Can CodeLayers see my source code?

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.

What languages does CodeLayers support?

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

What devices does CodeLayers support?

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

What is blast radius analysis?

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.

What is CodeLayers Explore?

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 ' and see the full architecture in your browser instantly.

How many PRs can I explore for free?

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.

How do I visualize my codebase in 3D?

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.

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

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.

What tools help me understand a legacy codebase?

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.

Can I use AI assistants with CodeLayers?

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.

How do I visualize a GitHub pull request?

Use CodeLayers Explore. Paste any public GitHub PR URL into the Explore tab in the app, or run 'codelayers explore ' 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.

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.

Does CodeLayers have a VS Code extension?

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.

What is topological depth in a codebase?

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.

Does CodeLayers work on iPhone and iPad?

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.

How does CodeLayers keep my code private?

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.

Can I add CodeLayers to my CI/CD pipeline?

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.

Now on iPhone and iPad

We built CodeLayers for Vision Pro first. Spatial computing felt like the right way to explore code — walk through your architecture, reach out and grab a module, see dependencies in every direction.

But not every moment calls for a headset. Sometimes you're on the couch reviewing a PR. On a train thinking through a refactor. At your desk with your iPad propped up next to your monitor.

CodeLayers is now available on iPhone and iPad. Same 3D visualization. Same zero-knowledge privacy. Plus a set of features we've been wanting to ship for a long time.

iPad

The iPad experience is built around a split-view layout — your 3D graph on one side, a resizable chat panel on the other. File browser, node inspector, and AI agent chat all live side by side.

Landscape-optimized with Apple's Liquid Glass design language. It feels native because it is.

"Your codebase and your AI agent, on the same screen."

iPhone

On iPhone, you get swipeable Chat and Graph tabs with a floating tab switcher. Flick between your visualization and your AI conversation without losing context.

The big addition: Chat Mode. Open an AI session without loading a graph at all. Perfect for when you're on the go and just need to think through a problem with your agent.

Remote AI Agents

Run codelayers watch --agent claude on your dev machine. Then open CodeLayers on your phone or iPad and send prompts remotely.

Works with Claude Code, Gemini CLI, and Codex
Watch tool calls, file edits, and agent activity stream in real time
Approve permissions remotely — no need to walk back to your laptop
Sessions sync and persist end-to-end encrypted — pick up where you left off

You're at lunch. You remember something you wanted to refactor. Pull out your phone, send the prompt, watch the agent work. Approve the file writes. Done.

Live Activity support means you can track your agent's progress right from your Lock Screen and Dynamic Island — see what it's doing without even opening the app.

Share any synced repo as an encrypted visualization link. Recipients can explore your 3D graph without access to your source code. Architecture without exposure.

For PRs, it gets better: see the blast radius of every change, walk through commits with function-level diffs, and understand impact before you review a single line.

"Show them the shape of your code, not the code itself."

Explore

No CLI setup needed. No repo to clone.

Paste any public GitHub repo or PR URL and CodeLayers visualizes it instantly. Browse featured community repos to see how popular projects are structured — Rust, Go, TypeScript, Swift, and more.

For PRs, use the commit slider with blast radius analysis — scrub through each commit and watch the impact ripple through the codebase.

GitHub Action

Automate it. The CodeLayers GitHub Action (codelayers-ai/codelayers-action@v1) generates a 3D visualization for every PR and posts a comment with an interactive share link. Free for open source, no API key needed.

- uses: codelayers-ai/codelayers-action@v1

Every PR gets a visual blast radius — reviewers see which files are affected and how changes ripple through the codebase before reading a single line of code. The comment updates automatically when you push new commits.
