MyApping vs PromptCodex

Describe what you want and watch it get built. MyApping turns a message in a chat into a working app, a playable game, or a running program — built for you by an AI agent, on your phone. THE GAME FEED Swipe through games people actually built here. Every card is a clip of the real game running — not a menu screenshot — and one tap plays it full screen. Share any game with a link that opens straight in a browser, no account and no install needed. BUILD PLAYABLE GAMES Describe a game and the agent builds a real one: 2D or full 3D, with characters, worlds, vehicles, weather and physics. Small games play instantly in your browser; bigger 3D worlds run natively on your phone for full frame rates. Keep a game private while you refine it, then post it to the Feed when it's ready. Every build is saved as its own version, so nothing you liked ever gets overwritten. No install. No console. No code. BUILD FULL APPS Websites, web apps and tools — with real databases and backends, not just static pages. Work in a folder on your device or in your own GitHub repo, and preview instantly in the built-in browser. For bigger jobs, hand it to a cloud agent that keeps building while you're away, opens a pull request on your repo, and sends you a live preview link when it's done. HTML, CSS, JavaScript, React, Vue and more. BUILD WITH OTHER PEOPLE Turn a channel into a shared room. Invite friends by username and everyone builds into the same project. Mention @gogi to put the agent to work, or mention each other to talk it through first. When a build starts, everyone in the room can watch it run and open the result — not just the person who asked. RUN CODE IN ANY OF EIGHT LANGUAGES Write and execute Python, JavaScript, Ruby, Go, Rust, C, C++ and Java right from your phone, with full stdout and stderr. Python charts render inline as images. GENERATE IMAGES Create images from a description — portraits, landscapes, concept art — or let the agent generate artwork and drop it straight into the app it's building for you. CONNECT YOUR TOOLS • GitHub — browse repos, create and edit files, open pull requests • Files — work directly in a folder on your device or in iCloud • MCP servers — connect any MCP-compatible service, and its tools become the agent's tools CHANNELS AND NOTIFICATIONS Organize work into channels — one per project, topic or workflow — and mute the ones you're not watching. Cloud builds can take a while, so you get a notification the moment yours is ready, even if you've closed the app. FREE AND PRO Free includes chat, code execution, browser-playable games and five cloud builds a day. Pro removes the daily limit and unlocks full-detail game worlds, image generation, MCP servers and the most capable Gogi model.
