opencode — Free, open-source AI coding agent for your terminal

Stop paying monthly for an AI wrapper. opencode runs in your terminal, connects to 75+ model providers via your own API keys, and costs exactly what you use — nothing more.

I switched from Cursor after my third renewal. The thing that finally pushed me: I realized I was paying for the tool and the model, when I already had API credits sitting unused. opencode let me plug those in directly.

A few things that actually matter in daily use:

Build vs Plan mode. Plan mode drafts what it's going to do before touching any files. Sounds small. Isn't.

Provider switching on the fly. Heavy reasoning on Sonnet, routine cleanup on something cheaper. No config change, no restart.

It's just a terminal app. No Electron, no background process, no account required to start.

One honest note: the Claude Pro/Max subscription login was removed in v1.3.0 after Anthropic pushed back. API key only now. For me that was already the plan anyway.
