A self-contained, single-binary system monitor for Windows — inspired by htop. CPU, memory, GPU, network, and processes. Live. In your terminal.
winget install michaelsanford.wtop
Six panels, one binary. Live metrics updated every second across every subsystem that matters.
Per-core utilisation bars in a compact grid. Colour-coded green → yellow → red as load climbs. Aggregate total always pinned at the bottom.
RAM and swap in GiB with htop-style colour layering — used, cached, and buffered pages each in a distinct colour so you know exactly where memory is going.
Automatic detection: full telemetry (util, VRAM, temp, power, clocks, fan, P-state) from NVIDIA via nvidia-smi, or utilisation from AMD/Intel via Get-Counter. Loads in the background — other panels appear immediately while the GPU panel populates.
Per-interface send/receive rates in real time. Loopback and zero-traffic interfaces hidden automatically. Delta-per-second calculation handles clock resets cleanly.
Top processes sortable by CPU%, memory, PID, or name. Toggle an htop-style tree view (t) to see parent → child relationships with box-drawing connectors. Kill any selected process with a confirmation step.
Single statically-linked binary with no installer, no runtime, and no admin rights to run. CGO-free. Just download wtop.exe and go.
Every action is one keypress away. No mouse. No menus.
| Key | Action |
|---|---|
| ↑ / ↓ or k / j | Scroll process list |
| s | Cycle sort column — CPU% → Mem MB → PID → Name |
| d | Reverse sort order |
| t | Toggle tree view — htop-style parent → child with box-drawing connectors; tree● indicator appears in the status bar when active |
| g | Cycle between GPUs (when multiple are detected) |
| x | Kill selected process — asks for confirmation |
| y / n / Esc | Confirm or cancel kill |
| q / Ctrl+C | Quit |
Install with winget, or download a pre-built binary for amd64 and arm64. No installer. No admin rights.
winget install michaelsanford.wtop
Or download the latest release and run directly:
# No installer needed
.\wtop-v1.0.0-windows-amd64.exe
Build from source (Go 1.26+ required):
git clone https://github.com/michaelsanford/wtop cd wtop go build -o wtop.exe ./cmd/wtop/ .\wtop.exe
Every release is built reproducibly in GitHub Actions and ships with a complete audit trail.
Full dependency inventory in JSON format — wtop-vX.Y.Z-sbom.cdx.json — attached to every release.
Keyless signature via Sigstore. A .bundle file ships with each binary for offline verification.
GitHub Actions attestation links each binary to its exact source commit and workflow run. Verify with gh attestation verify.
