My name is Joe, and I am the co-founder of Budibase. I have built many apps in the past, which, I guess is why I am building a platform that builds apps super-quickly and easily. In the last year, the following tools have helped me, and my team a lot. As a way of showing gratitude, I thought I’d share these tools with like-minded people, and hopefully, they can help you too.

This is an opinionated list and there are possibly better tools out there. If you know a better alternative, please comment below. We’d love to add more tools to our arsenal, and it’s nice, for the makers of these tools, to feel appreciated. See the list.
