Agent Slug is a little creature that would be happy to monitor your website. It can monitor a website’s uptime and test a whole website by looking for broken links.
Uptime monitoring is not only about getting information when your website is down. It's also about getting insights into how your website is performing from different locations in the world. From the first second after your test is deployed you are protected against being unaware of website downtime by getting notifications via e-mail or Slack. After one hour you get performance insights. We are currently executing uptime tests from London, Strassburg, Frankfurt am Main, N. Virginia and Warsaw.
Additionally, it's possible to scan the whole website. During the scan, Agent Slug browses the website by looking for every broken link in the content. Tests can be scheduled or started ad-hoc. Finding broken links is pretty cheap - it costs only 1€ for a full scan of a website with a 10,000 links. The first test is completely free (and there's even a 5€ welcome bonus!).
