Instant Postgres branches so coding agents can test safely
Create a 1:1 copy of any Postgres database in under six seconds and keep that speed even at terabyte scale, so agents never wait on test environments.
Every branch is isolated at the compute and storage level, meaning experiments, migrations, and data cleaning can never reach or damage production.
Clones only consume storage for the changes actually made, instead of duplicating the full dataset for every branch.
Branch compute scales with agent workloads and drops to zero when idle, so you never pay to keep idle test databases running.
Ready-made database schemas, sample data and an AI schema designer
Browse ready-made schemas by subject, each with an ER diagram, full column details and an automated design review that calls out missing keys and indexes.
Describe the data you need in plain English, compare generated designs, and download generated rows with working foreign keys in CSV, JSON, SQL, Prisma or Django formats.
Write schema as DBML text and watch the diagram update live, then query generated rows in PostgreSQL or SQLite, inspect the query plan and share the whole thing as one reproducible link.
Deterministically generated datasets with valid foreign keys, available in eight download formats with no account, no attribution and no restrictions.
