Hello HNer, I have built this simple tool because I needed it for another project. My aim was to produce a scalable, and fault-tolerant "fire-and-forget" SaaS capable of scheduling recurrent workloads in the same manner as cron, but scalably and independent of caring about the machine it runs on. I built it on AWS SQS delay queues, EB workers, with a worker to keep the time ( process the webhook jobs ) and a supervisor worker to make sure all "currently live" jobs are firing. Coupled with rolling updates, the result is, I believe, a good start at a fault tolerant, reliable and scalable system for using jobs. It's not a very complicated SaaS product, but it's my first "full stack" offering that includes an API, a console, payment, and a fault tolerant backend. A fully self-contained project. I hope to make some money and customers from this, and I welcome your feedback to help me achieve this. I've created some free API keys for you to use (chronos and phanes) and if you end up buying a subscription use TOTALRECALL for 70% off first month. I really have no idea how to successfully do this (profit from SaaS) but if anyone can guide me to do that in this humble and simple offering, it will really be helpful for me with the more ambitious projects I hope to release as well. Thanks for reading. Enjoy the free demo.
