Figma alternative

Why teams pick Builderii
Describe an app or a website and the AI draws its screens in device frames, already linked, with a start screen, ready to play.
Flowcharts, mind maps, sitemaps and sticky notes sit beside the screens they describe. No second file, no second tool.
One switch (⇧W) moves every screen between a sketchy wireframe and your brand. Rendered redraws them as final designs with real photos.
Link any element to a screen, choose click or hover and a transition, then press ⌘↵ to play.
Share a test link and get tap heatmaps, time on each screen and where people stopped, without a separate testing tool.
Paste your website: Builderii reads its colours, fonts and corner rounding and puts them on every high-fidelity screen.
Turn a screen into a live HTML preview and a React and Tailwind component to hand to engineering.
An MCP server with 37 tools lets your AI assistant draw and change boards for you, as you.
Switching
Type what you’re building on Home, or press / on any board and pick App screens. Choose Mobile or Web.
A screenshot of an existing screen becomes an editable wireframe. A pasted Figma link shows on the board as an embed.
Share as editor, commenter or viewer, or turn on a link. Everyone works live on the same board.
Play the prototype, share a test link, or present your frames as slides with speaker notes.

Which to pick
Questions
Yes. Builderii is free while it’s new, with every feature on and 500 AI jobs a month per person. Viewers and commenters will always be free, and paid plans will publish their AI allowances.
For early product work, such as user flows, wireframes, clickable prototypes and quick tests, yes. For final pixel-perfect UI, design systems and Dev Mode handoff, Figma is still the tool. Many teams use Builderii first and Figma after.
There’s no Figma file import. Paste a Figma link and it shows on the board as an embed, or give the AI bar a screenshot of a Figma screen and it becomes an editable wireframe.
Builderii’s AI works on the canvas: linked app screens, flowcharts, mind maps and more from a prompt, edits in place when you ask, Rendered final designs styled after real apps, and HTML and React code for any screen.
Yes. Everyone on a board sees live cursors and edits as they happen, can follow someone’s view, chat at their cursor and leave comments with @mentions that send a notification and an email. Invite people as editors, commenters or viewers, or share a link.
