Nexis: The Free, Maintained
Stacer Alternative

If you've searched for a Stacer alternative, you've already noticed the problem: Stacer's development stopped in 2022. No updates, no security patches, no Qt 6, and no support for any Linux distribution released in the last two years.

Nexis is the maintained successor. It does everything Stacer did, runs on both Linux and macOS, and ships regular releases with active bug fixes and new features.

What Happened to Stacer?

Stacer was a popular open-source Linux system optimizer that accumulated over 16,000 GitHub stars. But after 2022, commits slowed and then stopped entirely. Issues pile up unanswered, and the last release doesn't install cleanly on Ubuntu 24.04, Fedora 40, or other current distributions. If you're running a modern system, Stacer simply doesn't work reliably anymore.

Why Choose Nexis as Your Stacer Alternative?

Nexis was built to fill exactly the gap Stacer left:

• Actively maintained — releases every 4–6 weeks, critical bugs fixed within days
• Qt 6 native — not Electron; lower memory, better HiDPI, faster startup
• Linux and macOS — one tool for mixed-platform teams or dual-boot setups
• GPU monitoring — NVIDIA and AMD GPU stats, something Stacer never supported
• GPL-3.0 licensed — free to use, modify, and redistribute, forever

Nexis vs Stacer: Feature Comparison

What Does Nexis Include?

Dashboard

Real-time CPU, memory, swap, disk I/O, GPU, and network charts — everything you need for at-a-glance system health.

System Cleaner

Scan for application caches, package manager leftovers, and log files taking up disk space.

Startup Manager

Enable or disable startup applications without touching a config file.

Services Manager

Start, stop, enable, and disable systemd services from a GUI.

Process Manager

Sort processes by CPU or memory; kill runaway processes in one click.

GPU Monitor

View NVIDIA and AMD GPU load, VRAM usage, and temperature in real time. Stacer never supported this.

Does Nexis Work on macOS?

Yes. Nexis runs natively on macOS (Apple Silicon and Intel). It provides CPU, memory, disk, and GPU monitoring, plus a system cleaner for application caches. Stacer was Linux-only; Nexis works on both, making it the only free, open-source Stacer-class optimizer that covers mixed-platform teams.

Is Nexis Free?

Yes. Nexis is GPL-3.0 licensed and will remain free forever. There is no paid tier, no premium features, and no subscription. It is maintained by open-source contributors — not by selling access.
