FreeMilk vs. Cursor: An AI Code Editor on a Mac or a Free Agent on Your iPhone?
Cursor is a superb AI code editor, but iOS work with it still needs a Mac and Xcode, while FreeMilk runs the whole native Swift loop from your iPhone, free.
Cursor is probably the most loved AI coding tool among professional developers: a full editor where an agent reads your codebase, writes real diffs and keeps you in control. Comparing it to FreeMilk is really a comparison of two workflows: editing source in an IDE at a desk, or steering a running app from your phone. For iOS, and for anyone who doesn't want another subscription, the gap is wider than it looks.
The short answer.
Cursor is a desktop code editor with a free tier and paid plans for heavy use. Building and running iOS apps with it still needs a Mac with Xcode. FreeMilk is a free iPhone app: its agent writes the code, remote Macs compile Swift projects with Apple's toolchain, and a live simulator streams to your phone. It also builds websites and backends.
At a glance.
| Compared | FreeMilk | Cursor |
|---|---|---|
| Where you build | An app on your iPhone | A desktop code editor |
| Building iOS apps | Remote Macs, simulator streamed to your phone | Needs your own Mac with Xcode |
| What you look at | The running app, plus the files | Code and diffs |
| Your code | Files on your phone, readable and editable; Swift exports to Xcode | Local Git checkouts |
| Models | Free daily allowance, or your ChatGPT subscription | Free tier, paid plans for heavy use |
| Price | Free, ad-supported | Paid plans for regular use |
What Cursor assumes.
Cursor edits code; it doesn't replace the iOS toolchain. To build and run what it writes for iPhone, you still need a Mac, Xcode, simulators and signing, plus the judgment to review Swift diffs. For professional engineers who already live in that setup, Cursor is a genuine accelerant. For everyone else, the Mac-shaped prerequisite is the whole barrier to entry, untouched.
What FreeMilk changes.
- It's free. Ads fund a daily allowance of coding models, covering GLM, ChatGPT and DeepSeek, that refills every day. Already pay for ChatGPT? Connect it and use your plan.
- No Mac anywhere in your setup. FreeMilk builds Swift projects on remote Macs and streams the live simulator to your phone.
- The interface is the running app, not the diff. You tap through real screens in the live simulator and describe what should change in plain words.
- The agent lives in your Dynamic Island. It shows exactly what it's doing, so a build in progress is a glance away, not a terminal you babysit.
- More than iOS. Websites, backends in JavaScript or Python, and mobile games run in built-in execution environments.
- No lock-in. Swift projects export as a complete Xcode project, the same kind of codebase a Cursor-and-Xcode workflow produces, not a proprietary format.
Cursor makes professional developers faster at a desk. FreeMilk makes building possible everywhere else, for free, including for people who were never going to buy a Mac to find out whether their idea works.
What does it cost?
Cursor has a free tier, and regular use of its agent means a paid plan. FreeMilk is free: ads pay for a daily model allowance, and you can connect your own ChatGPT subscription to use your plan. You can compare yearly costs across popular tools in the cost chart on our homepage. Publishing an iPhone app to the App Store still requires an Apple Developer Program membership.
Which should you choose?
If you're an engineer with a Mac who wants line-level control over a large codebase, Cursor is built for you. If you want to go from idea to a native app, a website or a working backend on your phone, today, from your couch, without a subscription, FreeMilk collapses the toolchain into the device you already own. Plenty of people will use both: FreeMilk to take an app from zero to real, and an IDE later if the project grows a team around it.
Frequently asked questions.
Can Cursor build iOS apps on its own?
Cursor writes and edits code, but building and running iOS apps still requires a Mac with Xcode. FreeMilk handles the build on a remote Mac and streams the simulator to your phone, so no Mac is needed.
Do I lose the code if I start with FreeMilk?
No. FreeMilk writes real source files: Swift and SwiftUI for iPhone apps, and HTML, CSS, JavaScript or Python for the web. Swift projects export as a complete Xcode project, the same kind of codebase you could later open and evolve in a traditional IDE workflow.
Do I need to know how to code to use FreeMilk?
No. Describe what you want the way you'd explain it to a friend, then react to the running app. If you do code, every file is yours to read and change.
Is FreeMilk really free?
Yes. FreeMilk is supported by ads, which pay for a daily allowance of coding models. There's no subscription and no per-token bill.
