It reads `sitemap.xml` (including nested sitemaps), then falls back to link extraction from the seed page. Use it to plan a crawl, audit a site's surface, or feed a URL list into another tool. ## Quick recipe ```bash crawlberg map https://example.com --limit 500 --search docs --format markdown ``` Markdown output prints one URL per line — convenient to pipe into a file or a follow-up `crawl`. JSON output (default) returns a structured `MapResult`. ## Flag surface | Flag | Default | Purpose | | ---------------------- | ------- | ------------------------------------------------------------- | | `--limit` | — | Maximum number of URLs to return. Unbounded if unset. | | `--search` | — | Case-insensitive substring filter on discovered URLs. | | `--respect-robots-txt` | off | Honour `robots.txt`. Pass it for any third-party host. | | `--format` | `json` | `json` (full `MapResult`) or `markdown` (one URL per line). | | `--timeout` | `30000` | Per-request timeout in ms. | | `--browser-mode` | `auto` | `auto`, `always`, `never` — see the headless-fallback skill. | | `--browser-endpoint` | — | External CDP `ws://` URL. | | `--config` | — | Inline JSON or `@file.json` for the full `CrawlConfig`. | `map` takes a single seed URL positionally. There is no `--depth` or `--max-pages` here — those bound a `crawl`, not a map. Scope is the seed host's sitemaps plus links found on the seed page; bound the result with `--limit` and narrow it with `--search`. ## How discovery works 1. Fetch and parse `sitemap.xml`, following nested `<sitemapindex>` entries. 2. If no sitemap (or a thin one), extract links from the seed page's HTML. 3. Apply the `--search` substring filter (case-insensitive), then `--limit`. No page bodies are rendered, so a map of hundreds of URLs returns in seconds — far cheaper than crawling. In `--browser-mode auto` the seed fetch still falls back to headless Chrome if the seed page is a JS shell that hides its links; pass `--browser-mode never` to keep it static-only. ## Output ### Markdown mode ```text https://example.com/ https://example.com/docs/ https://example.com/docs/getting-started https://example.com/blog/post-one ``` ### JSON mode Top-level `MapResult` with a `urls` array; each entry carries the discovered `url`. Read `result.urls[i].url` for each string when scripting. ```bash crawlberg map https://example.com --format json | jq -r '.urls[].url' ``` ## Common patterns ### Discover then crawl a subsection ```bash crawlberg map https://example.com --search /docs/ --format markdown > urls.txt ``` Feed the filtered list into a bounded crawl, or scrape individual entries. ### Audit a third-party site politely ```bash crawlberg map https://unknown.example --respect-robots-txt --limit 200 ``` ## When to reach for crawl instead If the user needs the page *content* (Markdown, metadata, tables) rather than just the URL list, use `crawlberg crawl` — see the `crawling-a-site` skill. Reach for `map` first when the goal is enumeration, planning, or seeding.
