DeepSeek Harness vs Claude Code
The 145k-star newcomer from DeepSeek AI vs the most battle-tested CLI agent. What the data says.
结论
Claude Code is the only harness with AgentRunDB-verified DeepSeek runs today (4 runs, 75%). DeepSeek Harness is the fastest-growing open-source alternative (145k+ stars, MIT) but is in developer preview — and AgentRunDB has not verified it yet.
| DeepSeek Harness (dsh) | Claude Code | |
|---|---|---|
| Status on AgentRunDB | Source Only | ⚠ Partial (run-verified) |
| Verified runs | 0 | 4 |
| License | MIT (open source) | Proprietary CLI |
| Architecture | Everything is a Plugin (Cordis) | Monolithic CLI + Skills |
| Maturity | Developer preview (breaking changes expected) | Production |
| Model | DeepSeek-native | Anthropic (DeepSeek via endpoint override) |
When to pick which
- Want open source + plugin ecosystem + DeepSeek-native: try dsh — it is iterating fast.
- Want verified reliability on DeepSeek today: Claude Code has the evidence trail — see the compatibility page.
