Spider Cloud
Spider Cloud is a web scraping and crawling API that turns live pages into markdown or JSON for agents and RAG pipelines.
Spider Cloud is the pick when rendering throughput matters more than a friendly UI. Three things to price before you commit: residential/ISP pools, AI extraction, and the 2.5x zero-data-retention multiplier all bill on top of the $1/GB headline. The metered model is honest — failed requests cost $0 — and a 429 on Unlimited is explicitly yours to retry, since Spider queues nothing server-side.

Skip Spider Cloud if you need geo-targeting on a flat-rate Unlimited plan, want a visual point-and-click selector builder, or cannot write 429 backoff handling into your scraper client.
AI extraction and Browser AI commands are gated behind an AI Studio subscription starting at $6/mo, on top of whatever you spend on scraping credits.
Pay as you go starts at $5 with volume bonuses kicking in at $500 (+5%) and $2K (+12%), and failed requests cost $0 — cheap for spiky or exploratory workloads. AI Studio Alpha starts at $6/mo on top. Unlimited starts at $40/mo for 2 concurrent requests and reaches 1,538 concurrent at $19,994/mo, with the per-concurrent price falling from $20 to $13. That flat model beats per-request metering only at steady high volume; below that, the metered plan or a cheaper reader like Jina Reader wins on

What's new in Spider Cloud
Checked 7 days agoAcross the latest 5 updates: 4 feature updates and 1 launch.
New Provider router
A router object in a scrape or crawl body asks for an outside provider on your own keys, or mode off keeps a URL on Spider's own stack. Rolling out; email support@spider.cloud to check access.
New Browser AI commands
Act, Extract and Observe commands can be sent directly through Spider's Browser API WebSocket. Requires an AI Studio subscription.
New Scraper catalog
1,000+ ready-made scraper examples across 32 categories, each with working code and a report button if a scraper breaks.
New Data connectors
Set data_connectors on any crawl request to pipe results straight into S3, GCS, Google Sheets, Azure Blob or Supabase as pages are found. Works alongside webhooks.
Smarter AI extraction fallback
AI extraction now runs in two phases: a fast model handles most pages and a more capable model kicks in automatically for complex layouts.

About Spider Cloud
Spider Cloud is a scraping, crawling, and search API for teams that need live web content inside an agent or a retrieval pipeline. One POST /crawl returns a rendered page, streams an entire site back as ordered markdown, or runs a web search that hands back SERP results plus the pages behind them. Most websites ship no API, so Spider renders the page and extracts something a pipeline can actually ingest. The rendering layer carries this product. A request with browser:"browser" runs scripts, waits on lazy images, and follows infinite scroll to the end; return_format:"markdown" drops nav, ads, and footers. Protected pages route through browser.spider.cloud, a real browser engine, and the same pool of 215M+ residential and ISP exits in 199 countries powers both the crawler and the browser, rotated per request. Crawls stream one JSONL line per page the moment it finishes instead of buffering until the last URL. Recent releases push it toward agent workloads: a provider router that hands a URL to an outside provider on your own keys, data connectors that pipe crawl output into S3, GCS, Google Sheets, Azure Blob, or Supabase as pages are found, and an MCP server at mcp.spider.cloud for Claude Code, Codex, Cursor, and Claude Desktop. AI extraction now runs in two phases — a fast model for most pages, a stronger one for complex layouts — and there's a catalog of 1,000+ ready-made scrapers across 32 categories. Billing is deliberately API-first: no dashboard to learn, no visual selector builder. Where Firecrawl and Crawl4AI ask you to route around their limits, Spider sells raw rendering throughput and concurrency you buy outright. Pick it if your bottleneck is pages per second, not clicks.
Behind the Verdict
We'd reach for Spider Cloud the moment a pipeline needs pages at volume and nobody wants to babysit a headless Chrome fleet. Whole-site crawls stream back as JSONL in order, protected pages still return a 200, and the same API key covers scraping, browser sessions, and proxies. That combination is why it keeps showing up in RAG stacks next to LangChain and LlamaIndex. The cost model deserves a hard look before you commit. Pay as you go bills two line items — $1/GB of pre-transformation bandwidth plus $0.0001 per CPU minute — and residential/ISP exits and AI extraction carry their own prices on top. Zero data retention doubles nothing subtle; it bills requests at 2.5x credits. Run a real crawl through the calculator first. A demo crawl is not a production bill. Unlimited is the better deal for steady, high-volume work: buy concurrency from 2 requests in flight ($40/mo) up to 1,538 ($19,994/mo), price per concurrent request sliding from $20 to $13, and run unlimited requests through it. Two limits bite. Geo-targeting isn't available on Unlimited yet, so geo-fenced crawls stay on pay as you go. And when your concurrency is saturated, requests get an immediate 429 with a Retry-After header — nothing queues server-side. If your app can't handle backoff, Unlimited will hurt. Against Firecrawl, Spider trades polish for throughput and control: Firecrawl is easier to start with, Spider is more configurable and cheaper at scale. Against Crawl4AI, you're buying managed rendering and a proxy pool instead of running your own. Against Bright Data or Oxylabs, the pitch is developer ergonomics and one API rather than a raw network. Pass if you need point-and-click scraping with a visual selector builder, or if you want the crawler to ignore robots.txt by default — Spider follows

Real-world workflow fit
Concrete scenarios for the personas Spider Cloud actually fits — and what changes day-one when you adopt it.
POST /crawl for doc.rust-lang.org/book with a limit of 30 and markdown return format; each page arrives as its own JSONL line with a per-page status code.
Outcome: 30 pages of markdown, 319 KB total, all status 200, ready to chunk into a vector store the same afternoon.
Point the coding agent at mcp.spider.cloud and let it read SKILL.md plus the spider-agent CLI, which picks HTTP or a full browser per page, then drive search and scrape calls from inside the editor.
Outcome: The agent can pull live pages into its own context without you writing a scraping client by hand.
Send a prompt with a scrape request so the named fields come back as JSON, add data_connectors to push each crawled page into Google Sheets or S3 as it lands, and let the relevance gate drop off-topic pages before billing.
Outcome: A running price table that updates without a separate ETL step and without paying for pages that don't matter.

Models Under the Hood
as of 2026-10-08
Limitations
- AI extraction and Browser AI commands require an AI Studio subscription (AI Studio Alpha endpoints from $6/mo).
- Pay-as-you-go bills two line items per request — bandwidth ($1/GB of pre-transformation content) and compute ($0.0001 per minute of CPU) — so JS-heavy targets cost more than static ones; failed requests cost $0.
- Unlimited concurrency is picked from 2 up to a self-serve maximum (above that requires sales), requests beyond purchased concurrency get an immediate 429 with a Retry-After header and nothing is queued server-side, and geo-targeting is not yet available on Unlimited.
- The provider router (outside providers on your own keys) is still rolling out and requires contacting support@spider.cloud to check access.

Plans compared
For each published Spider Cloud tier: who it actually fits, and what it adds vs. the previous tier. Cross-reference the cost calculator above for projected annual outlay.
Pay as you go
$1/GB + $0.0001/CPU-min
Ideal for
Developers and small teams with spiky or exploratory scraping volume who don't want a monthly subscription.
What this tier adds
Starting tier: top up from $5, billed at $1/GB of pre-transformation content plus $0.0001 per CPU minute, with failed requests at $0 and a balance that never expires.
AI Studio Alpha
From $6/mo
Ideal for
Teams that already scrape with Spider and want prompt-in / named-fields-out extraction without writing their own parser.
What this tier adds
Adds natural-language endpoints on your existing Spider key: send a prompt, get the named fields back as JSON.
Unlimited
From $40/mo
Ideal for
Steady high-volume crawls where metered per-request billing costs more than a flat concurrency fee.
What this tier adds
Switches from per-request metering to a flat monthly rate priced by concurrency, starting at $40/mo for 2 requests in flight, with the per-concurrent price falling from $20 to $13.
Enterprise
Custom
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.
Pay as you go starts at $5 with volume bonuses kicking in at $500 (+5%) and $2K (+12%), and failed requests cost $0 — cheap for spiky or exploratory workloads. AI Studio Alpha starts at $6/mo on top. Unlimited starts at $40/mo for 2 concurrent requests and reaches 1,538 concurrent at $19,994/mo, with the per-concurrent price falling from $20 to $13. That flat model beats per-request metering only at steady high volume; below that, the metered plan or a cheaper reader like Jina Reader wins on
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 a developer with an API key, first scrape is minutes: copy the setup prompt or the curl example, POST, and read markdown back. Wiring the MCP server into Claude Code or Cursor is a config-file change, so under 15 minutes. A production crawl with retry handling, a relevance prompt and data connectors is a half-day of work. Non-technical users will not get anywhere — there is no visual builder.
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: keep your crawl URLs and swap the endpoint for POST /crawl; outputs come back as streamed JSONL rather than a single payload, so adjust your parser.
- →From Crawl4AI: move from a self-hosted Playwright stack to api.spider.cloud and let the Unblocker and rotating proxy network handle bot walls you were solving yourself.
- →From Jina Reader: replace single-page reads with the same host that also does crawl, search and browser sessions, and add proxy rotation that comes with every request.
- →From Apify: export your actor logic into a Spider scraper from the 1,000+ example catalog and call it directly instead of through a marketplace actor.
- →From a DIY Playwright setup: point browser.spider.cloud at the pages and let stealth and CAPTCHA solving run by default instead of maintaining your own anti-detection patches.
- ↗To Crawl4AI: if licensing and self-hosting matter more than managed proxies, export your target list and run the open-source crawler on your own infrastructure.
- ↗To Firecrawl: if you want a single-payload crawl response and a heavier dashboard, map /crawl to Firecrawl's crawl endpoint and re-test your extraction prompts.
- ↗To Jina Reader: for plain single-page reads at minimal cost, swap the scrape call for a Reader URL prefix.
- ↗To Apify: if you want marketplace actors with a visual interface rather than an API-first tool, rebuild your scrapers as actors.

Featured Head-to-Head Comparisons
Vercel vs Spider Cloud
These aren't competitors, so there's no either/or decision here — most teams building agent products end up using both. If your problem is shipping and operating a web app or agent backend, Vercel is the platform: Git-based CI/CD, preview URLs, a global CDN, serverless functions on Fluid Compute, and the agent stack around AI Gateway, Sandbox, and Workflow SDK. If your problem is getting live web data into an agent or RAG pipeline, Spider Cloud is the data layer: rendered pages, whole-site crawls, search, browser sessions, and proxies behind one key, with an MCP server for Claude Code, Codex, and Cursor. The honest framing is 'budget for both if you need both,' not 'pick one.'
Power Bi vs Spider Cloud
These are not competitors. Power BI is a governed BI layer for Microsoft-centric organizations; Spider Cloud is HTTP plumbing that returns rendered web pages to agents and retrieval pipelines. If you are a data team that already lives in Microsoft 365 or Azure and needs dashboards, semantic models, and Copilot Q&A, Power BI is the pick. If you are building an agent or RAG pipeline and need markdown/JSON page content, whole-site crawls, web search, and proxy handling behind one API key, Spider Cloud is the pick. No realistic buyer shortlists both for the same budget line.
Amplitude vs Spider Cloud
These are not competitors — don't frame this as a pick-one decision. Spider Cloud is infrastructure you buy to get live web pages into an agent or retrieval pipeline; Amplitude is the analytics layer you buy to see what users do inside your product and test changes. The only real overlap is that both now speak MCP, so an engineering team could wire both into the same Claude or Cursor workflow: Spider Cloud as the inbound web-data pipe, Amplitude as the outbound reporting surface. If you're choosing between them on budget, you're solving the wrong problem.
Lm Studio vs Spider Cloud
These are not competitors — they are two halves of a stack, and nobody should be choosing one over the other. Pick LM Studio if your problem is where inference runs: you want open models and the Bionic agent executing on your own Mac, Windows, or Linux machine with nothing leaving your device. Pick Spider Cloud if your problem is where web data comes from: you need rendered pages, whole-site crawls, and SERP results as markdown or JSON inside your agent or RAG pipeline. A team building a private agent often ends up wanting both — Spider Cloud via its MCP server to fetch, LM Studio to reason locally — which is the clearest proof they aren't substitutes.
Tableau vs Spider Cloud
These aren't competitors — pick based on the problem, not the price. If you need dashboards, governed self-service exploration, and agentic analytics on top of data you already store, Tableau is the buy (and its 2026 news — Service Insights from Tableau Next — extends that agentic layer into service teams). If you need the web itself as raw material — rendered pages, site crawls, SERP results — flowing into an agent, MCP client, or RAG pipeline, Spider Cloud is the buy, with the new provider router letting you route requests to outside providers on your own keys. Buying one does not substitute for the other; most data-heavy teams would end up using both.
Looker vs Spider Cloud
These tools are not competitors — they solve different problems for different buyers. Spider Cloud is a developer API for pulling live web data into agents and RAG pipelines, with a freemium entry point and flat-rate Unlimited crawling. Looker is an enterprise BI platform that governs metrics through LookML and layers Gemini conversational analytics on top, sold via sales quote. If you need web scraping, pick Spider Cloud. If you need governed business intelligence on Google Cloud, pick Looker. No one is choosing between them.
Datadog vs Spider Cloud
These are not competitors, so don't treat this as a head-to-head. Choose Datadog if your problem is seeing inside your own production systems — infra, APM, logs, Cloud SIEM/CSPM/CIEM, plus its newer Bits AI incident-response agents, GA GPU monitoring for NVIDIA workloads, and beta Agent Observability. Choose Spider Cloud if your problem is getting data out of websites to feed an agent or RAG pipeline: rendering, crawling, SERP search, unblocking, proxy rotation, and MCP wiring into Claude Code or Cursor. If you're an AI team whose agents need live web data, pick Spider Cloud; if you're an SRE team, pick Datadog. They can coexist in one stack but never substitute for each other.
Jira vs Spider Cloud
These are not competing products and you should not choose between them. Spider Cloud solves the problem of getting live rendered web pages into an AI agent or retrieval pipeline; Jira solves the problem of planning, tracking, and releasing software work. A developer building a RAG pipeline buys Spider Cloud for its rendering layer and 215M+ proxy network. A project manager at a mid-to-large software org buys Jira for Scrum boards, JQL, and issue hierarchy. The only overlap is that both now speak MCP and connect to coding agents — but they sit on opposite sides of that integration.
Postman vs Spider Cloud
These are not substitutes and you should not be choosing between them. Spider Cloud buys live web content — rendered pages, crawls, search results, browser sessions, and proxies — for pipelines and agents that need data the web doesn't expose via API. Postman buys the ability to design, test, mock, monitor, and govern the APIs you build and consume. If your problem is 'the site has no API,' Spider Cloud is the answer; if your problem is 'we have 400 endpoints and no spec, test coverage, or catalog,' Postman is the answer. Plenty of teams happily run both: Postman for the APIs they own, Spider Cloud for the ones that don't exist.
Firebase vs Spider Cloud
These aren't competitors, so don't treat this as a head-to-head pick — if you have to choose one, you're solving the wrong problem. Pick Spider Cloud if your bottleneck is getting live web pages rendered and structured for an agent or RAG pipeline (one POST per page, whole-site crawls, its own proxy network and MCP server). Pick Firebase if your bottleneck is the app around the AI — auth, realtime data, hosting, serverless functions, and Gemini/Genkit features. Teams that actually need both run them side by side: Firebase for the app, Spider Cloud for the web data feeding it.
Neon vs Spider Cloud
These are not competitors — picking one does not preclude the other, and most buyers evaluating them have different problems. If you are building a serverless app, multi-tenant SaaS, or an agent backend and need autoscaling Postgres with branching, auth, object storage, and functions in one deploy (the neon.ts + neon deploy flow), Neon is the shortlist pick. If you need live web pages rendered and returned as markdown or structured JSON for a RAG pipeline or crawling agent, Spider Cloud is the shortlist pick. A team building agents could legitimately use both: Neon as the data/backend layer, Spider Cloud as the web-access layer. Choose by the problem, not against each other.
Fly Io vs Spider Cloud
These are not competitors — pick by the problem, not against each other. If your bottleneck is getting live, rendered web pages into an agent or RAG pipeline (CAPTCHAs, bot walls, infinite scroll, whole-site crawls), Spider Cloud is the obvious buy. If your bottleneck is giving an agent a persistent, hardware-isolated computer with checkpointing and near-zero idle cost, Fly.io is the obvious buy. Many teams will end up paying for both: Fly.io runs the agent, Spider Cloud feeds it the web.
