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.

How to keep Slack active all the time

There is no permanent always-active switch in Slack. Manually setting yourself active changes the current indicator, not the automatic inactivity behavior. For occasional gaps, return to Slack or explain your availability with a custom status. For regular work hours, NotAway manages presence on a schedule without keeping a particular device awake. Use automation only if your workplace permits it, and set hours when you can actually respond.

Desktop or phone: which method fits?

A mouse jiggler depends on an awake computer. Sleep-prevention tools do not necessarily simulate input. On a phone, Slack considers you active while the app is open; switching away or closing it can make you away. Choose based on the device you can keep running, not just whether an app is installed.

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 hardware mouse jiggler simulates mouse movement on an awake computer. That input may prevent desktop inactivity, but it is not a Slack setting or a guarantee across every device and client.

Downsides: It depends on the connected computer staying awake, and your workplace may prohibit it. Activity can affect workspaces connected on that computer, but a jiggler cannot independently manage each workspace’s connection or working hours.

Method 2: Mouse Jiggler Software

Input-simulation tools such as Mouse Jiggler on Windows generate mouse activity without a USB device. Do not confuse them with Mac Caffeine, Amphetamine or caffeinate: preventing sleep alone does not necessarily generate the input that keeps Slack active.

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: It consumes battery and prevents normal use of other apps. Switching apps or closing Slack can make you away; receiving push notifications does not keep you active. Do not assume every connected workspace stays active just because one is open.

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.

NotAway manages up to seven workspace connections on your chosen schedule, without keeping a local utility running on your computer. Connection credentials can expire and need refreshing; check your workspace connection if presence stops updating.

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

Comparison

Method	Multi-Workspace	Schedule	Maintenance
Hardware jiggler	On the connected computer	No	Low
Software jiggler	On the connected computer	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.
