Hi all I m the creator of VisiLens.

Quick intro: VisiLens opens 1M+ rows locally in ~1.7s. It runs on FastAPI + React and never uploads your data.

This forum is where I ll collect feedback, bugs, and feature ideas. I ll be active here and reply fast.

VisiLens - Open 1M+ rows in <2s. Local-first CSV & Parquet explorer.

VisiLens solves the dilemma between slow Excel and complex Pandas code. It is a local-first, zero-config data explorer. What's different: Speed & Scale: Opens 1M+ rows in ~1.7s by streaming data from the VisiData engine. Privacy: Runs 100% locally via FastAPI/React. Your data never leaves your machine. Usability: Provides a modern, mouse-friendly web GUI (sorting, filtering) for quick exploration without needing to memorize CLI shortcuts.
