AI-Search vs Spider Cloud

These products differ in kind, not degree. Spider Cloud is a request-level API: POST /scrape or /crawl returns a page or an entire site as markdown, JSON, HTML, raw, or plain text, streaming each page as one JSONL line the moment it finishes rather than buffering the whole crawl. Its rendering layer runs scripts, waits on lazy images and follows infinite scroll; protected pages route through browser.spider.cloud's real browser engine, and Browser Cloud runs full anti-detection sessions with rotating residential/ISP exits. AI extraction is two-phase (fast model, stronger model on complex layouts) with an extraction_schema that forces output to conform to a JSON schema, and a September 2026 provider router can send requests to outside providers on your own keys. Data connectors pipe crawl output into S3, GCS, Sheets, Azure Blob or Supabase as pages land. Integrations are all developer plumbing: LangChain, LlamaIndex, CrewAI, MCP, Claude Code, Cursor, Codex.

AI-Search shares none of that surface. It indexes 797 items across 42 sources — Hacker News (110), GitHub (76), Hugging Face Papers (50), plus OpenAI, Anthropic, TechCrunch, arXiv — and rewrites framing into Chinese, attaching a one-line AI 点评 to each article and a weekly AI 总结 (the latest framed the week around Claude Sonnet 5.5 and GPT-6 Astra). Navigation is time filters (24h/3d/7d/30d), topic hubs (AI Agent, 155 items; Anthropic/Claude, 90), per-source counters that flag stalled sources, category filters, a ⌘K palette, read/unread tracking and saved collections.

The overlap is nominal: one is a scraper, one consumes other people's scrapes as editorial.

Spider Cloud is freemium, and the commercial pitch is in the metering model rather than a sticker price: its Unlimited tier is positioned as flat-rate with Unlimited concurrency, which the vendor contrasts with metered per-request billing — the argument being that high-throughput crawls that process millions of pages outperform per-request pricing. Two caveats carry direct cost implications. Geo-targeted crawls are not available on Unlimited yet, so geo work needs a different arrangement. And Unlimited queues nothing server-side, so your application must handle HTTP 429s itself or you lose throughput to throttling. The AI browser commands (Act, Extract, Observe over the Browser API WebSocket) require an AI Studio subscription, which is a separate line item from base scraping. For a team comparing this against another scraping API, the meaningful comparison is flat-rate concurrency versus metered requests at your actual page volume, plus whether you need the AI Studio tier and whether geo matters.

AI-Search costs nothing and has no login, no seat and no usage tier. That is the entire pricing story — a free browser tool. It makes no revenue claim in the data provided, so there is no upsell, no API quota and no paid tier to weigh. This is why the two do not sit on one budget line: one is a metered infrastructure purchase you size against crawl volume, the other is a free read.
