Entry Paid Tier (Monthly) $30 USD / mo $25 USD / mo
Pricing & Cost Architecture Free trial provides 1,000 initial API credits. Discovery plan starts at $30/mo for 200,000 API credits (basic request = 1 credit; JS rendering + residential proxy = 5-25 credits). Core engine is 100% free under BSD-3-Clause. Weaviate Cloud (WCD) provides a 14-day free sandbox, with serverless consumption tiers starting at $0.05 per 1,000 queries.
Key Engineering Insight Uses custom-patched Chromium instances to mimic real residential JA3/TLS browser fingerprints, bypassing Cloudflare Turnstile and DataDome automatically. Pioneered native Hybrid Search in vector databases, allowing developers to mathematically merge sparse BM25 keyword matching with dense HNSW vector similarity in one call.

Strengths & Trade-Offs

Objective engineering evaluation of both platforms

Scrapfly Evaluation

Key Advantages

  • ✓ Advanced Anti-Scraping Protection (ASP) with automated residential proxy rotation and CAPTCHA solving
  • ✓ Direct markdown format extraction parameter (&format=markdown) built specifically for LLM ingestion
  • ✓ Full JavaScript rendering engine supporting custom pre-scrape evaluate scripts and scroll triggers

Limitations & Trade-Offs

  • ✕ Advanced proxy and headless browser features consume between 5 and 25 API credits per request
  • ✕ Strictly cloud-hosted API; no on-premise Docker deployment option

Weaviate Evaluation

Key Advantages

  • ✓ Native Hybrid Search seamlessly merging sparse BM25 keyword scoring with dense vector cosine distance
  • ✓ Modular architecture supporting direct vectorization with OpenAI, Cohere, HuggingFace, and local Ollama models
  • ✓ Rich GraphQL and RESTful APIs with flexible schema definitions and built-in multi-tenancy support

Limitations & Trade-Offs

  • ✕ Higher baseline RAM utilization due to concurrently maintaining inverted text indexes and vector graphs
  • ✕ Configuring external vectorizer microservice containers adds operational moving parts when self-hosting
