Show HN: HolyCode – OpenCode in Docker. Use your Claude subscription. 30 tools (opens in new tab)

HolyCode is a Docker image that wraps OpenCode (https://opencode.ai), an AI coding agent with a web UI. It ships with 30+ dev tools pre-installed, a headless Chromium/Xvfb/Playwright stack, s6-overlay for process supervision, and UID/GID remapping for correct file permissions on bind mounts.

The main problem it solves: rebuilding the same environment every time you switch machines or update a container. All OpenCode state (sessions, settings, MCP configs, plugins) lives in a bind mount outside the container. Rebuild or update the image, your state comes back.

*On the API key cost angle:*

If you pay for Claude Max or Pro, you can use those credentials directly instead of a separate Anthropic API key. One env var enables it. The plugin reads from the credentials file OpenCode stores on your host. This removes a layer of cost if you're already paying for a subscription.

Note: this may be outside what Anthropic's ToS covers. The README is explicit about that.

It supports 10+ AI providers (Anthropic, OpenAI, Gemini, Groq, Bedrock, Azure, Ollama, and more). The Claude subscription feature is optional. Set any provider key and it works.

oh-my-openagent is also included as an optional plugin (`ENABLE_OH_MY_OPENAGENT=true`). It turns OpenCode into a coordinated multi-agent system with parallel execution and specialized agents.

Worth noting that OpenCode 1.3.0 had to remove the Claude Max plugin after Anthropic sent lawyers. The core issue was that OpenCode built its own OAuth flow to obtain subscription tokens and managed the auth themselves.

Anthropic considers that a violation because third parties aren't allowed to offer Claude.ai login for their products.

HolyCode uses a lighter approach, I think? It seems that it reads from the local credentials file that Claude Code already stores on the host. But unfortunately the underlying tension is the same.

Anthropic subsidizes $5k of compute on a $200 sub, but only wants you to use it through their own surfaces. Third-party tools that tap into those subsidized tokens, whether via custom OAuth or local credential files, are all in a gray area until Anthropic actually clarifies their policy.

Which, as of today, they still haven't...unfortunately.
