All Hands on Deck

Everyone sees the group photo before it's taken.

All Hands on Deck is an iOS-first group photo app with a live shared viewfinder. One person sets up their iPhone as the camera; everyone else sees the frame in real time on their own devices — natively on iOS/watchOS or in any browser, with no installation required.

Built and maintained by LeopardCode.AI.

The Experiment

This app was built end-to-end through agentic coding with Claude Code — describing intent, reviewing AI-generated implementations, and steering iteration by iteration. No Swift, TypeScript, or SQL was written by hand.

The hypothesis: can a solo developer with an idea, a capable AI coding agent, and zero infrastructure budget ship a real, multi-platform product — iOS, watchOS, and web — without a team?

Stack — 100% free and open source:

Layer	Technology	Cost
iOS + Watch App	SwiftUI, Multipeer Connectivity, Vision	$0
Web Viewer	Vite, React, TypeScript	$0
Project Config	XcodeGen	$0
Realtime Backend	Supabase (free tier)	$0
Web Hosting	Vercel (free tier)	$0
CI/CD	GitHub Actions	$0
AI Coding Agent	Claude Code	—

The result: a fully functional group-photo app with live viewfinder streaming, AI-powered best-shot burst capture, face-in-frame detection, Apple Watch remote control, universal links, reactions, install-free web viewers, and a complete test suite — without a backend bill.

Key Features

• Live shared viewfinder — every participant sees the camera frame in real time
• AI best-shot capture — burst capture with Vision-based selection of the best frame
• Face-in-frame detection — confirms everyone is visible before the shot
• Apple Watch remote — trigger and monitor the session from the wrist
• Install-free web viewers — join via universal link in any browser
• Reactions — real-time feedback from viewers to the photographer

Quick Start

# iOS
xcodegen generate
xcodebuild -project AllHandsOnDeck.xcodeproj -scheme AllHandsOnDeck \
  -destination 'platform=iOS Simulator,name=iPhone 17 Pro Max' build

# Webapp
cd webapp && npm ci && npm run dev

# Server (optional)
cd server && npm ci && npm run dev

Architecture

Tech stack: SwiftUI, Multipeer Connectivity, Vision, Supabase (Postgres + Realtime Broadcast), Vite/React, WebSocket relay.

Streaming (since 2026-06): Live preview frames travel over Supabase Realtime Broadcast (ephemeral pub/sub, no database writes). The events table carries only low-volume control messages, kept clean by a pg_cron job. The webapp is code-split — the landing page loads ~78 kB gzipped instead of 148 kB.
