The Best Lunacy Alternatives for Seamless Design Workflows
Lunacy has carved out a significant niche as a free, native Windows application that excels at opening, editing, and saving .sketch files. It’s a true game-changer for design teams bridging the gap between different operating systems, effectively acting as “Sketch for Windows.” With its robust features like automatic Google Fonts downloads, direct CDN asset publishing, and offline functionality, Lunacy solves many pain points in the design-to-development pipeline. However, while Lunacy is powerful, designers often seek other tools that might offer different collaboration features, platform support, or specialized functionalities. If you're looking for a Lunacy alternative, you've come to the right place.
