Glowbom turns drawings into native applications. You sketch what you want, get a working prototype, and coding agents make it production ready.
You own everything. All code lives on your machine. Cloud services are optional.
See the Quickstart for a full walkthrough with screenshots.
Glowby OSS is powered by OpenCode and works with a wide variety of agents and models. Use free models, log in with your ChatGPT account to access frontier models like GPT-5.4, bring your own API keys, or run local models with Ollama. Support for Codex App Server is planned.
You pick what works best for your project. There are many options and the quality is high across the board.
Glowby OSS is the free, open source tool that takes your project and makes it ready to ship. It runs on your computer and supports many AI providers (OpenAI, Anthropic, Google, xAI, Ollama, and more).
The repo includes a ready-to-use project template in project/ with folders for each platform:
project/apple/: iOS appproject/android/: Android appproject/web/: web appproject/prototype/: design and assetsRemove any platform folder you do not need.
