Web Application for Developers to Monitor Their Cron Jobs

http://www.cronly.app
I built Cronly entirely by myself, both the front end and the back end. It is an application that allows developers to monitor or manage their cron jobs from the cloud. Integrations with tools like Slack, LogSnag, or Zapier enable them to stay on top of issues with their monitors.

The project exemplifies my excellent Laravel knowledge, where almost every best practice was followed.
