DeepSeek Harness
In-depth plugin reviews, real-world scenario guides, and bilingual documentation — helping you make the right choices.
Why DeepSeek Harness
Not just another AI chat — a composable Agent operating system built for serious builders.
Multi-instance Concurrency
Run multiple independent Agent instances on one machine, each with different models/API keys. Built-in sub-agent delegation pushes resource utilization to the limit — ideal for complex task decomposition and batch workloads.
Everything Is a Plugin
Models, tools, skills, sessions, sandboxes, storage, loops, scheduler, UI, Agent Loop — all swappable via config, zero source-code changes. Dramatically reduces tech debt for enterprise private deployments and academic experiments.
Custom Preset Modes
Four built-in modes (Standard / PTC / Minimal / Creative) plus craft your own vertical workflows — knowledge base, docs, PPT, poster, video. One click to switch into a specialized Agent pipeline.
Fully Traceable Sessions
Unified event stream with Resume / Fork / Replay / Search. Long-running tasks can be fully replayed — compressing debug time from hours to seconds for complex chain errors.
Cross-platform, Browser-first
One command launches a local Web UI on Windows/macOS/Linux. Also supports Headless, Python SDK, and JSON-RPC — covering every role from PM visual demos to backend automation.
Other Agents as Plugins
Official bridges to Claude Code, Codex, etc. — use them directly as sub-agents. This "orchestrator" pattern solves the ecosystem gap by reusing mature tools' existing capabilities.
Dynamic Extensions + MCP Native
Load plugins at runtime; any MCP Server plugs directly into the unified tool chain. The plugin market isn't limited to DSH's own ecosystem — it's open to the entire MCP universe.
Tiered Security Sandbox
Granular permissions (read-only → full access) with OS-level sandboxing. Adapts from daily dev to benchmarking — the safety net needed to go from toy to serious production.
Model-agnostic
Supports ~40 model providers (DeepSeek / OpenAI / Anthropic / Google / Kimi, etc.) and mix-and-match freely. Full model choice freedom and seamless switching.
Fully Open Source (MIT)
Officially open-source with a fast-growing community plugin ecosystem. No vendor lock-in — the trust foundation and co-building starting point that completes the advantage chain.
