Overview
Proto.io
Proto.io gives you the power to create high-fidelity prototypes that look and feel like the finished product. You can build complex interactions, transitions, and animations for mobile apps and web interfaces using a simple drag-and-drop editor. It eliminates the gap between static designs and functional reality, allowing you to test user flows and gather feedback before developers write any code.
You can start from scratch or import your existing assets directly from Figma, Adobe XD, or Sketch. The platform is designed for UX designers, product managers, and entrepreneurs who need to communicate their vision clearly to stakeholders. Whether you are building a simple landing page or a complex multi-screen mobile application, you can simulate touch gestures, keyboard inputs, and sensor events to ensure your user experience is flawless.
Sketch
Sketch provides you with a powerful, native macOS environment to design everything from simple icons to complex design systems. You can create precise vector graphics, build interactive prototypes with logic-based transitions, and manage reusable components through a robust Symbols system. The platform is built specifically for the Mac, ensuring a smooth, high-performance experience while you work on high-fidelity user interfaces.
Beyond individual design, you can collaborate with your entire team through a web-based workspace. This allows you to share documents, gather feedback via comments, and hand off production-ready assets to developers directly in a browser. Whether you are a solo freelancer or part of a large design department, you can maintain a single source of truth for your projects and scale your design language across multiple platforms.
