The whole engine runs in your browser

Lakolam's generators, solvers and rasteriser compile to WebAssembly. Both studios below are static pages: your pages are generated on your machine, nothing is uploaded, and no account exists to create.

Lakolam Studio

Recommended

The shipping interface: Astro + a WASM build of the engine, with schema-driven controls, live previews, seed stepping and every export format. Light and dark, fast on any machine.

GPUI Studio

Experimental

The same engine behind a fully-Rust, GPU-rendered interface built on GPUI — the framework behind the Zed editor — compiled to one WebAssembly module: generators, rasteriser, UI, fonts and icons, three requests total.

What makes it a studio, not a toy

Every knob, from the schema

Each generator publishes a JSON Schema of its spec; the studio builds typed controls from it — dropdowns for enums, steppers for numbers, line editors for wordlists. Nothing is hard-coded, so new generators appear with full controls.

Seeds you can keep

Step the seed, reroll it deterministically, or type one in. The seed plus the spec is the page: paste the same values next year and get the same bytes.

Export at print quality

SVG master, PNG from 96 to 600 dpi, and fixed social canvases — Square, Portrait, Story, Landscape, Pin — rendered in the browser and downloaded directly.

Honest metadata

The result panel shows what the generator attests: measured difficulty versus requested, the rating basis, the uniqueness proof. If a puzzle says "hard", the solver earned that word.
