About firecrawl

A skill for using the Firecrawl CLI to search, scrape, crawl, and interact with websites, with results organized for LLM workflows. It guides developers through choosing an extraction method and handling outputs.

Key features

  1. 01Search and scrape web pages
  2. 02Map URLs and crawl site sections
  3. 03Extract structured data with agent
  4. 04Interact with pages using browser
  5. 05Download websites to local files
  6. 06Save and organize command outputs

Use cases

  1. 01Finding and collecting sources on a topic
  2. 02Extracting content from a known page
  3. 03Gathering documentation across a site section
  4. 04Retrieving information behind interactive page elements

Install

Copy the command and run it in a terminal.

Details

From the project README

Firecrawl CLI

Web scraping, search, and browser automation CLI. Returns clean markdown optimized for LLM context windows.

Run firecrawl --help or firecrawl <command> --help for full option details.

Prerequisites

Must be installed and authenticated. Check with firecrawl --status.

  🔥 firecrawl cli v1.8.0

  ● Authenticated via FIRECRAWL_API_KEY
  Concurrency: 0/100 jobs (parallel scrape limit)
  Credits: 500,000 remaining
  • Concurrency: Max parallel jobs. Run parallel operations up to this limit.
  • Credits: Remaining API credits. Each scrape/crawl consumes credits.

If not ready, see rules/install.md. For output handling guidelines, see rules/security.md.

firecrawl search "query" --scrape --limit 3

Workflow

Follow this escalation pattern:

  1. Search - No specific URL yet. Find pages, answer questions, discover sources.
  2. Scrape - Have a URL. Extract its content directly.
  3. Map + Scrape - Large site or need a specific subpage. Use map --search to find the right URL, then scrape it.
  4. Crawl - Need bulk content from an entire site section (e.g., all /docs/).
  5. Browser - Scrape failed because content is behind interaction (pagination, modals, form submissions, multi-step navigation).

For detailed command reference, use the individual skill for each command (e.g., firecrawl-search, firecrawl-browser) or run firecrawl <command> --help.

Scrape vs browser:

  • Use scrape first. It handles static pages and JS-rendered SPAs.
  • Use browser when you need to interact with a page, such as clicking buttons, filling out forms, navigating through a complex site, infinite scroll, or when scrape fails to grab all the content you need.
  • Never use browser for web searches - use search instead.

Avoid redundant fetches:

  • search --scrape already fetches full page content. Don't re-scrape those URLs.
  • Check .firecrawl/ for existing data before fetching again.

Output & Organization

Unless the user specifies to return in context, write results to .firecrawl/ with -o. Add .firecrawl/ to .gitignore. Always quote URLs - shell interprets ? and & as special characters.

firecrawl search "react hooks" -o .firecrawl/search-react-hooks.json --json
firecrawl scrape "<url>" -o .firecrawl/page.md

Naming conventions:

.firecrawl/search-{query}.json
.firecrawl/search-{query}-scraped.json
.firecrawl/{site}-{path}.md

Never read entire output files at once. Use grep, head, or incremental reads:

wc -l .firecrawl/file.md && head -50 .firecrawl/file.md
grep -n "keyword" .firecrawl/file.md

Single format outputs raw content. Multiple formats (e.g., --format markdown,links) output JSON.

Working with Results

These patterns are useful when working with file-based output (-o flag) for complex tasks:

# Extract URLs from search
jq -r '.data.web[].url' .firecrawl/search.json

# Get titles and URLs
jq -r '.data.web[] | "\(.title): \(.url)"' .firecrawl/search.json

Parallelization

Run independent operations in parallel. Check firecrawl --status for concurrency limit:

firecrawl scrape "<url-1>" -o .firecrawl/1.md &
firecrawl scrape "<url-2>" -o .firecrawl/2.md &
firecrawl scrape "<url-3>" -o .firecrawl/3.md &
wait

For browser, launch separate sessions for independent tasks and operate them in parallel via --session <id>.

Credit Usage

firecrawl credit-usage --json --pretty -o .firecrawl/credits.json
