| Developer Free Tier | ✓ Yes 20 RPM free without registration or API key | ✓ Yes 500MB database storage (2 free projects) |
| Entry Paid Tier (Monthly) | $10 USD / mo | $25 USD / mo |
| Pricing & Cost Architecture | 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. | Free tier offers 2 managed projects with 500MB database storage (~250k vectors). Pro plan starts at $25/mo with 8GB storage and scalable compute add-ons. |
| Key Engineering Insight | 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. | Allows developers to store relational application state, user authentication (Row Level Security), and high-dimensional vector embeddings inside a single ACID-compliant Postgres database. |
Strengths & Trade-Offs
Objective engineering evaluation of both platforms
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
Supabase Vector Evaluation
Key Advantages
- ✓ Combines vector search with full Postgres ecosystem: Row Level Security, ACID transactions, and relational joins
- ✓ Instant auto-generated client APIs (REST, GraphQL, real-time WebSockets) with zero backend boilerplate
- ✓ Permissive open-source stack with official Docker compose deployment for self-hosting on any VPS
Limitations & Trade-Offs
- ✕ Free tier projects pause automatically after 7 days of inactivity (resumed upon dashboard login)
- ✕ Dedicated standalone C++ vector stores can achieve higher raw QPS for multi-million vector datasets
