## Background
Nexis began as a fork of [Stacer](https://github.com/oguzhaninan/Stacer), a popular Linux system optimizer created by oguzhaninan. After the original project went inactive in 2020, development continued here -- porting to Qt 6 and C++17, adding native macOS support, GPU monitoring, a hardware info panel, kiosk mode, and fixing hundreds of bugs and regressions inherited from the upstream codebase. As the feature-set diverged, the project was rebranded as Nexis to reflect that it had become something new. Stacer laid the foundation; Nexis is where it goes from here.
## Downloads
Install via [PPA](#install-via-ppa-ubuntu), [AUR](#install-via-aur-arch-linux), or [Homebrew](#install-via-homebrew-macos) for automatic updates, or download pre-built binaries from the [Releases page](https://github.com/s4solutionsllc/Nexis/releases/latest):
- **Linux x86_64**: `.deb` package, `.AppImage` portable, standalone binary
- **Linux ARM64** (aarch64): `.deb` package, `.AppImage` portable, standalone binary
- **macOS Apple Silicon**: `.dmg` disk image
### Install via PPA (Ubuntu)
```bash
sudo add-apt-repository ppa:s4solutionsllc/nexis
sudo apt update
sudo apt install nexis
```
Supports Ubuntu 22.04 (Jammy), 24.04 (Noble), and 25.04 (Plucky) on both x86_64 and ARM64. Updates are delivered automatically via `apt upgrade`.
### Install via AUR (Arch Linux)
```bash
yay -S nexis
```
Also works with `paru` or any other AUR helper. Builds from source — requires Qt6 development packages which are pulled in automatically. Updates are delivered via `yay -Syu`.
### Install via Homebrew (macOS)
```bash
brew tap s4solutionsllc/nexis
brew install --cask nexis
```
Requires macOS 12+ (Monterey) on Apple Silicon. Updates are delivered via `brew upgrade --cask nexis`.

## Building from Source
### Prerequisites
#### Linux
Install Qt 6 development libraries:
**Ubuntu / Debian:**
```bash
sudo apt install cmake g++ qt6-base-dev qt6-charts-dev qt6-svg-dev \
qt6-tools-dev-tools qt6-l10n-tools
```
**Fedora / RHEL:**
```bash
sudo dnf install cmake gcc-c++ qt6-qtbase-devel qt6-qtcharts-devel \
qt6-qtsvg-devel qt6-linguist
```
**Arch Linux:**
```bash
sudo pacman -S cmake qt6-base qt6-charts qt6-svg qt6-tools
```
> **Note:** On minimal or headless environments you may also need `libgl1-mesa-dev` (Debian/Ubuntu) or equivalent OpenGL headers.
#### macOS
```bash
brew install qt@6 cmake adwaita-icon-theme
```
After installing, ensure Qt is in your path:
```bash
export PATH="$(brew --prefix qt@6)/bin:$PATH"
```
### Build
```bash
mkdir -p build && cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix qt@6)
make -j$(sysctl -n hw.ncpu)
```
## Development
Nexis is co-authored by [Claude Code](https://claude.ai/claude-code), Anthropic's AI coding agent. Claude Code contributes to architecture decisions, feature implementation, bug fixes, CI/CD pipelines, and release engineering -- working alongside the human maintainer as a pair-programming partner.
## Translations
Nexis supports 34 languages. Translations are managed via [Crowdin](https://crowdin.com/project/nexis) -- no coding required to contribute. Sign up, pick a language, and start translating in your browser.
New translations are automatically synced back to this repository via pull request.
### Maintainer Setup
To enable the Crowdin sync pipeline for a new fork:
1. Create a project at [crowdin.com](https://crowdin.com) (free for open source).
2. Add two repository secrets in GitHub Settings > Secrets:
- `CROWDIN_PROJECT_ID` -- numeric project ID from the Crowdin dashboard.
- `CROWDIN_PERSONAL_TOKEN` -- personal access token from Crowdin account settings.
3. Seed the project with existing translations (one-time):
```bash
brew install crowdin # macOS
export CROWDIN_PROJECT_ID=
export CROWDIN_PERSONAL_TOKEN=
crowdin upload sources --config crowdin.yml
crowdin upload translations --config crowdin.yml --auto-approve-imported
```
4. The `crowdin-sync.yml` GitHub Action handles ongoing sync automatically.
## Contributing
Bug reports and feature requests are welcome! Please [open an issue](https://github.com/s4solutionsllc/Nexis/issues) or submit a pull request. See [CHANGELOG.md](CHANGELOG.md) for release history.
## Maintenance & Releases
Nexis is a free, GPL-3.0 reference product with a single named maintainer and a strict capacity time-box. If you are a future maintainer (human or agent) inheriting the project, read these in order:
- [`docs/MAINTAINER_SOP.md`](docs/MAINTAINER_SOP.md) — ownership, time-box, on-call cadence, decision rights.
- [`RELEASE.md`](RELEASE.md) — end-to-end release runbook (tag, build matrix, code signing, Homebrew/AUR/PPA bumps, CVE expedited path, post-release verification, dry-run procedure).
