Tramway SDK – An unholy union between Half-Life and Morrowind engines
Hello everyone, I would like to see if there is any interest in this little project that I have been working on for the past few years. Could be relevant, seeing the direction in which the mainstream game engines are going. I didn't really like any of the already existing options, so I tried to make my own and it turned out to be easier than expected. It's sort of like a low-budget Unreal/Source, but with open-world streaming support and it is free and open source. Very old-school. But optimized for more modern hardware. Very fast too. Still not production ready, but it seems like it is…
Tramway SDK – An unholy union between Half-Life and Morrowind engines launched on January 7, 2025 with 660 votes, #17 of 6,141 launches that month and more than 99% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Tramway SDK is a free, open-source game engine inspired by classic titles like Half-Life and Morrowind. It features open-world streaming support and is optimized for modern hardware while maintaining old-school design principles. Built as an alternative to mainstream engines, it prioritizes performance and efficiency. The creator is still testing it on larger projects before considering it production-ready, though core functionality is largely operational.

Tramway SDK (heavy metal spelling – T̈ra̦m̊ẅa̦ÿ SD̈K) is a graphics package/framework/game engine that I have been working on for the past 3 years. In this article I attempt to turn you against mainstream engines and I will explain, in detail, why Tramway SDK is not as awful as them. Unity needs very powerful hardware and consumes enough power to burn down a rainforest. Godot is slightly better, but you still need relatively capable hardware. But what if all that you really want to make is just a lowpoly horror roguelite deckbuilder simulator? 15 year old hardware is more than capable of running a game like that, but not if you use a mainstream…from racenis.github.io

Breakout with a roguelite/vampire survivor twist2025 · breakout.lecaro.me · ▲412Hi HN ! This is an open source project I've been working on for a while. It's actually the third breakout-like game I've built. I really like the simplicity of the concept, having just one input (the puck horizontal position) and a simple gameplay that gives a low skill floor. My girlfriend and I played a lot of the excellent LBreakoutHD, an open source breakout game that follows the traditional formula of having multiple lives, scoring points by breaking bricks and catching the good upgrades that spawn randomly and fall down, while avoiding bad upgrades. She liked this game because it is…
- ULUnity like game editor running in pure WASM2023 · raverie-us.github.io · ▲644
In the wake of all the Unity nonsense, just wanted to toss the Raverie engine into this mix :) We’re building off a previous engine that we worked on for DigiPen Institute of Technology called the Zero Engine with a similar component based design architecture to Unity. Our engine had a unique feature called Spaces: separate worlds/levels that you can instantiate and run at the same time, which became super useful for creating UI overlays using only game objects, running multiple simulations, etc. The lighting and rendering engine is scriptable, and the default deferred rendering…

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…

- TITetris in a PDF▲1,289
I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
