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 Envoy?
Envoy moves ID verification in-house with proprietary AI, breaking from third-party scanning vendors.
Envoy operates across three distinct modules — visitor management, workplace desk/space operations, and physical security response — and has been shipping consistently across all three. The standout move is the in-house ID scanning infrastructure: name verification, face matching, extended document types, and blocklist integration, all built on Envoy's own AI stack rather than a vendor API.

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.
Envoy
6.3HR
Envoy moves ID verification in-house with proprietary AI, breaking from third-party scanning vendors.
◆ Current state
Envoy operates across three distinct modules — visitor management, workplace desk/space operations, and physical security response — and has been shipping consistently across all three. The standout move is the in-house ID scanning infrastructure: name verification, face matching, extended document types, and blocklist integration, all built on Envoy's own AI stack rather than a vendor API.
◆ Where it's heading
Envoy is consolidating the physical security stack. The pattern across the last 6 weeks runs from identity verification at the door (ID scanning) to threat monitoring in the field (travel risk, VIP protection) to compliance documentation after the fact (audit logs, export templates). These aren't isolated features — they're the components of a full security incident lifecycle, and Envoy is building each one natively.
◆ Prediction
The next move is likely automated cross-module triggers: when a visitor matches a blocklist or fails ID verification, the Response module fires an alert automatically rather than requiring a manual handoff. The infrastructure for both sides is already in place.
