OmniRoute + OpenCode Setup 100% FREE Unlimited AI Coding (2026 Tutorial)

About This Video

Learn how to set up OmniRoute inside OpenCode and unlock 100% free, unlimited AI coding — no credit card, no API key required to get started. In this step-by-step 2026 tutorial, I show you exactly how to install OmniRoute, connect it as a custom provider in OpenCode, and route your coding agent across 339+ AI providers (90+ with free tiers, 56 free forever) including Claude, GPT, Gemini, DeepSeek, Kimi, and GLM — all through a single OpenAI-compatible endpoint. OmniRoute is a free, open-source MIT-licensed AI gateway that sits between OpenCode and every major model provider. Instead of hitting rate limits or paying for expensive API keys, OmniRoute auto-fails over between providers in milliseconds, drains your free-tier quotas before touching paid ones, and even compresses tool output by up to 95% so your tokens go further. Once it's running locally on port 20128, you point OpenCode's provider config at it and every model on the OmniRoute catalog becomes available inside your terminal coding agent. What you'll learn in this video: how to install Node.js and npm if you don't already have them, how to install OpenCode and OmniRoute globally with a single npm command, how to start the OmniRoute server and open its local dashboard, how to connect free providers with zero configuration, how to edit your OpenCode config file (~/.config/opencode/opencode.json) to add OmniRoute as a custom provider using the @ai-sdk/openai-compatible adapter, and how to pick between model routes like auto, auto/coding, auto/fast, and auto/cheap depending on whether you want quality, speed, or cost savings. This setup works as a genuinely free alternative to paying for Claude Code, Cursor, GitHub Copilot, or standalone API keys from OpenAI, Anthropic, or Google — making it ideal for developers, students, and anyone experimenting with AI-assisted coding on a budget.
