What happened
- Fact The project is in developer preview and will have compatibility‑breaking changes.[1]AI
Developer preview DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
- Fact It can be run locally via npm with a web UI at http://127.0.0.1:3080.[1]AI
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch.
- Fact Source‑based builds use pnpm commands such as pnpm run build and pnpm dsh web.[1]AI
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
- Fact The GitHub repository deepseek-ai/deepseek-harness was created on 13 Aug 2026 and had 242,280 stars on 2 Oct 2026.[1]
- Fact Its description reads: “DeepSeek Harness: Everything is a Plugin.”[1]
- Fact That is 242,280 stars in 50 days, an average of 4816.0 per day.[1]
Why it matters
