Single-host system diagnostics TUI.

System diagnostics in your terminal.
Live system activity in syswatch --dense.
Monitor CPU, memory, disks, processes, GPU, power and network activity on macOS and Linux. Scrub recent history, record sessions, and investigate spikes with heuristic anomaly cards. SysWatch is read-only and runs without sudo; available measurements depend on your platform and permissions.
brew install syswatch # macOS / Linux
nix-shell -p syswatch # NixOS / Nix
paru -S syswatch # Arch (AUR)
cargo install syswatch # build from source with Rust
Prebuilt binaries are available for macOS and Linux (x86_64 and aarch64), with static Linux builds and an armv5te build for older NAS hardware. Build from source.
syswatch # twelve tabs, default 1 Hz refresh
syswatch --lite # one 80×24 screen
syswatch --dense # all main subsystems, designed for 130×44
syswatch --tab procs # start on Processes
1–9, 0, - and + switch tabs. V cycles views, ? shows help, q quits.
Use ← / → to scrub recent history and End to return live.

Lite (--lite) | 80×24 | SSH sessions and small terminals |
Dense (--dense) | Designed for 130×44 | CPU, memory, network, cores, disk and processes together |
In Dense, 1–6 zoom a panel and Esc restores the grid.

Press R to record an interactive session or S to save a snapshot.
syswatch --record --keep 24h # foreground recording without a TUI
syswatch --replay session.swr # replay a recording
syswatch snapshot --json # one live sample
syswatch why # sample for 30s, explain detected anomalies
syswatch diff before.swr after.swr # compare recordings
Live scrubbing holds 120 samples (two minutes at the default refresh rate).
Record longer sessions to disk. Headless recording rotates files and prunes old
chunks according to --keep; it runs until stopped.

NetWatch covers network diagnostics; DiskWatch covers disk activity. They share the terminal layout and palette.
Community packagers maintain the Nix and Arch packages. Repology tracks package versions. File packaging issues with the packagers and SysWatch bugs here.
