Move from a broad prompt to editable routes, components, styling, and assets without losing the intent of the design.
AI builder for premium web apps
Craft digital
masterpieces.
Klego turns rough ideas into polished, previewable Next.js apps with design control, real code, and a live workspace built for serious product surfaces.
The anatomy of luxury
Designed for the uncompromising.
Klego pairs a blank-canvas generation engine with an exacting review loop, so your first version can feel intentional instead of templated.
Explore all capabilities
Pixel-perfect precision.
Instant preview loop
Every generation opens inside a live sandbox, so you judge the real application instead of a static mockup.
Bespoke refinement
Select elements, adjust details, save code edits, and keep shaping the product through versioned follow-ups.
Connected pages
Build landing pages, dashboards, auth flows, portals, settings screens, and full websites from one workspace.
The process
From blank canvas to
previewable masterpiece.
Sculpt the interface
Describe the experience, visual mood, screens, states, and interactions you want Klego to compose.
Generate real code
Klego edits a Next.js scaffold, materializes assets, stores a durable version, and keeps the file tree editable.
Review the live build
Open the preview, inspect logs and diffs, then refine the app with the exact context beside you.

“Klego did not just speed up our workflow; it elevated the entire direction. It feels less like a generator and more like a workspace for design intent.”

Common questions
Everything you need
to know.
Can Klego build more than landing pages?
Yes. Klego is designed for complete web application surfaces: dashboards, portals, SaaS flows, AI tools, admin panels, and connected websites.
Does it create real code?
Yes. Generated apps are stored as editable Next.js, React, TypeScript, and Tailwind files with version history.
Can I refine the design after generation?
Yes. Use chat context, visual selection, code edits, diffs, and restore points to keep directing the result.
Where does the preview run?
Each project preview runs in an isolated sandbox and appears inside the builder workspace with logs and network details nearby.
