Zaplens
Find your UX bugs before your users do
Zaplens runs synthetic UX tests with 100+ AI personas to show where users click, hesitate, and bounce. In about 90 seconds, it generates multi-channel heatmaps—attention, confusion, attraction, and repulsion—plus a plain-English report with prioritized fixes. You can import custom personas, compare v1 vs v2 in Battle mode, and stream agent reasoning in real time. Plans range from free to enterprise, and an MCP integration lets you launch and summarize runs from your AI assistant.
