OpenCATS: Open Source Applicant Tracking System Guide

OpenCATS is a robust, free, and community-maintained open-source Applicant Tracking System (ATS) designed to empower recruiters and HR teams. This powerful platform streamlines the entire hiring journey, from initial job postings to successful candidate placements. Unlike proprietary systems, OpenCATS is a self-hosted solution, granting organizations complete sovereignty over their recruitment data and operational workflows, free from vendor dependency. Built for ownership and clarity, OpenCATS offers a comprehensive suite of tools for managing candidates, job requisitions, and all associated hiring activities. Its open-source nature means the underlying code is accessible, allowing for modifications and contributions from a vibrant community of users and developers.

Establishing Your Foundation for OpenCATS Deployment

• A Linux/Unix server environment (Ubuntu is a primary documented path) or a Windows environment with WAMP/XAMPP for installation.
• A web server such as Apache or Nginx to host the application.
• PHP 8.4.1 or later within the PHP 8 series, along with necessary PHP extensions.
• A MariaDB database (version 10.7 recommended) or MySQL, configured with appropriate permissions.
• Composer for managing PHP dependencies, particularly when installing from source.
• Optional document parsing utilities like antiword, pdftotext, html2text, and unrtf are recommended for enhanced resume and document text extraction capabilities.
• Users should possess technical expertise for successful setup, configuration, and ongoing maintenance of the self-hosted system.

Accessing Your OpenCATS Recruitment Dashboard

1. After successfully installing OpenCATS on your chosen server, navigate to your configured web address where OpenCATS is hosted.
2. Locate the login screen, which typically presents fields for a username and password.
3. For the initial access after installation, common default credentials are often admin for the username and either admin or cats for the password.
4. Immediately upon your first successful login, access the settings or user management section within the application to change these default credentials to strong, unique passwords. This is a critical security step for your recruitment portal.
5. For ongoing user access, user accounts with varying access levels can be managed through the Access Control List (ACL) system, allowing for granular permissions based on roles.
