What Watir is
Watir is a free, open-source Ruby library for automating web browser tests. Scripts can click links, fill forms, and check text while working with buttons, check boxes, dropdowns, frames, links, radio buttons, and text inputs. Project guides list Chrome, Firefox, Internet Explorer, Safari, and Edge. Documented capabilities include automatic waits, headless operation, mobile testing, authentication, certificates, proxies, cookies, alerts, and screenshots. The ecosystem includes watir-rails for Rails and watir-rspec for RSpec. Watir runs on Linux, macOS, and Windows and supports self-hosted use; cloud execution is not available. The project describes it as suited to people starting in test automation. Volunteers maintain the library, directing reproducible problems to issues or pull requests and general questions to Stack Overflow. Watir cannot operate operating-system file dialogs. Browser downloads on a remote machine remain on that machine rather than the computer running Ruby.

Verdict
Watir offers broad browser interaction and testing capabilities across desktop platforms at no cost. Its self-hosted approach fits Ruby teams, but file-dialog handling and remote-download behavior impose operational limits.
