Frequently Asked Questions
Should I use Browser-Use, Crawl4AI, or Firecrawl in 2026?
Use Crawl4AI or Firecrawl when your goal is high-speed RAG ingestion that turns URLs into clean Markdown (-96% tokens). Use Browser-Use or Stagehand when your agent must click buttons, fill forms, and navigate authenticated multi-step workflows.
How much LLM token spend does Fit-Markdown pruning save?
Feeding raw HTML DOMs averages 42,000 tokens per page ($3,150/mo at 500k pages). Pruning boilerplate DOM nodes into Fit-Markdown via Crawl4AI or Firecrawl drops payload size to 1,680 tokens/page ($126/mo), saving 96.0%.
