Question 1

Can CodeLayers see my source code?

Accepted Answer

No. CodeLayers uses zero-knowledge encryption. Your code is encrypted on your device before it ever reaches our servers. We cannot read your code, and we never will.

Question 2

What languages does CodeLayers support?

Accepted Answer

CodeLayers supports TypeScript, JavaScript, Python, Rust, Go, Java, C++, C#, Ruby, PHP, and Swift. We use tree-sitter for accurate parsing.

Question 3

What devices does CodeLayers support?

Accepted Answer

CodeLayers is available on iPhone, iPad, and Apple Vision Pro. The CLI tool runs on macOS with Apple Silicon for code parsing and sync.

Question 4

What is blast radius analysis?

Accepted Answer

Blast radius shows the impact of code changes by visualizing which files and functions are affected when you modify code. Files are color-coded by distance from the change.

Question 5

What is CodeLayers Explore?

Accepted Answer

CodeLayers Explore lets you visualize any public GitHub pull request in 3D — no clone, no checkout, no account needed. Just paste a PR link or run 'codelayers explore <URL>' and see the full architecture in your browser instantly.

Question 6

How many PRs can I explore for free?

Accepted Answer

You get 10 free PR explores every 30 days. Each explore gives you a full 3D visualization of the pull request's architecture, changed files, and blast radius.

Question 7

How do I visualize my codebase in 3D?

Accepted Answer

Install the CodeLayers CLI on macOS with 'brew install codelayers-ai/tap/codelayers', run 'codelayers sync' in your repo, then open the CodeLayers app on iPhone, iPad, or Apple Vision Pro. Your codebase appears as an interactive 3D scene where files are nodes and imports are connections.

Question 8

How do I see the impact of a code change before merging?

Accepted Answer

Use blast radius analysis in CodeLayers. Select any file and see which other files would be affected if it changes. Files are color-coded by distance — red for directly impacted, fading to blue for indirectly affected. You can also use CodeLayers Explore to visualize a GitHub pull request and see the blast radius of every changed file.

Question 9

What tools help me understand a legacy codebase?

Accepted Answer

CodeLayers helps you navigate unfamiliar codebases by rendering the entire dependency graph in 3D. You can spatially explore the architecture, see which files are foundational (low topological depth) versus surface-level, trace dependency chains visually, and chat with AI about specific files or patterns in your code.

Question 10

Can I use AI assistants with CodeLayers?

Accepted Answer

Yes. CodeLayers gives Claude Code, Gemini CLI, and Codex 14 MCP tools for graph-enriched search, call chain tracing, type flow analysis, and 3D visualization control. The agent highlights files, traces dependencies, and checks blast radius in your 3D graph as it works.

Question 11

How do I visualize a GitHub pull request?

Accepted Answer

Use CodeLayers Explore. Paste any public GitHub PR URL into the Explore tab in the app, or run 'codelayers explore <PR-URL>' from the CLI. You'll get a full 3D visualization of the PR's architecture, changed files, and blast radius — no clone or checkout needed. You get 10 free explores every 30 days.

Question 12

Is CodeLayers free?

Accepted Answer

CodeLayers offers a free tier that includes 10 public PR explorations per month via CodeLayers Explore, plus a completely free VS Code extension for blast radius analysis in your editor. For private repository sync, AI chat features, overlays, and unlimited explorations, CodeLayers Pro is available as a subscription.

Question 13

Does CodeLayers have a VS Code extension?

Accepted Answer

Yes. The CodeLayers — Blast Radius extension for VS Code is completely free. It shows the blast radius of your code changes directly in your editor with color-coded file decorations, CodeLens annotations, and a sidebar showing affected files by hop distance. No account or subscription required — install from the VS Code Marketplace and start seeing the impact of every change.

Question 14

What is topological depth in a codebase?

Accepted Answer

Topological depth measures how deep a file sits in your dependency graph. Foundation files at depth 0 are imported by others but import nothing themselves — they are your most critical infrastructure. Higher layers build on lower layers, forming a natural pyramid shape. Changes to low-depth files have the largest blast radius.

Question 15

Does CodeLayers work on iPhone and iPad?

Accepted Answer

Yes. CodeLayers runs on iPhone (iOS 18+), iPad (iPadOS 18+), and Apple Vision Pro (visionOS 2+). The same 3D code visualization experience adapts to each device — pinch to zoom on iPad, swipe through layers on iPhone, or walk through your architecture in spatial computing on Vision Pro.

Question 16

How does CodeLayers keep my code private?

Accepted Answer

CodeLayers uses zero-knowledge encryption. Your source code is encrypted on your device using AES-256-GCM before it ever leaves your machine. The encryption key never touches our servers. We physically cannot read your code — only your device can decrypt it.

Question 17

Can I add CodeLayers to my CI/CD pipeline?

Accepted Answer

Yes. The CodeLayers GitHub Action automatically generates 3D code visualizations for every pull request. Add it to your workflow and each PR gets a visualization link posted as a comment, so reviewers can explore the architecture before approving.
