What motivated you to purchase a developer tool that you had been using for free for several months?

I was on a free plan for too long, but it wasn't because of limitations. Buying was an admission that my project was real. The day I upgraded was the day I had to maintain the history of the funnel beyond the free plan's capability, and I realized that I was treating the app as a disposable item that I checked every morning.

This made me think of what pushed people over the edge. For me, it was never the list of features. It was a little bit of friction at a critical moment, such as losing my data or hitting a limit while debugging.

I wonder how it turned out for you. Was there a time when the free product turned into a paid one? And has a paid product ever caused any regrets because the free one was actually good enough?

Solo developers are especially welcome to share their experiences. We have stricter requirements for products due to limited budgets.
