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

I mean, they said "read-only" ...

Hey, I put on my pants the same way you do: by having my staff hold them up while I jump into them.

This isn't quite as risky as it seems. All of them have a TOS that says if you pay them enough money they won't train on your data. But you're right that there are probably a lot of people who aren't on those plans sharing private data.

But also, for smaller companies, this isn't an issue since they don't have SOC2 and the other compliance needs yet. So it's probably a sane starting place for Ardent at this time. Most small startups let everyone in the company access the full database anyway.

> Perhaps a data policy should be required to be in place before a branch can be cloned... The default configuration giving the LLM full prod data access by default, is a bad standard to set, I think.

Or at least an easy way to copy it from the database you're branching from.

It's not uncommon (Hex.ai, etc all do this, as do developers, MCP tools, etc). One thing we do at Ardent is enable obfuscated read replicas. We can strip PII in the replicas, so your agents are operating on very realistic (but not sensitive) data. Moreover, they can do so in a way that doesn't impact your production database and is fast enough to wire into your CI/CD processes.

Jeremy is correct, though. The main risk/concern is primarily agents with write access. There are two high profile instances in the last year of agents dropping production databases (even when, in one case, after being given explicit instructions to never do such a thing). While read-replicas of a primary DB solve the "agents can't destroy things" problem, they don't solve things like testing schema migrations (in particular) or updates to the data.

I’m very confused as to the target market here
