opencode is an open-source AI coding agent built for the terminal. It features a native TUI, multi-session support, and is model-agnostic, letting you use Claude, OpenAI, Google, or even local models.

Model-agnostic design is a strong differentiator, being able to swap between Claude, OpenAI, Gemini, or local models without lock-in is genuinely useful
Native TUI feels right for a terminal tool; it respects the environment it lives in rather than fighting it
Multi-session support is a practical win for developers juggling multiple contexts
Open-source means the community can audit, extend, and self-host it

The tool is still relatively new, so context window management and large codebase

navigation likely need more polish

No mention of agentic loop controls (e.g., approval modes, auto-apply guardrails) trust and safety mechanisms matter a lot for an agent that writes code
Terminal-first UX limits accessibility; there's no IDE extension path mentioned, which narrows the audience
"Model-agnostic" is only as strong as the abstraction layer, if switching models silently degrades quality (e.g., tool-use inconsistencies), users may not notice until it's a problem

OpenCode became part of PortAura’s day-to-day development loop, helping me inspect the project, make changes, debug issues, and iterate quickly while keeping the final decisions and validation in my hands.

worked for me as a 2nd powerhouse - great alternative really and nice ui.

It's a good tool for AI coding. I like that it's not too complicated and that it offers free models, while also allowing users to integrate models from other providers.

Configuration is a bit cumbersome with jsonc files, but it's not too bad.

The system prompt does not contain any major distortions and is not intended to alter the models' identities or capabilities.

I’ve just tried out opencodes zen recently, it’s one of the simplest and fastest setups I’ve come across in a while, for working with LLMs in the terminal. The "TUI" feels super clean and intuitive, no fussing around, just install, configure and start using it. (waiting for its support on the Bun runtime though)

opencode now integrates with vscode, cursor, windsurf, etc it'll be aware of what file you're in and you can easily send inject selected lines into the prompt start opencode inside your editor and it'll install the extension

Tried opencode and it seems to be super responsive and smart without being intrusive. I love that I can plug in any model I want. It actually feels like coding with a helpful partner in the terminal.
