RapidRAW

A beautiful, non-destructive, and GPU-accelerated RAW image editor built with performance in mind.

RapidRAW is a modern, high-performance alternative to Adobe Lightroom®. It delivers a simple, beautiful editing experience in a lightweight package (under 20MB) for Windows, macOS, and Linux.

I started developing this project as a personal challenge when I was 18. My goal was to create a high-performance tool for my own photography workflow while deepening my understanding of React, WGSL and Rust, with the support from Google Gemini.

It prioritizes speed, a beautiful user interface, and powerful tools that let you achieve your creative color vision quickly. <br><br> RapidRAW is still in active development and isn't yet as polished as mature tools like Darktable, RawTherapee, or Adobe Lightroom®. Right now, the focus is on building a fast, enjoyable core editing experience. You may encounter bugs - if you do, please report them so I can fix them :) Your feedback really helps! <br><br> </details> <details> <summary><strong>Recent Changes</strong></summary>
