Entry Paid Tier (Monthly) $16 USD / mo $15 USD / mo
Pricing & Cost Architecture Monthly credit quota: Free tier provides 500 scrape credits/mo (1 page = 1 credit; 1 crawl = 1 credit per discovered page). Starter plan is $16/mo for 3,000 credits ($0.0053/page). Growth is $99/mo for 100,000 credits. Core Rust crawler is 100% free and open-source under MPL-2.0. Managed Spider Cloud API offers a free tier of 1,000 credits, with paid plans beginning at $15/mo.
Key Engineering Insight Created after developers struggled with fragile Puppeteer scripts for RAG; its scraping cluster processes millions of web pages weekly with automated proxy rotation and stealth headers. Independent benchmarks demonstrate Spider crawling large e-commerce catalogs at over 100,000 pages per minute while maintaining RAM consumption under 150MB.

Strengths & Trade-Offs

Objective engineering evaluation of both platforms

Firecrawl Evaluation

Key Advantages

  • ✓ Converts complex JavaScript-rendered SPAs and shadow DOM into clean, structured markdown optimized for LLM tokenization
  • ✓ Includes built-in automated anti-bot bypass, residential IP rotation, and captcha handling with no external proxy configuration
  • ✓ Official Model Context Protocol (MCP) server support and official SDKs for Python and TypeScript

Limitations & Trade-Offs

  • ✕ AGPL-3.0 copyleft license requires open-sourcing modifications when self-hosting in proprietary environments
  • ✕ Credit consumption scales rapidly on deep recursive crawls across multi-page domains

Spider Evaluation

Key Advantages

  • ✓ High-performance Rust architecture delivering benchmark speeds up to 10x faster than Python Scrapy
  • ✓ Minimal CPU and RAM footprint allowing dense deployment on lightweight VPS instances or containers
  • ✓ Permissive Mozilla Public License 2.0 open-source engine with built-in headless browser and HTTP modes

Limitations & Trade-Offs

  • ✕ Smaller developer community and fewer pre-built third-party plugins compared to Playwright or Puppeteer
  • ✕ Extending low-level network and HTML parsing logic requires proficiency with the Rust toolchain
