What is Envoy?

Envoy turned the roster it already had into a physical-security product, and is now hardening it.

The August 7 release moved Envoy into threat monitoring: a Threat Dashboard tracking verified global and local risks, employee home addresses synced from HRIS, and per-individual monitoring for executives and other VIPs. The releases since have been operational hardening — location-scoped blocklists so site teams can act without touching the company-wide list, and an audit log covering published changes to the workplace map. Around that, steady platform work continues across Visitors, Workplace, Screens, and the Developer API.

What is OpenCATS?

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

Envoy vs OpenCATS: editorial side-by-side

E6.3

Envoy turned the roster it already had into a physical-security product, and is now hardening it.

◆ Current state

The August 7 release moved Envoy into threat monitoring: a Threat Dashboard tracking verified global and local risks, employee home addresses synced from HRIS, and per-individual monitoring for executives and other VIPs. The releases since have been operational hardening — location-scoped blocklists so site teams can act without touching the company-wide list, and an audit log covering published changes to the workplace map. Around that, steady platform work continues across Visitors, Workplace, Screens, and the Developer API.

◆ Where it's heading

Envoy is converting data it already holds — locations, employee directory, desks, visitor records — into products that sit beside the originals rather than requiring new collection. Response is the clearest instance: it works out of the box for every existing location and deepens when the HRIS directory sync shipped in July is switched on. The two releases that followed suggest the near-term concern is making these surfaces auditable and delegable enough for multi-site administration, where a single global list or an untracked map edit becomes a real operational problem.

◆ Prediction

Response most likely gains administrative depth next — alerting rules, roles, and reporting — following the same scope-and-audit pattern just applied to blocklists and the workplace map. The entries give no indication of how Response is packaged or priced against the existing plans.

O2.5

OpenCATS breaks a two-year quiet with v0.10.0, tightening attachment auth and form UX

◆ Current state

OpenCATS, an open-source applicant-tracking system, ships rarely — its release history spans 2020 to 2026 with long gaps. The new v0.10.0 ends a roughly two-year quiet since the 2024 maintenance line, adding authentication on the attachments module, form-validation and default-company improvements, non-ASCII handling, and a JS back-button fix. Prior releases were predominantly security and PHP-compatibility maintenance.

◆ Where it's heading

The pattern is a community project moving in slow, security-conscious increments: authenticated attachments and earlier XSS/cookie hardening show steady attention to securing an aging codebase. v0.10.0 suggests renewed maintenance momentum rather than a feature pivot.

◆ Prediction

Expect continued infrequent releases focused on security hardening and PHP-version compatibility. A jump in cadence would be the signal to watch for renewed active development.
