[!NOTE]

We're building a fully productized version of Sisyphus to define the future of frontier agents. Join the waitlist here.

[!TIP]

The Orchestrator is now available in beta. Use oh-my-opencode@3.0.0-beta.10 to install it.

This is coding on steroids—oh-my-opencode in action. Run background agents, call specialized agents like oracle, librarian, and frontend engineer. Use crafted LSP/AST tools, curated MCPs, and a full Claude Code compatibility layer.

Claude OAuth Access Notice

TL;DR

Q. Can I use oh-my-opencode?

Yes.

Q. Can I use it with my Claude Code subscription?

Yes, technically possible. But I cannot recommend using it.

FULL

As of January 2026, Anthropic has restricted third-party OAuth access citing ToS violations.

Anthropic has cited this project, oh-my-opencode as justification for blocking opencode.

Indeed, some plugins that spoof Claude Code's oauth request signatures exist in the community.

These tools may work regardless of technical detectability, but users should be aware of ToS implications, and I personally cannot recommend to use those.

This project is not responsible for any issues arising from the use of unofficial tools, and we do not have any custom implementations of those oauth systems.

Reviews

"It made me cancel my Cursor subscription. Unbelievable things are happening in the open source community." - Arthur Guiot

"If Claude Code does in 7 days what a human does in 3 months, Sisyphus does it in 1 hour. It just works until the task is done. It is a discipline agent." — B, Quant Researcher

"Knocked out 8000 eslint warnings with Oh My Opencode, just in a day" — Jacob Ferrari

"I converted a 45k line tauri app into a SaaS web app overnight using Ohmyopencode and ralph loop. Started with interview me prompt, asked it for ratings and recommendations on the questions. It was amazing to watch it work and to wake up this morning to a mostly working website!" - James Hargis

"use oh-my-opencode, you will never go back" — d0t3ch

"I haven't really been able to articulate exactly what makes it so great yet, but the development experience has reached a completely different dimension." - 苔硯:こけすずり

"Experimenting with open code, oh my opencode and supermemory this weekend to build some minecraft/souls-like abomination." "Asking it to add crouch animations while I go take my post-lunch walk. [Video]" - MagiMetal

"You guys should pull this into core and recruit him. Seriously. It's really, really, really good." — Henning Kilset

"Hire @yeon_gyu_kim if you can convince him, this dude has revolutionized opencode." — mysticaltech

Oh My OpenCode

Claude Code is great. But if you're a hacker, you'll fall head over heels for OpenCode. START WITH YOUR ChatGPT, Claude, Gemini SUBSCRIPTIONS. OPENCODE COVERS THEM ALL.

• Endlessly extensible. Endlessly customizable.
• Zero screen flicker.
• LSP, linters, formatters activate automatically per file—and you can tweak everything.
• Mix and match models. Orchestrate them by purpose.
• Feature-rich. Beautiful. The terminal doesn't choke. High performance.

Remember the first time you switched from Windows to Linux? That rush of configuring everything exactly how you wanted? In an age where that magic seems lost, OpenCode brings it back. If you love coding and computers, OpenCode is that Linux-after-Windows moment.

But here's the catch: there's a lot to learn, it's complex, and your time is expensive.

I've fixed that. Even if you're not a hacker, invest a few minutes. Multiply your skills and productivity. Hand this doc to an agent and let them set it up.

It's the Age of Agents

• Just paste this link into Claude Code / AmpCode / Factory Droid / Cursor and ask it to explain.
  • Ask why it's good, why it's not just another boilerplate setup, what actually gets better.
  • If you're an LLM agent, explain to the user what becomes possible right now with this project.

As following:

Hey please read this readme and tell me why it is different from other agent harness? why is this actually good? https://raw.githubusercontent.com/code-yeongyu/oh-my-opencode/refs/heads/dev/READM
