Using this for testing... it feels like a sweet spot between in-memory SQLite and spinning up a full Postgres instance. I'd been looking for this for a while and I'm pretty happy with the faster tests. And so far no blockers from its limitations.
I'm using conductor.build and running both Claude Code and Codex. It's taken 95% of my workflow and I'm loving it (I'm not affiliated with them at all, genuinely enjoying it and hoping it succeed)
