What our happy customers say

We've been really enjoying Knapsack Pro, it's been saving us a ton of time.

Knapsack Pro has helped us build an insanely fast and scaleable build pipeline with almost no setup or maintenance.

Your no-pressure sales model really worked for me. The fact there was no pressure and we were getting value really helped me make the purchase decision.


My project is still pretty small but it’s getting new users and I’d like to validate whether I should continue work on it so people can rely on Knapsack Pro in their daily work.

The best way to do that is to find happy users willing to support my work.

No matter if your organization is small or big. We can find fair pricing.

Thanks for your support!
