About

DeepSeek Harness is an open source agent harness designed to keep AI agents working in real-world environments by helping them understand context, use tools, and continue operating across complex tasks. Built on the Cordis plugin system, every capability is a plugin that can be selected, swapped, extended, or recomposed through configuration without changing the core source code. Plugins provide models, tools, skills, sessions, sandboxes, storage, loops, scheduling, and the UI, while Cordis manages plugin mounting, dependencies, services, and events. Every run is traceable through an append-only session log that records system prompts, reasoning, tool calls and results, subagent scheduling, and context injections. The Trajectory view lets developers inspect these records by source, while resume, fork, search, and replay operate on the same event stream.

About

OpenCode is the AI coding agent purpose-built for the terminal. It delivers a responsive, themeable terminal UI that feels native while streamlining your workflow. With LSP auto-loading, it ensures the right language servers are always available for accurate, context-aware coding support. Developers can spin up multiple AI agents in parallel sessions on the same project, maximizing productivity. Shareable links make it easy to reference, debug, or collaborate across sessions. Supporting Claude Pro and 75+ LLM providers via Models.dev, OpenCode gives you full freedom to choose your coding companion.

Pros & Cons from Real Users

Pros

  • OpenCode feels like a strong fit for developers who want an AI coding agent without getting locked into one model or one editor. I like that it works in the terminal, desktop, and IDE, so it can fit into different workflows instead of forcing one setup. The model flexibility is a big win. Being able to use 75+ providers, local models, GitHub Copilot, or ChatGPT Plus/Pro makes OpenCode feel more open and customizable than a lot of coding assistants. I also like the LSP support and multi-session workflow. For real coding work, it helps when the agent understands the project better and can run multiple threads of work in parallel.
  • Easy to install Easy to use Free models available with nearly no limits New models commonly get added for free

Cons

  • OpenCode is still something I would supervise closely. Any coding agent that can modify files, reason through projects, and run workflows needs clear review, tests, and good developer judgment.
  • CLI only
