Frequently Asked Questions

Epsilla vs Spider Cloud: which should you choose?

For teams looking to build custom AI agents without coding, Epsilla is the better choice. But for AI pipelines that need live web data—scraping, crawling, and structured extraction—Spider Cloud is far more advanced, cheaper, and actively updated with Browser AI and data connectors. Pick Epsilla if you need a managed AI agent; pick Spider Cloud if you need web data for your AI.

Can I use Epsilla with models other than GPT-4?

Epsilla currently only lists OpenAI models (GPT-4, GPT-4.1) as integrations. It does not support Claude, Llama, or other providers out-of-the-box.

Does Spider Cloud support JavaScript rendering?

Yes, Spider Cloud's Browser Cloud includes a headless browser with stealth anti-detection, and Browser AI commands (Act, Extract, Observe) run via WebSocket on live browser sessions.

Which tool is better for real-time web monitoring?

Spider Cloud is better for real-time web monitoring due to its WebSocket-based Browser AI, data connectors (pipe to S3/Supabase), and high-speed Rust engine.

Can Epsilla scrape websites for data?

No, Epsilla is an AI agent builder, not a web scraping tool. It relies on uploaded knowledge bases and does not have built-in crawling or scraping capabilities.

Does Spider Cloud offer an open-source version?

Yes, Spider Cloud has an open-source core available on GitHub, allowing self-hosting as a fallback.

What are the message limits on Epsilla's free tier?

Epsilla's free tier has limited messages, but specific numbers are not publicly listed; it is intended for trial use.

Which tool integrates with LangChain/LlamaIndex?

Spider Cloud integrates with LangChain, LlamaIndex, CrewAI, AutoGen, and more, making it easy to plug into AI workflows.

Which tool is cheaper for high-volume use?

Spider Cloud's pay-as-you-go model ($0.03 per 1,000 pages) is extremely cost-effective for high volume. Epsilla's subscription pricing could be more expensive per message at scale.
