    SwissGL

    SwissGL

    SwissGL is a minimalistic wrapper on top of WebGL2 JS API

    ...Acting as a "Swiss Army knife" for WebGL2, it simplifies shader, texture, and framebuffer management into a single, expressive interface that enables developers to write complex GPU workflows in just a few lines of code. The library centers around one main function that unifies rendering and compute operations, allowing the creation of particle systems, GPGPU effects, and real-time simulations entirely on the GPU. Despite its simplicity and small size (under 1000 lines of code), SwissGL demonstrates remarkable flexibility, from basic visual experiments to complex multi-pass rendering pipelines. It’s also designed as an exploration of minimalist graphics API design, serving as an early experimental step toward the upcoming WebGPU era.

    ...Once the layout is arranged, the tool generates the corresponding HTML and CSS you can copy into your project—thus bridging the gap between design and code. The interface supports drag-and-drop of “divs” into grid cells, and you can experiment with grid gaps, spans and layout refinements in real time. Because it removes the barrier of hand-writing complex grid-template or grid-area definitions, it’s particularly useful for designers who are less comfortable with CSS or want rapid prototyping of grid layouts.

Audio uses a real toy recording whose playback changes with motion, with a synthesized Web Audio fallback when the sample cannot be decoded. The mobile-first interface adapts to screen size, while a local counter records manual swings only in the browser. Its source is publicly visible, but the project explicitly restricts redistribution and public deployment.

    High velocity native mobile development requires us to adopt continuous integration workflows, which means our reliance on manual QA has to drop significantly. Detox tests your mobile app while it's running in a real device/simulator, interacting with it just like a real user. The most difficult part of automated testing on mobile is the tip of the testing pyramid - E2E. The core problem with E2E tests is flakiness, tests are usually not deterministic. We believe the only way to tackle flakiness head on is by moving from black box testing to gray box testing. ...
