Codility vs OpenCATS: at a glance
What is Codility?
Codility rebuilds technical assessment around the AI-era engineer
Codility has reoriented its technical-assessment platform around AI on two fronts: measuring how candidates work with AI (an AI Copilot inside interviews, an AI Readiness assessment framework) and establishing authority on evaluating AI-generated code (the COMPASS benchmark). Recent posts also cover the defensive side — detecting AI-assisted cheating and holding to SIOP validity standards.
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.

Codility rebuilds technical assessment around the AI-era engineer
◆ Current state
Codility has reoriented its technical-assessment platform around AI on two fronts: measuring how candidates work with AI (an AI Copilot inside interviews, an AI Readiness assessment framework) and establishing authority on evaluating AI-generated code (the COMPASS benchmark). Recent posts also cover the defensive side — detecting AI-assisted cheating and holding to SIOP validity standards.
◆ Where it's heading
The company is shifting from testing raw coding skill toward measuring AI-era engineering skill, betting that judgment about AI collaboration and code quality is the durable value as raw code generation commoditizes. COMPASS doubles as research credibility and a positioning moat.
◆ Prediction
Expect AI Copilot and AI-readiness assessments to move from blog and research framing into packaged product offerings, and COMPASS to expand its problem set or get repositioned as a buyer-facing tool for comparing models.
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.
