I'm also biased because I work on Gripeless. Our product isn't really about broadly collecting feedback as a whole, but it instead focuses specifically on the negative feedback part and tries to make it as pleasant and friction-less as possible for the end user to submit. HotJar's feedback tool is built around getting all kinds of feedback, both positive and negative, which is generally fine if you want to improve your product satisfaction when comparing "happiness" at different time frames, but it does come with some caveats. Since people don't want to be rude by nature it's less likely that they'd explicitly pick the most angry face option on HotJar's happiness slider and submit their complain then - as they, again, would have to explicitly state that they're dissatisfied. Submitting a gripe through Gripeless on the other hand takes just a single text field, no emotions, no decisions - users can simply quickly fire out their issue(s) at the product owner without any suspected judgement - since complaints are very clearly solicited. Again, I'm super biased because I'm the solo founder of Gripeless and competing against a much more established company like HotJar is not easy, as an early stage company we can't afford to give out our product for free just yet (apart from OSS projects which we always give out our product to for $0), but I try very very hard to satisfy our current customers' specific needs, something that a larger company can't offer at scale.
