About Proletaria

Proletaria is a labor-market analytics terminal. It publishes daily data about companies, skills, and open roles, built from the job listings the employers it tracks post publicly. Nothing here is estimated or backfilled from a public dataset — every listing is tied to the employer’s own posting URL.

Data quality

Each employer’s daily update is checked against its own recent history before it can change any count. An update that fails those checks is held back for that day rather than allowed to mark real postings as “removed” — see how the quality gates work.

Employer attribution

Every listing links back to the employer’s own posting. Proletaria does not host applications, collect candidate data, or represent itself as the hiring employer — it is an independent read on public postings, cited the way the data-use terms on the API page describe.
