Overview
Bubble
Bubble gives you the power to build complex web applications like marketplaces, social networks, or CRM tools without writing a single line of code. You can design your interface with a drag-and-drop editor and define your app's logic through a visual workflow builder. Unlike simple website builders, it provides a robust hosted database, allowing you to manage user data and dynamic content effortlessly.
You can scale your application from a simple prototype to a venture-backed startup using its integrated hosting and version control. It solves the technical barrier for entrepreneurs and internal teams who need to launch custom software quickly and affordably. Whether you are building a private tool for your team or a public-facing platform for thousands of users, you have total control over the design and functionality.
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.
