A lightweight, modern editor focused on speed, readability, and automatic syntax highlighting.
Minimal by design: quick edits, fast file access, no IDE bloat.
Release Download: GitHub Releases
> Status: **beta**
> Latest release: **v0.4.4-beta**
> Platform target: **macOS 26 (Tahoe)**
> Apple Silicon: tested / Intel: not tested
## Download
Prebuilt binaries are available on [GitHub Releases](https://github.com/h3pdesign/Neon-Vision-Editor/releases).
- Latest release: **v0.4.4-beta**
- Architecture: Apple Silicon (Intel not tested)
- Notarization: *not yet*
## Getting Started (30 Seconds)
1. Install using `curl` or Homebrew (below), or download the latest `.zip`/`.dmg` from [Releases](https://github.com/h3pdesign/Neon-Vision-Editor/releases).
2. Move `Neon Vision Editor.app` to `/Applications`.
3. Launch the app.
4. Open a file with `Cmd+O`.
5. Use `Cmd+P` for Quick Open and `Cmd+F` for Find & Replace.
6. Toggle Vim mode with `Cmd+Shift+V` if needed.
## Install
### Quick install (curl)
Install the latest release directly:
```bash
curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh
```
Install without admin password prompts (user-local app folder):
```bash
curl -fsSL https://raw.githubusercontent.com/h3pdesign/Neon-Vision-Editor/main/scripts/install.sh | sh -s -- --appdir "$HOME/Applications"
```
### Homebrew
```bash
brew tap h3pdesign/tap
brew install --cask neon-vision-editor
```
Tap repository: [h3pdesign/homebrew-tap](https://github.com/h3pdesign/homebrew-tap)
If Homebrew asks for an admin password, it is usually because casks install into `/Applications`.
Use this to avoid that:
```bash
brew install --cask --appdir="$HOME/Applications" neon-vision-editor
```
### Gatekeeper (macOS 26 Tahoe)
If macOS blocks first launch:
1. Open **System Settings**.
2. Go to **Privacy & Security**.
3. In **Security**, find the blocked app message.
4. Click **Open Anyway**.
5. Confirm the dialog.
