Download & Installation FAQ
Answers to common questions regarding client editions, API keys, system permissions, and local deployments.
How to choose between Web and Desktop editions?
The Web edition is tailored for developers who wish to customize source code, build plugins, or host private deployments across browsers. The desktop app (Windows / macOS) provides an out-of-the-box native GUI workspace with preconfigured runtime environments. Choose the best match for your daily workflow.
What is the difference between official and third-party editions?
The official open-source edition is intended for engineers building custom plugins, tools, or self-hosted systems with complete architectural freedom. The community desktop edition pre-packages runtime dependencies into a polished desktop GUI, designed for frictionless everyday productivity without manual setup.
Windows SmartScreen warning fix?
Because community desktop builds are distributed without enterprise-grade commercial code signing certificates, Windows SmartScreen may flag an unrecognized publisher. This is normal. The software is completely open-source. Click 'More info' on the blue popup window, then select 'Run anyway' to launch the installer.
macOS unverified developer error fix?
When opening non-App Store apps on macOS, Gatekeeper may display an 'unidentified developer' prompt. Go to System Settings > Privacy & Security, scroll down to the security section, and click 'Open Anyway'. Alternatively, right-click the application icon in Finder and select 'Open' to grant permanent execution access.
How to update DeepSeek Harness after installation?
The desktop client features built-in update notifications. When a new release is available, an update banner will appear allowing one-click upgrades while preserving all existing configurations. If you are using the Web source or CLI edition, simply execute git pull or npm update in your workspace directory to fetch the latest commits with complete data persistence.
Support local LLMs and private endpoints?
Yes, fully supported. DeepSeek Harness complies strictly with standard OpenAI API protocols. In addition to official cloud APIs, you can redirect the client BaseURL to locally hosted Ollama, vLLM, LM Studio, or internal enterprise gateways, enabling offline execution with complete data sovereignty.
