They solve different problems – one is a development framework, the other a data extraction API.

What does sunpeak do that Spider Cloud cannot?

sunpeak is a framework for building interactive MCP apps that run inside AI hosts (ChatGPT, Claude). It provides a React-based development environment with hot reloading, multi-host inspector, and built-in testing. Spider Cloud is a web scraping and crawling API focused on data extraction for AI agents.

Can Spider Cloud be used to build MCP apps?

No. Spider Cloud provides web data for MCP tools but does not offer a framework for building the UI or logic of MCP apps.

Is sunpeak free forever?

Yes, sunpeak is open-source under MIT license, so it is free to use, modify, and self-host with no paid tiers.

Does Spider Cloud have a free plan?

Spider Cloud offers a freemium model with pay-per-page pricing; there is no free tier, but it offers an open-source core for self-hosting.

Which tool supports ChatGPT and Claude integration?

sunpeak directly supports building apps that run inside ChatGPT and Claude via MCP. Spider Cloud is an external data source for agents.

Can I use Spider Cloud for visual regression testing?

No, Spider Cloud does not offer visual regression testing. That is a feature of sunpeak's Playwright integration.

Which tool is better for RAG pipelines?

Spider Cloud is purpose-built for RAG, offering structured output and integrations with LangChain, LlamaIndex, and vector databases. sunpeak is not designed for data ingestion.

Do both tools support real-time browsing?

Spider Cloud offers Browser AI commands via WebSocket (Act, Extract, Observe) for live interactions. sunpeak does not provide real-time browsing – it runs inside AI hosts with simulated or live host testing.
