Terminal builds and publishes sites. The Stacklumen Hub runs the clients, team and billing around them. Stacklumen Base supplies components, templates and web tools, and its designer carries brand work from brief to proof. They share one shell: the rail, the top bar and your place in the system. StackIDE puts the same work on the desktop, beside your code and your agents.

The Overview reads the records the Clients screen writes. Nothing is copied between them.

The Stacklumen Hub, live. The rail changes the screen, never the frame, and every screen reads the same records.

The line-up. One account holds all of it.

Terminal and the Hub are Stacklumen, and StackIDE brings both to your desktop; Stacklumen Base holds the library and the designer. Start with the one that fits the work in front of you; the others are a switch away on the same account.

StackIDE

Alpha

The Stacklumen desktop app for Mac and Windows: your sites, content, code and terminals in one window, each site kept in two-way sync with a folder, and the coding agents you already use started in that folder, its .mcp.json already naming Stacklumen's MCP server.

Mac: Apple silicon and Intel, notarised by Apple
Windows: x64 and arm64
Agents: Claude Code, Codex, Gemini CLI and six more
Sync: Two-way, your copy kept aside on a conflict
Updates: Downloaded in the background, installed on restart

A short demo of StackIDE, the Stacklumen desktop app, plays: Claude Code, started from the Agents panel, opens full size in Lumi, tightens the hero heading and adds a call to action, and the open file updates; the heading is rewritten and saved, and the Designer tab shows it live; the status bar's Publish button puts Northgate live, step by step.
