What is CodeZero?

CodeZero is a VS Code extension that helps developers and coding agents understand existing software before making changes.

It builds context across repositories connected to an organisation, so developers are not limited to the repository currently open in VS Code.

CodeZero works alongside tools such as Claude Code, Codex, and GitHub Copilot rather than replacing them. Its role is to give developers and coding agents better software context before implementation begins.

Code Graph

Code Graph shows how repositories, modules, files, dependencies, and data relationships connect across the wider system. It helps developers answer questions such as what depends on a component, where a capability is implemented, whether a flow crosses repository boundaries, and what may be affected by a change.

Feature Mapping

Feature Mapping narrows that wider context to one functional area. It helps trace where a feature begins, which files participate in the implementation, what it depends on, and how the flow moves through the codebase.

Investigation and planning

Developers can use CodeZero to investigate unfamiliar code, understand dependencies, inspect Git history, and review the likely impact of a proposed change. For development work, CodeZero can help turn that investigation into a structured implementation plan before execution starts.

When a repository exists locally, CodeZero can use the current working tree. Other indexed repositories can still provide read-only context without requiring every repository to be cloned locally.

CodeZero is built for developers, senior engineers, technical leads, and teams working with complex or multi-repository codebases.
