MapMyCode v1.0 is live on the VS Code Marketplace. Install free

Understand any codebase
in minutes, not days

MapMyCode is a VS Code extension that scans your workspace, maps every file relationship into an interactive dependency graph, and gives you AI-powered file summaries and a live codebase Q&A — all on your own API key, zero telemetry, no account required.

Features

Everything you need to navigate
an unfamiliar codebase

Visual Dependency Graph

Interactive force-directed canvas graph showing every file and its import connections. Click nodes for details, double-click to open the file directly.

AI File Summaries

Every key file gets a plain-English explanation of what it does, what it exports, and what it depends on. No more guessing where things live.

Codebase Q&A

Ask anything in plain English. The AI has full repo context and answers with specific file references. Multi-turn conversation with history.

5 AI Providers

Groq, Ollama, Gemini, Anthropic, OpenAI. Type any custom model name. Switch providers anytime without re-analyzing.

Analysis History

Every analysis saved locally per workspace. Load past analyses, compare graphs across refactors, delete when done.

Smart Filtering

Auto-skips node_modules, dist, build, lockfiles, minified files, and generated code across all languages. Only your source code gets analyzed.

How it works

Four steps from zero
to full understanding

The entire pipeline runs locally. The only external call is to the AI provider you configure.

  1. Scan the workspace

    Reads all source files. Automatically skips node_modules, dist, build outputs, lockfiles, minified and generated code across all languages.

  2. Build the dependency graph

    Extracts every import per language, resolves relative and alias paths, builds a node-edge map of the entire codebase.

  3. Generate AI summaries

    Sends batches to your AI provider. Returns a repo overview, architecture description, tech stack, and per-file explanations.

  4. Ask anything

    The Q&A agent has full graph, summary, and file context. Multi-turn conversation with history so questions build on each other.

AI Providers

Your key. Your choice.

Start free with Groq or run 100% offline with Ollama. All providers support custom model names.

Provider Cost Default Model Best for
Groq Free tier llama-3.3-70b-versatile Best starting point. Fast, generous free limits.
Ollama 100% Local llama3.2 Complete privacy. No internet after setup.
Google Gemini Free tier gemini-1.5-flash Good free quota. Fast and accurate.
Anthropic Claude Paid claude-haiku-4-5 Highest quality summaries and answers.
OpenAI Paid gpt-4o-mini Reliable, cost-effective at mini tier.

All providers support custom model name input.

Your code never
leaves your machine

MapMyCode has no backend. No server, no account, no database, no usage tracking. The only network request is to the AI provider you configure.

Encrypted key storage

API keys stored in VS Code's SecretStorage using OS keychain. Never written to disk in plaintext.

Zero telemetry

No analytics, no crash reports, no usage events. The extension works fully offline except for AI calls.

Open source and auditable

Every line of code is public on GitHub. Read it, verify it, fork it.

FAQ

Common questions

Is MapMyCode free?

Yes — completely free and MIT-licensed. You bring your own API key from Groq (free tier) or Ollama (fully local). No subscription, no account.

Does my code get sent to a server?

No. MapMyCode has no backend. The only external call is to whichever AI provider you configure. Your code stays on your machine.

Which AI providers are supported?

Groq, Ollama, Google Gemini, Anthropic Claude, and OpenAI. You can enter any custom model name and switch providers at any time without re-analyzing.

How large a codebase can it handle?

MapMyCode processes files in batches and skips auto-generated code, so it scales well. Most codebases of 50–500 source files complete in under two minutes.

Which programming languages are supported?

20+ languages: TypeScript, JavaScript, Python, Go, Rust, Java, Kotlin, C, C++, C#, Ruby, PHP, Swift, Vue, Svelte, Astro, GraphQL, Prisma, SQL, Shell, and more.
