Recruiting and ATS software covers a wide spread here: full applicant tracking systems, job boards, application trackers, resume builders, interview tools, and talent matching platforms. For May 2026, ToolVitals data shows a small field of open recruiting tools, with scores ranging from 84 at the top to 22 at the bottom.

This ranking includes open/source-visible tools only and orders them by ToolVitals score first, with GitHub stars used only as a secondary popularity signal. Every listed tool is labeled OSI-approved OSS in the supplied data, with licenses including Apache-2.0, AGPL-3.0, MIT, and GPL-3.0.

Top 3 Highlights

openjobseu ranks first with a ToolVitals score of 84, backed by the highest shipping score in the group at 95 and a health score of 77. Its description is narrower than a general ATS: it is an open-source, compliance-first remote job platform for the EU market. It is OSI-approved OSS under Apache-2.0, has no pricing scope listed, and has 1 GitHub star in the supplied data, so its lead comes from ToolVitals health and shipping signals rather than repository popularity.

Reqcore ranks second with a ToolVitals score of 80 and the strongest general ATS profile near the top of the list. It is described simply as an open-source applicant tracking system, with a health score of 76 and shipping score of 79. It is OSI-approved OSS under AGPL-3.0, has no pricing scope listed, and has 27 GitHub stars, which is the highest star count among the full ATS-style entries in the top three.

Jobsync ranks third with a ToolVitals score of 75. It is more candidate-side than recruiter-side: the supplied description frames it as a self-hosted job application tracker and AI-powered career assistant, with resume review, job matching, task logging, and application analytics. It is OSI-approved OSS under MIT, has no pricing scope listed, and has 0 GitHub stars in the supplied data, so buyers should treat it as a promising but less popularity-validated option.
