MemOS vs Spider Cloud
Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | MemOS | Spider Cloud |
|---|---|---|
| Pricing | Freemium: Free cloud tier with limited memory; paid plans undisclosed | Freemium: $0 for 500 pages/mo; plans start at $40/mo (10K pages); AI Studio add-on $6/mo |
| Core Focus | Persistent memory management for LLMs | Web data extraction for AI agents |
| Performance | Millisecond latency; SOTA on memory benchmarks | 99.9% success rate; ~$0.03/1K pages |
| Key Innovation | Hybrid retrieval; layered knowledge graph; predictive scheduling | Rust engine; Browser AI commands (Act/Extract/Observe) |
| Integration Depth | OpenClaw, MindDock, ClawForce, MCP, GitHub | LangChain, LlamaIndex, CrewAI, data connectors (S3, Sheets, etc.) |
| Deployment | Cloud API; MemOS Lite local-first; open-source core | Cloud API; open-source self-host option |
Choose Spider Cloud if your AI agent's priority is fetching fresh, structured web data at scale—its Rust engine and Browser AI commands deliver speed and reliability at low cost. Pick MemOS if the bottleneck is memory persistence across sessions; its hybrid retrieval and knowledge graph excel at maintaining context, but it requires deeper integration. They solve different problems—combining both could create a powerful autonomous agent stack.
AI web scraping API: crawl, scrape, search any site into markdown or JSON at 10k req/min.

Frequently Asked Questions
MemOS vs Spider Cloud: which should you choose?
Choose Spider Cloud if your AI agent's priority is fetching fresh, structured web data at scale—its Rust engine and Browser AI commands deliver speed and reliability at low cost. Pick MemOS if the bottleneck is memory persistence across sessions; its hybrid retrieval and knowledge graph excel at maintaining context, but it requires deeper integration. They solve different problems—combining both could create a powerful autonomous agent stack.
Can Spider Cloud extract data from JavaScript-heavy sites?
Yes, it uses Browser Cloud with stealth anti-detection and now supports Browser AI commands (Act, Extract, Observe) via WebSocket for interactive pages.
Does MemOS require a specific LLM framework?
No, MemOS provides a cloud API that works with any LLM. It also integrates deeply with OpenClaw, but can be used independently.
How does Spider Cloud handle anti-bot measures?
It uses rotating proxies, automatic retries, and an /ai/unblocker endpoint to bypass common anti-bot systems.
Is MemOS free for commercial use?
The free cloud tier has limits; MemOS Lite is open-source. Commercial use may require a paid plan or enterprise license—contact MemOS for details.
Can I use both tools together?
Yes, they are complementary. Spider Cloud fetches data, and MemOS stores context from previous interactions, enabling agents that both gather and remember information.
Does Spider Cloud support scheduled scraping?
Not natively via the API, but you can use external schedulers (e.g., cron jobs) to trigger crawl requests.
What programming languages can use MemOS?
MemOS provides a cloud API with a few lines of code—works with any language that can make HTTP requests. Python client is common.
How accurate is MemOS's memory retrieval?
MemOS achieved SOTA on LoCoMo and LongMemEval benchmarks, using hybrid retrieval and layered knowledge graphs for precise context recall.
