Bring clarity to Bun test coverage reports.
Bun only outputs plain text and lcov numbers. BunCover turns that raw data into an interactive dashboard that highlights which lines are covered, what still needs tests, and how your suite is trending over time.
Visual coverage overlays
See uncovered lines inline with your source code.
AI-powered test prompts
Generate missing tests directly from coverage gaps.
Trend-aware dashboards
Track how every project improves across releases.

Your Source Code is Safe
We prioritize your privacy and security
Source Code Privacy
We want to be clear: we do not store any source code from your repository on our servers. When you use the BunCover CLI to upload coverage reports, source code data is transmitted to display coverage overlays in real-time on the frontend. However, this source code data is processed in real-time and displayed directly to you without being persisted to our database. BunCover only stores coverage metrics, line-level coverage information, and file paths. Your actual source code remains completely private and secure.
