Terminal builds and publishes sites. The Stacklumen Hub runs the clients, team and billing around them. Baselumen 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.

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 plan covers all of it.

Terminal and the Hub are Stacklumen; Baselumen holds the library and the designer. Start with the one that fits the work in front of you; the others are a switch away in the same frame.

Terminal

Alpha

The visual site builder: a real canvas over HTML and CSS, four breakpoint layers, a CMS, and publishing to a live staging link.
