Usability testing with real users, right from your coding agent
Hallway Test is a usability testing MCP for Claude Code, Cursor and Codex. Your agent sends a flow to a fresh person, and the recording, think-aloud transcript and friction points come back within 24 hours, ready to fix.
- We never see your code
- Full MCP control
- Real human test

What pilot teams found with a real user

“We’re a small team, and it’s easy to miss things in a flow we work with every day. The test caught translation issues we’re already fixing.”
Before opening registration more widely, Spevdo tested its website with a fresh user. The session surfaced translation issues, and the co-founders have already started working on a fix.

“We identified several critical friction points where users either got completely stuck, such as during registration, or became lost within large menus.”
We’re tweaking the UI on the registration form, as well as the profile page and the post-creation flow.

“Sometimes I feel it’s not getting enough feedback from a more professional eye, rather than hypothetical friends, or my acquaintance engineers, but a more professional look at my products, at what could be improved, is extremely valuable.”
The respondent recommends the service when a fresh perspective is needed.

Questions, answered
Everything you'd ask before letting a real user loose on your product.
Hallway Test is an MCP server your coding agent can call directly. Point it at whatever you just shipped and a real user tries it – no synthetic panels, no other model guessing on your behalf.
A model can flag obvious issues, but it can't get confused, hesitate, or misread a button the way a real user does. Hallway Test swaps that guess for a real user going through your flow on camera.
A screen- and voice-recorded session, a full transcript and a log of every click, delivered straight into your agent's context. Your agent turns them into timestamped friction points, ready to act on.
No – describe the flow in a sentence, like “place an order as a guest and reach confirmation.” Hallway Test briefs the real user like a real hallway test, not a rigid QA script.
Results come back within 24 hours – you can watch status update live in your agent's task list while it runs.
Yes, for React Native and Expo apps on iOS and Android. Add the Hallway Test SDK and record sessions of your own app: screen, voice, taps, screens, network requests, logs and crashes. Your coding agent then audits the recording through MCP. The first 10 recordings are free.
Hallway Test ships as a standard MCP server, so it works with Claude Code and any other MCP-compatible agent today, with more integrations on the way.
