Gerrit Code Review Extractor

Point at any Gerrit code-review server and get clean, structured rows — one per change (code review), project, or server. Gerrit is the self-hosted code-review server behind Android, Chromium, and Go, and adopted by OpenStack, Wikimedia, ONAP, LineageOS, Eclipse, GerritHub and countless corporate and university deployments. Every Gerrit speaks the identical REST API and leaves anonymous read on for public projects, so this one actor works against all of them — no per-server scraper, no login.

What it does

Three modes, chosen by the Run mode field:

• changes (default) — one row per code-review change matching your query (status:open by default). Columns: project, change number, subject, status, owner, branch, insertions/deletions, comment counts, work-in-progress flag, and (with options) review labels, a submit-label summary, and message counts.
• projects — the server's project/repository inventory, one row per project (name, state, parent, description).
• server — one row per server describing its version and authentication model.

Point it at several servers at once and it runs each in turn; a URL that isn't a Gerrit (a login page, or a host that migrated to GitLab/Gitea) is skipped with a warning instead of failing the whole run.

Example input

{
  "sources": ["https://review.opendev.org"],
  "mode": "changes",
  "query": "status:open",
  "options": ["LABELS", "DETAILED_ACCOUNTS"],
  "maxRecords": 20
}

Other ready-to-run servers: https://review.gerrithub.io (GerritHub), https://gerrit.onap.org, https://gerrit.osmocom.org, and any self-hosted instance. Some servers sit at a /r mount (https://gerrit.wikimedia.org) — paste either form, the /r path is auto-detected.

Note on datacenter IPs. A few very large Google-hosted servers (android-review, chromium-review, go-review on googlesource.com) and some others block datacenter IP ranges, so they respond from a laptop but not from a cloud datacenter. When running on the platform, prefer an independent server such as review.opendev.org, or supply auth for a gated one.

Query examples (changes mode)

• status:open — all open changes
• status:merged — recently merged changes
• project:platform/frameworks/base status:open — one project's open changes
• owner:self status:open — (with auth) your own open changes
• after:2026-01-01 status:merged — merged since a date
• is:wip — work-in-progress changes

Output

One flat row per record. Change rows carry

_type/_source/_mode/_software/ _serverVersion

Pricing

Pay-per-event: one record charge per emitted row. The ready-to-run default targets OpenDev and caps the first run at 20 rows; raise maxRecords deliberately for larger exports.

Notes

• Anonymous read is used by default. For a private or rate-limited server you may supply a bearer token, a cookie, or extraHeaders — these are never logged and are never required for public data.
• The actor reads every field by key presence, so servers on different Gerrit versions (which populate different optional fields) all work without error.
