Proof might be a bit more popular than Mutiny. We know about 1 link to it since March 2021 and only 1 link to Mutiny. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
This has small echoes of what Mutiny (mutinyhq.com) is already doing. I think their pitch is basically "we segment who's coming to your website and then show different versions of the landing page", but I do think that they're moving into some different areas (e.g. Automatically writing copy using GPT3 to target specific users).
