Instead of bottom (btm)

bottom (btm) alternatives

bottom (btm) gives Linux, macOS, and Windows users a free terminal monitor with customizable views of system activity. It graphs CPU, memory, swap, network, and disk use over time, while widgets cover processes, storage, temperatures, and battery use. Process search, sorting, tree mode, kill signals, zoomable intervals, themes, layouts, filtering, and a read-only option support detailed local oversight. Basic and focus modes provide either a compact process view or an enlarged widget.

An alternative may fit better when you need browser or remote access, APIs, container monitoring, service supervision, automated recovery, event-level tracing, or Windows-specific process optimization. bottom (btm) is centered on local terminal monitoring, and Android support is unofficial with limited testing and support. Before switching, compare platform coverage, access methods, exports, alerts, persistent rules, process automation, and whether a free plan meets your needs or a paid tier is acceptable.
