This isn't from the TanStack creators, despite using their name (see footer disclaimer).
They are pitching this as a launch (first 20 buyers get a discount!), but their YouTube review videos are 5 months old with 67k views (looks like paid creators).
This looks like just another paid template hustle.
Tanstack always had one of the best data tables by far. But component libraries as a business model are dead in the water at this point sadly. Your whole product can be replaced with a few minutes of prompting now. Abstract design languages for agents to build around are the future, not concrete implementations.
