"The flexibility of Knapsack makes it an ideal tool for us to integrate into existing build processes to ensure design, product, and development are all on the same page with the components we have, how to integrate them, and to ensure the stability of those components as they change."

"Knapsack is closing the gap on the oh-so-familiar product problem: it unites design, product, and development teams with a source of truth that fits in happily with existing toolsets. The flexibility of the tool means we don't have to upend our current workflows to use it, and Knapsack's ease of use allows for folks across our company to interact with it. 10/10."
