Sensu vs Uptime Robot: What are the differences?

Developers describe Sensu as "Open source monitoring framework". A monitoring framework that aims to be simple, malleable, and scalable. Essentially, Sensu takes the results of “check” scripts run across many systems, and if certain conditions are met; passes their information to one or more “handlers”. Checks are used, for example, to determine if a service like Apache is up or down. On the other hand, Uptime Robot is detailed as "Free website uptime monitor". Uptime Robot is all about helping you to keep your websites up. It monitors your websites every 5 minutes and alerts you if your sites are down.

Sensu can be classified as a tool in the "Monitoring Tools" category, while Uptime Robot is grouped under "Website Monitoring".

Some of the features offered by Sensu are:

  • Execute service checks
  • Send notifications
  • Collect metrics

On the other hand, Uptime Robot provides the following key features:

  • http(s): that's perfect for website monitoring. The service regularly sends requests (which are the same as if a visitor is browsing your website) to the URL and decides if it is up or down depending on the HTTP statuses returned from the website (200-success, 404-not found, etc.)
  • ping: this is good for monitoring a server. Ping (ICMP) requests are sent and up/down status is decided according to the "if responses are received or not". Ping is not a good fit for monitoring websites as a website (its IP) can respond to ping requests while it is down (which means that the site is down but the server hosting the site is up)
  • keyword: checks if a keyword exists or not exists in a web page

"Support for almost anything" is the primary reason why developers consider Sensu over the competitors, whereas "Free tier" was stated as the key factor in picking Uptime Robot.

Sensu is an open source tool with 2.96K GitHub stars and 388 GitHub forks. Here's a link to Sensu's open source repository on GitHub.

Geocodio, Avenue.io, and Gimanzo Systems are some of the popular companies that use Uptime Robot, whereas Sensu is used by SendGrid, Airbrake, and SimpleCrypto. Uptime Robot has a broader approval, being mentioned in 61 company stacks & 22 developers stacks; compared to Sensu, which is listed in 30 company stacks and 7 developer stacks.
