Every web build we deliver is designed, published and handed over in Terminal.

SupportStacklumen is a software and web engineering company in Lexington, KY. Since 2022 we have engineered websites and applications for clients, and we now build and operate the platform that work is delivered on.
Client sites are built natively in Terminal. Applications are bespoke software with authentication, data models and integrations. Either way you approve a written scope and a fixed price before work starts, and you own the code, accounts and documentation at handover. Enterprise builds run through our enterprise team while Terminal is in private alpha.

From $3,000
Marketing sites, Shopify storefronts and the content systems behind them, set up so your team can edit them the day after launch.
From $15,000
Client portals, dashboards and internal tools, with sign-in, billing and admin designed in from the start rather than bolted on.
Terminal and the Hub form the core of the Stacklumen platform; Stacklumen Base extends it with components, templates, web tools, client portals and the designer, and StackIDE brings the platform to the desktop. All four are in use today and in private alpha, with Terminal's general release to follow.
The visual site builder: a real canvas over HTML and CSS, four breakpoint layers, a CMS, forms, and one button that publishes to a live address.

See the HubThe desktop app for Mac and Windows: sites, content, clients and code in one window, with a terminal, folders kept in sync and the coding agents you already use.
See StackIDEComponents, whole-site templates, web tools and client portals for the teams that build and run websites, and a print-accurate designer for their brand work.
stacklumen.com/baseStacklumen is the third name for the same company. Client work and retainers carried across each change.
2022
Started as a small web practice: the first client sites, the first design system and the first internal component library.
2024–2025
Took on Shopify storefronts and custom React applications, and built the habits of production work: real components and complete handovers.
Now
The same company under the name it keeps: the platform on one side, the engineering practice on the other.
Experience-first product design is a term named and defined by Stacklumen founder Iain Feeney. It holds that the experience of using a product is not packaging around its value. It is how the value arrives, how people come to understand it, and why they stay.
Every Stacklumen product invites the people using it into an experience that drives value, creates happiness and helps them succeed, like the branded strategy wizard, where an agency and its client build the client’s business together, live, one question at a time. Read the essay.
We believe every business deserves infrastructure that works as hard as it does. Stacklumen exists to engineer it: with precision, with rigour, and with outcomes measured in production rather than promised in a deck.
