This is a Free and Open Source RAD tool for Custom Tkinter. This software allows you to create complex UI faster than ever⚡
I built CustomTkinter Builder when I was around 15 years old. Looking back, the code I wrote is quite messy, making it incredibly difficult to fix issues and refactor today. Still, I have learned a lot from this project.
During development, I realized that CustomTkinter itself can be buggy, requiring a lot of workarounds to function as desired. The original maintainer has also lost interest in continuing its development. While a community-driven fork called Custom2kinter has been launched, I don't see much point in building on it right now. For larger projects, the library's lag is a real issue - it is CPU-based and draws everything on the tkinter canvas to achieve its modern look. While I still love tkinter for its simplicity, libraries like Flet, Kivy, and PyQt5 are much faster and more efficient (although the learning curve is a bit high).
I originally started this project because there weren’t any free and open-source options available; the only feature-rich tool at the time was paid software, CTkDesigner. However, just a few days ago, I saw a new free and open-source tool named CTkMaker that looks very promising. The developer mentioned in a CustomTkinter discussion that the whole thing was "vibe coded" in 17 days, which I appreciate the honesty of. It took me two months of development during my summer vacation to reach a similar level! I recently tried refactoring my own code with the help of AI coding agents, but the codebase is so tangled that even they are having a hard time. Moving forward, I highly recommend checking out tools like CTkMaker.
Another major factor for this repository going dormant is that I am finishing my schooling next year. I am currently enrolled in coaching classes for college entrance exams, which takes up all the time I used to spend programming.
For all the reasons mentioned above, CustomTkinter Builder will no longer be receiving updates. Thank you to everyone who used and supported the project.
