Company

A builder that shows its work.

Comlumen is a visual site builder: a drag-and-resize canvas and a writable code pane, both editing the same document at the same moment. It is built by Stacklumen, alongside four sibling products, for the people who ship client sites for a living.

What Comlumen is

Two co-equal editors, one document.

Not a canvas with an export button, and not a code editor with a preview. The canvas and the code pane dispatch into the same reducer, share one undo history, and neither is generated from the other. That is the product; everything else on this site is a consequence of it.

The designer, surface by surface Open it — no account

The positions

Four things this product will not trade away.

Each of these is argued in full somewhere on this site. This is the short form, gathered in one place.

01

The code panel is an editor, not a preview

Most visual builders make the canvas authoritative and generate code out of it — a panel you can read and cannot meaningfully write. Here both views dispatch into one reducer, so dragging a box and typing a number are the same operation.

How the model works
02

Your markup, your stylesheet

Semantic tags, your class names, and CSS you wrote. What comes out is a page you could have hand-built — no runtime to include, no format to be trapped in. Leaving is copy and paste, which is a feature, not a leak.

See code mode
03

Built for agencies

Presets are copied by value so a library change cannot reach into a client’s published homepage. The suite around it — portal, components, workflow tools — exists because shipping client sites is the job, not a use case.

How the suite fits
04

Claim only what exists

Status chips are read from one file. Unbuilt work is named, never described in the present tense — the pricing page says its numbers are placeholders, and the roadmap lists the problems as problems.

Where the line is

Who builds it

Built by Stacklumen.

Stacklumen makes tools for agencies and freelancers, and Comlumen is one of five. They share an account and a design system; otherwise each stands alone, and you can use exactly one of them. Comlumen is a satellite of stacklumen.com — sign in anywhere in the suite and you are signed in here.

What is shared, and what deliberately is not
Stacklumen

The parent company, the console, and the account all five products share.

 Hublumen

Client portal — status, approvals, file delivery and billing in one workspace.

 Baselumen

The component library the designer imports from, live, in a panel.

 Kitlumen

Tools for the jobs either side of designing a page.

Where it is

A young product, measured rather than promised.

No founding story and no headcount here — this page states only what can be checked. The bar below is computed from the same file the roadmap renders, so this page cannot describe a product the roadmap disagrees with.

The rest of the introduction is the product.

The designer boots with a document already in memory. No account, no card — drag a box, switch to code, and watch the same edit arrive in both.
