The code has the truth. You don't have the picture.

One command reads your codebase and maps every API connection into an interactive canvas. Zero manual setup.

The Problem

We spend days tracing requests across services just to understand how a single feature works.

01

Blind Debugging

Debugging across Service A → B → C without a map.

02

Stale Documentation

Postman collections are out of sync the day they're written.

03

Wasted Time

3 days just to understand one API chain.

How It Works

From codebase to canvas in seconds.

trace-mapper — bash
01

Run the CLI

Navigate to your project root and run a single command. Trace maps your codebase entirely locally on your machine—no code ever leaves your laptop.

02

AST Parsing

Trace analyzes your Abstract Syntax Tree to identify frontend API calls, backend endpoints, and external services, automatically resolving the exact data routes.

fetch('/api/users')
app/api/users/route.ts
Home Page
GET /api/users
POST /api/upload
03

Visual Flow

Instantly view a beautiful, interactive node graph mapping exactly how your front-end components communicate with your backend APIs.

Live Canvas
