A lot of people have been asking for an explanation about how dactyl.dev works
It's actually quite a bit of magic emulating iOS in the browser. I wrote up an explanation here:
dactyl.dev/blog/how-dactyl-w…
wouldn't it be nice if Claude Code and Codex were just zsh "unknown command" fallbacks?
wouldn't need to --resume or switch foregrounds
IOS SIMULATOR IN THE BROWSER
Introducing Dactyl
Dactyl is a vibe coding platform for native iOS and native Android apps. What's interesting about it is the device simulator: we've built a SwiftUI renderer in WASM.
This means as you're developing, you get low latency in browser canvas simulation of the app to play with. Also things like oauth flows happen in the browser.
If the app uses the camera - the browser camera API allows us to display it in the simulator.
We also let you connect your ChatGPT subscription so you don't have to buy tokens through us (+ markup)
Through [magic] - we can run the same SwiftUI code the agent writes for iOS in android, with native components.
This is the work of @undefined_void (primarily), @piscisaureus, myself, and others at Deno.
It's built on Durable Objects perhaps unsurprisingly
dactyl.dev/
fun fact: Deno for macOS is built with a custom lazy linker called "lzld"
It improves startup time by a couple ~μs by deferring Apple framework initialization (weak linking)

A remapper for VIA keyboards built with gpui
Made with my bare hands on the weekend
I need to do more no-AI side projects to feel motivated, software engineering is souless af these days
After months of iterations, its time to reveal it:
dactyl.dev emulates iOS and Apple frameworks entirely in your browser. On top of that it lets you:
- ship to iOS, iPad and Android without a Mac
- built-in storage, authentication and realtime cloud for your apps
- connect your own ChatGPT if you want
On top of the emulator, we've also built a native component engine that also lets us ship Apple apps to Android
Try it out!
