What is OpenCATS?
OpenCATS ships PHP 8.4/8.5 compatibility, utf8mb4 migration, and country support in its most significant release in years.
OpenCATS delivered two major releases in quick succession: v0.11.0 brought the long-deferred PHP 8 compatibility overhaul, utf8mb4 database migration, full country support across candidates/contacts/companies/job orders, CAPTCHA for career portal applications, and the replacement of the old Google ZIP lookup with OpenStreetMap Nominatim. v0.11.1 followed with a focused security hardening pass — SQL input validation, CSV import field mapping, mass-import file handling — plus Career Portal fixes and expanded contributor documentation.
What is Teamtailor?
Teamtailor adds multi-value and country filters to requisitions after a week of division settings.
Teamtailor's AI layer is extensive: MCP access for external agents, Co-pilot chasing missing candidate info, prompt-defined Smart action triggers and Meeting insights across analysed interviews. Recent releases are structural: compensation types beyond salary, locations scoped per division, a renameable 'Main company' label, and now requisition filters that take several values, a Country filter, and page-aware bulk selection.

OpenCATS ships PHP 8.4/8.5 compatibility, utf8mb4 migration, and country support in its most significant release in years.
◆ Current state
OpenCATS delivered two major releases in quick succession: v0.11.0 brought the long-deferred PHP 8 compatibility overhaul, utf8mb4 database migration, full country support across candidates/contacts/companies/job orders, CAPTCHA for career portal applications, and the replacement of the old Google ZIP lookup with OpenStreetMap Nominatim. v0.11.1 followed with a focused security hardening pass — SQL input validation, CSV import field mapping, mass-import file handling — plus Career Portal fixes and expanded contributor documentation.
◆ Where it's heading
OpenCATS is undergoing a systematic modernization of its technical foundation: InnoDB migration (v0.10.0), PHP 8 + utf8mb4 (v0.11.0), security hardening (v0.11.1). The project is not adding net-new capability so much as making what exists maintainable and secure enough to run in modern environments. The expanded contributing documentation and automated legacy database testing signal that maintainers are investing in the contributor pipeline.
◆ Prediction
After the modernization sprint, the next likely move is a modern email/rich text editor replacement (CKEditor 4 was pinned at the final open-source release as a placeholder) and further security audit work on endpoints that haven't been touched since the v0.9 era.
Teamtailor adds multi-value and country filters to requisitions after a week of division settings.
◆ Current state
Teamtailor's AI layer is extensive: MCP access for external agents, Co-pilot chasing missing candidate info, prompt-defined Smart action triggers and Meeting insights across analysed interviews. Recent releases are structural: compensation types beyond salary, locations scoped per division, a renameable 'Main company' label, and now requisition filters that take several values, a Country filter, and page-aware bulk selection.
◆ Where it's heading
Two tracks run in parallel. One turns Co-pilot data into automation and job-level analytics; the other adds configuration and admin depth for multi-division, multi-country employers. Requisition filtering by country and multiple recruiters or departments fits the same up-market push toward larger hiring teams.
◆ Prediction
Expect further division- and country-level scoping beyond locations and requisitions, such as templates or permissions, and Meeting insights-style aggregation for other Co-pilot outputs.
