// SUPPORTED ATS
The ATS platforms we fill reliably.
Open Applier supports the four ATS platforms used by most mid-market and enterprise employers. We only list the ones we fill reliably — not a longer list padded with “supported in theory” entries.
Supported ATS platforms
Workday
Workday is the most time-consuming ATS to fill by hand. Open Applier reads your saved profile and completes every required field across the multi-step flow so you can review once and submit.
Greenhouse
Greenhouse is fast to apply to individually — and brutal at scale when every board asks for the same ten fields. Open Applier fills your Greenhouse applications from one saved profile and tailors the resume per job.
Lever
Lever's single-page apply flow is the cleanest ATS to automate — and the one where AI-tailored cover letters show the clearest lift. Open Applier handles the fill and tailors the resume + cover letter per role.
Ashby
Ashby's modern forms are designed to feel fast — and still ask for the same twelve fields every time. Open Applier fills your Ashby applications from one saved profile and tailors the resume per role.
