| Key Engineering Insight | Graduated as a top-tier open-source project under the Linux Foundation (LF AI & Data); powers similarity search across collections exceeding tens of billions of embeddings in Fortune 500 banks. | 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
Milvus Evaluation
Key Advantages
- ✓ Engineered specifically for massive enterprise scale: partitions and queries billions of high-dimensional vectors
- ✓ Disaggregated storage-and-compute architecture leveraging cloud object storage (S3/MinIO) and message brokers
- ✓ Hardware-accelerated indexing with GPU support (cuVS / RAFT) for rapid index construction on massive datasets
Limitations & Trade-Offs
- ✕ High deployment and operational complexity: distributed mode requires Kubernetes, etcd, Pulsar/Kafka, and MinIO
- ✕ Substantial architectural overhead for lightweight single-agent prototypes with fewer than 500,000 vectors
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
