Macrowave.co was the attempt to program my own HTTP-monitoring-service from scratch. I used this project to familiarize myself with AWS and serverless architecture. I had a BETA that worked really well and that I could rely on. The service had servers on every continent of the planet and would have been useful for non Europeans, too. I abandoned it after I had a paying customer and the feeling that the competition was miles ahead of me. It was a very good exercise and I'm really glad I did it. Macrowave was my first 100% self produced SAAS. Me and a few friends are still using it to monitor some of our and our customer websites.
At this point I would like to thank Chris and Robin who helped me to develop the best possible product and for the countless hours in which they tested it.
You can still sign up and use it. macrowave.co.
