DevToolkit vs AppRelay Remote

A developer's toolkit in your pocket. SSH, SFTP, FTP/FTPS, DNS, Ping, Traceroute, HTTP, WebSocket, SSL and more — all in one app, no accounts, no data sent to the cloud. A single password encrypts everything and keeps it on your device. 13 professional tools, one interface. Native iOS 17 app; no ads, no tracking, no backend. NETWORK DIAGNOSTIC TOOLS • DNS Lookup — A, AAAA, MX, NS, TXT, CNAME records; multiple types in one query • Ping — live latency chart, avg/min/max and packet loss statistics • Traceroute — UDP-based, per-hop latency with reverse DNS • Redirect Checker — follows the HTTP redirect chain step by step; loop detection • SSL Checker — TLS certificate, chain, expiration, cipher suite, SAN list FILE TRANSFER (FTP/SFTP) • FTP, FTPS and SFTP protocol support • Folder upload and download (recursive, including subdirectories) • File permissions (chmod) — numeric mode with preview • Rename, move, copy, bulk delete • Tappable breadcrumb for fast directory navigation • Home icon jumps to the root directory in one tap • Connection details and passwords stored encrypted REMOTE SHELL (SSH) • xterm-256color emulation — top, htop, vim and other screen apps work smoothly • Password, OpenSSH Ed25519 private key, and Secure Enclave-backed P-256 key auth • TOFU host key verification; warns against MITM attacks • Customizable keyboard shortcuts: Ctrl, Esc, Tab, arrow keys, pipe, tilde, slash • Reorder shortcuts by drag and drop • Active SSH sessions stay alive in the background WEB DEVELOPMENT • Built-in browser — WKWebView with Console, Network, and Storage panels • HTTP client — GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS; header editor, JSON/Form/Raw body • WebSocket — connect, send/receive text and binary frames, live log, 500-frame buffer • History for previous requests (HTTP and WebSocket) FILE MANAGER • Local file browser with tappable breadcrumb • Syntax-highlighted code editor: JSON, YAML, Markdown, JavaScript, TypeScript, Python, Bash, HTML, CSS • Image viewer and editor — crop, resize, convert to PNG/JPG/WEBP/HEIC/GIF/ICO, quality control • PDF reader • Media player: MP4, M4V, MOV, MP3, AAC, WAV, MKV, WEBM, AVI, FLV, TS, OGG • Archives: ZIP, TAR, GZIP, BZip2, XZ, 7Z, RAR extraction; ZIP compression • Hardened against archive attacks like zip-slip MEDIA PLAYER (from URL) • MP4, MOV, MP3, M4A, AAC, WAV • HLS live streams (.m3u8) • Custom headers like Authorization and Cookie (HTTPS only) • History of loaded streams NOTES • End-to-end encrypted notes — protected by your app password • Attach photos and files • Attachments open directly in the in-app viewers SECURITY • On-device PBKDF2 (200,000 iterations, SHA-256) and AES-GCM encryption • All connections, passwords, SSH keys, notes, and history stored encrypted • Atomic password change with automatic rollback on failure • Auto-lock — immediate, 1 min, 5 min, 10 min, 30 min, 1 hour • Auto-wipe after too many wrong password attempts (optional; 3, 5, 10, 15, 20) • SSH private keys can be generated inside the Secure Enclave; the key never leaves the device • No data is sent to any cloud. No backend. No account required. WHO IS IT FOR? System administrators, backend and web developers, DevOps and network engineers, and anyone who tinkers with servers and networks. One app, one password, fully local — a professional workstation in your pocket. WHAT CAN YOU DO? • Connect to a remote server via SSH, run commands, tail logs • Transfer files and folders over SFTP, change permissions remotely • Verify DNS, SSL, and redirect chains when launching a new domain • Diagnose network issues with ping, traceroute, public/local IP • Test a REST API, try a WebSocket endpoint • Watch live console output and network traffic in the built-in browser • Download a ZIP archive, extract it, edit the code inside with syntax highlighting

Stop walking back to your desk to kick off a build. Ship from the couch. AppRelay Remote is the mobile companion to AppRelay Server for desktop — a remote control that commands your Mac or PC to build, run, test, and ship your app projects. The Mac does the work; your phone drives it. Pair once over your local Wi-Fi and your whole AppRelay workspace comes with you: every project, every lane, every release channel, right on your iPhone or iPad. WHAT YOU CAN DO • Trigger builds, runs, and test suites on your Mac with a tap • Cut a release — ship a lane to its distribution channel without touching your desk • Watch live, streaming log output as each build runs, with a Stop button when you need it • Browse every project as a card: toolchain, lanes, version, and source-control status at a glance • Edit the full project configuration — general settings, lanes, servers, toolchains, test suites — and save it back to your Mac • Bump or set version and build numbers • Edit .env / dotenv files on disk, remotely • Manage your Mac's AppRelay license: activate a key, check status, or move the seat BUILT FOR iPHONE AND iPAD On iPhone you get a fast, single-column flow. On iPad you get the same two-column sidebar-and-detail layout as the Mac app — it even re-skins live when you change the desktop theme. SECURE BY DESIGN • Discovers Macs on your network automatically over Bonjour • Pair with a one-time token shown on your Mac — each device gets its own credential • All traffic runs over TLS, pinned to your Mac on first connection • Your Mac stays in control: block or disconnect any device at any time • Secrets never leave your Mac — the phone sees credential labels only, never their values REQUIRES THE MAC APP AppRelay Remote needs AppRelay for macOS running on the same network. Get it at apprelay.io/download. Free to pair; Pro features are managed on the Mac. AppRelay Remote needs the desktop app, which is **not** on the Mac App Store — it ships directly from the website (Sparkle-updated, notarized DMG). **Download:** https://apprelay.io/download **Requirement:** macOS 13 (Ventura) or later. **Enable the server:** open AppRelay → **Relay Monitor** → **Start**. This starts a local HTTPS server, advertises it over Bonjour (`_apprelay._tcp`), and shows the address + a pairing token. **Pair:** on the same Wi-Fi, open AppRelay Remote, pick the Mac under "Discovered Macs" (or enter host/port manually), and enter the pairing token. **Security:** self-signed TLS pinned trust-on-first-use; each device gets its own token; the Mac can block/disconnect any device from Relay Monitor.
