Personal Mac apps, forged on demand.

Ironsmith lives in your menu bar. Describe what you need, and it builds a native Mac app for whatever you'd like. Free and open source.

Several generated Mac apps with the Ironsmith menu bar popover open in front.

Designed for local AI

Ironsmith was built from the ground up with local AI models in mind. Connect Ollama or an OpenAI-compatible endpoint to make simple apps privately and entirely on device. Or bring your own API key and create more complex ones with ChatGPT, Claude and Gemini.

Real native apps

Every app created with Ironsmith is coded in Swift and SwiftUI. No bloated Electron wrappers or background browsers.

Secure from the start

Created apps are sandboxed and hardened by default, ensuring they can't do any lasting damage to your Mac.

Ask for the app you wish existed.

Start with the blocker in front of you. Ironsmith is best at specific personal utilities that would be annoying to hunt down online.

"Make a utility that renames a folder of screenshots by date and window title."

"Build a tiny app that splits a PDF into one file per page."

"Build a clipboard cleaner that strips tracking parameters from copied URLs."

"Make a small CSV inspector that highlights duplicate rows and missing values."
