| Technical Feature / Metric | Astra DB | Scrapfly |
|---|---|---|
| Developer / Organization | DataStax Inc. | Scrapfly SAS |
| Open-Source Engine | ✓ Open Source (Apache-2.0) | ✕ Proprietary Cloud |
| GitHub Stars (Repo/SDK) | ★ 30 GitHub Stars | Proprietary / Closed Core |
| Core Repository Language | TypeScript | Cloud API |
| Supported SDK Clients | ||
| Self-Hosted Deployment | Hosted Only | Hosted Only |
| Docker / Container Ready | ✓ Official Image | Managed |
| Model Context Protocol (MCP) | ✓ Native MCP | ✓ Native MCP |
| Billing Architecture | usage based | usage based |
| Developer Free Tier | ✓ Yes $25/mo free serverless credit (~80GB storage) | ✓ Yes 1,000 free API credits |
| Entry Paid Tier (Monthly) | $25 USD / mo | $30 USD / mo |
| Pricing & Cost Architecture | Free tier provides 80GB monthly data transfer and 25M read/write operations (~$25/mo value). Pay-as-you-go serverless scales from $0 based on actual operations and storage. | 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). |
| Key Engineering Insight | Powered by JVector, a pure Java vector search engine developed by DataStax that outperforms Lucene HNSW by using DiskANN-inspired graph indexing. | Uses custom-patched Chromium instances to mimic real residential JA3/TLS browser fingerprints, bypassing Cloudflare Turnstile and DataDome automatically. |
Strengths & Trade-Offs
Objective engineering evaluation of both platforms
Astra DB Evaluation
Key Advantages
- ✓ Built on Apache Cassandra: enterprise reliability, active-active multi-region replication, and zero downtime
- ✓ JVector DiskANN index engine achieves higher recall and faster searches while storing vectors on SSD disk
- ✓ Includes intuitive JSON Data API (Clojure-inspired) and native LangChain / LlamaIndex integrations
Limitations & Trade-Offs
- ✕ Serverless pricing can scale with heavy multi-tenant indexing and continuous vector updates
- ✕ Closed-source managed cloud tier (although underlying Apache Cassandra and JVector are open source)
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
