Spider Cloud and Glen solve completely different problems. Choose Spider Cloud if you need a fast, cost-effective web scraping API for feeding live data into AI agents or RAG pipelines. Choose Glen if your team runs multiple MCP-compatible coding agents (Claude Code, Cursor) and needs a shared memory layer to keep them consistent. They are complementary, not competitive.

    Pick: Spider Cloud

    Spider Cloud provides fast scraping at low cost ($0.03/1k pages) and integrates with LangChain/LlamaIndex for RAG.

  • Engineering team running multiple Claude Code agents that need consistent context (e.g., coding conventions)
    Pick: Glen

    Glen automatically captures agent decisions and makes them available to all agents via MCP, ensuring consistency.

  • Developer needing to extract product data from hundreds of sites into Google Sheets
    Pick: Spider Cloud

    Spider Cloud supports data connectors to Google Sheets and has ready-made scraper examples for common sites.

  • Support team with multiple AI agents answering customer queries; wants consistent policy answers

    Glen stores policy decisions and makes all agents answer consistently, with provenance and RBAC for compliance.

  • AI startup that needs both web data and shared memory for its agents
    Pick: Spider Cloud

    Use both: Spider Cloud for scraping, Glen for memory. They are complementary and can be integrated via API/plugins.

Frequently Asked Questions

Glen vs Spider Cloud: which should you choose?

Spider Cloud and Glen solve completely different problems. Choose Spider Cloud if you need a fast, cost-effective web scraping API for feeding live data into AI agents or RAG pipelines. Choose Glen if your team runs multiple MCP-compatible coding agents (Claude Code, Cursor) and needs a shared memory layer to keep them consistent. They are complementary, not competitive.

Can Spider Cloud handle JavaScript-heavy sites?

Yes, the Browser Cloud with stealth anti-detection renders JavaScript, and Browser AI commands (Act, Extract, Observe) provide AI-driven interaction.

Does Glen require my agents to be MCP-compatible?

Yes, Glen integrates via the MCP protocol, so it works with clients like Claude Code, Cursor, and Codex. For non-MCP agents, custom integration may be needed.

Is Spider Cloud suitable for large-scale scraping (millions of pages)?

Yes, it uses a Rust engine for performance and offers rotating proxies. Failed requests are free, and cost is $0.03/1k pages, making it cost-effective at scale.

Can I self-host Spider Cloud?

Yes, there is an open-source core available on GitHub for self-hosting, in addition to the cloud service.

What kind of knowledge does Glen capture automatically?

It captures observations from agent interactions: decisions, processes, preferences, and facts. This happens automatically without manual input.

Does Spider Cloud support image extraction?

Yes, it supports screenshot capture and can extract data from pages, though primarily focused on text content.

Does Glen offer audit trails for compliance?

Yes, the Scale+ plan includes audit logs and access reviews, along with SAML SSO for enterprise compliance.

Can I try both products for free?

Both offer freemium tiers. Spider Cloud has a free tier with limited usage; Glen's free tier is available but may require joining a waitlist.
