In plain words
Kaffeine is a tool designed to prevent free Heroku applications from entering sleep mode due to inactivity. It works by sending periodic requests to keep apps active and running. The service is intended for developers who maintain free-tier Heroku projects and want to ensure continuous uptime without upgrading to paid plans. It addresses the common problem of free dynos automatically sleeping after 30 minutes of inactivity.
