Entry Paid Tier (Monthly) $5 USD / mo $10 USD / mo
Pricing & Cost Architecture Free tier includes 30 million queried vector dimensions and 5 million stored vector dimensions per month. Paid Workers plan ($5/mo base) bills $0.01 per 1M queried dimensions. Standard web reader endpoint is 100% free with a rate limit of 20 requests per minute without an API key. Token-based API access for high concurrency begins at $10 for 10 million tokens.
Key Engineering Insight Runs directly on Cloudflare's 300+ global edge data centers alongside Workers AI, eliminating cross-cloud network roundtrips during RAG retrieval. Created by former Tencent AI lead Dr. Han Xiao; prepending 'https://r.jina.ai/' to any public URL immediately parses the page into markdown with zero API key or registration required.

Strengths & Trade-Offs

Objective engineering evaluation of both platforms

Cloudflare Vectorize Evaluation

Key Advantages

  • ✓ Zero cold-start edge execution: queries execute within milliseconds in 300+ global data centers
  • ✓ Co-located with Workers AI: run embeddings and vector lookups within the same edge runtime
  • ✓ Generous free tier allowing millions of dimensional queries every month at zero cost

Limitations & Trade-Offs

  • ✕ Maximum index size of 5 million vectors per index on standard plans (designed for distributed edge retrieval)
  • ✕ Requires building within or interfacing through the Cloudflare Workers ecosystem

Jina Reader Evaluation

Key Advantages

  • ✓ Zero setup required: simply prefixing 'https://r.jina.ai/' to any web URL returns sanitized markdown
  • ✓ Public endpoint is completely free and unauthenticated for AI developers and agent prototypes
  • ✓ Integrated web search grounding via 'https://s.jina.ai/' returning top Google/Bing results as tokenized markdown

Limitations & Trade-Offs

  • ✕ Free unauthenticated endpoint is rate-limited to 20 requests per minute per IP address
  • ✕ Stateless HTTP scraper that cannot interactively click custom buttons, submit forms, or solve complex manual CAPTCHAs
