Design is no longer confined to glossy magazines or high-priced software. In 2025, the open source community brings innovative, accessible tools that are transforming how designers and developers shape digital experiences. From dynamic UI libraries to AI-powered theme generators, these projects ripple across real-world applications, empowering creativity and customization without the corporate lock-in. Let’s dive into five trending open source design projects that are making waves this year.
1. RetroUI: The Nostalgic Yet Modern UI Kit RetroUI is gaining traction fast, thanks to its blend of React, Next.js, and the versatile shadcn/ui library. It’s not another stuffy UI component pack; instead, it offers components with deep customization that you can tweak directly to fit your brand’s vibe. Imagine a toolkit that lets you channel vintage aesthetics with modern flexibility, ideal for e-commerce sites or content platforms craving personality. Developers love RetroUI for its open approach—nothing is locked away, every piece is yours to adjust and repurpose.
2. Tweakcn: AI Meets Design Customization Jumping onto the trend of AI-enhanced design, Tweakcn’s rise wasn’t accidental—it garnered over 2,500 GitHub stars shortly after its launch. This project enables creators to generate themes powered by AI, which can seamlessly integrate into existing shadcn/ui environments or standalone apps. Think of it as having a design assistant who never tires, helping your website stand out with custom colors, fonts, and styles tailored automatically.
3. Nemo: Middleware for Next.js Developers Next.js has revolutionized React app development, but understanding middleware composition has been a hurdle. Nemo helps developers see middleware as building blocks, easily combining them for streamlined app logic. Its popularity among the Next.js community shines through nearly 5,000 weekly npm downloads. By simplifying how middleware stacks work, Nemo boosts developer velocity, making apps smoother and faster without the cryptic code maze.
4. CourseLit: Digital Product Creation and Commerce CourseLit is changing the game for educators and entrepreneurs with its open source platform to build, manage, and sell digital products. Instead of relying on locked platforms, creators can self-host CourseLit, controlling every aspect of their business infrastructure. This project demonstrates the practical side of design—how well-crafted software serves people in their daily digital commerce journeys.
5. Comp AI: Compliance Made Friendly and Open Compliance might sound dry, but Comp AI spices it up by offering a community-driven, open source platform that automates compliance. It’s an alternative to proprietary tools like Vanta or Drata, featuring active development with over 1,000 commits recently. As enterprises race toward digital safety standards, Comp AI embodies the spirit of open source—collaborative, transparent, and responsive to real business needs.
