I probably made the most affordable feedback tool for indie hackers

I've been working on Productroad, a tool for collecting feedback and voting for feature-requests, for over a year now.

Many people have used our free plan, but it is limited in the number of customers. Today I've added a new full-fledged plan for indie hackers for $9, and I've removed all restrictions on the number of users on all plans.

I think my product is now the most affordable on the market. What do you think? If you know of more affordable options, post in the comments.
