What is OpenCATS?
OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX
OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.
What is Teamtailor?
Teamtailor readies its ATS for AI on both sides — agent-discoverable career sites, deeper Co-pilot.
Teamtailor is building around two threads: an AI Co-pilot (custom report charts, saved prompts, three-state screening) and candidate-experience plumbing (WhatsApp messaging, candidate Timeline, skills-library merge). The standout is a quieter move — making every career site discoverable by AI agents via open agentic-web standards. The work spans channel reach, data hygiene, and AI assistance.

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX
◆ Current state
OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.
◆ Where it's heading
The pattern is a community project moving in slow, security-conscious increments: authenticated attachments and earlier XSS/cookie hardening show steady attention to securing an aging codebase. v0.10.0 suggests renewed maintenance momentum rather than a feature pivot.
◆ Prediction
Expect continued infrequent releases focused on security hardening and PHP-version compatibility. A jump in cadence would be the signal to watch for renewed active development.

◆ Current state
Teamtailor is building around two threads: an AI Co-pilot (custom report charts, saved prompts, three-state screening) and candidate-experience plumbing (WhatsApp messaging, candidate Timeline, skills-library merge). The standout is a quieter move — making every career site discoverable by AI agents via open agentic-web standards. The work spans channel reach, data hygiene, and AI assistance.
◆ Where it's heading
Teamtailor is preparing its ATS for a hiring funnel where both recruiters and candidates lean on AI: Co-pilot takes on more evaluation and reporting work, while career sites are being made legible to candidate-side AI agents. Alongside, it is widening communication channels (now WhatsApp) and tightening candidate data (Timeline, skill merges). The direction is an AI-mediated recruiting workflow on both sides of the table.
◆ Prediction
Expect deeper Co-pilot capability — more evaluation and reporting automation — and further investment in agent-discoverability now that the career-site standards are live. The WhatsApp launch suggests more unified-inbox channels may follow.
