We make the kind of libraries we wish already existed — radial layouts, zoom-driven UIs, pixel-perfect DOM capture.
Zumerlab is an independent software studio. We work in the open: every primitive ships with source, docs, and a live demo. No frameworks of frameworks, no vendor lock-in.
Below: the active specimens. Each is in production use, MIT-licensed, and maintained.
Most of what the web platform can do is still under-explored. There are angles, depths, and capture surfaces that designers reach for every week and re-implement from scratch.
Zumerlab focuses on those gaps. Small, sharp tools that ship with no transitive dependencies and a permissive license.
A CSS framework for building radial interfaces — gauges, donuts, knobs, pie menus, dashboards — using only CSS. No layout JavaScript.
Drop in two files. Works with plain HTML and any framework (React, Vue, Svelte). Angles, radii, and positions are computed in stylesheets.
Hierarchical zoom navigation: you move in Z (depth) through discrete views laid out in the XY plane. Spatial transitions instead of flat screen swaps.
Pluggable transition drivers (CSS, WAAPI, Anime.js, GSAP, Motion). Plugin API, hash router, prefetch cache. UI-agnostic.
Captures any HTML element as a scalable SVG image — preserving styles, fonts, background images, pseudo-elements, and shadow DOM.
Exports to SVG, PNG, JPG, WebP, canvas, or Blob. Supports same-origin iframes, CSS counters, line-clamp. Zero dependencies.
