What it does

DeepSeek 免费网页版分屏插件:本地反向代理 + DSH 内 iframe 面板,不打断当前任务。| DeepSeek web split: local reverse proxy + in-DSH iframe panel.

✅
Our take
Works — verified, early-stage project

DeepSeek 免费网页版分屏插件:本地反向代理 + DSH 内 iframe 面板,不打断当前任务。| DeepSeek web split: local reverse proxy + in-DSH iframe panel. It installs cleanly and boots without issues in our testing. It's early-stage but functional.

“Verified” means our automated CI actually ran dsh plugin add in a clean profile and it booted — nothing more. Feature descriptions and version compatibility are the author’s claims. This is not a security audit and not an endorsement of third-party code.

README

dsh-web-split

DeepSeek 免费网页版分屏插件:在 DSH 界面右侧以 iframe 面板打开 chat.deepseek.com 网页版,不打断当前任务。

安装

dsh plugin --profile web add /path/to/dsh-web-split

使用

  • 侧边栏底部 / 会话头部的鲸鱼按钮:开/关右侧分屏面板;
  • Ctrl / 中键点击按钮:在新标签页打开网页版;
  • 面板头部:✕ 关闭、「新标签页 ↗」备用入口。

原理

chat.deepseek.com 发送 content-security-policy: frame-ancestors 'none',浏览器拒绝 iframe 嵌入。
本插件在本地启动一个 Node 反向代理(经 shell 服务,heredoc 传脚本):

  • 剥掉 content-security-policy / x-frame-options / HSTS;
  • 改写 cookie(Domain/Secure/SameSite)适配本机同域;
  • fe-static.deepseek.com 资源改走 /festatic 同源路径,并剥掉 SRI/crossorigin
    (CDN 的 CORS 只放行 *.deepseek.com,否则脚本跨域加载失败);
  • 给 main.js 打环境补丁:让 127.0.0.1 命中 production 分支
    (原 switch(location.hostname) 对未知主机名直接 throw,导致"页面资源加载异常");
  • SSE 流式透传,聊天流式输出不受影响。

代理端口固定为 127.0.0.1:8799(冲突时回退 8800-8810 并自动回收孤儿代理),
经 webServer 路由 /dsw-proxy-port 暴露给客户端。
固定端口保证 iframe origin 稳定,因此 DeepSeek 网页版的登录态(localStorage)
在 DSH 重启后仍然保留,无需重复登录。

已知限制

  • 依赖 DeepSeek 网页版的页面结构,官方改版或收紧风控后可能需要更新;
  • 登录验证码需在面板内正常操作;聊天接口若被 WAF 限流(Rate Limit Reached)
    是 IP 级风控,稍后重试或直接用官方网页版确认。

Install

🧩 Let your agent install it (recommended)

Install the catalog once, then DeepSeek Harness can find and install any plugin from this site automatically:

dsh plugin add dshbase-catalog

Then say "install dsh-web-split for me" — your agent finds it in the directory and installs it. Docs: dshbase-catalog · verified packs.

This plugin is GitHub source (not published to npm) — install it straight from the repo:

Web profile:

dsh plugin --profile web add github:XPQHyue/dsh-web-split

Headless (CLI) profile:

dsh plugin --profile headless add github:XPQHyue/dsh-web-split
