OpenCode – Open source AI coding agent
The free desktop app connects to 75+ LLM providers and works in your terminal, IDE, or as a standalone app.
OpenCode has officially launched its open-source AI coding agent into public beta, making a cross-platform desktop application available for macOS, Windows, and Linux. The project, which boasts an impressive 120,000 GitHub stars and contributions from 800 developers, is already used by over 5 million developers monthly. Its core value proposition is flexibility: users can leverage free, built-in models or connect to any external large language model (LLM) from over 75 providers, including major players like Anthropic's Claude, OpenAI's GPT, and Google's Gemini via the Models.dev platform. This model-agnostic approach, combined with a strict privacy policy that ensures no user code or context is stored, positions it as a versatile and secure tool for professional development environments.
The agent is designed to integrate seamlessly into existing workflows, available as a terminal interface, a desktop application, and an IDE extension. Key features include automatic Language Server Protocol (LSP) loading for the connected LLM, the ability to run multiple agent sessions in parallel on the same project, and session sharing via links for collaboration or debugging. Crucially, it supports existing AI subscriptions, allowing developers to log in with their GitHub account to use Copilot or with OpenAI to utilize a ChatGPT Plus/Pro subscription, potentially lowering the barrier to entry. For teams seeking optimized performance, OpenCode also offers 'Zen'—a curated set of handpicked and benchmarked models specifically validated for coding agent tasks to ensure consistent quality.
