I???ve been building a SaaS startup for a couple of years now, and one of the things I noticed after a few months of operation is that all those small subscriptions I had for various things needed for the operation of the startup really start to add up. We have enough revenue now that those subscriptions don???t matter so much, but there was a time when they were a burden, particularly since we were bootstrapping. I got to thinking whether it would be possible to build a startup stack with $0 in monthly subscriptions, and after putting together a list of the various tools we???ve been using, and looking for replacements for some of them where you can avoid the monthly subscription, I figured that this would be quite doable.
