# Web Unblocker — 即将上线

Web Unblocker 是一款托管式代理，内置 JavaScript 渲染、验证码处理、请求头轮换与重试——你只需把请求指到一个端点并传入目标 URL，即可拿到渲染后的 HTML。

## 预期能力

* 单一端点，任意目标站点
* 内置无头浏览器，自动执行 JS
* 自动处理验证码
* 按请求次数计费
* 与住宅代理端点同形可替换，无需 SDK

## 加入候选名单

发邮件至 **<support@helodata.com>**，主题填 `Web Unblocker waitlist`，简要说明使用场景。

## 过渡方案

* 使用[住宅代理](/helodata-zh/chan-pin/overview.md)搭配无头浏览器（Playwright、Puppeteer）实现同样的形态，只是要写些胶水代码。集成示例：[Playwright](/helodata-zh/ji-cheng-zhi-nan/pa-chong-gong-ju/playwright.md)、[Puppeteer](/helodata-zh/ji-cheng-zhi-nan/pa-chong-gong-ju/puppeteer.md)。
