What OpenCATS is

OpenCATS is free, community-maintained applicant tracking and recruiting CRM software for staffing agencies and internal recruiting teams. It manages candidate records, resumes, notes, status history, jobs, companies, contacts, submissions, and follow-up activity. Listed recruiting tools include a career site, interview scheduling, workflow automation, and job-board distribution. Resume parsing is not included. OpenCATS is self-hosted and web-based, allowing teams to inspect the code and keep recruiting data under their own operational policies. The documented runtime requires PHP 8.4.1 or later within PHP 8, MariaDB, a web server, and required PHP extensions. MariaDB is the recommended and tested database family; MySQL is not the documented target. Optional utilities such as Antiword, pdftotext, html2text, and unrtf can improve document extraction and search. Version 0.11.1 is identified as a security and maintenance release. Documentation covers installation, configuration, upgrades, and maintenance, with peer support available through the OpenCATS subreddit.
