Designed for local AI
Connect Ollama or an OpenAI-compatible endpoint to make simple apps privately and entirely on device. Or bring your own API key or ChatGPT subscription and create more complex ones with ChatGPT, Claude and Gemini.
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.
Requires macOS 26 or newer. Supports Intel and Apple Silicon Macs. Download for Intel Mac instead.
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, greatly reducing the impact of bugs, mistakes, or malicious behavior.
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."
Find a Mac app. Make it yours.
The Ironsmith Store is a community library of Mac apps built to be changed. Every app is remixable, so you can start with something that already works and shape it into exactly what you need.
Explore the StoreSearch by feature
Describe the capability or workflow you want and find apps by what they do, not only what they are called.
Remix any app
Choose the closest match as your base, then add features, remove what you do not need, or take it in a completely new direction.
Let Auto Remix find the base
Turn on Auto Remix when you describe a new app. Ironsmith searches the Store for useful foundations and reuses their capabilities automatically.
