Versions:
opencode-cc is a high-performance API proxy developed by Kiowx, built with Go and React, designed to convert OpenCode into a Claude Code-compatible format. Currently at version 1.3.2, with two versions published to date, the software falls into the developer tools and API gateway category, serving teams and individuals who want to run coding assistants against a broad range of large language model backends. The proxy exposes both the Anthropic Messages API and the OpenAI Chat Completions API externally, with each interface supporting streaming and non-streaming response modes, and it forwards incoming requests to the native protocol of the OpenCode Zen gateway. On the Zen gateway, 49 models are distributed across four distinct protocols; opencode-cc automatically routes each request to the correct protocol translator based on the target model identifier, eliminating the need for manual protocol configuration. This routing capability enables Claude Code to operate transparently on models from multiple families, including GLM, Kimi, DeepSeek, Qwen, Claude, GPT, and Gemini. Typical use cases include integrating Claude Code workflows with alternative model providers, unifying access to heterogeneous model protocols behind familiar Anthropic or OpenAI-compatible endpoints, and bridging development environments that require streaming chat completions with backends that speak different native protocols. Because the translation layer handles protocol differences automatically, client applications can continue using standard API calls while the proxy manages the conversion to and from the Zen gateway format. The software is suited to developers seeking a single, performant gateway for multi-model coding assistance, as well as organizations that need compatibility between Claude Code tooling and the broader set of models available through OpenCode Zen. Its combination of dual API surfaces, streaming support, and model-id-based automatic routing makes it a practical adapter layer for heterogeneous AI coding environments.
