Pick Builderii if…
- You plan apps as well as websites

Relume alternative
Relume made AI sitemaps and wireframes the starting point for web designers. Builderii does the planning on an infinite canvas: a sitemap with each page’s sections, page wireframes in browser frames, your brand from your current site, and a prototype you can send to a client or a tester.

In short
Builderii is a Relume alternative for planning websites and apps: its AI draws a sitemap with each page’s sections and wireframes pages in browser frames, your brand comes from your current site’s address, and the pages link into a clickable prototype you can test. App screens, user flows and workshops share the board. Relume is the better pick for building marketing sites in Webflow or Figma with its component library.
