Open Source Alternatives to Sketch
Transparent & Community-Driven
Replace Sketch with open-source software you can inspect, modify, and self-host. No vendor lock-in, no hidden costs, full control over your data.
Sketch at $12/month ($144/year) is a Mac-only UI design tool. Penpot is a free, open-source alternative that runs in any browser. Figma's free tier covers most UI design needs. For Mac users who want a native app, Sketch's one-time purchase option exists but is being phased out. The UI design market has shifted to browser-based tools, making Sketch's Mac-only limitation increasingly irrelevant.
Open-source alternatives give you something subscription software never can: the ability to inspect, modify, and self-host the code. This means full transparency, no vendor lock-in, and the freedom to run the software on your own terms. The following open-source alternatives have been evaluated for features, community health, and long-term viability.
