I’ve always felt like there was no real UI / Screen Design tool for Linux. When I first got started, I used Inkscape, then switched over to Gravit Designer for brief time before falling in love with Figma and sticking with it for the past three years or so.
A while ago, Akira was announced. Unfortunately development is moving very slowly and while it certainly would be a valuable addition to the Linux ecosystem, it seems to be following in the footsteps of Sketch, which in my opinion feels rather clunky when compared to something like Figma. Interestingly enough, however, it was through Akira’s Twitter account that I learned about Penpot and that it would be launching its first public alpha on Feburary 2nd 2021.
Penpot is an open source screen design tool for your team. It is web-based, like Figma, and builds upon SVG as the file format, like Inkscape—and the comparisons to the two don’t end there. If I had to explain Penpot in a single sentence, I would say: it’s what would happen if Figma and Inkscape had a baby.
If you’ve ever used Figma, you’ll feel right at home in Penpot’s UI. From the first screen you see after logging in, to the actual workspace, the components and styles system and especially that colour-picker, it’s all very familiar. Assets and Layers to the right, design and prototyping properties of the currently selected object on the right. In the centre a nearly infinite canvas with full support for artboards (called Frames in Figma).
Unlike Figma, the tools are at the far left of the screen, making good use of the additional horizontal space on today’s widescreen displays – that is if the top bar wouldn’t still be there to show who’s currently working on the file. This way it seems like the arrangement is taking up more space than it needs to. One thing I appreciate a lot over Figma, however, is the dark-themed UI. While I got used to Figma’s stark whites eventually, I still would love to have an option for a dark theme there…
There are a lot of rough edges, but considering it’s an alpha release, those were to be expected. I feel like in general fonts could be slightly bigger and while there are some animations in some places, they all still feel too abrupt and incoherent. The UI also seems to mix native input fields and custom ones in places like the font-family and -size selectors, which felt quite jarring.
I was impressed, however, how smoothly I could move the canvas, zoom in and out, and transform objects. That arguably really important aspect worked very well. I also liked the little onboarding shown after logging in for the first time, although it should probably show something different than reiterating the contents of the landing page in the future. Having a couple of files to play around with from the get-go was also a nice touch—just like that cute little loading animation when opening a file.
Once I started trying out the different tools, the fact that it was still an alpha really started showing. While there are basic rectangle, ellipses, pencil and pen tools, they only manage the bare minimum. I found no way to round corners of a rectangle individually, or only draw a half-circle (the lack of boolean operations making this shape impossible to achieve without drawing it with the pen tool). The pencil tool had an odd offset to it and while the pen tool worked as expected the lack of a preview while manipulating the control handles of a node made it very hard to use.
There was also this strange quirk that while creating a new shape, holding the Ctrl key would lock the aspect ratio, but when resizing an existing object, it was the Shift key. I also didn’t find a way to resize an object from its centre.
I might be spoiled by Figma’s excellent tools, and I’m certain that going with SVG instead of a proprietary file format presents a challenge, I won’t be able to use Penpot for any serious work until its tools get improved (which I’m sure they will over time).
Colours and Effects
I was impressed to see an option to have strokes set to the inside or outside of a shape instead of it being centred, which is notoriously hard to do in SVG. Unfortunately, it seems like the centred stroke is simply being masked when it’s set to display only on the inside, causing its width to be halved.
The colour picker seems very solid and gradients seemed to work well, the handy colour palette at the bottom of the screen bringing back some strong Inkscape vibes from back in the day. I also appreciate the option for a drop shadow, although it unfortunately does not support a negative spread value.
The open source world, and Linux especially need better screen design tools. Inkscape is really powerful, but it leans itself more towards illustration and schematic drawing than UI design—it’s definitely possible, but it takes unnecessarily much time. A component-based approach (which Penpot seems to fully support, including shared libraries!) lends itself well to the way modern applications are built and designed. And while Inkscape keeps getting better and better, it doesn’t support this workflow yet.
I have also long believed that SVG should be the format used for screen designs. Not only for its compatability with the web, but also for its open nature. I know that I can open an SVG in almost any vector drawing application, which leaves me the choice of which tool to work with. Penpot manages to do things with SVG that I didn’t think possible, like supporting multiple pages in a single document and having individual artboards on a page!
I believe Penpot is a great step in the right direction and while it’s true that it can’t hold a candle to Figma, I think it’s only a question of time, if it keeps improving and the open source community steps up—just look at what Blender turned into in the past few years.
I am a little sad that it’s a hosted application that requires a server to run properly, but considering their focus on a team-based workflow, that’s understandable. However, it also means that you’ll have to create a free account (you can also sign in with Google) if you’d like to try Penpot out for yourself—and you definitely should.
I am not associated with Penpot in any way or form and was not asked to write this article, nor did I receive compensation for doing so.
