Why OpenATS
OpenATS vs. Greenhouse: structured hiring without a closed foundation
OpenATS brings structured interviews, scorecards, job boards, pipelines, offers, reporting, and candidate history into an ATS your team can actually own. Greenhouse is established and has a broad partner ecosystem, but its platform remains vendor-hosted and proprietary. OpenATS is the better choice when you want the structured-hiring discipline Greenhouse is built around without making a closed product the permanent foundation of recruiting operations.
