Pale, doughy, and a touch sad. Eat if peckish.
Summary
Long Horizon is a tool that extends AI coding agents to also handle testing. As coding agents write most code, the bottleneck has shifted from building features to testing and reviewing them. Long Horizon runs real browser tests and produces shareable execution reports with logs, screenshots, and network details, enabling confident feature delivery without manual testing overhead.
