rsync

croc is a command-line tool for transferring files and directories between computers using a short code phrase rather than manually configuring SSH servers, firewalls, keys, or IP addresses. It uses peer-to-peer connections with relay fallback and end-to-end encryption based on PAKE, supports resumable and multiple transfers, and does not require a local server or port forwarding. The tool supports Windows, Linux, macOS, and browser clients, can use proxies such as Tor, and allows custom relay servers.

Capistrano is a remote server automation and deployment tool written in Ruby. It extends the Rake DSL with methods for running commands on servers, including executing tasks across hosts and roles in parallel, and can deploy applications written in any language. Its documentation covers configuration, rollbacks, authentication and authorization, remote commands through SSHKit, task hooks, filtering, custom source-control plugins, and framework-specific tasks.

ovnfs is a command-line tool and background daemon that provides isolated, copy-on-write checkouts of folders and Git repositories without copying their contents. Agents work in a checkout exposed through a single mount using NFSv3 on macOS, FUSE on Linux, or SMB/WinFsp on Windows; changes can be inspected as diffs and merged back with a three-way apply. Checkouts can also be snapshotted, forked, attached to another machine with lazy first-read transfer, or used for disposable command runs. ovnfs isolates files rather than processes, so it is not a sandbox. The project is distributed under the MIT license.

gdirect is a Rust command-line tool for browsing, downloading, uploading, and mounting Google Drive. It can export Google Docs files to formats such as PDF, resume interrupted transfers, verify completed downloads against Drive checksums, and manage multiple Google accounts. For transfers, gdirect scans reachable Google front ends, tests them with TLS, Drive API, and download checks, and routes requests through verified endpoints. It supports multi-connection downloads using pinned libaria2, automatic retries between endpoints, and optional use of a relay or Google-only routing. Mounting uses rclone, with NFS on macOS and FUSE3 on Linux; local writes are cached and uploaded in the background. The project provides prebuilt binaries for macOS, Linux, and Windows, plus source-build instructions.

Escrcpy is an open-source graphical interface for displaying and controlling Android devices through the scrcpy engine. It provides an embedded mirror with screen-fitting and orientation handling, configurable mappings for touch, joystick, swipe, scrolling, and automation, simultaneous control of multiple devices with broadcast input, batch screenshots and APK installation, and a draggable control bar for device operations. It also supports wireless ADB connections with LAN discovery and Gnirehtet reverse tethering, visual step-by-step automation with screen-image recognition, global shortcuts, and an MCP-based AI assistant with multi-model chat. Released packages are available for manual installation, with macOS installation through Homebrew; advanced features from the private EscrcpyX extension are paid, and the project states that updates are irregular.
