3 Free Mac Apps Every Developer Should Know About

Every Mac developer I talk to uses a handful of free utilities that make their daily workflow 20% faster. These are not the big IDEs or project managers — they are tiny, focused tools that solve one problem exceptionally well.

Here are 3 free ones we built, open source, available now:

OmniPreview — QuickLook You Actually Want

macOS QuickLook (spacebar) is great, but it does not handle everything. OmniPreview extends it to more file types and gives you larger, higher-res previews.

What it does: Opens any file in a native QuickLook-style preview window. Works with files the system preview handles poorly.

For developers: Quick-peek at images, videos, PDFs, archives without leaving your workflow.

Free on our store (search OmniPreview on Gumroad).

Tempo Pro — Live Weather on Your Desktop

Tempo Pro turns your Mac desktop background into a live weather display. Real-time conditions, animated visuals, all at a glance.

What it does: Shows live weather data as your desktop wallpaper. Updates automatically. Customizable for any city.

For developers: Keep weather info visible during long coding sessions, standup calls, or when working from home.

Free on our store: https://invernomuto2.gumroad.com/l/tanjs?utm_source=devto (search Tempo Pro)

PortGuard Pro — Network Scanner for Your Desk

PortGuard Pro is a lightweight network scanner for macOS. See what devices and services are on your network.

What it does: Scans your local network, identifies devices, shows open ports and services. Simple, fast, no configuration needed.

For developers: Quick security check of your home/office network. See what is actually connected.

Free on our store (search PortGuard Pro on Gumroad).

Why These Matter

These apps solve ONE thing well:

  • OmniPreview: Better file previews
  • Tempo Pro: Weather at a glance
  • PortGuard Pro: Network visibility

No bloat, no subscriptions, no accounts required. Download, install, use.

If you build Mac apps, we would love feedback. Each one is available for free on our store. Open source. No strings.

All apps built by a solo developer. Free because we believe useful tools should be accessible. If you find them helpful, share with a fellow developer.
