How to Become an OpenCode Expert: Master the Open-Source Alternative to Claude Code OpenCode, the open-source coding agent, crossed 165,000 GitHub stars in 2026 and became the most-used open-source coding agent, with monthly active developers ranging from 2.5 million in February to over 7 million by June. The article outlines a ten-stage path to mastering OpenCode, covering agent modes, multi-provider models, MCP, and the current Claude subscription situation, emphasizing that its provider neutrality across 75-plus AI providers makes it harder to write a single tutorial compared to vendor-specific tools like Claude Code.
