Cons

Credit-based pricing can get expensive for high-volume use
Reliance on third-party service may introduce latency for real-time apps
Advanced features (Premium Proxy) require additional cost
Not ideal for teams needing full infrastructure control

Decision Guidance

When to use: Need large-scale scraping of protected sites (e-commerce, travel, SERPs), real-time data for AI applications, or want to avoid building proxy infrastructure. Ideal for price monitoring, lead generation, and market research.

Consider alternatives: If budget is tight with low scraping volume, need full control over proxy servers, or target sites lack anti-bot protection, consider self-hosted solutions or open-source tools.
