Feature-by-feature

Spider Cloud focuses on raw web data extraction at scale: it crawls 100K+ pages per second, outputs markdown/JSON/screenshots, and includes anti-bot bypass. It also offers AI extraction with schema enforcement, data connectors to cloud storage (S3, GCS), and integrates with AI frameworks like LangChain, LlamaIndex, and CrewAI. Looker, in contrast, is about governed business intelligence: its core is LookML, a semantic modeling language that ensures consistent metrics, and it now adds Gemini AI agents for conversational analytics, dashboard summaries, and natural-language querying. Looker also supports embedded analytics via APIs/SDKs and seamless BigQuery integration. While Spider Cloud is built for high-throughput, unstructured-to-structured data pipelines, Looker is designed for metric governance and self-service analytics within large enterprises. There is no overlap in features; they solve different problems entirely.

Pricing compared

Spider Cloud uses a pay-as-you-go credit model with no published tiers, charging per page crawled (with relevance gating to avoid wasted credits). It also offers an open-source MIT-licensed engine for self-hosting, appealing to developers who want to control costs or avoid cloud dependency. Looker requires contacting sales for pricing, typical for enterprise BI platforms; costs scale with usage (number of users, queries, storage). Looker does not have a free tier, while Spider Cloud likely has a free tier for limited usage (not explicitly stated but common among API services). For a small AI project, Spider Cloud's pay-as-you-go model is cost-effective; for an enterprise with hundreds of users needing governed BI, Looker's enterprise pricing is appropriate.
