"Anything that short-cuts a lengthy discussion with stakeholders is valuable to me. Northbase gives me thoughtful starting blocks on various UX patterns without having to investigate in depth myself."

Harrison McEwen • Principal Product Designer, Hyperlayer

Research you can cite

Every pattern is backed by quantified research across 10+ enterprise systems. Verifiable data, not opinions.

Empty States

Icon + Headline + CTA is the universal default at 29%

GitHub settings collaborators page showing zero collaborators with a people icon, headline and Add people button
Use icon + headline + CTA as your default for settings, admin panels, and feature-specific views.

Permission & Access Control

Only 4 of 7 systems offer a recovery path on access-denied pages

Notion access denied page showing lock icon, 'No access to this page' headline, 'Request access' and 'Back to my content' buttons, and 'Logged in as jan@casestudy.club' at bottom
Show a 'Request access' button as primary CTA and the logged-in account with a switch option as secondary.

Error States

'Can't/Couldn't [action]' takes ownership at 16% of headlines

Atlassian toast showing 'Couldn't create the work item' headline with body text 'We're having some trouble creating the work item. Refresh the page and try again.'
Use "Can't" or "Couldn't" when the system is at fault. Add "We" before the contraction for stronger ownership.

Data from products you already know

Analyzed across 10+ enterprise systems including Notion, Stripe, GitHub, and more.

"I need conviction in my decisions, and I also have to arrive at them quickly. I have enough visual inspiration with Mobbin, and need a little more 'why'."

"The value was so compelling that rather than just a solo account, almost a dozen colleagues also expressed interest. This is an amazing thing you've got going."

Frequently asked questions

We've compiled the most important information to help you get the most out of your experience. Can't find what you're looking for? Contact us.

Who is this for?

Designers and product managers who need confidence in their UX decisions. If you've ever spent 30 minutes explaining a pattern choice without data to back it up, Northbase gives you the reference in seconds. Design system teams and agencies building B2B products use it to make decisions faster.

How is this different from Mobbin or Refero?

Mobbin and Refero are screenshot libraries — you browse examples and identify patterns yourself. Northbase does the analysis for you. We quantify what's common ('9 of 10 systems use X'), document microcopy patterns, and provide decision frameworks. You get data you can reference in a meeting, not just inspiration. Screenshots are free; the analysis is the value.

How many patterns are included?

Currently 5 patterns (Empty States, Error States, AI Input, AI Output, Permissions) with new patterns added regularly. All plans include full access to the current and future pattern library.

Can I browse before subscribing?

Yes. Individual screen pages are completely free—see exactly how Notion handles empty states, or how Slack designs error messages. Pattern previews show a portion of the analysis free. Subscribe to unlock full analysis.

How do I know the research is legit?

Every statistic is verifiable. We show our work — all examples are organized by system on our platform. When we say '8 of 10 systems do this,' you can see which eight. That's the kind of claim you can confidently cite in a design review.
