BigEdit is a streaming TUI editor for very large files. Edit multi-gigabyte files without loading them into memory.
This is free and open source software.
Features include:
- Edit files larger than RAM – Only loads what’s visible on screen.
- Nano-like keybindings – Familiar interface for terminal users.
- Vi mode – Toggle with F2 for vi-style editing (h/j/k/l, i/a/o, :w/:q).
- Undo/Redo – Full undo support (Ctrl+Z/Ctrl+Y in Nano, u/Ctrl+R in Vi).
- FUSE virtual filesystem – Other programs can see your changes before you compact.
- Journal-based saves – Instant writes without rewriting the entire file.
- Systemd service – Auto-mount patched file views on boot.
