About
Long Horizon is an agentic frontend testing platform that integrates with AI coding agents to automatically plan, author, and execute browser-based tests. It provides complete execution logs, screenshots, and network details in shareable reports to support confident code review and feature delivery. The tool supports debugging workflows and PR review processes by giving developers evidence-backed test results.
Problem
AI coding agents can write features quickly but lack integrated test planning and execution, leaving developers without confidence that features work correctly before review.
