OpenCATS vs When I Work: at a glance
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 When I Work?
When I Work pushes break compliance, mobile widgets, and richer schedule views — quarterly cadence on the help portal.
When I Work's captured feed mixes help-portal pages with quarterly release-note recaps. The substantive product moves visible: Break Attestation in Q1 2025 (clock-out prompts to record whether breaks were taken, with reasons if not), an iOS Widget surfacing 'Next Shift' to the home screen, broader Scheduling Breaks rollout in Q2 2025 across all plan types, an updated mobile clock-in UI, and an enhanced Schedule Views capability pairing a position view with a new coverage view to see who's working and where gaps exist.

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.
When I Work pushes break compliance, mobile widgets, and richer schedule views — quarterly cadence on the help portal.
◆ Current state
When I Work's captured feed mixes help-portal pages with quarterly release-note recaps. The substantive product moves visible: Break Attestation in Q1 2025 (clock-out prompts to record whether breaks were taken, with reasons if not), an iOS Widget surfacing 'Next Shift' to the home screen, broader Scheduling Breaks rollout in Q2 2025 across all plan types, an updated mobile clock-in UI, and an enhanced Schedule Views capability pairing a position view with a new coverage view to see who's working and where gaps exist.
◆ Where it's heading
Investment is concentrated on operator scheduling depth (position vs. coverage views), compliance hooks for jurisdictions requiring break tracking, and mobile-first usability. The cadence reads as quarterly batched release notes rather than continuous shipping — appropriate for the workforce-scheduling category but slower than SaaS norm.
◆ Prediction
Expect more compliance modules tied to predictive scheduling and fair-workweek rules, additional widget surfaces (Android widget, watchOS), and continued coverage-view evolution as the default manager-centric scheduling lens.
