WHY TEAMS SWITCH

Why Teams Choose Hubble over Userbrain

Userbrain is a simple, affordable way to run unmoderated think-aloud tests. Hubble adds what Userbrain doesn't offer: AI-moderated interviews, in-product surveys, card sorting and tree testing, and a participant CRM for your own users.

MCP

A more capable MCP

Userbrain's MCP reads test results. Hubble's MCP can also plan research, publish studies and recruit participants from Claude, ChatGPT or Cursor, with approval on every change.

IN-PRODUCT

In-product surveys

Ask targeted questions inside your product with SDKs for web. Target by event, attribute or URL, and control frequency and delay.

AI MODERATION

AI-moderated interviews

Userbrain doesn't run AI-moderated interviews. Hubble's AI moderator runs full interviews from your discussion guide and probes in real time during live website tests, scaling to hundreds of sessions at once.

“We use Hubble for our AI-moderated studies and Figma prototype usability tests. The large pool of testers has been really helpful for our usability testing projects, and we get great support from their customer success team.”

Frequently asked questions

What is the biggest difference between Hubble and Userbrain?

Userbrain focuses on quick, affordable unmoderated think-aloud tests. Hubble covers unmoderated testing too, and adds moderated and AI-moderated interviews, card sorting and tree testing, in-product surveys, a participant CRM and an MCP server that can launch studies.

Is Hubble a good alternative to Userbrain?

Yes, especially for teams whose research has grown beyond unmoderated tests. Hubble covers the same core methods as Userbrain (unmoderated, prototype and live website testing) and adds interviews, card sorting, tree testing, in-product surveys and enterprise security.

Does Userbrain offer moderated or AI-moderated interviews?

No. Userbrain supports unmoderated testing only, and uses AI for test setup and analysis. Hubble runs live moderated interviews and full AI-moderated interviews from a discussion guide, with follow-ups and visual context from the participant's screen.

How does pricing compare?

Hubble lets you choose seat-based or study-based pricing, depending on how your team runs research. Userbrain publishes self-serve plans starting at $49 per month with a fixed number of panel testers, plus a custom Enterprise plan.

Does Hubble have its own participant panel?

Hubble connects directly to User Interviews and Respondent, so you can recruit consumer and B2B participants without leaving the platform. You can also recruit from your own users through the participant CRM or in-product surveys.

What can I do with Hubble's MCP?

Connect Claude, ChatGPT, Cursor or another MCP client to plan studies, publish them, recruit participants and analyze results, with you approving each change along the way.

How long does it take to switch from Userbrain?

Most teams launch their first study within days. We help you set up your workspace, recreate key templates and import your participant lists.
