OpenCode just killed all vibe coding apps (it’s insane)

OpenCode is an open-source AI coding agent that runs in the terminal and supports over 70 AI models from various providers. Unlike Claude Code, it's free, allows users to bring their own API keys or subscriptions (ChatGPT, GitHub Copilot, OpenRouter), and has no vendor lock-in. The video demonstrates building five different applications using OpenCode with various models (Claude Opus, Gemini, GPT-5.2 Codex, GLM-4.7, Grok), comparing its features, UI, and performance against Claude Code. Key advantages include open-source nature, cost-effectiveness, polished CLI interface, support for agents.md convention, and the ability to use existing subscriptions without additional costs.
