TheEasyApp

Overview

The spreadsheet that never slows down — explore and edit multi-million-row CSVs with sub-200ms response times.

TheEasyApp is a spreadsheet-style explorer for very large CSV files, running on Bun end-to-end. It streams data from local files or remote URLs through Web Workers to keep the UI responsive, renders 100k+ rows smoothly with a virtualized grid, and hydrates DuckDB server-side so filters, search, and aggregations run in milliseconds. Sort order, filters, and search live in the URL, so any session can be shared or reloaded. Self-hostable as a single Bun binary — your data never leaves your server.
