DeepSeek Harness

Coding · free

Pros

  • MIT-licensed; you can read and fork the loop
  • Plugin model means you are not stuck on DeepSeek weights
  • Launched next to V4-Pro, so the vendor's own agent scores have a named runtime
  • 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
