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].
