DataCertCertify 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.
Jump in immediately from your terminal:
npx datacert
| 🛡️ Privacy First | 🏎️ Near-Native Speed | 🛠️ Zero dependencies |
|---|---|---|
| Processing happens entirely in your browser's memory. Safe for PII and sensitive internal data. | Rust/WASM streaming engine handles massive CSVs faster than Python-based alternatives. | No Python setup, no Docker, no Cloud console. Just drop your file and go. |
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.
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
Run headless profiling with pass/fail quality gates for your data pipelines:
npx datacert profile data.csv --fail-on-missing 5
