prompt-optimizer
Prompt Optimizer rewrites system and user prompts with an LLM you configure, then lets you test, compare and save the results as versioned favorites. It runs as a browser app, desktop app, Chrome extension or Docker container, and exposes an MCP server at /mcp with optimize-user-prompt, optimize-system-prompt and iterate-prompt tools. Model calls go straight from the client to the provider, including text-to-image and image-to-image modes.
Who it is for: Users who write and iterate on LLM prompts and want a dedicated tool
Strengths
- Ships as web app, desktop app, Chrome extension and Docker image
- Built-in MCP server at /mcp for Claude Desktop and other MCP clients
- Analysis and compare evaluation, variables, multi-turn and function-calling tests
- Client-side processing; requests go directly to the configured provider
Weaknesses
- Web version may hit browser CORS limits with local endpoints such as Ollama
- VITE_* API keys are exposed in browser assets on public deployments
- Chrome Web Store version can lag behind the latest release
- Workspace/project management is still unchecked on the roadmap
- no GPU
- Docker + Compose
- Needs LLM provider API key or compatible endpoint
- Models: OpenAI, Gemini, DeepSeek, Grok, Zhipu AI
- port 8081
dsh-desktop
DSH Desktop wraps the pinned, unmodified upstream DeepSeek Harness web UI, host service and plugin system in a native desktop app with window, tray, terminal and auto-update. The desktop shell is itself a DSH plugin, and the app includes a plugin market and phone remote control (iOS/Android, from 2.0.9). Installers cover Windows x64 and macOS Universal; no Node.js is needed.
Who it is for: Windows and macOS users who want a packaged DeepSeek Harness app with plugins
Strengths
- Installers for Windows x64 and macOS Universal, no separate Node.js install
- Runs a pinned, unmodified upstream DeepSeek Harness version
- Built-in plugin market and desktop services for third-party plugins
- Web service listens on loopback only by default
Weaknesses
- No Linux build listed
- LAN access option has no authentication, per the README
- Tied to DeepSeek Harness; independent project, not affiliated with DeepSeek
- README and docs are primarily in Chinese
