100 Top Observability Tools (+ Server Monitoring and APM solutions)
Looking for application monitoring and observability solutions? On this page, I’ve listed the top application performance monitoring (APM), infrastructure monitoring, and observability solutions to date. The listings are updated periodically as APM and observability solutions continue a rapid evolution.
While I haven’t tested all of these solutions, I’ve used more than a third of them. Some, I have been using for more than a decade. My hope is that this list serves to be both a useful and time-saving page that we can all fall back on.
Whether you manage web servers, develop web applications, SaaS products, or mobile apps, this list should be of interest to you. You probably won’t find a more up-to-date list of solutions and tools. For a slightly smaller more focused list, have a look at the 50 Top Server Monitoring, APM and Observability Tools.
This list started with approximately 20 solutions listed and has since grown to over 100 solutions! In random order…

Keep the suggestions and feedback coming. Thanks!
I don’t use any paid solutions and I like to self-host where possible.
I currently host an instance of Uptime Kuma to track website uptime, very nice software.
A FOSS website performance monitor would be nice as well, but I haven’t found a good one yet. Any suggestions?
I would suggest Zabbix, Munin, Nagios, Cacti and MONIT.
Zabbix does look like nice software, I’ll have to tinker with it at some point.
At the moment I am deploying Netdata to monitor our infrastructure. It is very comprehensive and has a great plugin ecosystem, highly recommended.
