Maintainers

This page maps subsystems to the people most likely to know them. The data comes from git log against the local checkout (commit 18ab0f95, branch master); the project does not have a CODEOWNERS file at the repo root, so all signals are derived from history.

The Caddy project's mainline maintenance is led by Matthew Holt (the author and creator); many parts of the codebase have Francis Lavoie as the most active recent collaborator. The table below shows the top 2–3 historical committers per area.

Notes

• Bot accounts (e.g. dependabot[bot]) are excluded — they are not people you can ask questions of.
• The codebase has had 389 unique contributors over its history. Many components have meaningful contributions from people not listed here; the table is intentionally short.
• Use git log --since=… -- <path> for fresher per-file data; the table above reflects all-time signal, weighted toward authors with sustained activity.
