The Stacklumen platform is in public alphaSee the products

Building the agentic future of
agency management.

Production websites and custom software, engineered for clients on a platform we build ourselves.

Open Terminal See pricing

Terminal, the Stacklumen site builder, in its light frame: one bar with the site and page, four breakpoint layers, zoom, Preview and Publish; the Insert panel of section presets; a client page on the canvas; and the inspector with its state tray and property groups. A short demo plays: the cursor opens Typography, drags the heading from 46 to 58 pixels, retypes its last words on the canvas, then walks the page through Tablet and Phone and back.

What you set is what ships. To the pixel.

The canvas, the preview and the published page read the same values. Size the heading, set the padding, pick an accent, then bind the cards to a collection.

What is late, what is unbilled, and which client it belongs to.

Client work by stage, with the timer on the card.

Every client, and what each one has running.

One plan for the agency across every app, and a plan for each site on its own domain.

One suite, one account. Each app hands its work to the next.

YourVision, the brief a client answers in the Stacklumen Hub, drawn with its questions beside it: company, design style, colour, project type, timeline, and whether the site needs a CMS or logins. The answers fill a one-page brief. On Finish, the brief shows what follows: a first reply within one business day and a written proposal in 3 business days, from $3,000 for a web build or $15,000 for custom software. A short demo plays through the steps; the pause button stops it, and every question can be answered by hand.
