10 Best SaaS App Reference Websites for UI, UX & Product Research (2026)
Jun 4, 2026 • 7 min read
Designing a SaaS product is rarely about starting from a blank canvas.
Most designers start with references. No matter what problem you are trying to solve with your SaaS, chances are that someone else has already done it (or at least a part of it!).
The fastest teams don’t start reinventing the whole flow. They study what has already been done and try to add on that.
That’s why SaaS app references or inspiration websites have become essential tools for designers, product managers, founders, and developers. The challenge is that different tools solve different parts of the research process. Some focus on landing pages, some UI screenshots, and some on product flows.
In this guide, we’ll look at the best SaaS reference websites for researching product flows, UI patterns, onboarding experiences, and real-world design solutions.

Why Product Flows Matter More Than Screenshots
A screenshot can show what a page looks like.
A product flow shows why it exists.
When designing onboarding, billing, invitations, notifications, or settings experiences, understanding the sequence of interactions is often more valuable than studying individual screens.
That’s why product flow research is becoming a core part of modern product design workflows.
