A serverless PostgreSQL platform that separates storage from compute — enabling instant database branching, autoscaling to zero when idle, and per-second billing with full Postgres compatibility.
Why it is useful
Solves the cold-start and cost problem for serverless Postgres: it scales to zero when idle (no charges) and resumes in milliseconds. Database branching creates isolated copies of production data in seconds, which makes development and testing workflows dramatically safer. The free tier includes branching, enough storage, and compute for real projects without a credit card.
