# Vitals vs ProcessSpy Canonical page: https://vitalsmac.com/vs/processspy By Atta Ur Rehman Shah, maker of Vitals. ProcessSpy checked on its maker's site September 27, 2026. **Short answer:** ProcessSpy and Vitals both make sense of helper processes, then part ways. ProcessSpy is a process explorer for developers: the command line, environment and signature of every process, regex and JavaScript filters, and a record of processes after they finish. Vitals is for the everyday question: one row per app, always, with 30 days of history and alerts included. Choose ProcessSpy to read a process; choose Vitals to know which app is using your Mac. | | Vitals | ProcessSpy | |---|---|---| | What it is | An Activity Monitor replacement with a menu bar item | A process explorer, in the mould of Windows Process Explorer | | List of what is running | Every app, with its helper processes counted in | Every process, as a list or a tree | | Helper processes counted under their app | Yes, always: one row per app | Yes, in its tree view, with rolled-up CPU, memory and threads | | History | 30 days for every metric, per app, included | Per-process CPU, memory and threads, in the paid version; length not stated | | Finished processes | Kept in the 30-day history | Remembered, with their command line and environment (paid) | | Alerts | When an app keeps the CPU busy, keeps growing in memory, or hammers the disk or network | Shortcuts can run on process events (paid) | | Process details | Path, and the ports it holds | Command line, path, version, environment, signature, QoS, native or Rosetta | | Search | By name | Regular expressions and JavaScript filters | | Menu bar | An icon, a figure or a graph, and a compact view of every metric | A dashboard with the same filters (paid) | | Temperatures and fans | CPU and GPU temperature, fan speed | No | | Dev servers and open ports | Grouped by project, idle ones pointed out | Not stated | | Price | $5 during the launch, $29 after, once | Free version; $34.99 once, unlimited Macs; also on Setapp | | Trial | None, a 14-day refund | A free version | | Requirements | macOS 15 or later | macOS 14 or later | ## Choose Vitals if - You want one row and one figure per app, without opening a tree - You want 30 days of history included, not as a paid extra - You want alerts, temperatures and a menu bar view of every metric - You want to know which project is holding a port Vitals website: [vitalsmac.com](https://vitalsmac.com/) ## Choose ProcessSpy if - You want Windows Process Explorer on a Mac - You need the command line, environment or signature of a process - You want to filter processes with regular expressions or JavaScript - You want to see a process after it has finished - You run it on many Macs: one license covers them all ProcessSpy website: https://process-spy.app/ ## Where Vitals pulls ahead **One row per app, without a tree.** ProcessSpy's tree view rolls helpers up under their parent, with totals for CPU, memory and threads. Vitals starts there: one row per app, always, with one figure for memory, CPU, energy, disk and network, and the processes underneath when you open it. **History included.** ProcessSpy keeps CPU, memory and thread history in its paid version, for a length its site does not state. Vitals keeps 30 days for every app and every metric, included in the price. **The whole Mac.** ProcessSpy has no temperatures or fans, and its menu bar dashboard is a paid feature. Vitals has temperatures, fan speed, battery and a menu bar view of every metric, included. ## Everything Vitals does - **Processes grouped by app.** Every helper process is added to the app that launched it, so a working Mac shows about 60 apps instead of about 1,000 processes, each with one figure for memory, CPU, energy, disk and network. - **A tab per subsystem.** Overview, CPU, Memory, Disk, Network, GPU and Battery, each with its live graph and the apps behind the figure. - **30 days of history.** Usage for the last 12 hours, 24 hours, 7 days and 30 days, with the apps that used the most. - **Alerts for misbehaving apps.** A notification when an app keeps the CPU busy, keeps growing in memory, or hammers the disk or network. - **Dev servers and open ports, by project.** Processes grouped by the project folder they run in, with their listening ports, and dev servers left idle for days pointed out and offered to stop. - **Menu bar monitor.** An icon, a figure, a small graph or several figures stacked, for CPU, memory, GPU, network, temperature or battery, with a compact view of every metric behind it. - **Temperatures, fans and batteries.** CPU and GPU temperature, fan speed, and the battery level of AirPods, mice and keyboards. - **Volume per app.** A volume mixer with a slider for each app playing sound. - **Quit and force quit.** Quit an app or a single process, always after a confirmation. - **Export as an image.** Save or copy a snapshot of the Mac as a 1200 × 630 share card or a dashboard image. ## Common questions **Can I use Vitals and ProcessSpy together?** Yes, and they suit each other: Vitals to find which app is responsible, ProcessSpy to read that process's command line, environment and signature. **Can Vitals filter with regular expressions or JavaScript?** No. Vitals filters apps and processes by name. ProcessSpy's filters are its strength. **Does Vitals remember finished processes?** It keeps every app's usage in its 30-day history, so an app that quit an hour ago still shows what it used. It does not keep a process's command line or environment after it exits. ## How we compared The ProcessSpy column comes from its maker's own site on September 27, 2026.
