Built a visual UI editor that exports to code
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

Once UI 1.5Dec 2025 · once-ui.com · ▲299When I started my career and built my first design system, I was beyond excited. It took a lot of iterations, learning and 6 months of work to launch it internally. In the next job, I did it again, then at the following job, again… And no matter which company I worked for, 80% of the design system was the same. I’ve decided to work full-time on the design system I’ve always wanted, and today I’m launching and open-sourcing it. You can use it to build Next.js apps faster, and I’ve designed it in a way that it’s hard to go wrong with it: you can choose any settings, and you’ll end up with a…
- GAG# –> a new dotnet language like Go/Swift/Kotlin with C# interopJun 2026 · davidobando.github.io · ▲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!
Leetcode but for front end devs (terrible idea?)2022 · vacation-call-335691.framer.app · ▲8Howdy friends! Tell me if this is an atrociously terrible idea - I've been working on building a leetcode for clientside devs so we can practice React and Javascript interview questions in a more concise way, I call it clientside.dev I just finished a beta version of it yesterday and plan on releasing it with many more problems on Jan 1st but it's there if you wanna play with it open to any ideas / feedback however mean or nice it may be :)
- WAWhat a designer can ship with GPT in 8 days2023 · testflight.apple.com · ▲12
After getting impatient with a "SwiftUI for Designers" course I decided to fuck around and find out. Just hours after asking my 1st question: "Are you familiar with SwiftUI?" the core functionality of this app (an exercise utility) was up and working. I've spent the past week tweaking the UI with small animations and features. It's a humble tool (local storage only) but I am nonetheless floored with how GPT has allowed me to completely skip the "learning syntax" part of development and ship something that I actually use. Not only did it lower the syntax bar virtually to 0... I've learned…
I built a side project to manage my side projects2024 · apps.apple.com · ▲9Hello HN! I got pretty overwhelmed with Notion, Trello, etc. (Even though they are great tools!) as an indie dev, so I built an app that is simpler to use and perfectly suited for an indie like me :) You can basically divide your projects into multiple milestones (a milestone could be e.g. a new version), and the milestones can have multiple tasks that are either todo, in progress, or done. The progress for each milestone is calculated with those tasks, and you can also prioritize and categorize the tasks using tags (E.g. for me, #ph turns into "High Priority", and #pm into "Medium…
- IBI Built a UI to finetune LLMs x100 faster2024 · finetuna-ui.com · ▲7
After fine-tuning GPT for a personal project, I realized how tedious it is to write plain text in a massive JSON file. That's why I built this app for my own use, and I want to see if others could benefit from a tool like this as well ;)

Talanoa▲346Hi 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…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
