CodeLayers

CodeLayers is a codebase visualization tool designed to help developers understand the impact of code changes by mapping dependencies and affected files in a 3D environment. It addresses the challenges of navigating large codebases by providing spatial navigation, allowing users to see every file a change touches and the downstream effects before committing code. The platform highlights the "blast radius" of changes, using color-coded visualizations to indicate direct and indirect impacts across the codebase.

The tool is available on iPhone, iPad, and Vision Pro, with a companion CLI that runs on macOS and Linux. Developers can explore any GitHub pull request by pasting a link, instantly viewing all changed files and dependencies directly in their browser without the need to clone or check out repositories. CodeLayers also offers a VS Code extension that visualizes the blast radius of changes within the editor, providing file decorations, annotations, and a sidebar for affected files.

AI integration is a key feature, with agents that can answer questions about the codebase by highlighting relevant files and tracing dependency chains. Users can interact with AI agents across devices, sending prompts from a laptop or mobile device and approving edits remotely. The platform supports all major programming languages, including Rust, TypeScript, Python, Java, Go, C++, C, Ruby, PHP, Swift, and Zig, with plans to expand language support further.

Security is emphasized through zero-knowledge encryption. Code is encrypted locally using AES-256-GCM before leaving the user's machine, with client-side decryption and keys managed via iCloud Keychain. The backend only stores encrypted data that it cannot access, and users retain full control over their encryption keys, which are derived using the BIP-39 standard.

99 per year. An Enterprise plan is available for organizations, providing team management and priority support. The tool is positioned as a developer solution for code visualization, dependency analysis, and secure collaboration across devices.
