CoreUI is fully compatible with Bootstrap, but it’s more than just a theme or UI extension — it’s a professionally developed and maintained system that addresses many of the limitations developers face with Bootstrap alone.

Key differences between CoreUI and Bootstrap:

• ✅ Framework-native versions – CoreUI offers official libraries for React.js, Vue.js, and Angular, while Bootstrap depends on third-party community plugins for framework integration.
• 👨‍💻 Full-time maintained project – CoreUI is not a community-only initiative. It’s developed by a dedicated, full-time team focused on long-term evolution and support.
• 📦 More built-in components – CoreUI includes many components not present in Bootstrap by default, such as range sliders, multi-selects, and step-based form wizards.
• 🛠️ Sass Modules support today – CoreUI already supports Sass Modules out of the box, a feature that Bootstrap plans to introduce in version 6.
• 🌍 Modern RTL/LTR support – CoreUI uses CSS logical properties to provide seamless RTL and LTR layout support for multilingual and internationalized apps.
• 🔒 Long-Term Support (LTS) – While Bootstrap 3 & 4 LTS is now a paid service via HeroDevs, CoreUI continues to offer long-term support without additional cost.

Whether you're starting a new project or migrating from Bootstrap, CoreUI gives you a powerful upgrade path with more features, framework bindings, and peace of mind for long-term maintainability.

CoreUI is designed as the extension of Bootstrap. Special thanks for Bootstrap team and Bootstrap's contributors.

CoreUI is an MIT-licensed open source project and is completely free to use. However, the amount of effort needed to maintain and develop new features for the project is not sustainable without proper financial backing. You can support development by buying the CoreUI PRO or by becoming a sponsor via Open Collective.
