02 Why Crawlbase exists
Web data breaks. We absorb the break.
Websites change constantly. Layouts shift, anti-bot systems update, IP ranges get blocked. Teams that depend on web data end up maintaining scrapers instead of using the data.
Crawlbase runs that layer for you. When a site changes, it is our problem to solve, not yours.
01A site updates its anti-bot defenseswe adapt the path
Every request takes the same six-stage path: receive, route, render, extract, store, deliver. Everything between is operated and monitored by us.
01
Receive URL
One endpoint accepts the target page and your options.
02
Route
Picks the proxy and region that reach the site cleanly.
03
Render
Runs a real browser when the page needs JavaScript.
04
Extract
Parses the page into clean, typed fields with scrapers.
05
Store
Keeps results available without your own storage layer.
06
Deliver
Returns JSON in the response or through a callback.
A request travels the pipeline continuously.
04 Products
Five building blocks for web data.
Crawling API
One endpoint for any page.
Send a URL and receive clean HTML or structured data, with browser rendering and anti-bot handling built in. Add a scraper parameter to get typed fields instead of markup.
Push millions of URLs and receive results through callbacks, without managing queues or workers yourself. Built for steady, high-volume pipelines that run unattended.
Residential and datacenter IPs across 30 geographies, rotated automatically and routed through the path most likely to succeed. One proxy endpoint instead of a pool to manage.
Connect a model to current pages through the Model Context Protocol and let it read the web directly. The agent asks for a page, Crawlbase fetches and returns it.
One token, every product. Drop Crawlbase into your code with an official SDK, or wire it into the automation and AI tools you already use. It all runs on the same API.
SDKs
Official client libraries.
Plain HTTP underneath, with maintained SDKs for Node, Python, Ruby, PHP, Java, .NET and Go, so you integrate in a few lines.
"At Intel we need data at scale. Crawlbase has helped on our data demands, letting us crawl billions of documents in a short period."

"We've used Crawlbase for years to power parts of our aggregation pipeline with information we couldn't otherwise get through traditional means."
Raiph Edwards

"Crawlbase helped us scale our data scraping in a fast, easy and cost-effective way."
Patrick Gouy

"It's critical to gather data regularly. Crawlbase has helped us consistently meet demand for reviews and analytics."
Chris Johnson
CEO · UpscaleMethod
"Crawlbase helps us test sites that would otherwise be very difficult to crawl, and be more confident in the results we pass to our users."
Loftie Ellis
CEO · PageWatch
"Instead of handling proxies, infrastructure and ever-changing CAPTCHA systems ourselves, we delegate to the Crawlbase API and get the problem solved."
Crawlbase is web data infrastructure for developers, enterprises, and LLMs. It lets you crawl and scrape any website and receive clean, structured data through one platform, including a crawling API, a smart AI proxy, an enterprise crawler, managed scrapers, cloud storage, and a Web MCP Server for AI agents.
You send a URL to the API with your token. Crawlbase routes the request through a rotating residential proxy with the correct geolocation, renders the page when JavaScript is required, handles CAPTCHAs and bot checks automatically, and returns clean structured JSON.
No. Proxy rotation, geotargeting, retries, rendering, and anti-bot handling all run inside the platform. You send a URL and receive structured data. There is nothing to wire together and nothing to maintain when a site changes its anti-bot setup.
Yes. The Crawlbase Web MCP Server gives AI agents and LLMs live, structured web data through the Model Context Protocol, so your models and RAG pipelines can request and receive fresh web data directly.
You can start free with 1,000 requests and no credit card. Paid plans scale with usage across the crawling API, smart AI proxy, scrapers, enterprise crawler, storage, and Web MCP Server.
Yes. For very large jobs, the asynchronous Enterprise Crawler uses callbacks to crawl millions of pages without you running any infrastructure.
09 Reference
What is web data infrastructure?
Crawlbase is the layer between the public web and the products developers and enterprises build on top of it. Instead of stitching together proxies, headless browsers, anti-bot handling, and parsers, you call one platform that runs all of it.
DEF / 01Since 2017
The layer 70,000 teams build on
More than 70,000 developers and data teams use Crawlbase to crawl and scrape websites at scale, turning messy HTML into clean structured data without running scraping infrastructure of their own.
DEF / 02API vs API
Web scraping API vs. web crawling API
A web scraping API extracts specific structured fields from a page, such as a product's name, price, and rating. A web crawling API fetches and renders the full page so you can collect everything on it. Crawlbase gives you both, plus the smart AI proxy and enterprise crawler that make either possible at volume.

Built for developers, enterprises & LLMs
Developers ship faster with one API, official SDKs, code examples, and in-depth guides. Enterprises run reliable pipelines at a 99% average success rate. AI teams feed models and agents fresh structured data through the Web MCP Server.
