OpenCATS vs TriNet: 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 TriNet?
TriNet HR Plus adds a John Hancock 401(k) feed, its second retirement provider link.
TriNet HR Plus now connects to John Hancock through 401(k) Connect, sending deferrals, contributions and employee updates automatically on each payroll date. It follows the Voya connection in September and automated 401(k) match calculations in August. October also brought AI answers and embedded spend, recruiting and leave apps.

OpenCATS

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.
TriNet
5.0HR
TriNet HR Plus adds a John Hancock 401(k) feed, its second retirement provider link.
◆ Current state
TriNet HR Plus now connects to John Hancock through 401(k) Connect, sending deferrals, contributions and employee updates automatically on each payroll date. It follows the Voya connection in September and automated 401(k) match calculations in August. October also brought AI answers and embedded spend, recruiting and leave apps.
◆ Where it's heading
TriNet is building out HR Plus by connecting payroll data to the systems around it: retirement recordkeepers, Salesforce, Slack and broker platforms like Employee Navigator. Retirement integrations are now arriving provider by provider.
◆ Prediction
Expect more 401(k) Connect recordkeepers to be added, following the Voya and John Hancock pattern.
