tldiagram vs AirShell

Software system-architecture diagramming app that helps engineering teams design, debug, and communicate complex distributed systems. tldiagram makes it easy to create nested views of a complex system with higher detail as you go deeper that can be zoomed in and out to give you the context you need without the noise.

AirShell is a mobile SSH terminal for developers who live in the command line. Connect to your Mac, Linux server, VPS or dev box from iPhone and keep working in the same CLI-first environment you already use on desktop. AirShell is designed for AI coding tools, tmux workflows, remote shells and repeatable terminal actions. Key features: - Live SSH terminal built for focused mobile work - Saved connection profiles with Keychain-backed secrets - OpenSSH ED25519 and RSA private key support - Trusted host-key verification on device - Press-and-hold speech input for terminal commands and prompts - Custom command shortcuts for deploys, logs, tests and tmux actions - Quick entries for Codex, Claude Code, Gemini CLI and CodeBuddy - CLI completion notifications when supported tools return to the shell prompt - tmux window and directory workflows for long-running sessions - iCloud sync for server profiles and custom commands AirShell does not replace your paid CLI tools. It extends them. Use the subscriptions, servers and command-line workflows you already have, even when you are away from the computer. Ideal for: - Checking long-running AI coding agents - Sending quick follow-up prompts by voice - Restarting services or tailing logs from anywhere - Keeping SSH and tmux workflows available from your pocket - Making desktop-grade CLI tools useful beyond the desk Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
