Choose Spider Cloud if your priority is feeding high-quality, real-time web data into RAG pipelines or AI agents—its Rust engine and pay-per-page model make it unbeatable for scale. Choose Raindrop if you are running AI agents in production and need to detect silent failures, debug with trajectories, and auto-heal issues; its self-healing and triage features are unique. They are complementary: you could use Spider Cloud to fetch data and Raindrop to monitor the agent using that data.
