I'm working on https://suggestionboard.io, a simple live polling and Q&A webapp that doesn't require an account. Just launched the first version and trying to figure out if there's a market.
Feedback board or feature board are the terms, and there's a plethora of SaaS options, from tiny to large.
I recently searched for one, but they were either over budget, required extra user accounts, weren't GDPR compliant, or too complex. In the end, I coded a custom solution for my site.
Yours would have fit if I had found it earlier.
I liked nolt.io from the design and stuff. But it does too much, and the monthly price didn't fit for a simple test. The others in that league were the same. The indehacker's are mostly not GDPR-compliant and have this doom-laden smell of neglect.
