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.
if u are interested with this ， try to quick start opencode

Is there a learning curve in the beginning?
Hello Aria
Terminal-native coding agent that’s free and open source? That’s going to become a default tool for a lot of developers who don’t want to be locked into an IDE plugin ecosystem.
The open-source angle is particularly meaningful right now — there’s a real wave of developers who want to inspect what’s happening under the hood when an AI touches their code. We’ve seen a similar "trust through transparency" dynamic in the AI personal assistant space with Hello Aria (our day management AI on WhatsApp/iOS) — users want to understand what the AI is doing on their behalf, not just trust a black box.
Opencode in the terminal is just the right UX for devs who live there. Would love to see integrations with tmux layouts down the line. What LLMs are supported out of the box?
Do you miss anything important from cursor after switching?
