Pretty cool! Just a heads up: the video is not loading in my browser (Microsoft Edge with uBlock Origin on default settings, IP address in the EU), it's stuck on "Loading video...".

I'm probably not your ideal customer, so take this with a pinch of salt, but I think you're shooting yourself in the foot by segmenting your pricing by "number of landing pages".

I would instead price by features. For example you could segment pricing by the number of blocks you can track on a page. Free users only get 3 blocks, paid users get 50 blocks, enterprise users get unlimited blocks.

You want to be able to convert users that are only going to need the tool on a small number of landing pages. I may be wrong, but I can't imagine anyone needing detailed analytics on 100+ landing pages

You should dig deeper into your market research. Analytics platforms do exist that provide this level of detail. That doesn't mean you shouldn't build another one - the fact they already exist means the problem is validated. But it does make you look like someone just dipping their toes into a new idea, not an expert in this problem space. There is nothing wrong with that - everyone is new to their work/market at the beginning. But you don't want to be raising a big flag announcing it. You need to be differentiating yourself from what exists, not acting as if you are new. And say that you measure A/B tests, don't describe them as if you had never heard the term.

But to answer the question of what we think about the product itself... I kinda despise client-side analytics that make calls out to 3rd parties (even if it is just a tracking pixel). I understand the value to marketers and PMs. But if you want something new in this problem space, send data to the app server and build server-side processing. Not only is that a cleaner client-side experience, it won't end up getting blocked by anti-spyware extensions.

Also, you are shooting yourself in the foot by measuring landing pages. They are already a fairly weak form of marketing - they are early idea validation, not even a real product. Optimizing at this point is borderline bike-shedding. You need these types of analytics when you have a product ready to roll and are optimizing conversions. Landing pages simply are not high value enough to invest this much effort.
