Key Differences

Bootstrap Icons are designed specifically to complement Bootstrap's style and are provided as SVG files. This means they are scalable, crisp on all screen sizes, and easy to style with CSS. They are lightweight and focus on simplicity, making them ideal for projects that want minimal overhead and a consistent look with Bootstrap components.

Font Awesome offers a much larger icon set and supports both SVG and web font formats. This gives developers flexibility to use icons as fonts or SVGs. Font Awesome also includes advanced features like icon layering, animation, and icon kits, which allow for more creative and complex icon usage. However, this comes with a larger file size and sometimes more setup complexity.

In terms of licensing, Bootstrap Icons are fully open source under the MIT license, while Font Awesome has both free and paid Pro versions, with the Pro version unlocking many additional icons and features.
