How to Keep Slack Active: 5 Methods Compared

To keep Slack active, you must keep supplying activity from a Slack client or use a service that manages presence for you. Slack normally marks you away after 10 minutes of desktop inactivity. The main options are returning to Slack manually, keeping the mobile app foregrounded, using a mouse jiggler, running browser automation, or using scheduled presence.

The right method depends on whether you need one device or several workspaces covered, whether company policy permits automation, and whether your status should stay green all day or only during real working hours. This guide compares the trade-offs, including a scheduled way to keep Slack active, so you can choose deliberately.

Why Does Slack Show You as "Away"?

Slack’s official documentation says you are set to away after 10 minutes of desktop inactivity, or when you navigate away from or close the mobile app. Slack is measuring activity, not productivity, which is why Slack away status can be inaccurate during reading, calls, or focused work.

This means even if you're actively reading a document, on a phone call, or sketching on paper, Slack assumes you've left. And your team sees that little gray circle next to your name.

Method 1: Mouse Jigglers (Hardware)

A mouse jiggler is a small USB device that simulates mouse movement. Plug it in and your computer thinks you're moving the mouse, preventing both your screensaver and Slack's inactivity timer from triggering. They cost $10–$25 and require no software installation.

Downsides: It's a physical device you need to carry. Some corporate IT departments detect and flag USB HID devices they don't recognize. And it only works on the machine it's plugged into — if you have Slack on multiple devices, the others will still show you as away.

Method 2: Mouse Jiggler Software

Software mouse jigglers (like Caffeine on Mac or Mouse Jiggler on Windows) move your cursor a pixel or two at set intervals. They achieve the same effect as hardware jigglers without the USB device.

Downsides: Some require admin privileges to install. They keep your entire computer "awake," which can interfere with other things like screensavers and power management. And again, they only work on one machine at a time.

Keep Slack active during your working hours

NotAway keeps your Slack presence active on a schedule, so your status reflects when you're actually available.

Method 3: Scripts and Browser Extensions

Developers sometimes use scripts or extensions that automate activity inside Slack’s web client. These can work, but they are fragile: browser behavior changes, Slack can change its interface, and authentication sessions can expire.

Downsides: High maintenance. You need to update tokens when they expire, fix scripts when Slack updates their API, and manage one script per workspace if you're in multiple Slack teams.

Method 4: The Phone Trick

Keep the Slack mobile app open and in the foreground on your phone. Slack considers mobile activity valid, so as long as the app is visible, you'll appear active. Some people leave their phone propped up with Slack open while they work on their computer.

Downsides: Drains your phone battery. You can't use your phone for anything else. Push notifications may still mark you as idle if you switch apps. It also only covers one workspace.

Method 5: Use NotAway (Automated Solution)

NotAway is a service built specifically to solve this problem. You connect your Slack workspaces, set a schedule (e.g., Monday–Friday, 9 AM–6 PM), and NotAway automatically keeps your status active during those hours. It works in the background — no hardware, no scripts, no phone tricks.

Unlike the other methods, NotAway supports multiple workspaces at once, runs on a schedule so it's not active 24/7, and doesn't require any software on your computer.

If your main goal is the Slack green dot, schedule-based presence is usually more accurate than keeping a device awake all day.

Comparison

Hardware jiggler	No	No	Low
Software jiggler	No	No	Low
Scripts/Extensions	Partial	Manual	High
Phone trick	No	No	Medium
NotAway	Yes	Yes	Low

Which Method Should You Choose?

Occasional inactivity: Return to Slack manually or set a custom status explaining when you will respond.
One unmanaged computer: A software utility may be enough, provided it is permitted by your employer.
A locked-down work device: Do not install hardware or software without checking company policy.
Multiple workspaces or fixed hours: Scheduled presence avoids keeping a particular computer or phone running.

Frequently Asked Questions

Does manually setting Slack to active keep it active?

It changes your current availability, but it does not disable Slack’s automatic activity detection. Slack can mark you away again after inactivity.

Does leaving Slack open keep the green dot on?

Not indefinitely. On desktop, an open Slack client can still show you as away after 10 minutes of desktop inactivity.

What is the best way to keep Slack active?

For one-off gaps, manual activity is simplest. For consistent working hours or several workspaces, scheduled presence is more reliable because it does not depend on one device staying awake.
