About Us - ipynbcompare | *.ipynb Notebook Comparison Tool

Our Mission

We're on a mission to make Jupyter Notebook comparison simple, fast, and secure for everyone.

ipynbcompare was created to solve a common problem faced by developers, researchers, and analysts: comparing different versions of Jupyter Notebooks (*.ipynb files) efficiently.

Traditional diff tools treat notebooks as plain text or JSON, making it nearly impossible to understand what actually changed. Our tool understands the notebook structure - cells, outputs, markdown - and presents differences in a way that makes sense.

Our Story

As developers and researchers ourselves, we've felt the frustration of trying to compare Jupyter Notebooks. Whether it's reviewing a colleague's changes, tracking experiment iterations, or understanding what changed between versions - the existing tools just weren't cutting it.

Difference checking tools shows incomprehensible JSON. Other tools require installation, configuration, or subscriptions. We wanted something that just works - instantly, securely, and without hassle.

So we built ipynbcompare. A tool that runs entirely in your browser, requires no sign-up, and keeps your data completely private. Whether you're using Jupyter, Google Colab, or Kaggle - comparing notebooks shouldn't be harder than writing them.

Our Values

The principles that guide everything we build

🔒

Privacy First

Your data stays on your device. We never see, store, or transmit your notebooks. Privacy isn't a feature - it's foundational to how we build.

⚡

Speed Matters

Every millisecond counts. We obsess over performance so you can focus on your work, not waiting for tools to load.

🎯

Simplicity

No installation, no configuration, no account required. Upload two *.ipynb files, click compare. That's it.

📱

Works Everywhere

Use on any device - desktop, laptop, tablet, iPhone, or Android. Our responsive design works beautifully everywhere.

100% Client-Side Processing All computation happens in your browser
