Why OpenCode instead of Antigravity?

I use OpenCode so I can easily use more than just Claude all in one place. I use sub agents with grok, Gemini, and qwen coder to write code and review each others code and the output of my ai code has become orders of magnitude more reliable since doing so. Way better than just using Claude in cc alone.

Claude is my main orchestration because I enjoy interacting with it the most. I just copied the Claude code system prompt and customized it to make the prompt for my Claude agent.

Just experiment and build shit with each one and feel them out. No need to seek validation for your choice.

I will share with you my perspective : opencode is open source and no one need red-tape a company to implemented changes or make it compatible with ant other private feature. Fork it and go free. For instance, we can make it compatible with Anthropic Skills. So we can easily take advantage of any technology if we want and know how to code it. Future: you will be skilled using a tool that will receive constant updates from all sort of people around the world. Long life on edge or near edge technology. So you will spend the most precious asset you have in life on a tool which you have full control, long lifetime, and very likely will adapt to all new trends of the future compared to all competitors.

There is no top 1 coding agent. You are the coding agent

I followed this rule my entire carrier. Always use vendor agnostic open source tools. Because the issue is time investment. Because if you're going to spend time learning about all the intricacies of a tool, you don't want that to be some tool a vendor can pull the rug under you.

There is no telling which model will be best tomorrow. And OpenCode being designed from ground up to work with all of them will have the best chance at staying the single agent I use.

Also I use local models and OpenCode supports those out of the box. And finally OpenCode is great.

Using Opencode with Ohmyopencode and antigravity auth, this shit is unbelievable, given the amount of IDEs, terminal and whatever agents exists I've basically tried them all the multi agent, with LSP, combined with Opus 4.5, gemini 3 pro and gpt 5.2 makes opencode really a tool in a league of its own

To be confident you need to try it out.

The premise of the post you quoted here is wrong. There are many reasons to use open code such as good UX, frequent updates, no vendor login, pay as you go, a/b testing of models, integration of own tools or plugins, custom command creation, open source, …

Simple, antigravity expects you to pay for Gemini sub. With open code you can pretty much anything what you have. You can even set your agents to different ai suppliers, for example I am thinking using ChatGPT for planning Claude for building 

I haven’t used opencode in a while but I’ve been blown away by factory.ai droid. It’s closed sourced and has a subscription model but you can bring your own apis

The only reason why I couldn’t go with antigravity because I couldn’t connect my Claude max at the time. And the agent interface is built on top of vscode instead integrating inside vscode. I don’t want to work with multiple windows. Maybe they’ve changed it, I’ve tried it on initial release
