Open Code is an open-source AI coding agent designed to help developers understand, change, and ship code. Created by the team at SST, it operates primarily in the terminal, but also has desktop and IDE extension options. It facilitates code generation, debugging, refactoring, and documentation. Unlike many AI coding tools, Open Code is provider-agnostic, allowing users to connect to various language models, including Claude, OpenAI, Google's models, and local models. This gives developers flexibility and avoids vendor lock-in.
Key features include LSP support for code intelligence, a terminal-first design, and a client-server architecture that allows users to interact with it from different clients. Open Code emphasizes privacy by keeping code and context local. It can be used to triage issues, fix and implement features, and automate code review. Open Code has two built-in agents: a build agent for development work and a plan agent for analysis and code exploration.
Open Code offers a free, open-source core version. For advanced features and optimized performance, users can access the Zen service for $20 per month, which offers enhanced models charged at a pay-per-use rate. Open Code is available for installation on Mac, Windows, and Linux via a universal install script, npm, or Homebrew.
