Alto keeps folders on your computer in sync with your cloud storage, such as Google Drive, Dropbox, Proton Drive and more.

• True two-way sync. New files, edits and deletions go both ways.
• All your clouds in one place. Connect as many accounts as you like, across different providers, and sync folders from all of them at once.
• Safe across several computers. Before overwriting or deleting anything, Alto checks that things haven't changed since it last looked, so a change made on another computer in the meantime is never lost.
• Shared exclusions. Skip files with .gitignore-style patterns in the folder's .altoignore. It syncs too, so every computer skips the same files.
