Show HN: EterDB, a Postgres fork that makes it easy to recover from incidents

3•fdeth•1h ago
Hey everyone, a few months ago, after recovering from a Clade-generated bug, I was thinking to myself “wouldn’t it be nice if prod DB writes were easy to roll back”. I’ve put something together: it’s a two-container deploy plus a CLI tool. It’s far from being production ready, so please be gentle. All feedback welcome!

The nitty gritty: https://eterdb.com/tech
