DeepSeek Harness

- ✓Local npx path, no hosted lock-in for the runtime itself
Cons
- ×Developer preview v0.1 as of August 13, 2026 — expect breakage
- ×You still pay for inference, and you assemble the stack
- ×Not a product with an SLA or a consumer UI beyond the local web mode
- ×"Rival to Claude Code" is press framing, not a documented feature-parity claim
