Why Teams Choose Litmusly
The simulation layer that catches what automated tests miss
Vision-Powered Audits
Our personas don't just read code—they see your UI. Gemini Vision integration catches visual hierarchy issues, content gaps, and navigation problems that text-only agents miss.
A Library of Perspectives
A curated set of personas (a skeptical first-time visitor, a non-technical buyer, an accessibility-dependent engineer, and more) each reviews your preview from its own priorities, so different classes of friction surface at once.
Fast Feedback
No scheduling, no recruiting, no waiting. A review comment lands on your PR in about four minutes, so you can catch UX friction while the change is still fresh.
CI/CD Integration
Native GitHub App plus preview-deployment discovery via GitHub Deployments. Review results appear as a PR comment, making UX quality part of your merge workflow.
Review Every PR
No scheduling, no recruiting. Every pull request gets a persona review automatically, so UX regressions surface before they merge instead of after they ship.
Evidence-Based Findings
Each finding is tagged blocker, friction, or nit and grounded in the persona's walk of your preview, so you can triage what to fix before merge.
Don't Ship UX Debt
Every pull request gets an evidence report. Catch friction before it reaches production.
