and AI coding agents clone any production or development database in seconds into fully isolated, disposable branches.
