Launch HN: Ardent (YC P26) – Postgres sandboxes in seconds with zero migration

Create copies of any Postgres database in under 6 seconds so coding agents can verify their code works in prod

Ardent CLI

Validate code before it reaches production

Stop breakages

Validate code before it reaches production

Let Coding agents test their database code on a 1:1 copy of your production postgres

Book a Demo

Test with zero risk to production

Zero blast radius

Test with zero risk to production

Each clone is isolated at both the compute and storage level. Clones never impact production. Ever

Book a Demo

Cloning that never slows down even at terabyte scale

Speed at scale

Cloning that never slows down even at terabyte scale

Clones load in 6s, scale to 0, autoscale compute and do not duplicate storage. Zero management needed

What the best say

Trusted by the best in Data

I think AI will disrupt data engineering in a significant way. I'm investing in Ardent to accelerate that disruption!
