cherry-studio
Cherry Studio is a desktop app for Windows, macOS and Linux that talks to cloud providers such as OpenAI, Gemini and Anthropic, and to local models through Ollama and LM Studio. It includes 300+ preset assistants, simultaneous multi-model chats, document handling (text, images, Office, PDF), WebDAV backup and an MCP server integration. An Enterprise Edition with admin backend and shared knowledge bases is sold separately.
Who it is for: Individuals wanting one desktop client for many LLM providers and local models
Strengths
- Supports cloud providers plus local Ollama and LM Studio in one client
- Runs the same prompt against multiple models in a single conversation
- Installs as a desktop app with no environment setup, on Windows, Mac and Linux
- 300+ preconfigured assistants plus custom assistant creation
Weaknesses
- AGPL-3.0; commercial use outside AGPL terms needs a separate license
- Admin backend, team knowledge base and access control are Enterprise-only
- Plugin system, OCR, TTS and ASR are listed as roadmap items, not shipped
- No Docker or web deployment; desktop only, so no multi-user server in Community Edition
- GPU optional
- Needs Ollama or LM Studio (optional, for local models), WebDAV (optional, for backup)
- Models: OpenAI, Gemini, Anthropic, Ollama, LM Studio
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
