zero

Why we included this project

Zero is a terminal-first coding agent for developers who want to choose the model and decide what the agent is allowed to do. It inspects repositories, edits files, runs commands, and can use browser or terminal helpers, while storing sessions locally so they can be searched and resumed later, with nothing uploaded as telemetry. The tool supports a wide range of model providers, from OpenAI, Anthropic, and Gemini to Ollama and any OpenAI- or Anthropic-compatible endpoint. Its exec mode turns the same agent into a scriptable tool for CI, with JSON output and exit codes, while the interactive TUI handles day-to-day work. That flexibility makes it a solid fit for small teams that want to audit and own their coding agent, and MCP servers, plugins, hooks, and subagents let them extend it beyond a fixed assistant.
