Health Reports

Codebase health, tracked over time

Dev Herald snapshots your repo health from CI and compares each report against the last one — so your team can spot new CVEs, bundle regressions, dependency growth, and cleanup opportunities before they pile up.

Not just a weekly Slack message. A history of what changed, why it matters, and what to do next.

Step 1

Snapshot every report

Capture dependencies, vulnerabilities, bundle size, unused files, unused exports, and cleanup metrics from CI.

Step 2

Compare what changed

See the difference from the previous snapshot — new risks, regressions, improvements, and trends.

Step 3

Act from the report

Send Slack summaries, open GitHub issues, copy cleanup prompts, or use MCP to drive automated cleanup workflows.

Free for open source projects

Maintaining open source is hard enough already.

Dev Herald helps reduce the busywork around pull requests, project health, and release notes — so maintainers can spend more time on the code, and less time repeating themselves.

Public repositories get automated PR comments, health reports, and AI release notes for free.

No credit card required.
