What is the difference between a web app and a website?

A website is mostly content to read; a web app is software people work in for hours: dashboards, SaaS, admin and workflow tools. The craft is density and state handling, so a studio strong at brochure sites is often not the right pick here.

What does web app design cost?

MVP design commonly starts in the tens of thousands, design-and-build runs into six figures, and platform-scale work higher. None of these studios publish rates, so approach two or three in parallel.

Should design and engineering come from the same studio?

For dense software with permissions, roles, and data tables, a combined team keeps interaction detail and the empty, loading, and error states from getting lost in a handoff. Design-only works if your engineering is strong.

How do studios handle all the empty, loading, and error states?

Ask to see them. Mature web-app studios show empty states, error handling, and dense data views, not just populated happy paths. Those states are most of the real work.

Will they build a design system?

For a web app that will grow, a component library or design system keeps it consistent and faster to extend. Most of these studios build one as part of the engagement.

How long until launch?

A scoped MVP design is typically six to twelve weeks, and design and build to a first release is more commonly four to nine months. Platform-scale products take longer.

The profiles

Web app design in full

Clay Global

SaaS and enterprise web software, from a studio built on it.

Clay's origins are in enterprise and SaaS UX, which is the web-app discipline itself, and it grew a full product and brand practice around that core. For complex browser software that also needs a coherent identity, both come from one team rather than two vendors.

Notable work: Product and interface work for Google, Amazon, Slack, Coinbase, Snapchat, Sony, and Stripe.
