Manage your Cloudflare R2 buckets and your SFTP servers together in one unified interface. R2 Bucket Boss is a native file manager for Cloudflare R2 buckets and standard SFTP servers. Connect once, then browse, edit, move and share your files without opening a web dashboard or typing a single command. WHY R2 * Zero egress fees. Upload once and share the link as many times as you like. Most object storage charges you per gigabyte downloaded. Not R2. * S3-compatible, so the tokens and tools you already have keep working. * Served from Cloudflare's global network, so a file downloads quickly whether your recipient is in Tokyo or Toronto. * Map your own domain to a bucket and send links from your URL instead of a generic storage endpoint. ONE APP WINDOW HANDLES BOTH PROTOCOLS * R2 buckets and SFTP servers in the same browser, with several sessions open at once * Drag and drop straight to and from the Finder, whole folders included * Drag a file onto a folder to move it on the server, with no download and re-upload * Create R2 buckets without leaving the app * Bookmarks for the folders you actually work in * A transfer queue you can watch and cancel EDIT AND PREVIEW WITHOUT DOWNLOADING * Built-in text editor for remote files, on both SFTP and R2 * Saving an R2 file purges the Cloudflare cache automatically, so the change is live immediately * Image preview that streams from the server: JPEG, PNG, GIF, WebP, HEIC, BMP, TIFF, ICO and SVG, with Fit and Actual Size BUILT FOR PROFESSIONAL WORKFLOWS * POSIX permissions editor with multi-select and recursive apply * Folder sizes calculated in place, everywhere at once or on demand * Duplicate a file server-side, which on R2 is instant no matter how large it is * Copy Web URL for any object, with bucket-aware public and custom-domain links * Purge the Cloudflare cache on demand, or automatically after you change a file * Browse your Cloudflare Stream videos, copy playback URLs and remove old uploads ALL THE POWER OF A DESKTOP APP, ON YOUR IPHONE * The same servers and keys, carried over from your Mac * One-click sync over your local network: your Mac shows a PIN, your phone enters it, and the encrypted server list transfers directly. Nothing passes through anyone's cloud. * Multiple sessions, breadcrumb navigation, text editing and bookmarks on iPhone, with a split-view sidebar on iPad EASILY MOVE BETWEEN MACHINES WITHOUT SKIMPING ON SECURITY * Export your entire server list, SSH keys included, as a single file encrypted with a passphrase you choose * Move it to another machine, import it, and carry on GETTING STARTED WITH R2 1. In the Cloudflare dashboard, open R2 and then Manage R2 API Tokens, and create a token with Object Read and Write permissions. 2. Copy your Account ID from the R2 overview page. 3. Connect to https://ACCOUNT_ID.r2.cloudflarestorage.com and your buckets appear. Already have SFTP servers? Add a host, a username and a password or SSH key, and they sit alongside your buckets in the same sidebar. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
