A modern cross-platform process manager with real-time monitoring, performance profiles, power control, and a full audio mixer. The Task Manager, Activity Monitor, and System Monitor alternative — built in Rust.
A live view of your whole machine: CPU cores, memory, GPU, disk, network and power. Sort by what's hurting you, then act on it in one click.
Save priority and CPU-affinity rules per app, match them with regex, and let Better Task Manager keep applying them in the background — no manual babysitting every time an app restarts.
Direct SMC and Metal access for battery longevity, display brightness and cooling — features you'd normally need three separate apps for.
Cap the charge to protect long-term battery health, force a controlled discharge, and keep an eye on cycle count and charge history — straight from the SMC.
Push XDR displays past their normal ceiling with adaptive colour correction, rendered on Metal.
Take manual control of fan speed to trade silence for cooling — or run cool under sustained load when it matters.
Independent volume, EQ and routing for every running app. Send a game to your speakers and a call to your headset, or pipe anything into a DAW or OBS — without touching System Settings.
Rule-based cleanup by age, extension and size — scheduled hourly to monthly. Files go to the Trash, never a hard delete.
Per-volume overview and a drill-down treemap explorer — find the biggest offenders on any disk in seconds. A cross-platform WizTree alternative.
Survives the roughest performance hiccups — unlike the native Windows Task Manager, macOS Activity Monitor and Linux System Monitor.
Handles heavy system load and memory pressure without freezing
Instantly responsive UI even when your system is struggling to breathe
Minimal resource usage — runs efficiently without draining your system
Memory-safe by design, with no undefined behaviour or memory leaks
Free forever for the essentials. Upgrade for the power features.
Everything you need to get started.
Unlock the full power of your machine.
No credit card required
The task manager, activity monitor and system monitor alternative — answered.
Better Task Manager is a modern, free alternative to the native Windows Task Manager. It shows real-time per-process CPU, memory, GPU, disk and network usage, lets you kill, suspend and re-prioritise processes, assign CPU affinity, and save performance profiles that re-apply themselves automatically. It's built in Rust and stays responsive under heavy system load, where the native Task Manager often freezes.
Yes. Better Task Manager is a cross-platform alternative to macOS Activity Monitor with a live view of every process — CPU, memory, GPU, disk, network and energy impact — plus macOS-only hardware control that Activity Monitor lacks: battery charge limiting, XDR display brightness boost, and manual fan control. It replaces Activity Monitor, AlDente and BetterDisplay in a single app.
Better Task Manager is a cross-platform process manager that runs on Linux as well as macOS and Windows. It provides real-time system monitoring, a process hierarchy view, a ports explorer, and performance profiles with regex matching — a modern alternative to the default GNOME/KDE System Monitor.
Yes. The core process manager — the process list, CPU/RAM/disk usage, killing and suspending processes, performance graphs, the audio mixer and performance profiles — is free forever with no account required. A Pro license (£5 per device per year, with a 7-day free trial) unlocks battery charge limiting and discharge control on macOS.
Better Task Manager runs on macOS, Windows and Linux — a single cross-platform app rather than three separate tools.
On macOS, yes. Better Task Manager talks directly to the SMC and Metal to cap battery charge and force a controlled discharge for long-term battery health (an AlDente alternative), take manual control of fan speed, and push XDR displays past their normal brightness ceiling with adaptive colour correction (a BetterDisplay alternative) — features the operating system normally keeps to itself.
Yes. Better Task Manager includes a full per-app audio mixer with independent volume, multi-band parametric EQ and virtual routing — send a game to your speakers and a call to your headset, or pipe any app into a DAW or OBS, without touching System Settings.
Yes. Better Task Manager includes a storage tree — a disk space analyzer with a per-volume overview and a drill-down treemap explorer that finds the biggest folders and files on any disk in seconds. Unlike WizTree, which is Windows-only, it runs on macOS, Windows and Linux, and pairs with rule-based folder cleanup to actually reclaim the space. It's a cross-platform alternative to WizTree, WinDirStat and DaisyDisk.
It's built in Rust, which is memory-safe by design with no undefined behaviour or memory leaks. It uses minimal system resources and stays instantly responsive even under extreme load and memory pressure.
Available for macOS, Windows, and Linux.
