Lattice vs OpenCATS: at a glance
What is Lattice?
Lattice built an AI agent worth visiting, then handed its data to everyone else's.
Lattice runs AI Agent as its own changelog category alongside Performance, Compensation, and Analytics, and the June work built it into something worth opening: the Agent attends 1:1s and captures summaries, action items, and coaching insights, answers data questions with charts rather than prose, and takes voice input. July then pointed the same capability outward. An MCP server exposes Lattice to Claude, OpenAI, and Slack, and AI review drafts are assembled from a person's own 1:1s, feedback, goals, and updates with cited sources. Underneath both, the performance and compensation machinery keeps absorbing manual setup — calibration groups generated from the org chart, approved promotions carried from a review cycle into a comp cycle.
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.

Lattice built an AI agent worth visiting, then handed its data to everyone else's.
◆ Current state
Lattice runs AI Agent as its own changelog category alongside Performance, Compensation, and Analytics, and the June work built it into something worth opening: the Agent attends 1:1s and captures summaries, action items, and coaching insights, answers data questions with charts rather than prose, and takes voice input. July then pointed the same capability outward. An MCP server exposes Lattice to Claude, OpenAI, and Slack, and AI review drafts are assembled from a person's own 1:1s, feedback, goals, and updates with cited sources. Underneath both, the performance and compensation machinery keeps absorbing manual setup — calibration groups generated from the org chart, approved promotions carried from a review cycle into a comp cycle.
◆ Where it's heading
The interesting move is that Lattice stopped assuming it wins by being the app you open. June made the Agent a destination; July made Lattice reachable from Claude, ChatGPT, and Slack instead, which is a bet that being the HR data layer beats owning the chat surface. Review drafts show what that data layer is being accumulated for: the meeting capture, feedback, and goals the Agent has been collecting are now the raw material for the review itself, with citations as the trust mechanism. Compensation is on a slower and more procedural track, closing loops — sending recommendations back for revision, exporting with HRIS IDs attached — rather than adding AI.
◆ Prediction
Expect the review-drafting work and the MCP surface to converge, so a manager can draft an evidence-cited review from Claude or Slack without opening Lattice. Whether compensation gets the same treatment is genuinely unclear from these entries — that area is still being hardened procedurally, and approval chains carry consequences that make an AI draft a harder sell.
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.
