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.

Snapshot every report
Capture dependencies, vulnerabilities, bundle size, unused files, unused exports, and cleanup metrics from CI.
Compare what changed
See the difference from the previous snapshot — new risks, regressions, improvements, and trends.
Act from the report
Send Slack summaries, open GitHub issues, copy cleanup prompts, or use MCP to drive automated cleanup workflows.
