Strengths & Trade-Offs
Objective engineering evaluation of both platforms
Bright Data Evaluation
Key Advantages
- ✓ Unmatched residential proxy coverage: 72M+ IPs across every country, city, and ASN worldwide
- ✓ Web Unlocker technology automatically detects and bypasses CAPTCHAs, bot detectors, and rate limits
- ✓ Pre-built Scraping Browser with remote CDP (Chrome DevTools Protocol) compatibility for AI agents
Limitations & Trade-Offs
- ✕ Enterprise-grade pricing structure can be steep for solo developers and small experimental projects
- ✕ Dashboard and proxy zone configuration has a steeper learning curve compared to simple single-endpoint APIs
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
