Browse and manage your Amazon S3 buckets with blazing speed. Built with Rust for O(1) folder navigation across millions of objects. The best free alternative to Cyberduck and CloudBerry for AWS S3 file management.
Why Brows3 exists and what makes it different
Traditional Amazon S3 file browsers and AWS S3 clients suffer from slow performance when navigating deep folder structures or listing large numbers of objects. Whether you're using the AWS Console, Cyberduck, CloudBerry, or other S3 GUI tools, you've likely experienced frustrating wait times. Brows3 is a free, open-source S3 desktop client that completely rethinks the cloud storage browsing experience.
After an initial index, folder traversal happens in O(1) time. No more waiting for loading spinners when clicking through directories.
Perform instant, localized searches across your entire bucket. Find any file in milliseconds, even in massive datasets.
Brows3 populates its local cache in the background while you work, ensuring your view is always synchronized without blocking your interaction.
Our custom-tuned virtualization engine handles lists of 100,000+ items with silky-smooth scrolling at 60fps.
