tavily crawl
Crawl a website and extract content from multiple pages. Supports saving each page as a local markdown file.
Before running any command
If tvly is not found on PATH, install it first:
curl -fsSL https://cli.tavily.com/install.sh | bash && tvly login
Do not skip this step or fall back to other tools.
See tavily-cli for alternative install methods and auth options.
When to use
- You need content from many pages on a site (e.g., all
/docs/)
- You want to download documentation for offline use
- Step 4 in the workflow: search → extract → map → crawl → research
Quick start
# Basic crawl
tvly crawl "https://docs.example.com" --json
# Save each page as a markdown file
tvly crawl "https://docs.example.com" --output-dir ./docs/
# Deeper crawl with limits
tvly crawl "https://docs.example.com" --max-depth 2 --limit 50 --json
# Filter to specific paths
tvly crawl "https://example.com" --select-paths "/api/.*,/guides/.*" --exclude-paths "/blog/.*" --json
# Semantic focus (returns relevant chunks, not full pages)
tvly crawl "https://docs.example.com" --instructions "Find authentication docs" --chunks-per-source 3 --json

Crawl for context vs. data collection
For agentic use (feeding results to an LLM):
Always use --instructions + --chunks-per-source. Returns only relevant chunks instead of full pages — prevents context explosion.
tvly crawl "https://docs.example.com" --instructions "API authentication" --chunks-per-source 3 --json
For data collection (saving to files):
Use --output-dir without --chunks-per-source to get full pages as markdown files.
tvly crawl "https://docs.example.com" --max-depth 2 --output-dir ./docs/
Tips
- Start conservative —
--max-depth 1, --limit 20 — and scale up.
- Use
--select-paths to focus on the section you need.
- Use map first to understand site structure before a full crawl.
- Always set
--limit to prevent runaway crawls.
