Beta

Design and ship sites, in one surface.

A visual canvas with the code underneath it. Drag, resize and place by hand, or edit the markup and assign classes directly — both are editing the same document, and neither is an export of the other.

No credit card. Part of the Stacklumen suite.

Two modes, one document

The code panel is an editor, not a preview.

Most visual builders make the canvas authoritative and generate code out of it. You can read that panel; you cannot meaningfully write in it, because the next drag regenerates over the top. Comlumen runs both views over one model, so dragging a box and typing a number are the same operation.

How it works

A page has a spine.

01

Sections stack

Vertical is flow. Add a section and everything below moves down for free — so a page can be reordered, and a hero can be swapped without hand-moving the footer.

02

Inside is free

Within a section, everything is positioned to the pixel with eight resize handles and an 8px snap. That is the part a design tool is actually for.

03

Breakpoints cascade down

Edit at Phone and Desktop never sees it — the same rule as a max-width query. Overridden fields are marked, so you know the blast radius before you make the change.

04

Classes carry the design

Every element has a class list, and the stylesheet that gives those classes meaning is right there beside the canvas. Change the button once, not forty times.

Start from something

Sections that already exist.

Navbars, heroes, feature grids, pricing tables and footers, each with its own stylesheet. Place one and edit it — nothing is locked, and nothing links back to a template that can change under you.

Presets

Seven ready sections covering navigation, hero, content, commerce and footer. Copied by value, so editing yours changes only yours.

Your own blocks

Save any section to the workspace library and place it on another page. Placement records the link, so you can see where a block is used without it silently changing a published site.

Real markup

Semantic tags, class lists and a stylesheet you wrote. What comes out is a page you could have hand-built.

Open it and move something.
