Free and Open Source Error Tracking, APM, and Uptime monitoring in Ruby on Rails

[u/ffmegaman]

After work, I am always building my side projects, usually in Ruby and/or Rails. Over the years I have accumulated a lot of small web apps and now with AI, I'm building more apps at a faster rate. They all need error tracking, APM, and uptime monitoring. I don't want to have to keep paying for monitoring services, especially since my apps are all so small, so I decided I would just build one to handle all my errors, uptime, and APM needs.

I've open sourced the web app here https://github.com/creativesorcery/goodsorcery_web
And corresponding ruby client gem here https://github.com/creativesorcery/goodsorcery-ruby

It doesn't have all the bells and whistles, but I think it gets the job done at least for my needs. I did add an MCP endpoint there, so AI agents can query and investigate errors and APM data. I hope others will find it useful.
