netlify logs adds the server log source

Introduced 2026-10-27 · score 0.98

HOW TO USE IT

When debugging an application, read Netlify Server logs with `netlify logs --source server`; limit history with `--since 30m` or stream new lines with `--follow`.

WHY THIS HELPS

Inspect Netlify Server logs while debugging an application.

BEFORE THIS CHANGE

`netlify logs` had no way to read Netlify Server logs.

REQUIREMENTS AND LIMITATIONS

• Version: 27.15.0
• Non-interactive: `--json` outputs logs as JSON Lines.
• --source: Log sources; defaults to functions and edge-functions.
• --since: Historical window start; accepts duration or ISO 8601; defaults to 10m.
• --follow: Stream logs instead of showing historical logs.
• --json: Output logs as JSON Lines.
• `--deploy-id` and `--url` are rejected with `--source server`, because server logs are not tied to a deploy.
• History paging stops 10,500 lines back; when that cuts the window short, the command warns on stderr, including with `--json`.
• `--follow` polls every 2 seconds with a 10-second look-back and prints only lines it has not printed yet. It stops on a 401, 403, or 404; it reports other failures without stopping.
