Claude Code-style terminal UI plugin for DeepSeek Harness

6.3 /10

Pricing: Open source

Pros

Very actively maintained with CI, an English/Chinese README, and official recognition from DeepSeek Harness's own channel
Rich terminal feature set: image/diagram previews (Kitty/Sixel, Mermaid), session management, VS Code companion extension, all as a zero-core-changes plugin

Cons

Hard dependency on DeepSeek Harness plus a DeepSeek API key — it is not a standalone agent
README explicitly warns the default Windows profile ships with an unrestricted-access permission mode, so review that setting before use

Our pick

OpenAI Codex edges it with a score of 9.1 versus 6.3.
