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:

• Search - No specific URL yet. Find pages, answer questions, discover sources.

• Scrape - Have a URL. Extract its content directly.

• Map + Scrape - Large site or need a specific subpage. Use map --search to find the right URL, then scrape it.

• Crawl - Need bulk content from an entire site section (e.g., all /docs/).

• Browser - Scrape failed because content is behind interaction (pagination, modals, form submissions, multi-step navigation).

Need Command When

Find pages on a topic search No specific URL yet

Get a page's content scrape Have a URL, page is static or JS-rendered

Find URLs within a site map Need to locate a specific subpage

Bulk extract a site section crawl Need many pages (e.g., all /docs/)

AI-powered data extraction agent Need structured data from complex sites

Interact with a page browser Content requires clicks, form fills, pagination, or login

Download a site to files download Save an entire site as local files

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