Become a sponsor to Rudi K.
Hi, I'm Rudi 👋
I build tools that make life simpler, healthier, and more human.
🪁 My Projects
✏️ LeedPDF
A lightweight, privacy-first PDF annotation and drawing app. Works in the browser or as a desktop app. Free forever and open source.
A high-performance data visualization library for Flutter. It brings the flexibility of the grammar of graphics to mobile and desktop apps with GPU-accelerated charts that are easy to customize.
🧑⚕️Pillow
A health journal app focused on privacy. It combines journaling, mood tracking, guided meditations, symptom prediction, and reminders, with all data stored securely on your device.
☕ Why Sponsor?
If you choose to sponsor me, you'll be helping keep these projects alive and improving. Your support makes it possible to add new features, polish the experience, and experiment with new ideas while keeping everything open source and user-first.
Thanks for considering it. Every bit of support helps me keep building tools that matter. 💚
Reaching 50 sponsors a month will give me the freedom to dedicate consistent time every week to my open source projects. • Regular feature updates and bug fixes for LeedPDF, Cristalyse, and Pillow. • Better documentation, examples, and onboarding so more people can actually use these tools. • Faster responses to issues and pull requests. • Space to experiment with new ideas without worrying about whether I can afford to keep the projects alive. Right now I balance these projects alongside everything else in life. Hitting this goal would let me treat open source like a steady commitment instead of a side project I squeeze in.
