What is Icons8 Lunacy and how does it work?
Lunacy is a native desktop design application from Icons8, running on Windows, macOS and Linux. It handles UI design, vector illustration, components, shared styles and prototyping, and its distinguishing trick is that it reads and writes Sketch's file format directly.
The second differentiator is the built-in asset library. Icons8 sells icons, illustrations, photos and fonts, and Lunacy puts them inside the canvas, so placing an icon does not mean leaving the app, downloading a file and dragging it back.
Icons8 Lunacy standout strengths
The Sketch compatibility solves a real and annoying problem. Sketch is macOS only. Design teams still hold years of .sketch files, and anyone on Windows or Linux who inherits one has historically had bad options. Lunacy just opens it, edits it, and saves it back.
The pricing model is unusually honest. The editor is free for commercial use with no watermark and no export limit. Icons8 monetises the assets and the cloud storage instead of holding the design tool itself hostage, which is the opposite of how most of this category works.
Being native also matters more than it sounds. On an older laptop, a large file in a browser-based editor becomes sluggish in a way that Lunacy simply does not.
Icons8 Lunacy weaknesses and drawbacks
Collaboration is the gap that decides whether you can adopt it. Figma won its market on realtime multiplayer editing and shareable links that anyone can comment on. Lunacy has cloud documents and some multiplayer, and it is not close to the same experience. If your work involves designers, PMs and engineers in a file at once, this will frustrate you.
The free plan's limits sit exactly where a small team starts to grow. 10 cloud documents and 3 team members is fine for solo work and cramped for a studio, so the cloud subscription becomes effectively mandatory rather than optional once there are four of you.
The asset library is the same story. Plenty is free, the strongest icons and illustrations require the graphics subscription, and that is the point of the whole product from Icons8's side.
The plugin ecosystem is the other real limitation. Figma's plugin library covers content population, accessibility checking, icon management and dozens of niche workflows. Lunacy's does not, so anything you currently solve with a plugin needs checking before you switch.
Icons8 Lunacy pricing & plans (2026)
The editor is free, including for commercial use. Icons8 lists a personal cloud subscription at roughly $4.99 per month or $47.99 per year, and a graphics asset subscription at roughly $9.99 per month or $95.99 per year. The free tier includes 10 cloud documents and up to 3 team members. Check the Icons8 site for current numbers, since these have moved before.
Lunacy fits a solo designer or small studio on Windows or Linux, anyone who has to work with legacy Sketch files off a Mac, and anyone who wants a capable design tool without a monthly bill. It does not fit a team whose workflow depends on realtime collaboration, and it does not fit anyone deep in a Figma plugin stack.

Icons8 Lunacy review: final verdict
Lunacy is the best free design application most people have never tried, and the Sketch compatibility on Windows and Linux is a genuinely unique capability. Icons8 monetises assets and storage rather than the editor, so the free tier is a real tool that produces shippable work.
It loses marks where teams live: collaboration, handoff and plugins. Those are the exact reasons Figma took the market, and Lunacy has not closed that gap.
4.1 out of 5. An easy recommendation for solo designers and anyone stuck with Sketch files on the wrong operating system. A harder one for teams.
