Maintainers

The authoritative list is in OWNERS.md. The detailed per-directory ownership is in CODEOWNERS. This page summarises the structure.

Roles

Envoy distinguishes several maintenance roles, codified in GOVERNANCE.md:

Role	What they do
Senior maintainers	Final say across the project. Members of the security team. Typically full-time paid to work on Envoy.
Maintainers	Approve and merge PRs in their area. Take on-call rotations.
Senior extension maintainers	Final say over a specific extension family (Wasm, Golang, Thrift, JWT, gRPC-JSON).
Extension maintainers	Listed in CODEOWNERS per extension; review PRs to that extension.
Envoy Mobile maintainers	Final say over mobile/.
Envoy security team	Triage and embargo CVE reports.

Becoming a maintainer

GOVERNANCE.md describes the path:

1. Sustained, high-quality contributions over months.
2. Two existing maintainers nominate the candidate.
3. Two-thirds maintainer approval.
4. The new maintainer agrees to on-call rotations and review responsibilities.

There is no separate path to "extension maintainer" — every extension's CODEOWNERS row names two people who agreed to maintain it; they are listed by name and trusted to review PRs to that extension.

Conflict resolution and voting

Disputes that can't be resolved by reviewers go to a maintainer vote. Two-thirds majority decides. Decisions are documented in the relevant GitHub issue.

Security team

The security team triages CVE reports, coordinates embargoed fixes, and manages the disclosure process. The team includes all senior maintainers plus a wider rotation listed in OWNERS.md. Reports go to envoy-security@googlegroups.com per SECURITY.md.

Where to look up an extension's owner

Use CODEOWNERS — each row is a glob and a list of GitHub handles. PRs touching that path automatically request review from the listed handles.

Emeritus

OWNERS.md maintains an "Emeritus" section: past maintainers who shaped the project but are no longer active. Names there have done significant work on listeners (Antonio Vicente), HTTP plumbing (Alyssa Wilk), Lyft's mobile origin (JP Simard, Rafal Augustyniak, Michael Rebello, Alan Chiu), API design (Harvey Tuch), and stats (Joshua Marantz).

Friends of Envoy

A small group of subject-matter experts who aren't maintainers but help with reviews. Yuchen Dai (@lambdai) on xDS / listeners, Michael Payne (@moderation) on dependencies and docs, Cerek Hillen (@crockeo) on Python and C++ platform bindings.
