SteadyMount mounts SFTP, WebDAV, and FTP servers as native Finder drives on macOS, using Apple's File Provider API (NSFileProviderReplicatedExtension) instead of a FUSE kernel extension. That's the same framework iCloud Drive uses, so files download on demand and the mount survives macOS pausing the extension to save power, instead of throwing a "server disconnected" error. Protocols: SFTP (password or ED25519/RSA key auth, TOFU host key verification), WebDAV (Basic/Digest, HTTPS), and FTP (standard or anonymous login, with FTPS). Why it exists: Mountain Duck is the closest comparable tool, but moved existing perpetual-license customers onto a subscription in late 2025, which caused significant backlash. SteadyMount is a one-time purchase: free for the first 30 days, then one connection stays free permanently, or $27.99 unlocks unlimited connections with no recurring fee. Requires macOS 14 Sonoma or later.

SteadyMount's answer
SteadyMount uses Apple's File Provider API (NSFileProviderReplicatedExtension) instead of a FUSE kernel extension, the same approach iCloud Drive uses. That means no kernel extension install, no Recovery-mode reboots, and files download on demand rather than syncing the whole remote server locally. The mount also self-heals: when macOS pauses the extension to save power, or a connection drops, SteadyMount reconnects silently instead of showing a "server disconnected" popup. And it's a one-time purchase with no subscription.

SteadyMount's answer
The closest comparable tool is Mountain Duck, which moved existing perpetual-license customers onto a subscription in late 2025 and caused real backlash. SteadyMount is a one-time purchase instead: free for the first 30 days, then one connection stays free permanently, or $27.99 unlocks unlimited connections with no recurring fee. Compared to free options like macFUSE + sshfs or rclone mount, SteadyMount needs no kernel extension and doesn't show the disconnect popups those tools are known for, because it's built on Apple's native File Provider API.

SteadyMount's answer
Mac users who need to work with files on a remote SFTP or WebDAV server as if they were local: developers deploying to a VPS, web developers editing files on shared hosting, self-hosters, and sysadmins. Also anyone who was using Mountain Duck before its 2025 subscription change and wants a one-time-purchase alternative that behaves the same way in Finder.
Axcrypt's answer:
Personal users protecting documents like IDs, financial papers, medical files, and cloud backups.
Professionals & freelancers who share confidential files with clients and need secure workflows.
Small businesses & teams needing quick, dependable file-level encryption without enterprise complexity.
Non-technical users who want strong protection but prefer a clean, simple interface.
SteadyMount's answer
The macFUSE-based tools that used to be the standard way to mount SFTP on a Mac (osxfuse + sshfs, rclone mount) became increasingly painful: macFUSE was pulled from Homebrew, kernel extension installs meant Recovery-mode reboots, and mounts routinely threw disconnect popups. Around the same time, Mountain Duck, the main app using Apple's newer File Provider API instead of FUSE, moved existing perpetual-license customers onto a subscription. SteadyMount was built to combine the File Provider approach (no kernel extension, no disconnect popups) with a one-time purchase instead of a subscription.
SteadyMount's answer
Swift and SwiftUI for the menu bar app. Apple's File Provider API (NSFileProviderReplicatedExtension) running in a sandboxed XPC extension for the actual mounting. Citadel (a Swift SSH library built on SwiftNIO) for the SFTP backend, and URLSession with custom WebDAV methods (PROPFIND, PUT, MKCOL, MOVE, DELETE) for the WebDAV backend. Credentials are stored in the macOS Keychain, shared across the app and extension via an App Group.

With regard to encryption tools, I use AxCrypt, which is cross-platform, but isn't free in that form. It would though encrypt each file in-place, without need for a dedicated folder or vault and encrypted file will sync with OneDrive, via the standard sync client. It would also allow you to share encrypted files with others, without giving them your encryption password. Source: over 4 years ago
