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.
What is Fountain?
Fountain is wiring AI agents across the hourly-hiring lifecycle, from sourcing to retention.
Fountain runs two parallel build-outs: an agent layer (Cue for recommendations, the Candidate AI Agent, and now Sam for post-hire satisfaction) and a sourcing-and-attribution stack centered on Source. Recent releases lean on closing the loop between ad spend and actual hires, and on extending automation past the point of hire into worker retention.

◆ 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.
Fountain
7.5HR
Fountain is wiring AI agents across the hourly-hiring lifecycle, from sourcing to retention.
◆ Current state
Fountain runs two parallel build-outs: an agent layer (Cue for recommendations, the Candidate AI Agent, and now Sam for post-hire satisfaction) and a sourcing-and-attribution stack centered on Source. Recent releases lean on closing the loop between ad spend and actual hires, and on extending automation past the point of hire into worker retention.
◆ Where it's heading
The product is expanding its AI agents from the front of the funnel toward the back: onboarding check-ins, satisfaction, and rehiring logic. Source is maturing into a full media-buying surface with channel-level cost data and server-to-server attribution. Expect agents to own more of each lifecycle stage and sourcing to become a spend-accountable channel.
◆ Prediction
Sam graduates from coming-soon to general availability, and Fountain ties its satisfaction signals back into rehiring and sourcing decisions to close the retention loop.
