About Punter.js
Punter.js is a compact, teaching-focused JavaScript game engine designed specifically for the browser. Created by John Doherty, the engine's primary objective is to bridge the gap between programming theory and tangible, playable results in as few steps as possible. By prioritizing simplicity and immediacy, Punter.js helps students transition quickly from learning core concepts to building games they can share with others.
Built with an intentionally small API footprint, Punter.js minimizes the learning curve so users can start building right away. The platform requires nothing to install and features no build steps. Students can simply pick a pre-existing game, play it directly, edit the underlying JavaScript code, and observe their changes instantly in real-time. Additionally, the project is fully open source and accessible via GitHub.
Pros of Punter.js
- Zero installation required and no complex build steps
- Deliberately small API designed for quick learning and fast development

- Ideal for educational environments and teaching JavaScript fundamentals
Cons of Punter.js
- Small API may limit the creation of highly complex or advanced games
- Geared primarily toward teaching rather than enterprise-grade game development
- Limited information available regarding extensive third-party integrations

About SpaceSim
SpaceSim is a free, browser-based universe simulator designed for space exploration and education. Created by Romain Simon, the platform allows users to instantly journey through the cosmos without the need for any signup or account creation.
With SpaceSim, users can travel through a real-time, UTC-driven 3D Solar System and inspect source-linked scientific state data. The simulator also features the ability to observe Earth from a pinned NASA ISS trajectory, build procedural stars, visit compact objects, and collect virtual postcards of your discoveries.
To ensure transparency and educational accuracy, SpaceSim clearly labels all of its content as scientific, reconstructed, representative, procedural, experimental, or promotional.
Pros of SpaceSim
- Completely free to use with no signup or registration required
- Runs directly in your web browser with no installation needed
- Provides a UTC-driven 3D Solar System with source-linked scientific data
- Clearly labels content categories (such as scientific, procedural, or experimental)
Cons of SpaceSim
- Requires an active internet connection to run the browser-based simulation
- Features and exploration scale are limited to the simulator's built-in digital environment
