Features

Modern Interface

A clean, dual-pane file browser with drag-and-drop transfers, inline previews, and a responsive layout that feels native on every platform.

SFTP, FTP-SSL & FTP

Connect to any server using SFTP, FTP, or FTP-SSL with a fast, reliable transfer engine.

S3-Compatible Storage

Works with Amazon S3, Backblaze B2, Wasabi, DigitalOcean Spaces, and Cloudflare R2 — any S3-compatible object storage.

Native Keychain Support

Credentials are stored securely in your operating system's native keychain — macOS Keychain, Windows Credential Manager, or Linux secret service.

Built-In Editor

Open remote files, make your changes, and save — they upload right back to the server. Syntax highlighting and auto-save make quick config edits painless.

Bookmarks & Favorites

Save frequently accessed servers and directories as bookmarks.

Mirroring That Speaks Every Protocol

Mirror a folder over SFTP, FTP, or S3 — with a full preview, so what you see is exactly what gets written and deleted.
