Everything you need to
read a codebase fast

No setup. No config. Drop in a ZIP and every layer of the project becomes immediately readable.

🔍

Tech Stack Detection

Automatically identifies frameworks, libraries, databases, and tooling from your package files and source code — including Node.js, Spring Boot, and Maven projects.

API Flow Visualization

Traces every Express.js route from HTTP request through middleware, handlers, and internal calls like DB queries and service functions — all the way to the response.

📦

Dependency Analysis

Scans and categorizes all dependencies across npm, Maven, and Gradle ecosystems. Understand exactly what your project relies on and why.

🗂️

File Browser

Navigate the full directory tree with syntax-highlighted file previews. Instantly understand project structure without cloning or setting up a local environment.

AI-Powered Insights

Powered by Groq and Llama 3.3 70B, the AI analysis layer adds confidence scores, architectural pattern recognition, and improvement recommendations.

📊

Statistics Dashboard

File counts by type, size breakdowns, largest files, directory depth — quantified project metrics that give you an immediate sense of scale and complexity.

Three steps to full
project clarity

Blueprints does the heavy lifting so you can focus on understanding, not setup.

01

Upload your project

Drag in a ZIP file or paste a GitHub repository URL. Blueprints extracts and indexes the entire codebase in the background.

02

Analysis runs instantly

All analyzers run in parallel — tech stack, dependencies, directory structure, and API flow detection complete in a few seconds and are cached to the database.

03

Explore and share

Browse every tab at your own pace. Optionally trigger AI analysis for deeper insights. Every subsequent page load is instant — results are persisted.

Works with your ecosystem

Deep support for the JavaScript and JVM worlds, with more ecosystems on the way.
