We often say that if something seems too good to be true, it probably is. But with free software there are some genuinely useful Mac and PC applications to be found often with no strings attached.

In the case of the Open Source and Free Software initiatives, for instance, the whole idea is to make high-quality applications, utilities and programming languages freely available

Just about everyone should be able to use, modify and redistribute them as they wish, without any of the hidden catches associated with standard software licences.

Free Software movement

Until the 1970s, it was quite common for computer software to be used and distributed freely. The original Free Software movement was initiated largely as a reaction against copyright protection in the software industry, which really began in the 1980s.

Open Source

The Open Source initiative is a direct descendent of the Free Software movement. It was first defined in 1998 and is based on the same ‘share and share alike’ philosophy as Free Software, with minor differences in its principles.

In order to qualify as either Free or Open Source software, developers must adhere to strict definitions, most of which refer to use and distribution.

As such, there are very few ‘catches’ for end-users, as the software licences are specifically designed to be non-restrictive and non-discriminatory.

Things to watch out for

Not all free software is so benign, however. Outside of the Open Source universe, there's often an ulterior motive of some kind most free applications and utilities.

Big companies

When big companies make programs free to download, the application itself may be free to use, but the technology behind it is not.

You might get a free web browser or media player, but the company could get an unfair advantage in terms of monopolising the marketplace and controlling formats or content.

Beta software

Beta software is new programs that are currently being developed. As part of their testing, developers often make them available for free. The catch is that you're expected to suggest ways the developers can improve or fix their product.

The software you're using isn't finished yet, which it could mean it may behave unexpectedly or not function correctly. As such, you use it at your own risk.

Not as slick

Some beta software and freeware applications and utilities may look less slick than shop-bought alternatives or they may not be as user-friendly. Usually, it’s easy to overlook these issues.

Security

The main thing to be careful of with freeware is that some applications secretly install other potentially malicious programs on your computer when you run the setup file.

Perhaps the biggest drawback with free software is that it tends to lack the level of technical support you get with commercial products.

Don’t let this put you off, though, wherever you find free software, you’ll generally also find a vast community of fellow users and developers, many of whom will be more than happy to offer free help and advice through forums and discussion boards.
