Most "company hiring signal" tools scrape LinkedIn. company-hiring-tracker does something simpler: most companies that use Greenhouse or Lever for hiring expose their open roles through a public, unauthenticated API on their own job board. No login, no proxy, no headless browser, just a fetch.
Give it a company's ATS (Greenhouse or Lever) and board slug, and it returns each open role: title, location, department, and posting date, as clean JSON.
{ "title": "Senior Backend Engineer", "location": "Remote", "department": "Engineering", "postedAt": "2026-09-10" }
Priced per board queried, not per job returned, so checking a company with 40 open roles costs the same as checking one with 2.
