Build visually
The planned browser builder is intended to make page composition direct while preserving the structure behind every element.
Open-source website building
Lacuno is building a visual workflow for expressive websites with editable source, static output and a clear path to self-hosting.
Explore Lacuno →A real page, in view
A working example, built from the same editable Lacuno document. Explore the typography, layout and reusable sections, then make them your own.

One document, many collaborators
Lacuno keeps layout, content, styles, reusable components and collections in a structured document. That gives a future visual builder and today’s MCP workflow the same editable source of truth.

Templates are ordinary Lacuno documents. Change their words, tokens, sections and collections instead of working around a sealed theme.

The compiler produces static pages that are simple to inspect, move and host with infrastructure you control.

Planned service
A browser builder and publishing to a free subdomain with a limited page-visit allowance are planned. Availability, exact limits and pricing are not defined yet.
Open-source path
Run the AGPL builder and serve the static websites yourself. Keep the source, deployment choices and project history in your own environment.
