Use cases

IdeUltra isn't trying to replace your full-fat IDE. It's the tool you reach for when starting one feels heavy.

Quick edits without booting VS Code

Fix a typo in nginx.conf, tweak ~/.zshrc, change one line of a config deep in a project. IdeUltra opens in under 150 ms, the file lands in the editor in under 50 ms, you're typing immediately. Save, quit, gone.

Reviewing a downloaded repository

Just cloned a repo to look at a specific function? IdeUltra gives you syntax-highlighted browsing right away — no language servers, no "What would you like to do?" modals, no extension recommendations bar. Press ⌘P, type a few characters of the file you want, jump to it.

Pairing with coding agents

When an agent edits files in your workspace, the file watcher picks up the change. Clean buffers reload silently; dirty buffers show a "View diff" banner so you can see what changed before deciding. You'll never lose in-progress work to an agent's overwrite.

SSH sessions and battery-conscious laptops

A 7.6 MB native binary that idles at near-zero CPU is gentle on battery and snappy over an X-forward. No web stack, no GPU shaders running unprompted, no fans spinning up because of an Electron renderer process.

Plain-text tasks: notes, drafts, dotfiles

Open a folder full of markdown, edit, save. ⌥⌘M gives you a live preview side-pane. The status bar shows word count and an estimated reading time for any prose file.

Project-wide find & replace

⇧⌘F searches every file in the workspace, grouped by file. Toggle Replace and IdeUltra rewrites every match after a confirmation step. Open tabs update in place — your unsaved edits aren't clobbered.

Comparing files side-by-side

⌘\ opens a second pane. Two files, two carets, one window. Click either pane to focus it; the focused pane drives the find bar and command palette.
