Software for how
we work
and learn.
A platform for the teams who build the web, apps and games for everyday life, and engineering for clients who need something built. Every product is designed experience-first.
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. Between those steps the window changes to StackIDE, the Stacklumen desktop app, with the same site open: the page opens from its folder, Claude Code tightens the heading from a terminal, the heading is rewritten and saved, and the Designer tab shows it live; another time the site is published from the sidebar and Pulse counts up the week. StackIDE comes with links to download it and to read about it.
Save any section as a component to reuse it across pages.
Designs you save from a page appear here, ready to drop in.
Select a card on the canvas to bind it to a collection.
Make repeating (12 items)Buildings that hold their light.
Homes, schools and libraries, drawn around the daylight.

Every site in a folder. Every agent in the terminal.
StackIDE is the Stacklumen desktop app for Mac and Windows. Each site syncs to a folder both ways. Claude Code, Codex and the other agents run in a real terminal, and in a synced site’s folder they’re already connected to the workspace. Publish is one click away in the status bar.
- Folder sync → Every site is a folder on your computer, synced both ways, with conflicts kept rather than lost.
- Terminal and agents → Claude Code, Codex, Gemini CLI and more run in a real terminal, and in a synced site’s folder they’re already connected to the workspace.
- Cloud deploys → Clone, run and preview apps on your computer, and deploy what you push: free on a site’s staging address.
- One-click Publish → From the status bar, every step shown as it runs, and the address once it is live.
- Keyboard-first → ⌘K for anything, ⌘1 to ⌘9 for each section, ⌘S to save straight to the site.
One workspace behind every client. From the board to the bill.

Stacklumen
/ Proposal
Not in scope.
Every proposal names what it does not cover, in writing, before anyone signs — so the answer arrives now rather than in week five.
SOC 2
Not certified. Every proposal says so in writing rather than leaving it to be assumed.
HIPAA / BAA
Not currently available. We can scope an engagement to avoid PHI; talk to us if you need a BAA.
Penetration testing
Self-tested internally; there is no third-party penetration test report yet.
DTC advertising
Calibrated for law firms, medical practices and warehousing — not direct-to-consumer.
No project is initiated, and no work is performed, without a signed proposal that supersedes anything shown here.

Who owns what.
You retain all rights to the data, files, comments and other content you submit ("customer content"), and you give Stacklumen a limited licence to host, store, transmit, display and process it as needed to provide the services you have asked for. You are responsible for having the rights to submit it.
Stacklumen retains all rights in (a) the products, including all software, designs, templates and documentation; (b) pre-existing tools, libraries, frameworks and patterns, including Stacklumen Base, our component library, design tokens, internal templates, and the SDFC, SDF, SAF and SLF framework tiers; and (c) generic patterns, methods and know-how developed through providing services.
For deliverables produced under an SOW, rights are granted as that agreement specifies: on delivery the client holds a licence to use, host, modify and extend the deliverable for as long as invoices are current, and outright copyright transfer is available where the SOW or another signed agreement provides for it. Either route covers the deliverable only, never the frameworks and pre-existing material above. Where this section and a signed SOW differ, the SOW controls.
They supplement, and do not replace, any signed statement of work (SOW), mutual non-disclosure agreement or other written agreement. Where a signed agreement conflicts with these terms, the signed agreement controls for that matter.

StackIDEThe desktop app for Mac and Windows
StackIDE, the Stacklumen desktop app for Mac and Windows, with the same site open. Between the designer’s steps, short demos play: the home page opens from the site’s folder while Claude Code and Codex work in Lumi, StackIDE’s window for agents, each under its own name; Lumi steps from one session to the next, Claude Code’s edit to the heading lands in the open file, and the heading is rewritten, saved and shown live in the Designer tab; then the site is published from its row in the sidebar, and Pulse counts up the week’s publishes, form submissions and agent edits.
