A side-by-side editorial comparison of Miter and OpenCATS — release velocity, themes, recent moves, and the top alternatives to consider.
Miter vs OpenCATS: at a glance
What is Miter?
Miter added accounts payable and opened a free API — it's no longer just construction payroll.
Miter ships one large digest every one to two months rather than continuous entries, and each is organized by module: HR, Payroll, Field Ops, Spend, Platform, Ecosystem. The summer update is the broadest yet, adding an Accounts Payable module, API 2.0 as a free self-serve install, Safety Passport credential verification, entity-scoped granular permissions, and a run of payroll and compliance work including California break rules and OSHA report generation.
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.

Miter
3.8HR
Miter added accounts payable and opened a free API — it's no longer just construction payroll.
◆ Current state
Miter ships one large digest every one to two months rather than continuous entries, and each is organized by module: HR, Payroll, Field Ops, Spend, Platform, Ecosystem. The summer update is the broadest yet, adding an Accounts Payable module, API 2.0 as a free self-serve install, Safety Passport credential verification, entity-scoped granular permissions, and a run of payroll and compliance work including California break rules and OSHA report generation.
◆ Where it's heading
The module list keeps growing outward from payroll into everything a contractor's back office touches, and the last two releases added the two things a platform needs that a payroll product does not: a spend module of its own and an open, unmetered API. Vote counts published against each feature show the roadmap is being run off customer demand, and the compliance work is concentrated where construction is most exposed — break rules, OSHA, prevailing rate calculations.
◆ Prediction
Expect the Spend module to keep filling out around Accounts Payable, and third-party integrations built on API 2.0 to start appearing in the Ecosystem section of the next digest.
OpenCATS
6.3HR
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.
