PingBot is a lightweight website and API monitoring tool packaged as a Ruby gem. It provides an executable that launches a web application (powered by Sinatra and SQLite) where you can add or remove URLs to monitor. The gem periodically checks each endpoint for availability (HTTP 200 OK), tracks their status, and displays the results in a user-friendly dashboard. No external dependencies or accounts required—just install the gem, run the executable, and start monitoring your endpoints in seconds.
