Resume ATS Checker is built and maintained by Sam Lui, a developer based in San Francisco. There's no team, no outside funding, and no premium tier hiding behind the free version — just a resume audit tool built to solve one specific frustration: expensive resume platforms that show you a locked score and ask for payment before telling you what's actually wrong.
The tool scans resumes against 20+ factors modeled on how real Applicant Tracking Systems parse, rank, and filter applications — formatting safety, keyword alignment, structure, grammar, and more — and shows the full result on the page, not behind a paywall or a forced download.
