# Finch vs DeepSeek Harness

DeepSeek Harness is DeepSeek's official open-source "everything is a plugin" agent framework for developers to assemble themselves; Finch is a download-and-use desktop app.

DeepSeek Harness (dsh) is DeepSeek AI's open-source agent framework, currently in developer preview, where every capability — models, tools, storage, UI — ships as a swappable plugin for developers who want to assemble their own agent runtime. Finch is a download-and-use desktop GUI app that works out of the box, with no framework to set up first.

| Aspect | Finch | DeepSeek Harness |
| --- | --- | --- |
| Publisher | Finch Toys (third party) | DeepSeek AI (official, developer preview) |
| Form factor | Desktop GUI app, ready to use after download | Local Web UI, requires self install/setup (\`npx dsh web\` or build from source) |
| Getting started | Download, install, chat in natural language | Requires a Node.js environment and plugin-based configuration |
| Focus | General-purpose desktop agent | Pluggable agent framework for harness developers |
| Extensibility | Mini tools (pluggable extensions — UI, tools, credential storage, skills, and MCP are all customizable) [Learn more →](/en/docs/minitools) | Cordis-based plugin kernel; models/tools/storage/UI are all swappable |
| Cross-session memory | Built in, retains project and personal context across sessions | No equivalent built-in cross-session memory documented; run history is recorded as a session log |
| Runtime | Local desktop app, no server required | Runs locally, requires a Node.js/pnpm dev environment |
| Pricing | The app is free, permanently | Open source and free (MIT); you cover deployment and model usage costs |
