A cloud file manager built for real work
Nubbo gives you an advanced file browser that connects all your providers in one interface. Move between buckets, folders and files without switching windows. Every transfer uses presigned URLs: your files never pass through our servers.
- Drag and drop uploads powered by presigned URLs for maximum speed
- Preview images, video, audio and PDF files, and edit code and Markdown directly in the browser
- Organize with color-coded labels and favorites, hide what you do not want to see, and restore or delete from the trash
- Advanced search across providers with filters by kind, size, date, labels and saved searches
- Automatic multipart uploads for large files (up to 5 TB per object)
