Flax - an early HTML5 game engine from 2010
Flax is an early HTML5 game engine created by Ciarán McCann and Carl Lange, launched in 2010. It allows developers to build games using HTML5 technology during the era when browser-based game development was emerging.… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

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…

Hey HN, I'm Ron Efroni, CEO at Flox, and today we are releasing version 1.0 of our open source CLI, helping folks manage development environments everywhere.My own experience with development environments began with air-gapped systems, having to actually burn software to a CD to iterate over a very slow and expensive development cycle, sometimes reaching the server rack and realizing I have the wrong disk.... Fast forward to today and there are countless alternatives available backed by incredible compute resources, yet we somehow still find ourselves paying the price of long development…

For the last 5 years I've been working on a layout engine that targets CSS2 and some more modern properties. Live demo: https://chearon.github.io/dropflow/ It matches browsers in all cases I can find where they agree, and it's fast. It supports `position`, `inline-block`, `z-index`, and complex properties like `float` and `vertical-align`. It doesn't support high-level layout like flexbox or grid yet, but you can get intrinsics to easily divide space yourself and paint multiple layout trees. It has a great text layout implementation, and supporting non-Latin scripts is a…

Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

We’ve been working on Vaev, a minimal web browser engine built from scratch. It supports HTML/XHTML, the CSS cascade, @page rules for pagination, and print-to-PDF rendering. It even handles calc(), var(), and percentage units—and yes, it renders Google.com (mostly). This is an experimental project focused on learning and exploration. Networking is basic (http:// and file:// only), and grid layouts aren’t supported yet, but we’re making progress fast. We’d love your thoughts and feedback.

Hi HN! Korean high school senior here, about to start CS in college. I built a browser engine from scratch in C++ to understand how browsers work. First time using C++, 8 weeks of development, lots of debugging—but it works! Features: - HTML parsing with error correction - CSS cascade and inheritance - Block/inline layout engine - Async image loading + caching - Link navigation + history Hardest parts: - String parsing(html, css) - Rendering - Image Caching & Layout Reflowing What I learned (beyond code): - Systematic debugging is crucial - Ship with known bugs rather than chase…

Hello HN, Just wanted to show this little 2D game engine that I've been working on for some time (around 2 years on the editor part, longer on some of the components). It's quite full featured but obviously this a project of such magnitude already that the work never really ends. That being said it's definitely already at a point where games can made and published. The editor runs natively on Windows and Linux using Qt5. The games can run on both Win and Linux as well as on WASM with WebGL. Feature wise there's a bunch of the stuff you'd expect. Audio, graphics, scripting,…
