It is an amazing free tool that I use when I have to open sketch files on a PC. Maybe it is not the best UX prototyping tool in the marketplace but it is free that may be very useful for urgency or if your Mac is broken. Review collected by and hosted on G2.com.

It is hard to say something negative for a tool that is is free but if it will be better if it could have all the characteristics that the Sketch app has...but maybe then it has to be named Sketch for PC. It has to improve the symbols panel and some other Sketch characteristics to be totally compatible with Sketch files. Review collected by and hosted on G2.com.

Navigating the interface is very easy

Drawing complex shapes is a walk in the park

Exporting objects individually or in groups is straightforward

The ability to export in a variety of file types (for free) is awesome

The constant logging out of the account can get annoying Review collected by and hosted on G2.com.

I like how it has built in UI kits and wireframing tools for quick prototyping Review collected by and hosted on G2.com.

Sometimes fonts will disappear when you import a file from Sketch. It will say the correct font but display in a stock sans serif Review collected by and hosted on G2.com.

Ease to use interface. Fast and lightweight software. Its the best alternative to sketch app for MAC OS. I have personally found it very simple and feature centric tool. Review collected by and hosted on G2.com.

1. If it has plugins features where the user can add more tools and features that will be great addition.

2. There is no cross-application import/export of other file formats Review collected by and hosted on G2.com.

Lunacy solves a critical problem - editing sketch files in Windows. I was thrilled when I found it because I had no other option to edit sketch files. The team behind the tool has been rapidly improving it. It has all the tools I need. Review collected by and hosted on G2.com.

I still get critical performance issues when opening larger files, to the point where the app crashes randomly. Plus, there are more than a couple of UI bugs, for example, minimizing and maximizing windows leads to some weird flickering and even parts of the UI disappearing. Review collected by and hosted on G2.com.

It is free and accessible to all. Lunacy is constantly being updated, and the developers are listening to their audience. You can see problems from the forums being addressed in each build (and it is updating constantly). I love that I have a viable option for working on Sketch files on my Windows machine.

There are a few hiccups when using Lunacy as it's still being developed and the kinks are being ironed out/ However, I am confident in the development team and enjoy having access to the beta versions of each build. Review collected by and hosted on G2.com.

The app quickly lets you choose what you want to do. An iphone 8 sketch? a Mac background? an Icon set? A windows wallpaper? an Iphone X background?

Just choose exactly what it is that you want to do and the app will let you work your vision and export your file.

It has some of the basic needed features, like basic drawing, geometric figures, coloring & coding, and image importing.

It's a very small file, and it's not a resource hog. All it took was a one 11mb download and a very small installation file & I was sketching 5 minutes later without having to worry about giant, poorly optimized files eating all of my PC's resources. Review collected by and hosted on G2.com.

It's not as intuitive and easy to use, at first sight, the software is more intimidating to use than basic image editors and it should aim to correct this.

Some of the features are very barebones, like import image basically just puts the image on the screen instead of letting me decide how I want to import it beforehand.

Drawing, coloring, and text options are again lacking additional features and a more friendly UI and rely on the user having a deeper understanding of customization and previous experience.

It could use more export options to different formats. Review collected by and hosted on G2.com.

With Lunacy, from Icon( now we can open Sketch files from a Windows environment and:

- Organize pages and artboards.

- Draw, design, align objects.

- Edit CSS, XAML code.

- Import or export elements in JPEG, JPG, PNG with transparencies and even SVG.

- Typographic tools of all kinds.

Additionally, you have serious and consistent support behind it. It is possible to download it for free from the official website. Something very positive to save some money. Review collected by and hosted on G2.com.

At the moment, there is only an installable version and a portable one on the official website. It would be great to do it from the browser without needing to install anything on the machine and use it simply with an Internet connection. Similarly, in Lunacy, we still find some errors that do not ruin the experience for us, but they should gradually be resolved or an update should be released for these bugs (mainly related to the drawing options of certain shapes and figures, or the cutting options, which at least I have not been able to locate).

Took me 5 minutes to figure out, after that allows you to quickly produce mockups. You can save straight to the CDN for rapid sharing. And it's free. Review collected by and hosted on G2.com.

One irritating bug: cursor is not 'background aware' so editing text on a black background is a bit irritating. Review collected by and hosted on G2.com.

Clearly what calls users to come for "Lunacy" is the ability it has to open and save .sketch files. What others say does not bother me. Many come for that main reason. Execente reason.

It has the facility to visualize CSS and XAML files.

This application brings a very useful tool "mascara" facilitates jobs.

Cleaning, precision, very few errors, ideal for web design. Create icons and edit them to your liking, even change the color with icons8.

the computer does not hang Work smoothly with your computer.

It has its own system of updates for the sources. Use the Google engine to search the sources. Wonderful this.

You can download it for free. I have not tried it on MAC but on Windows it's great. It is very compatible with most operating systems.

Is it free I already mentioned it? Save money with this and edit by investing little money. It's almost the same as ADOBE. Review collected by and hosted on G2.com.

Problems with reproduction and undoing.

You can only explore SVG and PNG, that's not very good.

Put cutting tool on it, it's nowhere to be found. Review collected by and hosted on G2.com.
