| Billing Architecture | usage based | usage based |
| Developer Free Tier | ✓ Yes Free trial credits for developers | ✓ Yes 3 shared-cpu-1x microVMs allowance |
| Entry Paid Tier (Monthly) | $15 USD / mo | $1.94 USD / mo |
| Pricing & Cost Architecture | Pay-as-you-go starts at $0/mo commitment ($1.50 per 1,000 page loads or $8.40/GB residential proxy). Growth subscriptions start at $499/mo for high-volume enterprise scraping. | Pay-as-you-go billed per second: shared CPU microVMs start at ~$0.0000022/second (~$1.94/month if running 24/7). Stopped machines pay only for attached NVMe disk storage ($0.15/GB/mo). |
| Key Engineering Insight | Operates one of the world's largest peer-to-peer residential proxy networks with over 72 million ethically sourced IPs across 195 countries. | Operates custom bare-metal servers across 35+ global edge datacenters, booting Linux kernels directly on KVM without container orchestration overhead. |
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
Fly Machines Evaluation
Key Advantages
- ✓ Sub-300ms boot times for custom Docker images running in 35+ global edge data centers close to end users
- ✓ Full persistent NVMe volume support with customizable memory/vCPU ratios per individual machine instance
- ✓ Fast REST API allowing agents to dynamically spawn, pause, snapshot, and destroy microVMs programmatically
Limitations & Trade-Offs
- ✕ Requires managing base Linux Docker images, security firewall configurations, and internal WireGuard routing
- ✕ Lacks a specialized high-level code execution SDK out of the box (requires building custom API wrappers)
