the shadows that power your success

In the maker’s words, at launch

My mobile app experience with Kotlin was overwhelming and slow, so I decided to build something better from scratch. The result? An IDE written from the ground up for mobile developers who want something faster, leaner, and more focused. It's not a wrapper, plugin collection, or fork — it's built specifically to…

  Skip – Build native iOS and Android apps from a single Swift codebase2024 · skip.tools · ▲322

  Hello Hacker News. I'm Marc, one half of the team that created skip.tools. Skip is a tool that transpiles your SwiftUI iOS app into a Kotlin Jetpack Compose app, and enables you to use a single language to create a complete app that reaches the entire mobile marketplace. What it is: Skip stands in contrast to other cross-platform development tools like Flutter, React Native, and Xamarin, in that it enables the creation of genuinely native applications for both of the dominant mobile platforms. It doesn't embed a separate engine or runtime into your app, but instead lets you use pure Swift…

  Gradle plugin for faster Java compiles2025 · github.com · ▲38

  Hey HN, We've written a pretty cool Gradle plugin I wanted to share. It turns out if you native-image the Java and Kotlin compilers, you can experience a serious gain, especially for "smaller" projects (under 10,000 classes). By compiling the compiler with native image, JIT warmup normally experienced by Gradle/Maven et al is skipped. Startup time is extremely fast, since native image seals the heap into the binary itself. The native version of javac produces identical outputs from inputs. It's the same exact code, just AOT-compiled, translated to machine code, and pre-optimized by…

  Run globally distributed full-stack apps on high-performance MicroVMs2023 · koyeb.com · ▲98

  Hi HN! We’re Yann, Edouard, and Bastien from Koyeb (https://www.koyeb.com/). We’re building a platform to let you deploy full-stack apps on high-performance hardware around the world, with zero configuration. We provide a “global serverless feeling”, without the hassle of re-writing all your apps or managing k8s complexity [1]. We built Scaleway, a cloud service provider where we designed ARM servers and provided them as cloud servers. During our time there, we saw customers struggle with the same issues while trying to deploy full-stack applications and APIs resiliently. As…

  Tiny – A 2D Game Engine in Kotlin Working with Lua2023 · minigdx.github.io · ▲100

  I created a small 2D game engine named Tiny. The engine was created using Kotlin Multiplatform and can run on a JVM and JS. Funny things: Games can be created using the programming language Lua. Tiny is designed to help you create and test your ideas quickly and effectively. Not only can you run your games on your desktop computer, but you can also export them for the web, making it easy to share your creations with others. You can create games easily with the hot reload, small API and Lua, which is very easy to learn. If you want to test a game idea, to try to create your first game or just…

  Mosaic – A Kotlin framework for cleaner back end code2025 · github.com · ▲25

  Backend APIs often grow into large orchestration classes full of duplicated calls and manual concurrency. I’ve been working on Mosaic, a Kotlin framework that composes responses out of small, request-scoped “tiles.” Each tile runs once per request, dependencies resolve automatically, and independent tiles execute in parallel without boilerplate. It’s still early (v0.2.0), but working today for caching, concurrency, and testability. Curious to hear feedback on the approach.

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Trickle - Magic Canvas ▲1,064

  Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  Ten years of running every day, visualized▲958

  Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

  Draw a fish and watch it swim with the others▲935

  Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

  Use Their ID – Use your local UK MP’s ID for the Online Safety Act▲862

  Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
