Questions, answered.

Stacklumen is a software and web engineering company. We build and operate the Stacklumen platform (Terminal, the Stacklumen Hub, the StackIDE desktop app and Stacklumen Base) and engineer bespoke websites and applications for clients.

Terminal is the visual site builder inside Stacklumen. You design pages on a real canvas, author four breakpoint layers, fill them from a CMS and publish to a live staging link. It is in private alpha, and a site on its own domain takes a site plan. See Terminal.

The Hub is the workspace behind Stacklumen: accounts, clients, CRM, notes and billing in one place. It shares one sign-in with Terminal. Open the Hub.

Stacklumen Base is our component library and toolkit for teams that build client sites: components you copy into Terminal, whole-site templates and web tools with audit reports, at stacklumen.com/base. It also has the designer: print-accurate artboards for business cards and brand assets, with a library of every design filed by client. It is in private alpha.

Every product is documented in one place: the docs.

StackIDE is the Stacklumen desktop app for Mac and Windows. Your sites, content, brand kits, clients, inbox and code sit in one window, with Terminal’s designer in a tab, a real terminal, two-way sync between a site and a folder on your computer, and an Agents panel that starts the coding agents you already use. See StackIDE.

No. Terminal and the Stacklumen Hub run in the browser, and StackIDE opens the same workspace, sites and content. It adds what a browser cannot: a terminal, folders kept in sync, your agents and notifications on your desktop.

Nothing extra. StackIDE comes with every Stacklumen account during the private alpha, on every plan, Free included. Sites you publish from it are on the same site plans as on the web, and it runs your own agents, so there is no AI usage to pay us for. See pricing.

Macs with Apple silicon or an Intel processor, and Windows PCs on x64 or Arm. Download it from the StackIDE page while signed in to your Stacklumen account; it offers the build for your computer first. System requirements.

On a Mac, yes: from version 0.1.5, every Mac build is signed with a Developer ID and notarised by Apple, so macOS opens it as it does any app from the internet, and it updates itself. On 0.1.4 or older, download the current version once from the StackIDE page. The Windows installers are not code-signed yet, so SmartScreen may warn the first time: choose More info, then Run anyway. On Windows, updates have always installed themselves. Security and signing.

StackIDE installs as “Stacklumen” for now: that is its name in Applications, the Dock and the Start menu, and in its own window and menus. It is the same app, and it takes the StackIDE name in an update.

Yes, from its Cloud screen, in every workspace: an app is free on a site’s staging address and paid from Cloud credit once it answers on a domain. Cloning an app, running it on your computer and previewing it at tablet and phone widths cost nothing. Cloud in StackIDE.

One plan per agency covers the Hub, Terminal and StackIDE: Free, or Agency at $99.99/mo ($83.32/mo billed yearly). Stacklumen Base is its own product, at $29.99/mo ($24.99/mo billed yearly) on either plan, with a free tier on every account; templates are sold one by one. Client payments, for invoices and retainers your clients pay by card, is $20/mo on Agency, and Advanced analytics is $10/mo a site on any plan. Sites are billed one at a time: staging on the free address is always free, a site on its own domain takes Basic at $18/mo or Premium at $30/mo (Basic with Content API keys and pages that show CMS content), and a site whose CMS your own code reads takes the CMS site plan at $15/mo for its Content API keys, with no custom domain. Every site holds up to 10,000 CMS items and 200 collections, on any plan or none. Prices are in US dollars and exclude tax, and every agency can take one 14-day Agency trial with no card. Full pricing.

Free and Agency. The plan belongs to the agency, not to one app or one person, and covers every workspace the agency holds. Agency adds clients, client guests and the CRM, and includes 5 editor seats and 3 workspaces, with more seats at $18/mo each and more workspaces at $50/mo each. Yearly billing is two months free on everything. Stacklumen Base is not part of either plan: it has a plan of its own. Pro is no longer sold; an agency that holds it keeps it until it moves to Agency at a renewal, after at least 30 days' notice.

Editors: the owners, admins and members of the agency's workspaces. Each person counts once across the agency, however many of its workspaces they work in. Viewers and client guests are always free.

Yes. Each agency can take one 14-day trial of the Agency plan, with no card. Stacklumen Base and Client payments are not part of it, and are charged from the day they are bought. When it ends nothing is charged and nothing is deleted; the agency goes back to Free until someone chooses a plan.

Website builds start at $3,000 and custom applications at $15,000. The final price is set in a written proposal after we understand the scope. See pricing.

There are two offers: a framework upgrade at $300, and a full migration from $4,200. Which one fits.

Brand work is sold as fixed packages, and each one is priced on the brand pricing page.

Send a brief. We reply within one business day and send a written proposal within 3 business days, with the scope, the timeline and the price.

We build client sites natively in Terminal, our own site builder, and engineer custom applications on a modern TypeScript stack. The proposal says which fits your project and why.

Our enterprise team. While Terminal is in private alpha, enterprise builds are scoped, engineered and supported by that team directly. When Terminal reaches general availability, a marketplace of creators opens alongside it, and our internal development team is one of the creators you can choose.

It depends on the scope. Every proposal carries a timeline, and the process page shows how the work runs from brief to handover.

Lexington, KY. We work with clients remotely.

You do: the full source code, and a transfer of the platform workspace where one is involved.

Yes. Sites we deliver can be hosted and maintained by us on one plan that covers hosting, updates and small changes. The hosting page explains what it includes and costs.
