Birdfont

1. Cross-platform compatibility: Birdfont is available for Windows, macOS, and Linux, while FontCreator is only available for Windows. This makes Birdfont more accessible to users across different operating systems.

2. Free version availability: Birdfont offers a free version with basic functionality, allowing users to try the software and create simple fonts without any cost. FontCreator, on the other hand, is a paid-only software, which can be a barrier for hobbyists or those just starting with font design

3. Simpler learning curve: Birdfont generally has a simpler interface and is often considered easier to learn for beginners. While it may not have all the advanced features of FontCreator, its straightforward approach can be advantageous for those new to font design or those who prefer a more streamlined workflow
