A Rust library (crate) for reading and easily navigating forward, backward or randomly through the lines of huge files. Tested with files of over 300 GB.

An experimental text editor written in Rust with very large file support

86,420,337 lines — a 10 GB log — open in 80 ms, and 0 bytes of it live in memory. A Mac-native viewer and editor for the files that break everything else: edit in place, save with atomic writes, diff and merge side by side.

An memory efficient, fast excel file reader designed for processing large Xlsx files.

This library allows you to handle gigabyte order huge files easily with high performance. You can search bytes or words / read data/text from huge files.

Fast multi-threaded data generator.

Easily create random file useful for software testing, network speed testing and other types of testing that requires large files

A fast, native Windows code editor with syntax highlighting, intelligent code reformatting, and a built-in hex editor.

Library to help with memory allocations backed by files

Gigantic text & log viewer — view and search 890M-line / 51GB files from the moment you open them (indexing runs in the background). .NET 10 / Avalonia, macOS / Windows / Linux + WASM. 大容量テキスト/ログビューア
