WebGL Game Development

Browser-based games that run everywhere - no plugins, no installs

Why WebGL?

WebGL enables rich gaming experiences directly in the browser without plugins or app installs. For educational clients, this is particularly valuable - games run on school Chromebooks, tablets, and locked-down networks where installing applications is impossible.

Our team has shipped WebGL and HTML5 titles for the Museum of London, EU Horizon 2020 research programmes, and educational publishers. We understand the unique constraints of browser-based deployment: memory limits, loading performance, and cross-browser compatibility.

What We Build With WebGL

Unity WebGL Builds

Compile Unity projects for browser deployment with careful memory management, asset bundle streaming, and loading optimisation for fast first-paint times.

HTML5 Canvas Games

Lightweight 2D games using HTML5, TypeScript, and frameworks like Phaser for maximum compatibility on low-powered devices and locked-down networks.

Flash-to-WebGL Migration

Rescue legacy Flash content for modern browsers. We reverse-engineered the Great Fire of London without source code and rebuilt it in HTML5.

Educational Web Games

GDPR and COPPA compliant browser games for schools and institutions. No app installs required - works on Chromebooks, tablets, and classroom PCs.

Cross-Browser Compatibility

Single codebase deploying to Chrome, Safari, Firefox, Edge, and embedded webviews. Rigorous testing across desktop and mobile browser environments.

WebGL Performance Optimisation

WebGL-specific profiling including texture compression, draw call reduction, memory budgeting, and shader optimisation for low-spec hardware.

Frequently Asked Questions

Yes. Unity supports WebGL as a build target, compiling your game to run directly in modern browsers without plugins or installs. We have shipped multiple Unity WebGL titles for educational clients, including games deployed on school Chromebooks and locked-down institutional networks where installing applications is not permitted.
A typical Flash-to-HTML5 conversion ranges from £5,000 to £25,000 depending on the complexity of the original game, the availability of source code and assets, and whether any redesign work is required. We rebuilt The Great Fire of London for the Museum of London entirely from the compiled Flash output without access to the original source, which sits at the more complex end of the spectrum. Simpler conversions with available source code are considerably faster and more affordable.
WebGL games run inside the browser’s sandbox, which means they have less access to system memory and GPU resources than native applications. Texture sizes, draw calls, and total memory budget all need careful management. We address this through asset bundle streaming, texture compression, shader optimisation, and aggressive draw call batching. For most 2D and moderate-complexity 3D games, WebGL performance is more than sufficient for a smooth player experience.
WebGL is ideal for educational deployment. Games run directly in the browser with zero installation, which removes the biggest barrier in school and institutional environments where IT departments restrict software installation. WebGL games work on Chromebooks, tablets, and classroom PCs across Chrome, Safari, Firefox, and Edge. We also ensure compliance with GDPR and COPPA requirements for games used by children.
