DataCert

Certify your data quality instantly. No cloud. No upload. 100% Local.

DataCert is a high-performance, browser-based profiling suite designed for data engineers who value privacy and speed. By leveraging Rust compiled to WebAssembly, DataCert processes millions of rows directly on your device - your data never leaves your machine.

⚡ Quick Start

Jump in immediately from your terminal:

npx datacert

🚀 Why DataCert?

🎯 The Mission

Our goal is to make data profiling as ubiquitous as ls or grep. DataCert was built to be the "Data Quality Swiss Army Knife"—a tool that is always ready, requires zero setup, and treats your data with the privacy it deserves.

• Private by Design: We don't want your data. In an era of data leaks, DataCert ensures your PII and sensitive internal data never leave your browser's memory.
• Instant Gratification: From raw file to comprehensive profile in seconds. No login, no cloud configuration, no waiting.
• Collaborative Audits: High-fidelity reporting allows teams to share quality insights without ever needing to move the underlying datasets.

🛠️ Getting Started

CLI & Local UI (Recommended)

The fastest way to use DataCert is via npx. This launches the profiler directly in your browser using your local machine for analysis:

npx datacert

Automated Profiling (CI/CD)

Run headless profiling with pass/fail quality gates for your data pipelines:

npx datacert profile data.csv --fail-on-missing 5

See the CLI Guide for more.
