Spec-first planning
1Butterfly turns a sentence into a reviewable specification — pages, data model, workflows and open questions — before a line of code is written.
A professional website,
without the agency.
1Butterfly plans the product, designs the experience, writes the copy and builds a live, bilingual website for your business — in minutes, not months.

The platform
Everything between the idea and the launch.
Most tools generate a page. 1Butterfly builds the whole product surface — structure, content, data and design — and keeps every decision reviewable.
Design that fits the brief
Industry-aware templates and structural design directions change layout, typography and rhythm — not just the palette.
Copy written for the business
Headlines, menus, services and FAQs are generated from your brief, then checked so no placeholder text reaches the preview.
Bilingual by default
Sites ship in the local language with a full English translation and a working language switch — English-only where that's the market.
Live preview, real code
Every build produces a running application you can open, edit inline and inspect — React, TypeScript and a real database schema.
Versioned and reversible
Each generation is an immutable version. Publish, compare or roll back without losing the work that came before.
How it works
Three steps, one afternoon.
- 01
Describe the business
One paragraph is enough. 1Butterfly asks a few sharp questions, then drafts the blueprint.
- 02
Review the plan
See the pages, entities and workflows it intends to build — and change anything in plain language.
- 03
Launch the preview
A complete, bilingual site with real content, a design system and a live preview in minutes.
Showcase
Built for the businesses that run the world.
Each industry gets its own structure, tone and imagery — never the same layout in a different colour.
Global by default
Speaks your customer's language.
A salon in Budapest ships in Hungarian and English. A restaurant in Belgrade ships in Serbian and English. A studio in London ships in English. The location decides — and an explicit request always wins.

Describe it once. Refine it in plain English. Launch when it's right.
