Amphetamine keeps your Mac awake, which stops the instant away flip that sleep causes. It creates no keyboard or mouse input, so the 10-minute idle timer still turns you gray. What it fixes, what it cannot, and what to pair it with.

No. Slack's presence API gives a coworker only active or away, with no device. The phone shows up in one place, your account's access log, which paid-plan admins can export.

No. Slack shows coworkers a present-tense dot and never a last-seen time. On paid plans, admins get a Last active date per member. Who sees what, and how to find someone's last message.

No. The Slack desktop app reads one number, how long the computer has been idle, plus each device's connection state. It does not record your mouse path, your screen or your keystrokes. The check, printed from the app's code.

Slack in a browser tab follows the same 10-minute timer as the desktop app, with two extra ways to die: tab discarding and the browser closing. What counts as input in a tab, the Memory Saver and sleeping-tabs exceptions, and when the tab beats the app.

A mouse jiggler keeps the Slack desktop app active while the computer is awake and unlocked, and stops with the lid. A server-side tool does not need the computer. What each costs and where each fails.

On Linux the away flip comes from two places: Slack's 10-minute idle timer and your desktop's idle-blank-suspend chain. The GNOME and KDE settings that stop sleep-away, what systemd-inhibit and Caffeine cannot do, and the xdotool route with its Wayland limit.

Presence Scheduler pings the Slack API to stop away flips and adds a Chrome extension on your machine for the green dot. Slack Green holds the whole session from a cloud server. The mechanism difference decides which fits you.

Slack Green and StayGreenOnSlack are the two closest products in the server-side presence category: both keep your Slack status active from the cloud on a schedule. The real differences are setup, the self-hosted option, languages, the API, and price.

Slack feels trigger-happy because the timer is shorter than people expect, 10 minutes without keyboard or mouse input, and three common events skip it entirely. Each trigger has a tell and a fix.

Slack decides you are away from four signals: keyboard or mouse input on your computer, its sleep and lock state, whether the phone app is on screen, and the manual away setting. The desktop app reads the computer's idle time every 10 seconds.

Slack on Android reports you active only while the app is visible with the screen on. The settings that hold that state: screen timeout, the developer-options Stay awake switch, split screen, and why exempting Slack from battery optimization does not touch the green dot.

Windows flips you to away three ways: Slack's 10-minute idle timer, screen sleep and lock, and on work laptops an IT lock policy you cannot change. What each fix covers, what Caffeine and PowerToys Awake miss, and what works with the lid closed.

A Mac flips you to away two ways: Slack's 10-minute idle timer and macOS sleep, which cuts the dot in seconds. The settings that stop sleep-away, what caffeinate and Amphetamine miss, and what keeps the dot green with the lid closed.

How Slack decides the green dot, with a test in the Slack web app on 30 September 2026: the four dot states, why posting does not undo a manual Away, and why status text never moves the dot.
