OpenCode is an open-source coding agent from the team at Anomaly that runs as a terminal UI, a desktop app, or an IDE extension. It is provider-agnostic by design: it connects to 75+ LLM providers through Models.dev, including Claude, ChatGPT plans, Gemini, GitHub Copilot logins, and local models, so you are never locked to one vendor. Standout features include LSP integration that loads the right language servers automatically, multi-session support for running parallel agents on the same project, and shareable session links for debugging. The project reports 160K GitHub stars and 900 contributors on its site, making it one of the largest open-source agent communities. If Claude Code's workflow appeals to you but you want full control over the model behind it, this is the strongest open alternative.
