I recently had to choose between Django and Ruby on Rails (RoR). I’ve used Django for smaller projects but had never tried RoR. I picked these two because I think single-page applications (SPAs) are often more than what’s needed. After looking into Next.js, I realized I'd have to learn a lot to use it properly, and I didn’t want to dive into that. I just wanted to get started without dealing with complicated tools.

After thinking it over, I decided to give RoR a shot. The framework does a lot for you, which can be frustrating if you’re used to having control over everything. Still, I was surprised by how much I could accomplish in just a few days. The productivity is impressive, especially for startups that need to get things moving quickly.

So if you just want to prove a business idea, your customers don’t care what tools you use. I’d rather pay twice the price to scale in RoR than spend double the time developing a feature. I would earn it back with the additional customers I gain by pushing features faster out the door.
