Developing a SaaS product isn’t for everybody but if you are a developer and want to expand your breadth it’s a wonderful and rewarding challenge. Nothing is easy but there has never been more resources, support and tooling for indie SaaS makers. If you want to get started the indiehackers community is fantastic and my inbox is always open for answers/encouragement Shane at Cronitor.io
The hardest part about building a SaaS product for me isn't the technical challenges (although there are some too), it's mostly anxiety. The thing that scares me the most is launching and receiving negative feedback, the thought alone is enough for me to stop working on it.
Also, you’d be surprised how most people sound harsh but actually don’t really mean to. They’ll most likely completely change their tone after you’ve contacted them and tell them you’d like their opinion on future improvements. Also, if by any chance those people finaly use your product, you have a high chance that they become strong proponents and advertisers for your product.
