That reminds me of Airbrake.io, whose lowest-cost pricing plan was higher than I wanted to spend on a toy site I made recently. On my phone I can't find the text on their site, but in small print on the pricing page it said something like "or, we have a developer plan, which is free for one site and one user."

It was exactly what I was looking for, and I wish there were more ultra barebones plans available for otherwise-paid services.
