Developer tools
Baselumen is the workbench for people who build sites: components you copy into Terminal, whole-site templates, a print-accurate designer that draws in millimetres, and browser audits with client-ready reports, with an MCP server for an agent of your own.

Agencies that ship Webflow sites rebuild the same components over and over. Stacklumen needed a production-grade, versioned library — accessibility-checked and copy-paste-ready — that stays in sync across Webflow, Figma, and React, with no lock-in.
Stacklumen designed and built Baselumen: a component-library app with an attributes reference, token generators, and site-audit tools, delivered across Webflow, Figma, and React so design and build stay aligned.
It has since grown into the whole workbench. Components and whole-site templates copy straight into Terminal, and Operalumen, the design and print product, merged into it: its millimetre canvas, with trim and bleed, and its shared brand library now live in Baselumen, where an agent can edit a design over MCP and send it to a Terminal site.
Baselumen is live in public alpha (v0.1.4) — a growing, version-tracked toolkit that lets studios drop in accessible, production-ready components and own them outright.
Full product design and build: a component-library app, an attributes reference, token generators, and site-audit tools, plus the marketing site — accessibility-checked and version-tracked.
