Testerloop — UI experience regression checks

Automated front-end testing for layout, interaction, and UX details, not just clicks

Problem

Most front-end automation only covers functional paths, while what users actually feel is layout, interaction feedback, and visual consistency. Someone explicitly asked for tools that test UI layout and user experience automatically, showing that current options are either functional or screenshot-diff based and miss the fuzzy but important experience layer.

Solution

An AI-driven inspection tool for front-end teams: configure key pages and viewports, then it screenshots and analyzes layout misalignment, overlapping elements, text overflow, and unclickable buttons, returning an annotated report. Users can express expectations in natural language, e.g. 'this button should always be visible on mobile', and the tool rechecks on every build.

Users

Front-end teams, indie developers, and design reviewers, especially small teams without dedicated QA but with high UI standards

MVP

Configure page URLs and viewport list; auto-screenshot and detect overlap, overflow, and invisible elements; natural-language expectations with periodic rechecks; annotated report posted to PR comments; GitHub Actions integration

Revenue

Per-project or monthly subscription with free tier limited by page count and check frequency; API for CI integration

Why now

Multimodal models can now understand layout and interaction issues from screenshots; front-end teams worry about experience regressions but lack a cheap, good tool
