Inkscape vs Affinity Designer

Inkscape is GPL-licensed and maintains public repositories.

Inkscape supports many common formats for import (including SVG, Photoshop and Illustrator) and its plugin architecture allows more to be added.

Files can be exported and saved as a "normal" svg, png, jpg, bmp etc. file.

Pre-built binaries are available for Windows, Mac and Linux. Inkscape can be built from source on additional platforms.

Its uses the X11 icon theme and desktop theme(GTK).

A very powerful software that can do pretty match anything!

This tool is extremely handy and can not be found in any other vector graphics programs out there.

Extremely powerful menu that offers more than 30 powerful Live Path Effects to apply to paths vastly enhancing the application functionality.

Extremely handy features when building complex graphics using Inkscape.

The new 1.0 beta 2 version finally got support for dark theme which normally is only available for commercial software like Affinity Serif, Adobe Illustrator.

Inskape got UI update: new dockable dialogs.

Vector graphics can be created and edited with Inkscape.

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.
