Duplex v0.2.1

Duplex v0.2.1 — now for Windows, macOS and Linux

This release adds multi-platform installers and fixes three cross-platform issues (surfaced by the new automated build pipeline).

Downloads

Platform	File
Windows (x64)	Duplex.Setup.0.2.1.exe
macOS (Apple Silicon)	Duplex-0.2.1-arm64.dmg
macOS (Intel)	Duplex-0.2.1.dmg
Linux (x64)	Duplex-0.2.1.AppImage

macOS builds are unsigned — right-click the app → Open the first time. AppImage needs chmod +x before running.

Fixes

• Windows crash on exit — guarded TabManager teardown races that could crash the main process with Object has been destroyed.
• POSIX protected-path gap — ~/.ssh, ~/.aws, ~/.gnupg (and system dirs) are now refused on macOS / Linux too, not just Windows.
• Command timeout on POSIX — the timeout kill now takes down the whole process tree; previously a shell child could survive and hang the tool call.

Also in this release

• README: 14-second demo GIF (EN + 中文) and a CI badge.
• Pushing a v* tag now produces all platform installers automatically via GitHub Actions.

2026-09-29 更新 / Update

• 外部工具双向镜像：Codex / Claude Code 的会话可直接在面板中回复续聊（无头 resume 同一会话，回复实时流回面板）。
• 模型选择器：每个外部工具可在面板切换模型（默认跟随 CLI 配置），支持一键写回全局配置（自动时间戳备份）。
• 修复：安装包正确内置 MCP 桥（此前打包版的外部工具 MCP 接入不可用）；主题 / 引擎下拉类名拆分；README 同步更新。
• External agents: reply directly from the panel now (Codex exec resume / Claude Code --resume, same session, replies stream back live). Per-tool model picker with one-click write-back to the global CLI config (timestamped backup). The installer now correctly bundles the MCP bridge.

Duplex 0.1.0

First public release of Duplex - one browser shared by a human and an AI.

Highlights

• A real browser: tabs, address bar with search (Baidu / Bing / Google), themes, wallpaper start page
• 24 MCP tools for AI agents (snapshot / click / type / drag / upload / wait / evaluate / annotation_mode / ...) with a zero-setup stdio bridge
• opencode session mirror: AI messages, reasoning and tool calls stream into the side panel in real time
• AI action visualization on the page (cursor / highlight / status bar) and instant Esc takeover
• Page annotations compiled into structured text briefs - text-only AIs can see what you mean
• Built-in OpenAI-compatible agent (DeepSeek / Kimi / Qwen / GLM / Ollama) with provider management
• Full UI in Chinese and English

Windows x64 installer. After installing, see the README for connecting opencode or the built-in model. The installer is unsigned, so Windows SmartScreen may show a warning (More info -> Run anyway).
