Frequently Asked Questions

Logic, Inc. vs Spider Cloud: which should you choose?

If your priority is building compliant, version-controlled AI agents with minimal engineering overhead, Logic is the clear choice—especially for healthcare or regulated workflows. If you need fast, affordable web data extraction to feed AI agents or RAG pipelines, Spider Cloud delivers unmatched performance and flexibility. Choose based on whether you’re building the agent or feeding it data.

Can I use Logic to scrape websites?

Logic includes web research and PDF form filling features, but it is not a dedicated scraping API. For high-volume or complex crawling, Spider Cloud is a better fit.

Does Spider Cloud support HIPAA compliance?

No, Spider Cloud does not offer SOC 2 or HIPAA certifications. If compliance is required, Logic should be used with a BAA.

Can Logic run on-premise?

As of July 2026, Logic is cloud-only. Spider Cloud offers an open-source self-hosted option.

How does pricing scale for high-volume usage?

Logic uses per-seat subscription tiers; Spider Cloud charges per page crawled ($0.03/1k pages). At very high volumes, Spider Cloud is cheaper, but Logic includes more features per seat.

Which tool integrates with LangChain?

Spider Cloud has native LangChain and LlamaIndex integrations. Logic integrates with OpenAI, Anthropic, Google, and Perplexity, but not directly with LangChain—use its REST API instead.

Do both tools support team collaboration?

Logic offers approval workflows and immutable versioning for team-based spec editing. Spider Cloud is API-focused; team collaboration extends via data connectors and sharing credentials.

Can I test my agents before deployment?

Logic automatically generates synthetic tests on every spec save, with rollback on failure. Spider Cloud does not provide testing; you must validate extracted data yourself.

Which is better for building a chatbot?

Neither is ideal. Logic is for structured agent tasks, not simple Q&A chatbots. Spider Cloud is for data extraction. For chatbots, consider a dedicated platform.
