DiffSSH vs Sandbox Relay

DiffSSH turns your iPhone and iPad into a proper Git review tool for the servers you already work on. Connect over SSH, open a repository, and review every change with the clarity of a desktop client - no laptop required. REVIEW CHANGES LIKE A PRO • See staged and working-tree changes in a clean, Source Control view. • Group changed files into a folder tree, or switch to a flat list - your choice. • Stage and unstage individual files, whole folders, or everything at once with a swipe. • Tap any change to open a full diff with syntax highlighting, word-level highlights, line numbers, and green/red gutters. EXPLORE THE WHOLE REPOSITORY • Browse a lazily-loaded file tree and open any file in a fast, read-only viewer. • Walk the commit history as a graph - branches, merges, and refs shown at a glance. • Tap any commit to inspect exactly what it changed. A REAL TERMINAL, BUILT IN • Run commands in a live, interactive shell scoped to your repository. • Sessions are persistent server-side via tmux or GNU screen - disconnect or background the app and your shell keeps running. Reconnect and pick up exactly where you left off. SECURE BY DESIGN • Connect with password or private-key authentication. • Credentials are stored in the iOS Keychain - never sent anywhere but to your own servers. • No accounts, no analytics, no tracking. Your data stays between your device and your servers. SYNTAX HIGHLIGHTING FOR THE LANGUAGES YOU USE Swift, JavaScript, TypeScript, Python, Ruby, Go, Rust, Java, PHP, Bash, JSON, YAML, Markdown, HTML, CSS, C, C++, and SQL. BUILT FOR iPHONE AND iPAD • Native SwiftUI, designed for iOS 17 and later. • Full iPad support including Split View and Slide Over. Requirements: an SSH-accessible server with Git. The built-in terminal requires tmux or GNU screen on the server.

For developers who run Claude Code or Codex in Docker Sandbox, Sandbox Relay is the phone client for driving that agent. It is a companion, not a standalone app: it needs a broker you run, with an agent connected behind it. Kick off a task from the train, check on a long-running job from the couch, or steer the agent while you are away from your desk. Docker Sandbox runs each agent in its own isolated micro VM. A small broker you self-host sits in the middle: you send work from your phone, the broker passes it to the agent, and the streamed reply comes back. Your infrastructure, your agent. The app is just the remote. New to this setup? The app's support page explains how it works and what you need to run it. WHAT YOU CAN DO - Connect to your broker with a URL and a bearer token. Connections use HTTPS, with plain HTTP allowed only for local-network addresses. - See every connected agent at a glance, with live online/offline status. - Send the agent work and watch its reply stream in token by token. Stop a turn mid-stream, or start a fresh thread whenever you want. - When an agent goes offline, its thread stays readable as history. - See per-turn input and output token counts when the broker reports them. - Save reusable prompts as local notes, organised by hierarchical tags like #work/project/feature. Drill down by tag, copy a note straight into a thread, or link a note to the thread it came from. Notes live on your device only; they never touch the broker. WHAT YOU NEED - A broker you run, reachable from your phone (over your local network, or remotely through a tunnel or private network you control). - A coding agent, Claude Code or Codex, running in Docker Sandbox and connected to that broker. PRIVACY Sandbox Relay talks only to the broker you configure. Your access token is stored securely on your device and sent only to that broker, to authenticate you; it never goes to the developer or any third party. Your notes stay on your device and are never sent anywhere. No third-party analytics, no account to create. Note that the app streams whatever your agent outputs, verbatim.
