Cobble is a modernized, cloud-enabled hand note-taking software forked from the amazing Xournal++ project. It is designed to offer a more premium, modern visual experience with built-in cloud syncing out of the box.
Cobble builds on the rock-solid foundation of Xournal++ and introduces several new features:
- Cloud Synchronization via Supabase: Seamlessly backup and sync your
.xoppdocuments to the cloud. The app uses an asynchronous C++ save job to upload files directly to a Supabase storage bucket without freezing the UI, providing a smooth, integrated cloud experience. - Modern Dark Theme by Default: Cobble ditches the legacy white canvas for a sleek, default dark mode. The UI features a deep dark-grey
#1e1e1ecanvas and a matching#2d2d2dtop menubar/toolbar, heavily inspired by the VS Code aesthetic. - VS Code Inspired Color Palette: The default pen colors have been completely overhauled. Gone are the harsh primary colors; Cobble features a curated, pastel-infused dark mode palette that makes your notes look beautiful and easy on the eyes.
- Refined Branding: A fresh new logo and modernized UI elements.

Cobble is built directly on top of Xournal++. All core stroke recognition, PDF annotation, and rendering logic are the phenomenal work of the Xournal++ contributors. Stroke recognizer and other original parts are based on Xournal Code, which you can find at SourceForge.
