CSFree is a desktop application built with web technologies for the user interface and Rust to handle core memory data. It opens CSV files directly — no browser, no cloud, no nonsense. Features include in-grid editing, search with match navigation, and a status bar showing row and column counts.

Note: CSFree is under active development and not yet production-ready. Memory efficiency is still being optimized — large files may cause higher-than-expected RAM usage. Use with that in mind.
