Mobile IDE vs Harness Code

Mobile IDE – build working apps from a prompt, a sketch or your voice Describe an idea in plain words and Mobile IDE builds a real multi-file web app (HTML, CSS and JavaScript) that runs instantly in a live preview right on your iPhone. No laptop, no setup, no account. LIVE PREVIEW Every project runs on your device in a built-in preview and keeps working offline once it is built. Tap through your app, test it and open it full screen. REAL PROJECTS, NOT SNIPPETS Each project has its own files and a file tree. Read the code with syntax highlighting, copy it, or edit any file by hand in the Code tab. ITERATE IN PLAIN WORDS Ask for a change like "Make the buttons blue and add dark mode". The AI agent updates only the files that need it and shows exactly what changed, with added and removed lines for every file. UNDO AND VERSION HISTORY Every change is saved as a new version. Undo in one tap, compare versions line by line and restore any earlier one. Nothing is ever lost. SKETCH TO APP Take a photo of a hand-drawn sketch or pick a screenshot of any screen, and Mobile IDE turns it into a working interface. VOICE PROMPTS Say what the app should do and watch the live transcript turn into a new app or a change request. EXPORT AND SHARE Save your project as a ZIP to the Files app or send it to your Mac with AirDrop, then keep working in your favorite editor. START FROM A TEMPLATE Habit tracker, landing page, portfolio site, quiz game, snake game, or anything else you can describe. PERFECT FOR • Indie makers and founders prototyping an idea • Designers turning sketches into clickable mockups • Students learning HTML, CSS and JavaScript • Developers who want to build on the go • Anyone curious about vibe coding Light and Dark appearance, haptics and a clean, focused workspace.

Harness Code turns your computer's AI coding agents into a native phone experience. Start threads with Claude Code, Codex, or the built-in Harness engine — which brings 300+ models to your fingertips through your own OpenRouter key, no CLIs required. Watch replies stream live with full markdown, review the diffs and files your agents produce, answer their questions with a tap, and get a push notification when a long task finishes — from anywhere, over your own private Tailscale network. Built for real remote control, not just notifications. There's no cloud relay to lag, disconnect, or sit between you and your agent — your phone talks straight to your own computer over your private network. Sessions live on the computer, so nothing is lost if your phone sleeps or you drive through a tunnel: reopen the app and pick up exactly where the agent is. Steer mid-task, queue follow-ups, approve or deny actions, switch models and permission modes — everything you could do at the desk, from your pocket. Your computer does the work; your phone is the remote. Harness Code connects only to the harness server you run on your own Mac or Windows PC. No accounts, no middleman, no data leaves your devices. - Three engines: Claude Code, Codex, or the built-in agent with 300+ models via OpenRouter - Multiple concurrent threads, each with its own engine, model, and working directory - Streaming replies with markdown, code blocks, and tool-activity timelines - Reasoning summaries, per-message token/cost readouts, and usage-limit tracking - Preview HTML, PDFs, images, and code your agents create - Voice dictation, image attachments, slash commands, permission modes - Approve or deny agent actions remotely — even ones triggered by scheduled automations - Archive, search, drafts, and deep-linked push notifications Requires: a Mac or Windows PC running the free harness server (60-second install from harness-site.vercel.app). Bring your own AI: the Claude Code or Codex CLI signed into your subscriptions, an OpenRouter key, or all three. Not affiliated with Anthropic or OpenAI.
