Oh My Coding Maas Gateway

oh-my-coding-maas-gateway

LiteLLM proxy routing Huawei MaaS models to opencode, Codex CLI, Claude Code CLI, and Pi agent — with virtual keys, multi-key load balancing, dual-format endpoints, and Prometheus + Grafana observability.

What Is This?

A self-hosted gateway that sits between your coding tools and Huawei ModelArts MaaS, giving you load balancing, virtual keys, budget tracking, and observability — all through a single local proxy.

Install

The bootstrap script is the only installation method. It handles everything — prerequisites, Docker stack, coding tools, virtual keys, validation, and optional companion skill.

curl -fsSL https://raw.githubusercontent.com/wallacelw/oh-my-coding-maas-gateway/main/scripts/bootstrap.sh | bash

Bootstrap will prompt for your Huawei MaaS API key, show an interactive menu to select which coding tools to install, auto-install prerequisites, deploy the proxy + observability stack, configure each tool with its own virtual key, run validation, and offer to install the companion skill.

Estimated time: ~5 min fresh, ~2 min upgrade. For flags and non-interactive usage, see [INSTALLATION.md](./INSTALLATION.md).

After install

opencode          # or:  codex  or:  claude --bare  or:  pi
