Open Source alternative Pagerduty/Opsgenie for managing OnCalls and Alerts
Most of the tools you find are paid tools and open-source community-driven projects act as adrenaline because it’s FREE!!!!
Open source Softwares win all battles in the startup world, while big enterprises have complex use cases hence fail.
After doing some research we found a few really good open-source projects by tech giants like Netflix, LinkedIn, Target, SoundCloud & CNCF.
If you are thinking your team would start getting free calls/SMS once these tools are installed, then I am sorry for breaking your heart. Pagerduty & Opsgenie have inbuilt SMS/calling feature and many more leading features that come at a cost.
But if you are really interested in doing some job on your own and some through open-source without spending a lot of money on pagerduty or opsgenie. You can definitely try it out following tools.
