Who should pick which
- AI agent developer building autonomous web navigatorsPick: Steel Browser
Steel provides full browser control via WebSocket, persistent profiles, CAPTCHA solving, and stealth anti-detection, essential for agents that need to log in, fill forms, and maintain state.
- RAG pipeline builder needing up-to-date web dataPick: Spider Cloud
Spider Cloud's low cost per page, structured outputs, and integrations with LangChain/LlamaIndex make it ideal for feeding fresh data into LLM applications and knowledge bases.
- Solo founder with a limited budget for web scrapingPick: Spider Cloud
With a generous free tier and very low per-page cost (fraction of a cent), Spider Cloud is budget-friendly for small-scale scraping while still offering powerful AI extraction.
- QA engineer testing multi-session web appsPick: Steel Browser
Steel's ability to spin up sandboxed browser sessions with unique profiles and dedicated IPs is perfect for testing authentication flows, multi-step workflows, and regression tests.
- Developer needing a one-off scrape of a complex sitePick: Spider Cloud
Spider Cloud's scraper catalog and AI Studio allow natural language description of scrape tasks, lowering the learning curve for ad-hoc extraction without writing code.
Frequently Asked Questions
Steel Browser vs Spider Cloud: which should you choose?
For AI agent developers needing granular browser control, session persistence, and CAPTCHA handling, Steel Browser is the clear choice with its open-source cloud browser API and native SDKs. For high-volume, low-cost structured data extraction and RAG pipelines, Spider Cloud offers superior pricing (pennies per thousand pages) and a rich ecosystem of integrations with AI frameworks. Choose Steel if you need to automate complex browser interactions; choose Spider Cloud if you need fast, affordable crawling and structured outputs.
Which tool is better for CAPTCHA handling?
Steel Browser has built-in auto-upsolve for CAPTCHAs during browser sessions. Spider Cloud has a Silk AI model that handles captchas as part of extraction, but it's an add-on feature. Steel is more focused on CAPTCHA solving as a core feature.
Can I use Steel Browser for static HTML scraping?
Yes, Steel offers a one-shot scraping endpoint that returns HTML, Markdown, or screenshots. But its strength is full browser automation; for static scraping, Spider Cloud is more cost-effective.
Does Spider Cloud support persistent browser sessions?
Spider Cloud's Browser AI commands (Act, Extract, Observe) allow interaction via WebSocket, but it does not emphasize persistent profiles like cookies or extensions. Steel is the go-to for session persistence.
Which tool has better integration with AI agents?
Both: Steel integrates with OpenAI Agents SDK, Claude Computer Use, Stagehand, and Browser Use. Spider Cloud integrates with LangChain, LlamaIndex, CrewAI, AutoGen, and Dify. Choice depends on your stack.
What is the cost difference for 100,000 pages?
At Spider Cloud's average $0.03 per 1k pages, 100k pages would cost roughly $3. Steel Browser charges per session hour, not per page; assuming 1 page per session and 100k sessions, at 1 session per page, cost would be high ($0.40/hr * hours). For static scraping, Spider Cloud is far cheaper.
Can I use Steel Browser locally?
Steel is designed as a cloud browser API. While it's open-source, running it locally requires self-hosting. Spider Cloud also offers an open-source core for self-hosting, but both are primarily cloud services.
Which tool is better for bypassing anti-bot measures?
Steel uses a stealth browser fork and dedicated IPs. Spider Cloud uses rotating proxies and an AI unblocker endpoint. Both have anti-detection, but Steel's dedicated IPs provide more stability for sessions requiring consistent origin.
Do both tools have free tiers?
Yes. Steel offers limited free sessions. Spider Cloud offers 100 free pages per month. Both allow you to test without upfront payment.
