We regularly feature commercial software on AppStorm, so decided it was time to bring a roundup of completely free (and often open source) apps to your attention. If you’re on a budget, you’ll be pleased to know that a variety of great OS X software is available free.
Applications are broken down into various categories, with each one containing a ‘featured’ app and several other free solutions. I hope you find something useful, and do let me know if your favorite freeware app isn’t on the list!
Web Browsers

Firefox
Firefox
There’s a reason why Firefox has stormed ahead over the past few years to take such a large share of the browser market. It’s fast, completely free, and works on any platform available.
A variety of different extensions are available, taking the functionality of the browser far beyond the basics. Whilst lacking the scorching speed of the latest Safari beta, it offers a brilliant alternative if you’re looking for a free, open source browser.
- Camino – A good looking Mac-styled browser, built on the Firefox engine.
- Safari – The default browser included with OS X, with a bunch of new features in the latest release.
- Opera – A powerful browser with a few new interesting features; speed dial, search shortcuts, and a tab trash can.
- Omniweb – Taking a different approach, and assisting you with online research
- Fluid – A site specific browser, allowing you create a separate app for various websites.
Email & Communication

Thunderbird
Thunderbird
Developed by the same people behind Firefox, Thunderbird is a worthy alternative to Mail.app on the Mac. It has a lovely interface, with in-built junk filtering and anti-phishing support.
With additions in the new version, it’s easier to prioritize and find your important email with tags. Extensions also work well, allowing various extra features to be added.
- Adium X – The ultimate instant messaging client
- Skype – For free computer-to-computer calls, and great video conferencing

Music & Audio

Spotify
Spotify
Quickly making a name for itself as a competitor to Last.fm, Spotify allows you to stream almost any song you can imagine via the internet. Access is free, though you’ll need to listen to a short advertisement every few songs.
I’m still fond of owning my own music, but Spotify compliments iTunes excellently.

- iTunes – The de-facto music player for OS X, Windows and iPod users

Photography

Picasa

Recently featured in our photo client roundup, Picasa is designed and owned by Google. It offers a bunch of great features, and is also capable of sharing photos online.
If you’re not a fan of iPhoto, Picasa has an equally impressive interface, a solid way to organize photos, and various editing tools.

File Sharing & FTP

Transmission
Transmission
Transmission is a fast, easy, and free multi-platform BitTorrent client. It’s fast, incredibly simple, and offers the easiest experience I’ve ever seen for dealing with torrent files.
Not enough? How about encryption, a web-based interface, peer exchange, and UPnP and NAT-PMP port forwarding?
- Cyberduck – A free alternative to commercial FTP applications
- Filezilla – Great for accessing FTP servers, and completely cross-platform
- Acquisition – In-built torrent searching and integration with iTunes

Office & Text Editing
