Overview

Bright Data Web Unlocker is an API for accessing websites that would otherwise block automated requests. It combines proxy rotation, CAPTCHA solving, JavaScript rendering, and anti-bot handling so teams can request a page and receive usable output without managing the underlying unlocking workflow themselves.

The product page presents it as a way to focus on data extraction rather than scraping infrastructure. It is aimed at developers and teams working with protected sites who need clean HTML, JSON, Markdown, or screenshots from a single request.

Features

Single-call web unlocking

Routes requests through Bright Data infrastructure to handle proxy rotation, CAPTCHA solving, and anti-bot measures in one API call.

Multiple response formats

Returns output as clean HTML, JSON, Markdown, or a screenshot, depending on the request format.

Built-in JavaScript rendering

Includes JavaScript rendering for pages that need client-side execution before content can be extracted.

Browser behavior handling

Uses browser fingerprinting, cookies, and session handling to imitate normal browsing behavior on protected sites.

Developer-facing setup materials

Provides code examples and step-by-step documentation for cURL, Node.js, and Python integration.

Extended request options

Supports geolocation targeting and screenshot output according to the documentation referenced on the product page.

Use Cases

Access protected websites
Use Web Unlocker when a target site blocks automated requests, requires CAPTCHA solving, or depends on browser-like behavior before content is visible.
Extract rendered page data
Use the API to capture structured output from pages that need JavaScript rendering, cookies, or session continuity before extraction.
Add unlocking to a scraper workflow
Use the available code examples and simple request flow to embed unlocking into an existing scraping service or internal data pipeline.
Generate alternate page outputs
Use the screenshot and Markdown output options when a downstream process needs a visual record or a text-friendly page representation.
