API Website Crawler

Fetch public pages with fast HTTP crawling (no JavaScript). Best first choice for static or server-rendered HTML; use Rendering or WebUnlocker when JS or anti-bot blocks you.

Choosing the right endpointLink to Choosing the right endpoint

Piloterr exposes three complementary ways to fetch a public web page. Pick the lightest engine that works for your target site.

Endpoint Engine Credits Use when
Website Crawler HTTP request (no JavaScript) 1 The HTML you need is already in the first response: blogs, docs, server-rendered catalog pages, sitemaps.
Website Rendering Headless browser (JavaScript executed) 2 Content appears only after JS runs: React/Vue/Angular SPAs, lazy-loaded listings, pages that need wait_for or POST browser_instructions.
Website WebUnlocker Browser + unlock stack 3 Website Rendering or Website Crawler hit bot walls (Cloudflare, DataDome, Akamai, PerimeterX) and the domain is on Piloterr's approved whitelist.

Decision flow

  1. Try Crawler first if you do not need client-side rendering. It is the fastest and cheapest option.
  2. Switch to Rendering when the DOM is empty, prices load asynchronously, or you must wait for a selector / run browser steps.
  3. Escalate to WebUnlocker only for hardened retail or marketplace domains that block normal browser traffic. Whitelist approval is required before production use.

OverviewLink to Overview

Website Crawler sends a direct HTTP GET to a public URL and returns the page HTML. No headless browser runs: there is no JavaScript execution, no DOM rendering, and no anti-bot unlock layer.

That makes Crawler ideal for volume and speed on sites that already ship meaningful HTML in the first response. When the page is a SPA, loads data after scroll, or sits behind advanced bot detection, move up to Website Rendering or Website WebUnlocker (see table above).
