Entry Paid Tier (Monthly) $16 USD / mo $190 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. 100% Free open-source engine (Apache-2.0) for self-hosting via Docker. Vespa Cloud managed clusters start at ~$0.26/hour (~$190/mo) with free trial credits.
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. Originally engineered by Yahoo to serve billions of real-time queries per day; evaluates machine-learned ranking models (ONNX/XGBoost) directly inside the storage nodes.

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

Vespa Evaluation

Key Advantages

  • ✓ Evaluates custom ML ranking models (ONNX, ColBERT, cross-encoders) directly inside storage nodes in real time
  • ✓ Proven enterprise scale: handles tens of billions of vectors and hundreds of thousands of queries per second
  • ✓ True hybrid search: merges BM25, vector ANN, and structured relational filters in a single execution phase

Limitations & Trade-Offs

  • ✕ Steep operational learning curve and complex XML/YML application package schema definitions
  • ✕ High hardware resource footprint compared to lightweight single-binary vector stores
