Idle Pilot vs Hammerspoon

Compare Idle Pilot to Hammerspoon for Slack presence on Mac. Cloud-based scheduling vs Lua scripting automation for keeping your Slack status active.

Quick Verdict

Idle Pilot is the practical choice for Slack presence. Hammerspoon is a great tool for Mac automation enthusiasts, but it's overengineered for this specific problem.

Hammerspoon can simulate keystrokes or mouse movement in the Slack window to prevent idle detection, but your Mac has to stay awake and Slack has to stay open. The scripting is straightforward for developers familiar with Lua, but it's still a local solution with the same limitations as any other local tool. Idle Pilot sidesteps the entire approach by managing presence server-side.

Feature Comparison

Feature	Idle Pilot	Hammerspoon
Works with Mac asleep	Yes	No
Programming required	No	Yes (Lua)
Platform support	Any (cloud-based)	Mac only
Scheduling	Built-in UI	Custom Lua code
Other automation uses	Slack only	Extensive (windows, hotkeys, etc.)
Cost	$4/month	Free

Frequently Asked Questions

How would a Hammerspoon script keep Slack active?

A typical approach uses hs.timer to run a function every few minutes that either simulates a keystroke in the Slack window (via hs.eventtap) or uses hs.application to briefly focus Slack. Some scripts move the mouse to the Slack window coordinates. All of these require Slack to be running and your Mac to be awake.

Is Hammerspoon hard to set up for Slack presence?

If you're comfortable with basic programming, no. The Lua script is usually under 20 lines. The harder part is handling edge cases: what happens when Slack is minimized, when you have multiple desktops, or when macOS accessibility permissions change after an update. These are the kinds of ongoing maintenance issues that make cloud-based solutions appealing.

Does Hammerspoon work on Apple Silicon Macs?

Yes. Hammerspoon has native Apple Silicon support and runs well on M1/M2/M3/M4 Macs. Unlike kernel extension tools like NoSleep, Hammerspoon uses userspace APIs and doesn't have compatibility issues with modern macOS. The limitation for Slack presence is the same as any local tool — it can't work when your Mac sleeps.
