Charles (64-bit)
A powerful HTTP proxy/ monitor for developers

Charles is a powerful and versatile Java-based HTTP/ HTTPS proxy which can display a great deal of information about your web traffic. And that includes JSON, JSON-RPC and SOAP, Flash Remoting (AMF0 and AMF3) and more, as well as the regular HTTP/ HTTPS requests and responses.

The program includes a Firefox addon, which means there are no real configuration hassles. Just launch it, approve the addon, and Charles will immediately begin tracking your Firefox activities. Browse a URL of interest and you'll be able to watch the traffic details as it's analysed in real time.

This starts with a Structure tab, where your browsing is organised by URL. Clicking any of these provides a list showing every element downloaded, with assorted details (response codes, MIME types, header and body sizes, download times and more). A Chart tab gives you a more visual check on download times, while an Overview provides plenty of extra timing information (connection times, latency, DNS delays and more).

Alternatively, clicking the Sequence tab displays all your traffic at once. This is probably way too much information, but fortunately you can filter it to display traffic related to a domain, a file type, a response code or whatever else you like. Again, any particular request can be analysed in multiple ways, this time even including a Response tab which can display the response in its raw form, as text, hex, an image (if appropriate) and more.

There are also plenty of useful tools. A bandwidth throttling option helps you see how your site feels on slow internet connections; a "repeat" option lets the program re-run a request at a click (no need to reset and reconfigure the same web page each time); "repeat advanced" allows you to make repeated and concurrent requests, for load testing; and of course you can intercept and edit particular requests as you like.

But perhaps best of all, while this sounds like it's going to be complex, it really isn't. The author says "Charles is intended to be a dive-in piece of software", and we think he's right. There's plenty to learn, but no frustrating setup or configuration issues - we were using the program productively right away.

Verdict:

If you need more than browser addons like Live HTTP Headers can provide, take a look at Charles. It's not cheap, but it's well designed, easy to use, and you get plenty of power for your money.

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."

    - Optimized grass rendering and procedural foliage system preview
    - Plugins available in Marketplace
    - Improved accuracy for motion blur
    - New Tone Mapper
