OpenCode
Open-source coding agent for the terminal, IDE, desktop, and browser, bring your own model.
Open-source coding agent for the terminal, IDE, desktop, and browser — bring your own model.
An open-source, model-agnostic coding agent you can run anywhere and point at any model — a self-hostable alternative to closed agents.
About OpenCode
OpenCode is an open-source coding agent that runs from the terminal, a desktop app, an IDE extension, or the browser, letting developers delegate coding tasks while choosing their own model provider and API key. It reached roughly 120,000 GitHub stars in 2026 as a model-agnostic, self-hostable alternative to closed coding agents, with an optional usage-based hosted plan for those who don't want to bring keys.
OpenCode is the open, bring-your-own-model answer to the closed coding agents — and its GitHub traction shows the appetite for it. If you want a coding agent you can self-host, point at any model, and avoid lock-in, it's the strongest option; you trade the polish and managed convenience of the closed tools for control and cost flexibility.
