Hero & features
The sections every launch page needs, as blocks with typed fields. Reposition the product without rebuilding the page — it’s a headline edit, not a deploy.
Marketplace starter · Lumen UI
A SaaS marketing site template your whole team can edit.
Lumen UI is a complete SaaS marketing site — hero, features, pricing, and FAQ — built from Svelte blocks with typed fields. Your agent redesigns the pricing page as code; marketing fixes the headline in the browser. Same files, no handoff queue.
What's included
Pricing
Pricing as content. Change a number, a tier name, a feature line — in the browser, on the rendered page, without waiting on an engineer.
FAQ
A repeater of question-and-answer pairs. Support hears the same question twice, adds it to the page once.
Typed fields
Every block declares its fields in fields.yaml — text, rich text, image, link, repeater. The editor UI is generated from that schema, no glue code.
Real-time collaboration
Multiple people in the same page at the same time — live presence, conflict-free edits. Launch-day copy changes without the merge conflict.
Yours to own
A complete, self-contained site — Svelte components in your repo, MIT-licensed. No framework lock-in, no hidden runtime.
