For AI agents that need live web data for RAG, Spider Cloud is the unmatched choice with its low cost, high success rate, and extensive integrations. CubeSandbox solves a different problem—secure code execution—and is ideal for multi-agent systems needing isolated sands but lacks recent updates. Pick based on whether you need to ingest the web or run untrusted code.

Who should pick which

  • Solo AI developer building a RAG app
    Pick: Spider Cloud

    Low cost ($0.03/1k pages), easy integration with LangChain/LlamaIndex, and AI Studio for natural language crawling.

  • Team building multi-agent system with untrusted code
    Pick: CubeSandbox

    Hardware-isolated MicroVMs, snapshot cloning, and eBPF security are essential for safe concurrent execution.

  • Data scientist needing structured web data for LLM training
    Pick: Spider Cloud

    99.9% success rate, multiple output formats (JSON, CSV), data connectors to S3/GCS streamline ingestion.

  • DevOps migrating from E2B Cloud to self-hosted sandboxes
    Pick: CubeSandbox

    E2B SDK compatibility for drop-in replacement and high-density deployment reduce cloud costs.

  • Prompt engineer needing browser automation (click, type, observe)
    Pick: Spider Cloud

    New Browser AI commands via WebSocket enable direct interaction with web pages from AI agents.

Frequently Asked Questions

CubeSandbox vs Spider Cloud: which should you choose?

For AI agents that need live web data for RAG, Spider Cloud is the unmatched choice with its low cost, high success rate, and extensive integrations. CubeSandbox solves a different problem—secure code execution—and is ideal for multi-agent systems needing isolated sands but lacks recent updates. Pick based on whether you need to ingest the web or run untrusted code.

Can Spider Cloud extract data from JavaScript-heavy sites?

Yes, it uses a Browser Cloud with stealth anti-detection and can execute JavaScript; new Browser AI commands (Act, Extract, Observe) handle complex interactions.

Does CubeSandbox support persistent storage?

Yes, it offers state snapshots, rollback, and clone capabilities, allowing you to save and restore sandbox state.

Which tool integrates better with LangChain?

Spider Cloud has direct integrations with LangChain, LlamaIndex, CrewAI, and more, making it ideal for RAG pipelines.

Is CubeSandbox free to self-host?

Yes, it is open-source and freemium; you can self-host without licensing fees, though infrastructure costs apply.

How does Spider Cloud handle failed requests?

Failed requests are not billed, and it provides automatic retries with rotating proxies via the unblocker endpoint.

Can CubeSandbox run GUI applications?
