Can E2B be used for web scraping?

E2B is not designed for web scraping; it's for code execution. Spider Cloud is the appropriate choice for scraping.

Does Spider Cloud execute code?

Spider Cloud does not execute arbitrary code; it crawls and scrapes web pages. Use E2B for code execution.

Which tool is cheaper for high-volume tasks?

Spider Cloud's per-page pricing is more predictable for large-scale scraping. E2B's per-second billing can become expensive for long sessions.

Do both tools have a free tier?

Yes, both offer free tiers. E2B's free tier includes limited sandbox time; Spider Cloud's free tier includes a limited number of pages.

Which integrates with LangChain?

Both integrate with LangChain. E2B provides a sandbox tool; Spider Cloud provides a web loader and retrieval tools.

Is there Browser AI commands in E2B?

No, E2B does not offer Browser AI commands. Spider Cloud recently launched Act, Extract, and Observe via WebSocket.
