We compiled reactive JavaScript into a cartridge. The same Vue component now runs on a 2KB RAM NES and a Game Boy Advance. No JavaScript engine. No GC. The computed values and UI effects are compiled directly into bare-metal C. This is Pocket Vapor. ⚡️

This is it, native PCVR on MacOS! The OpenXR SDK can be compiled on MacOS, So I implemented a runtime and a streaming app. Godot supports OpenXR on MacOS so I use it to test my integration. Unity could work too and of course native C++. 1/x

Rive Mirror app we've been working on. Lets you view your editor file in realtime running on device. It's not just a preview, the device is running the real shippable product with the Rive Runtime.

What if you could build a fully native iOS app… using only PHP? Checkout this first demo of the new Super Native architecture behind NativePHP on iOS — where PHP runs directly alongside native code with no WebView, no JavaScript bridge, and no hybrid layer.

Introducing proof of concept React Imgui! The name is a joke, but it is accurate enough. In the last few days I have been working on a prototype of React driving Dear ImGui using Static Hermes. The result is a fully native app written almost entirely in JavaScript, using unmodified React, typed JS, plus a very small amount of glue C++ code and unmodified Dear ImGui and Sokol. The actual renderer translating React into Dear ImGui is written entirely in typed JS using zero-cost FFI. Of course this wouldn't be possible without React's great design and flexibility. I find it really fascinating that I was able to take literally unmodified React, write a little extra JS, and get a functional fully native app so quickly. Of course everything is unoptimized, and prototype code quality, and who knows how buggy, but it seems to work well enough. Please, watch the video to see it in action. If there is interest, I will write a more detailed article.

Star Fox 64, running natively on iPhone and iPad. Native ARM64 app. Metal rendering. 2x internal resolution and MSAA in settings. Touch controls. Controller support. Running on real hardware. Not an emulator, and not streaming from a Mac. HarbourMasters built Starship, the native source port. I built StarshipPad on top: the iOS/iPadOS layer, Files import, on-device setup, and mobile lifecycle. The surprise is iPhone: it doesn’t feel like a compromise. It feels like a real way to play. I used Codex 5.6 Sol to do the iOS integration work. Source, build guide, and ROM-free IPA below.

I got an MD test cart for Earthion and recorded a quick video. We’re currently testing several different carts. This cart is for the Spanish-exclusive version. Because Earthion uses a large ROM and a custom cartridge design, testing still needs a bit more time. In the meantime, enjoy seeing it running on a real MD! Stay tuned!

The new version of React Native Bottom Tabs is out! 🎉 A new highly anticipated feature: Custom JavaScript Tabs! ✨ Provide your custom tab bar while leveraging native navigation underneath 🚀 Here is a demo of it in the 🦋 app! This demonstrates smooth screen transitions using native animations along with their custom tab bar.

The Proxy Droplet produces a TON of vapor due to its ability to fully milk up, as demonstrated by . The part that you cant see is the quality of that vapor. Consistency in experience is the true difference.

herdr isn't an app. that's by design. it's a runtime for your coding agents. it owns your terminals, your agents, their state, and lets you drive them from anywhere. that was the idea from day one. but people started running with it faster than we could give them a real way to. even without any official support, they're already building on top of it. web, ios, dashboards. their own idea of what a client even is. so here's a sneak peek 👇 it's native api support in the runtime, the thing we've been building so you can. the tui will always be the first citizen. but soon you'll be able to build your own client on top of herdr, on the same protocol we do.

Super Smash Bros. 64, running natively on iOS and iPadOS for the first time. Not an emulator. BrawlerPad is built on BattleShip, which already supplied the SSB64 source-port core, Apple Metal path, and SDL controller/audio stack. BattleShip ran on Apple Silicon macOS and Android. There had never been a public iOS or iPadOS port. Now there is. The game logic is compiled into a native ARM64 app and runs through BattleShip/libultraship’s Metal/Fast3D path. No N64 hardware is simulated, and no ROM is interpreted at runtime. Smash deserves a controller, so BrawlerPad supports physical controllers through the same input path as the game. Touch works too. I used Codex 5.6 Sol on the iOS integration. Full build guide and source below.

So this game is real now, fully built with GPT-5.5. I told Codex to use the imagegen skill to generate a reference UI and sprites, and used the Build macOS Apps plugin to build the app for a native retro fantasy labyrinth game! Adjusted the UI in a few prompts and here we are!

Back from spring break with show and tell! Here is our Showcase app demoing #SwiftUI components on Android. First transpiled... and then COMPILED Swift & SwiftUI. A lot of SwiftUI support to fill in on the compiled side, but the skeleton - navigation, layout, etc - is alive!

I’m working on a new video about performance in Expo apps — and I’ve got to say, by far the most impressive technique I’ve found is digging into React Native Worklets (from Software Mansion). Realizing you can offload heavy computations into a custom runtime to keep your JS thread free and your app responsive just blew my mind. It feels like you can generate CPU power out of nowhere 😅 Stay tuned!

I used Codex 5.6 Sol to get RollerCoaster Tycoon 2 running natively on iPad. This is built on OpenRCT2, the open-source engine their team has poured years into. I compiled it to a native ARM64 iPad app and built the touch controls on top. No emulator, no x86, no streaming from a Mac. Coaster building, scenarios, and park management all work by touch. First time I've seen RCT2 run natively on iPad. Open sourcing it all below.
