hongnoul 推出 hwatu：为 AI agent 优化的高性能验证浏览器

开发者 hongnoul 推出了 hwatu，一款专为 AI agent 设计的开源验证浏览器工具 1。该项目采用 WebKitGTK-6.0 实现，以极低的延迟和高效的单次调用检查能力为主要特色 1。

hwatu 在性能上相比现有解决方案有显著优势 1。页面完整验证流程（包括启动、加载、评估、截图和关闭）耗时约 35ms，比 Playwright 的 341ms 快 9 倍 1；窗口创建耗时仅 13ms 1。该工具支持无头模式，允许通过单次调用完成页面检查 1。与此同时，hwatu 的冷启动时间为 435ms，而 Playwright 为 190ms 1。

该工具已集成 MCP 协议，支持 Claude、Cursor、Jcode 等多个 AI 编码客户端 1。采用单个静态二进制文件的部署方式，文件大小远小于 Chromium 的 170MB 1。项目采用 AGPL-3.0 开源许可，目前仅支持 Linux 平台 1。一个 agent 借助 hwatu 将 Stripe.com 克隆页面的像素匹配度从 85.1% 提升到 98.8% 1。

A new verification browser called hwatu has been released, designed specifically for AI agents to streamline webpage inspection tasks 1. Developed by hongnoul, the tool emphasizes single-call verification and rapid window initialization, achieving a 13-millisecond window creation time 1.

The performance advantages over existing solutions are substantial. hwatu completes a full page verification cycle—encompassing opening, loading, evaluation, screenshot capture, and closure—in approximately 35 milliseconds, representing a ninefold speed improvement compared to Playwright's 341-millisecond duration 1. However, hwatu's cold startup time of 435 milliseconds is slower than Playwright's 190-millisecond cold start 1. The tool is built on WebKitGTK-6.0 and distributed as a single static binary significantly smaller than Chromium's 170-megabyte footprint 1.

hwatu integrates with multiple AI coding platforms including Claude, Cursor, and Jcode through MCP protocol support 1. The tool operates exclusively in headless mode and is currently available only on the Linux platform 1. It is distributed under the AGPL-3.0 open-source license 1. In a practical demonstration, an AI agent using hwatu successfully improved a cloned Stripe.com webpage from 85.1 percent pixel matching accuracy to 98.8 percent 1.
