SpacePigeon lets you define full “workspaces” for macOS (which apps to launch, what desktop spaces they use, how windows are laid out, even which URLs open in your browser) — and restore them with a single click or hotkey. It’s a lightweight, open-source app built on Hammerspoon — combining automation power with native macOS feel.
I switch between a few different “modes” on my Mac every day (work, coding, meetings, personal stuff).
Each time I’d end up reopening the same apps and dragging all the windows back into the right Spaces.
Super repetitive and honestly kind of annoying.
So over the past few weeks I hacked together a small open-source tool called SpacePigeon that basically remembers your whole workspace and puts everything back where it was.
Things it can do:
- Save your current layout (apps + windows + Spaces)
- Restore it with one click or a hotkey
- Keep separate presets (like “Work”, “Coding”, “Meetings” etc.)
- Handle external monitors
Example: I hit my “Work” preset and it opens all the usual apps and moves them to the right desktops automatically. Saves me a few minutes every time.
If anyone here lives in Spaces like I do, you might find it useful.
Here’s the repo (MIT, free):

Totally open to feedback — still very much a work in progress.
This solves a very real problem for anyone who context-switches a lot. I tried it with my writing + dev setup and the feeling of everything snapping into place instantly was chef’s kiss. Awesome work.

Who hunted SpacePigeon?
SpacePigeon was hunted by Louis Verstraeten.

Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
