Side-by-side comparison of features, pricing, and ratings
At a glance
| Dimension | Stash | Spider Cloud |
|---|---|---|
| Primary Use Case | Persistent memory & state for AI agents | Web data extraction for AI agents & RAG |
| Pricing | Free (open source, you host) | Freemium (200 free credits/mo, then ~$0.03/1k pages) |
| Deployment | Self-hosted only (single binary, requires PostgreSQL) | Cloud API + optional self-hosted open source core |
| Storage Backend | PostgreSQL (SQL queryable memory) | Connectors: S3, GCS, Sheets, Azure Blob, Supabase |
| AI Integration | MCP server, episodes/facts/context for agents | LangChain, LlamaIndex, CrewAI, AutoGen, Dify, etc. |
| Latest News Impact | No recent news; assume classic feature set | Browser AI commands, scraper catalog with 1k+ examples |
Choose Spider Cloud if you need to feed web data into AI agents—its Rust engine, 99.9% success, and new Browser AI commands make it cost-effective for RAG pipelines. Choose Stash if you need a self-hosted memory layer for agents that persist conversations, facts, and state in Postgres—best for privacy-first or offline autonomous systems. They solve different problems: one fetches data, the other remembers it.
AI web scraping API: crawl, scrape, search any site into markdown or JSON at 10k req/min.

Frequently Asked Questions
Stash vs Spider Cloud: which should you choose?
Choose Spider Cloud if you need to feed web data into AI agents—its Rust engine, 99.9% success, and new Browser AI commands make it cost-effective for RAG pipelines. Choose Stash if you need a self-hosted memory layer for agents that persist conversations, facts, and state in Postgres—best for privacy-first or offline autonomous systems. They solve different problems: one fetches data, the other remembers it.
Can Spider Cloud extract data from JavaScript-heavy pages?
Yes—Spider Cloud's Browser Cloud uses stealth anti-detection and its Rust engine handles dynamic content. The new Browser AI commands (Act, Extract, Observe) via WebSocket allow interaction with SPAs.
Does Stash work without an internet connection?
Yes. Stash is self-hosted, offline capable, and requires only PostgreSQL. No cloud dependency means it can run on air-gapped networks.
How does Spider Cloud price compare to other scraping APIs?
At $0.03 per 1k pages (only successful requests billed), Spider Cloud is among the cheapest. The 200 free monthly credits allow low-volume testing.
Can I query Stash's memory with SQL?
Yes—Stash stores episodes, facts, and context directly in PostgreSQL, so you can use standard SQL to analyze or filter agent memories.
Which tool integrates with LangChain?
Spider Cloud directly integrates with LangChain, LlamaIndex, CrewAI, AutoGen, FlowiseAI, Agno, Dify, and more. Stash does not list specific integrations but provides an MCP server.
Do either tools support real-time streaming?
Spider Cloud offers WebSocket-based Browser AI commands for real-time interaction (Act, Extract, Observe). Stash is not real-time; it stores state for later retrieval.
Is open source available for both?
Spider Cloud has an open-source core on GitHub but recommends the cloud API for reliability. Stash is fully open source (license not specified but free to self-host).
Can I use both tools together?
Absolutely—Spider Cloud can scrape web data and feed it into an AI agent, while Stash provides persistent memory so the agent remembers past interactions and facts.
