We love CandidATS because it is a free, open-source ATS. It has so far been used by thousands of businesses in over 130 countries to track and manage applicants.
Created by Aueio, CandidATS is a free open source ATS. Its features include a centralized candidate management tool, an easy to search database for resumes, email templates, and interview scheduling capabilities.
The creators of CandidATS are available to help with any issues that may arise.
CandidATS's UI isn't as friendly as many modern ATS's.
CandidATS is completely free to download. However, customization services cost $25/hour.
