About Spider Cloud
Spider Cloud is a developer-focused web scraping API that turns any website into clean markdown, JSON, or raw HTML, feeding live web data into AI agents and RAG pipelines. It's built for teams that need fast, large-scale crawling without managing headless browsers or rotating proxies themselves. At a default 10,000 core API requests per minute and a Rust-based engine, it can stream whole sites as markdown or structured JSON at over 100K pages per second. That raw speed pairs with a stealth browser layer and a proxy pool of 215M+ residential and ISP IPs across 199+ countries, so you can parse anti-bot sites without building your own evasion infrastructure. What sets Spider apart is how deeply it's wired for AI workflows. The Silk model, exclusive to Spider, converts raw HTML into structured data and solves captchas on dedicated GPUs—no external AI calls needed. For non-developers, the AI Studio add-on (from $6/mo) brings natural-language crawling, scraping, and search, while the Web Search API bundles SERP, scraping, and extraction into one request. The /ai/search endpoint searches the web, scrapes results, and applies AI extraction to each page, with a relevance gate that skips pages irrelevant to your prompt—a real cost-saver on broad crawls. You can also pass an extraction_schema to enforce exact JSON structure from the AI, and Browser Cloud exposes full browser sessions over CDP with AI commands like Act, Extract, and Observe. Data delivery is flexible: Spider returns HTML, raw, plain text, and multiple markdown formats, with API responses in JSON, JSONL, CSV, and XML. Data connectors pipe results directly to S3, GCS, Google Sheets, Azure Blob, or Supabase, eliminating pipeline glue code. Native integrations for LangChain, LlamaIndex, CrewAI, FlowiseAI, AutoGen, and Agno mean agents can plug Spider in with minimal boilerplate. Where Spider competes hardest is price-performance for high-volume extraction: at $1/GB plus $0.001/min compute, or a flat-rate
Behind the Verdict
Spider Cloud earns its place in any serious AI data stack, but it's not for everyone. We'd reach for it when you're building agents or RAG pipelines that need live web data at scale. The flat-rate Unlimited plan is the standout: at $40/mo for 2 concurrent requests, it beats Firecrawl's per-credit pricing hands-down for sustained crawls. Even the pay-as-you-go option is fair—$1/GB of pre-transformation content plus $0.001 per minute of compute, with failed requests billed at $0. That's a rare honesty. Where it bites: the Unlimited plan doesn't yet support geo-targeting, and residential/ISP proxies are priced separately from the base plan. If you need to scrape from specific countries or rotate residential IPs heavily, your costs climb. For casual, low-volume scraping, a free tier might suffice—Spider has no persistent free tier, just a $5 top-up to start. Compared to Firecrawl, Spider wins on raw throughput and AI features like the Silk model and /ai/search with relevance gate. Firecrawl still holds an edge in some developer ergonomics, but Spider's open-source core (GitHub 2.7k stars) and active changelog show steady momentum. Real-world caveats: You'll need to respect rate limits—429s are returned immediately when Unlimited concurrency is exhausted, so build retry logic. Also, AI extraction power varies by page complexity; the two-phase fallback helps, but complex layouts may need the more capable model. For teams already using LangChain or LlamaIndex, the native integrations make setup painless. Otherwise, the API is straight REST—easy to adopt with any HTTP client.

Real-world workflow fit
Concrete scenarios for the personas Spider Cloud actually fits — and what changes day-one when you adopt it.
You need to answer questions from live web data. You set up Spider's /crawl endpoint to fetch a set of URLs, then use the /ai/search endpoint to search and extract relevant paragraphs.
Outcome: Your agent can pull real-time information in markdown or JSON, feeding it into your LLM prompt for grounded answers.
You want to monitor competitor prices daily. You use the scraper catalog's Amazon scrape example and schedule a /crawl request, piping results to Google Sheets via data_connectors.
Outcome: You get a daily automated update of competitor prices without manual scraping, and you can set alerts when prices change.
You need to extract structured data from thousands of news articles. You use the /ai/search endpoint with a relevance gate to only process relevant pages, and extraction_schema to enforce a JSON format.
Outcome: You build a clean, labeled dataset with minimal cost, skipping irrelevant pages and getting consistent structured output.
Use Cases
- Feed real-time web data into an LLM-powered research agent that answers questions from live websites.

What this tier adds
Starting entry point; pay per GB of bandwidth and compute, with no expiry on balance, unlike the monthly Unlimited plan.
Unlimited
$40/mo (2 concurrency)
Ideal for
High-volume teams with sustained crawling workloads who want predictable monthly costs and unlimited requests at a fixed concurrency level.
What this tier adds
Flat monthly rate instead of per-GB billing; per-unit cost drops from $20 to $13 as concurrency increases, and includes JS rendering and standard proxy rotation.
AI Studio Alpha
$6/mo
Ideal for
Non-developers or teams that want to use natural-language crawling and searching, or need Browser AI commands (Act, Extract, Observe) without writing complex code.
What this tier adds
Adds natural-language endpoints and enables Browser AI commands via WebSocket; requires existing API key and is an add-on to Pay-as-You-Go or Unlimited.
Where the pricing makes sense
The company stage and team size where Spider Cloud's pricing actually pencils out — and where peers do it cheaper.
Spider's pay-as-you-go at $1/GB is competitive for low-volume use, but the flat-rate Unlimited plan (from $40/mo) is a standout for high-volume crawlers. Compared to Firecrawl, which charges per credit, Spider's Unlimited offers predictable monthly costs. For $350/mo you get 25 concurrent requests, allowing unlimited scraping. If you need residential proxies or geo-targeting, competitors like ScraperAPI or Zyte may be better, but at higher cost. For AI-focused scraping, Spider's AI Studio adds
Setup time & first value
How long it actually takes to get something useful out of Spider Cloud — broken out by persona, not the marketing-page minute.
For developers, you can be up in minutes: sign up, get an API key, and run your first /scrape request within 5-10 minutes. Integrating with LangChain or LlamaIndex takes another 15-30 minutes using the official packages. For non-developers using AI Studio, you can start with natural-language queries without writing code, with a steep learning curve of about an hour to explore the playground.
Switching to or from Spider Cloud
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Firecrawl: If you're using Firecrawl, you can replace calls with Spider's /scrape or /crawl endpoints, using markdown or JSON output. Update your API key and possibly adjust rate limits; the design is similar,
- ↗To Firecrawl: If you outgrow Spider or need features like JavaScript rendering with their specific pricing, you can switch by updating endpoints and handling API key replacement. Both offer similar output formats, so
