Agent Slug is a little creature, that would be happy to monitor any website's uptime. It's simple, cheap as a chips and fully functional. And it gets good reviews, what makes me happy personally.
Uptime monitoring is not enough for us and we want to build on it a complementary webmaster tool, focused on a website monitoring in many dimensions.
We built this application to scratch our own itch. It can not fail, because we would have at least one client - our team.
Of course, our approach is to acquire as many clients as possible. That's why we created a roadmap of the main functionalities we must have to call this app a toolbox.
For example, our roadmap includes:
- full content monitoring
- dead links detection
- html validation
- WAI problems detecting within the content (like no [alt] attributes on images)
- anomalies detecting – if your homepage suddenly grows or shorten it might be hacked (defaced)
- real users’ load time count
- resources load time count
