Firebug
Debug HTML, CSS and JavaScript in any web page

Firebug is a Firefox add-on which integrates a host of essential web development tools into the browser.

A powerful source editor shows you the HTML source as it's being transformed by JavaScript, highlighting changes as they happen so they're easy to spot. You can view the properties of any individual element in a click or two, click on page objects to instantly see the HTML and CSS behind them, and even create, edit or delete HTML elements and see the changes right away.

Firebug's CSS tools make it easy to see which rules are styling individual page elements. Or you can view entire style sheets, if you prefer. If there are problems then you're able to disable any CSS property in a click, just to see how a page appears without them. And not only does Firebug allow you to edit CSS properties, it also knows which keywords you can use, so you don't have to remember every option yourself: just press the Up and Down arrows and the program will cycle through all the possibilities.

Firebug also includes a very powerful JavaScript debugger, which is able to step through scripts, can pause execution on particular lines, break on errors, watch expressions, and more. Or, if everything works, but performance is poor and you're not sure why, then Firebug's JavaScript profiler could help you figure out the problem.

Other tools on offer will help you to check page load times, understand JavaScript, CSS or XML errors, or log in-depth details on what's happening as your page runs.

Version 2.0 extended the addon with JavaScript syntax highlighting, DOM events and JavaScript Expression inspectors, pretty printing, and improvements to HTML searching, code auto-completion, and more.

Version 2.0.10 (Changelog)

Verdict:

Firebug offers an excellent set of web development tools, and despite all its power remains generally very easy to use

Unreal Engine 4.8

Free Full Commercial Software

Unreal Engine is Epic Games' game engine, a powerful suite of tools for developing anything from basic 2D games to professional RPGs, first person shooters and whatever else you like.

Wide standards support - DirectX, OpenGL, JavaScript/ WebGL - means your projects can be targeted to almost any platform: consoles, iOS, Android, Windows, OS X, Linux, HTML5 browsers and more.

There's a vast amount to learn, of course, and that's even before you start building your game. But there's plenty of documentation, tutorials, demos and sample projects to point you in the right direction.

The package is now entirely free, too - no annoying limitations, nag screens or anything else. Epic now only requires that you pay a 5% royalty after the first $3,000 of revenue per product per quarter. And even then, you "pay no royalty for film projects, contracting and consulting projects such as architecture, simulation and visualization."

8.48 brings:
    - Optimized grass rendering and procedural foliage system preview
    - Plugins available in Marketplace
    - Improved accuracy for motion blur
    - New Tone Mapper
    - Support for all the latest VR hardware including Oculus Rift, Samsung Gear VR, Steam VR and HTC Vive, Leap Motion, and Sony's Project Morpheus for PlayStation 4
    - "Scrubbable" network replays with rewind support and live time scrubbing
    - Visualize the memory footprint of game assets in an interactive tree map UI
