RabbitHR as a Greenhouse ATS alternative

Common questions about switching
Yes. Export candidates, jobs and stage timestamps as CSV, map the fields once, and the timeline rebuilds on import.
An afternoon for a normal pipeline. Dry run first, verify counts and attachments, then point the careers page at the new install.
No. Rabbit Agents rank and summarise every applicant, and they show the reasoning behind each score instead of a bare number.
Run one open role on both and decide with data.
The Community Edition is free, so a parallel trial costs you an afternoon.
