Creately vs Affinity Designer

The templates are well thought-out and actually helps you get started. Not like many other sites where the details are already filled in.

Consist with an example diagram which we can use to draw the diagram.
Most required diagrams are available.

Does not require flash.

Easy to use drag and drop interface and a contextual toolbar that shows you all the important actions when you select an object. The automatic creation and connecting of next object alone saves tons of time.

You can invite anyone by their email addresses to collaborate with your diagram. You can see others' changes to the diagram real time with the Creately Online and Desktop app.

You can't edit diagram using the apps but provides a nice clean interface to view, share and comment on them.

Creately supports SVG (Scalar Vector Graphics) import and export to make your diagrams more attractive. It allows you to re-size your diagram as much as you want without getting it messed up.

Rather than a monthly subscription based model, Affinity Designer instead has a one-time fee ($49.99).

The user interface of many graphic editing software programs can often be discouraging for beginners. Affinity Designer, however, has a very well laid out and intuitive user interface with a small learning curve.

Extensively tweakable brush types, color options...

An object can easily be transformed into a slice that can then be exported in various sizes end formats in 1 go. E.g. Export slice A as PNG 1x, 2x and 3x AND GIF 1x AND SVG.

Symbols can get individual property changes (color, shape, layer effects, fonts text...) while the other properties stay linked with the base symbol.

For those working in mixed environments that aren't 100% MacOS, you'll find devoting yourself to Sketch.app brings with it...pain. If this fits the bill for what you need feature-wise and you're in a mixed OS environment, it's a very capable replacement for Sketch.app. Note that it doesn't have all the same features, but then again it doesn't need all the same features. Short of organization differences inside the document you're working on, there shouldn't be anything you can't do with Affinity Designer that you could have with Sketch.

Available on both Windows and MacOS

In the era of "retina" displays, 4k UHD, 5k, and even 8k, Scalar Vector Graphics - independent vector images that can scale to any resolution without any display quality loss - are more important now than ever.

And this tool is quite capable of rendering true SVG output suitable for consumption at any display resolution (not a big bunch of rasterized bits in the document, actual paths, points, etc.).

Unlike some design tools, Affinity Designer isn't trying to be all things to all people. It's focused on its main area of expertise: vector graphics. That's not to say you can't use a raster image (think a photo in *.jpeg format for example), but it's not built to do much with that other than using it somewhere amidst the layers and that's about it.

These are companion apps & switching between them is built in - Photo is a very powerful raster tool with a feature set close/better to Photoshop, it will also use some Photoshop plugins. This allows you to add-on powerful raster capabilities if you want them - put doesn't force you to.

Best I have seen in a non Adobe app, you can use most of the Photoshop mock-ups and templates easily. Opens most Adobe files to a level to be able to effectively use the content. Allows cross team collaboration across tool-chains.

The new version 1.5 has a very powerful feature set such as support for symbols and asset windows, as well as constraints controls and improved export options. This all adds up to an interesting alternative to Adobe Illustrator.
