Show HN: DeepSeekGUI – A Windows desktop client for DeepSeek's coding agent

See-Sol-Lab released DeepSeekGUI v1.0.0, a Windows desktop client that packages DeepSeek's Harness coding agent into a native app with an installer, system tray, built-in browser, and terminal. The tool requires only an installer and a DeepSeek API key, runs sandboxed with user approval for file edits and tool actions, and stores all data locally. It is not an official DeepSeek product, and a fully independent workbench is planned for v2.0.0.

English | 中文 /See-Sol-Lab/DeepSeekGUI/blob/main/README.zh.md DeepSeek's coding agent, on your desktop. A Windows desktop client for DeepSeek Harness https://github.com/deepseek-ai/deepseek-harness . DeepSeekGUI packages the DeepSeek Harness https://github.com/deepseek-ai/deepseek-harness Web UI into a native Windows app. V1 runs the official Harness interface inside a desktop shell, with added integration — installer, system tray, built-in browser and terminal. Point it at a folder, give the agent a task, and it reads your code, edits files, runs commands, browses the web, and explains what it did — all through DeepSeek's models. Just the installer and an API key — everything else is bundled. Not an official DeepSeek product. Built on top of DeepSeek Harness but independently developed. The upstream runtime and official Web UI are DeepSeek's work. Where this is headed:V1 is a desktop wrapper around the upstream Web UI. A fully independent workbench with a custom interface built for desktop is in active development and expected to ship asv2.0.0. | Platform | Download | Requirements | |---|---|---| | Windows | | Installs to your user account — just double-click. The installer bundles its own runtime, ready to go. Verify the download recommended V1 isn't code-signed yet, so Windows SmartScreen will warn about an unknown publisher. Verify the installer hash before running it: gh release download --repo See-Sol-Lab/DeepSeekGUI --pattern 'DeepSeekGUI-Setup- .exe' --pattern 'SHA256SUMS.txt' --clobber Get-FileHash .\DeepSeekGUI-Setup-1.0.0.exe -Algorithm SHA256 Only run the installer if the hash matches SHA256SUMS.txt https://github.com/See-Sol-Lab/DeepSeekGUI/releases/download/v1.0.0/SHA256SUMS.txt . See the troubleshooting guide /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/data-troubleshooting.md windows-smartscreen-blocks-the-installer if you get stuck. - Install DeepSeekGUI and open it. - Go to Settings → Models and paste your DeepSeek API key. - Pick a model choose one with vision support if you need image input . - Go back to the home screen and open a workspace folder. - Start a session, tell the agent what you want, and review its work. See the quick-start guide /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/quickstart.md for a full walkthrough. It's a real app. One-click install — bundles its own runtime, so all you need is the installer. Built for DeepSeek. DeepSeek reasoning, vision, and tool use each have dedicated product paths. You stay in control. The agent runs sandboxed by default. Every file edit and tool action needs your approval before it happens. You see what it's doing, and you can stop it. A real, visible browser. The built-in browser panel uses Edge — you can watch the agent navigate in real time. Sensitive actions still go through approval. Everything stays on your machine. Sessions, credentials, and settings are all stored locally. Still Harness under the hood. Profiles, plugins, hooks, and the CLI all work the same way. DeepSeekGUI wraps the runtime and keeps full compatibility. Give the agent a task and watch it work through your codebase — editing files, running commands, explaining each step. Attach screenshots or images. Vision-capable models will describe and work with them. The agent can browse the web in a visible Edge window. You see every page it visits. Configure models, manage plugins, and switch between Harness profiles from one place. Windows installer — one-click setup, installs per-user. Also available as a portable build. DeepSeek + custom models — connect any OpenAI-compatible provider alongside DeepSeek. Text and image input — attach screenshots to vision-capable models. Workspace sessions — pick a folder, start coding, come back later. Built-in browser — the agent browses with visible Edge, right where you can watch. Plugin support — install and manage Harness-compatible plugins from the app. Sandbox by default — every tool call needs your approval unless you opt into full access. Built-in terminal — run Harness CLI commands in its own isolated environment. Bilingual — full Chinese and English interface. System tray — minimize to tray, check for updates. V1.0 targets Windows x64. SmartScreen will warn until code signing ships. macOS, Linux, and accounts come later. | Version | Status | What changes | |---|---|---| v1.0 | Released | Desktop wrapper around the official Harness Web UI, with installer, system tray, built-in browser and terminal. | v2.0 | In development | Fully independent workbench — custom UI built from scratch for desktop, replacing the upstream Web UI entirely. | | Guide | | |---|---| | Models and vision /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/models.md Workspaces and sessions /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/workspaces-sessions.md Profiles and plugins /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/profiles-plugins.md Permissions /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/permissions.md Desktop tools /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/desktop-tools.md Data and troubleshooting /See-Sol-Lab/DeepSeekGUI/blob/main/docs/user/deepseekgui/data-troubleshooting.md The docs also include upstream Harness tutorials and plugin-authoring reference. All your data stays local in %APPDATA%\DeepSeekGUI\dsh — credentials, settings, sessions, everything. The only network traffic goes to your configured model provider. Logs automatically redact anything that looks like a credential. Diagnostics stay local. When you uninstall, the app asks whether to keep or remove your data.
