24 alternatives to Experimental Support for Kotlin in Pulumi

Hello everyone :) Recently, my team (at VirtusLab) released an experimental support for Kotlin in Pulumi. This means you can use a convenient DSL to deploy stuff to your cloud (see examples in the repository). Getting started guide should be enough for you to use this in a toy project :). This is a proof of concept, so we would really love to hear your feedback before moving on. Please have a look at the "Giving feedback" section of the README.md.

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Experimental Support for Kotlin in Pulumi launched in 2023; newer entries below may have overtaken it.

   Run globally distributed full-stack apps on high-performance MicroVMs▲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 Lua▲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…

   Kotlin/Elm/Electron Tech Demo▲7

   Another HN Desktop client: https://github.com/spennihana/HackerDesktop Last weekend user westoncb posted[1] an app built in kotlin/swing[2]. A comment there mentioned that an electron app might be an interesting alternative, and here is the result of this last week's hackings. It uses the firebase API underneath and elm/electron to interact with kotlin via the spark-kotlin micro rest framework. The icns were made with Adobe Illustrator. The dmg unpacks to a whopping 250MB (since it packages the JRE in addition to all of the usual electron junk). video link:…

   Platform that lets you generate source code of end to end apps▲6

   Hi HN, My name is Ravi Sojitra and i'm working on a Dev Tool product named DhiWise, that let you generate production ready source code(For Node.js,Laravel,Flutter,Kotlin,Swift) in few mins with ready to get synced in your GitHub/GitLab or Download. Let me explain like you're five. Imagine you want to bake a cake and you have all the raw materials you need such as flour, baking powder, eggs. Now, you give us those materials and we will bake you the ready-to-serve cake of your choice. With this product's context, with just minimal technology specific inputs, this builder is going to…

   Mosaic – A Kotlin framework for cleaner back end code▲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. GitHub: https://github.com/Nick-Abbott/Mosaic Maven Central: org.buildmosaic:mosaic-core:0.2.0

   Built a visual UI editor that exports to code▲6

   I've been specializing in UI for over a decade. Using code for UI is great but I always wished there was a more visual code to build apps and sites. So I went ahead and built it. Decided to build it with Compose Multiplatform since I work a lot with Kotlin. Currently exports to CMP as it was simpler due to the context switch. You can try it for free and export some apps

   G# –> a new dotnet language like Go/Swift/Kotlin with C# interop▲9

   I started working on this back in 2019, mostly as a design idea. Over the last month I made a big push to make it 100% usable and replace C# in all my personal projects. I now feel it's solid enough to gather feedback from other developers. If you take it for a spin, I hope you enjoy it and send your thoughts!

    KMPShip▲15

    Hey HN, I'm an indie developer who has been building mobile apps for a while. After repeating the same setup across projects (auth, CI/CD, payments, notifications), I built a boilerplate to save time and focus on actual features. KMPShip is a Kotlin/Compose Multiplatform boilerplate that helps you build Android and iOS apps from a single shared codebase. It includes: Shared codebase (for UI, domain and data layers), Firebase Auth, Google/Apple sign-in, In-App purchases & subscriptions, local & push notifications, CI/CD setup, full documentation and a small community space…

    I made StarDesk, P2P low latency remote desktop built for game and work▲6

    Hi HN, I’m one of the devs behind StarDesk, a P2P-first remote desktop we’ve been building for ~1 year. We started this partly out of frustration: some popular RDP tools haven’t seen meaningful updates in a long time, and long-standing issues are often left unaddressed. As devs, we really dislike software that stagnates once it “works well enough”. StarDesk is our attempt to do it differently. What we focus on: -P2P by default (relay as fallback) -Low RTT + low jitter > chasing max bitrate -Encoder / input path tuned for real-time interaction -Modern E2EE (TLS/DTLS) UX-wise, setup…

    KAppMaker▲16

    Hey HN, I built KAppMaker, a Kotlin Multiplatform boilerplate that helps you launch iOS and Android apps quickly. I know the boilerplate space is pretty saturated, but after publishing two open-source Kotlin Multiplatform libraries (KMPNotifier and KMPAuth), and seeing how much manual work goes into app setup, I realized something had to change. Each time I started a new app, I spent at least 4-5 days just setting up basics like authentication, notifications, and in-app purchases—before even getting to the core feature. To speed up this process, I created KAppMaker, a boilerplate that…

    Hello HN, I’m excited to share something we’ve been working on: Cloud Troubleshooting Labs. This tool provides on-demand environments for engineers to practice hands-on troubleshooting with AWS, GCP, Azure, and Kubernetes. What it does: We use Pulumi to spin up these environments. Each scenario includes a diagram and an explanation of the available IT infrastructure. Engineers are tasked with fixing configuration issues to make the application work. Depending on the test type, the environment could range from a simple terminal to a full cloud environment or a web-based VSCode. Many of our…

    I made a simple but powerful deployment tool▲5

    Been using it for about a year now in production, but rewrote it completely in golang. My first go project so far. I wanted to have something that would make my life easier. A lot of tools nowaday kinda push you towards functional deployments and that usually doesn't work for me since I like stuff like LiveView by Phoenix and Websocket stuff in general. Old vercel deployments back when they allowed to deploy docker containers was a godsend, but since they don't offer that anymore I had to use services like fly.io(which is amazing) or heroku. However I wanted something selfhosted that I could…

    Building a Cloud Native Kubernetes Java Client▲6

    Started this because configuring Fabric8 for EKS was driving me crazy. Building a client that auto-detects your environment (IAM roles, profiles, local configs) so you don't have to wire it all up manually. Still pretty early and building for EKS right now. Long way to go, but putting it out there early to see if others have hit the same problems or want to help shape where this goes.
