What's the best Google Stitch alternative?

Looking for a Google Stitch alternative that's built specifically for mobile app design? You're not alone. While Google Stitch is a capable free tool for general UI generation, many founders and developers find they need something more specialized when creating professional mobile app mockups.

We built Sleek to solve exactly this problem. Let's compare both tools so you can decide which one fits your mobile app design workflow.

Google Stitch vs Sleek: Quick Comparison

Before diving into details, here's how the two tools compare across key features for mobile app design:

What is Google Stitch?

Google Stitch is a free AI-powered design tool from Google Labs that generates UI designs from text prompts, sketches, or screenshots. It's powered by Gemini models and allows you to create web and mobile interfaces quickly without coding.

Key Google Stitch features include:

• Multiple AI models including Gemini Flash (Fast), Gemini 2.5 Pro, Gemini 3 Pro (Thinking), and Nano Banana Pro (Redesign)
• Text-to-UI generation from prompts with varying speed and quality tradeoffs
• Screenshot redesign to transform existing designs into new layouts (Redesign model)
• Prototype stitching to connect screens into clickable flows
• Figma export (Fast model only) and HTML/CSS code export
• Unlimited free use* with monthly limits: ~350 generations (Fast model) or ~50-100 generations (Pro models)

Google Stitch works well for quick exploration and early-stage ideation, especially for teams with zero budget. It's backed by Google's infrastructure and offers impressive capabilities at no cost.

Why Look for a Google Stitch Alternative?

Despite being free, Google Stitch has limitations that become apparent when you're serious about mobile app design:

Limited mobile focus. Stitch handles web and mobile UI equally, which means it's optimized for neither. When you're building a mobile app, you need a tool that understands mobile-specific patterns, spacing, and interaction models.

Generation limits. With only 50-350 generations monthly (depending on which AI model you use), you'll hit walls quickly during active design phases. Professional projects often require dozens of iterations per screen.

Limited Figma export. Figma export is only available with the Fast model (Gemini Flash), which prioritizes speed over quality. Higher-quality models like Gemini 3 Pro don't support Figma export, forcing you to choose between quality and workflow compatibility.

Workspace navigation issues. Users report that new designs don't auto-focus, making canvas navigation frustrating during rapid ideation sessions.

Generic output quality. While good for general UI, Stitch doesn't match the professional polish of tools built specifically for mobile app presentation and investor pitches.

Why Choose Sleek Over Google Stitch

We designed Sleek specifically for people who need professional mobile app mockups without the limitations of generic design tools.

Superior Mobile-First AI Quality

Sleek focuses exclusively on mobile apps. Our AI understands mobile UI patterns, visual hierarchy, and design principles that make apps look professional. Unlike tools that try to do everything, we perfect one thing.

The quality difference becomes obvious when you're pitching investors or showing mockups to stakeholders. Generic tools produce generic results. Specialized tools produce work that rivals human designers.

More Design Power

While Stitch caps you at a few hundred generations monthly, Sleek's paid plans offer 7,000 to 30,000 AI credits. That's enough to iterate freely without counting generations. You can explore multiple design directions, create variations, and refine until you're satisfied.

Generate at least 3 different app screens from your first prompt, giving you a comprehensive view of your mobile app without creating each screen separately. To explore different visual styles or color schemes, simply specify your theme preferences in your prompt description.

Professional Export Options

Every Sleek plan includes Figma export with native, fully editable layers. No plugin required. Just click the Figma button and paste directly into any Figma file. Your design appears as actual Figma layers you can edit, not flattened images.

Code exports work in HTML or React with Tailwind CSS. Developers can start building immediately without recreating designs from scratch.

Built for Real Projects

Sleek serves startup founders validating MVPs, developers who need quick prototypes, and designers exploring rapid iteration. Our tool respects your time and delivers results you can actually use for professional presentations and development handoff.

Google Stitch vs Sleek: Detailed Feature Comparison

Here's a deeper look at how both tools handle specific mobile app design needs:

Who Should Use Google Stitch?

Google Stitch makes sense when:

• Budget is zero and you need any UI generation capability
• You're exploring early concepts without commitment to a specific direction
• Web design is your focus alongside occasional mobile screens
• You want built-in prototyping to stitch screens together
• You're already in Google's ecosystem and prefer staying there

For hobbyists, students, or teams in very early exploration phases, Stitch provides genuine value at no cost.

Who Should Use Sleek?

Sleek is the better choice when:

• Mobile apps are your focus and you need specialized quality
• You're creating investor presentations that need to look professional
• Developers need code exports in React with Tailwind CSS
• You work in Figma and need native, editable layer exports
• Quality matters more than free and you're willing to invest $20-40/month
• You're iterating actively and need thousands of generations, not hundreds

If you're building mobile app mockups seriously, whether for a startup, client work, or your own app idea, Sleek's mobile-first approach delivers results that generic tools can't match.

Frequently Asked Questions

Is Google Stitch really free?

Yes, Google Stitch is marketed as free with "unlimited" use, but has monthly generation limits that reset each month. You get approximately 350 generations per month with faster models (Gemini Flash) and around 50-100 generations with higher-quality models (Gemini 3 Pro, Gemini 2.5 Pro). You can choose between different AI models with different speed, quality, and limit tradeoffs.

Can I export Google Stitch designs to Figma?

Yes, but only with the Fast model (Gemini Flash). Higher-quality models like Gemini 3 Pro and Gemini 2.5 Pro don't support Figma export, so you must choose between speed with Figma compatibility or quality without it. Sleek offers native Figma export with fully editable layers on all plans and all quality levels.

Which tool has better AI quality?

For general UI, both tools produce good results. For mobile apps specifically, Sleek's AI is trained to deliver superior quality because we focus exclusively on mobile design. The specialization matters when quality counts.

Does Sleek have a free plan?

Yes. Sleek's free plan includes 1 project with trial AI credits, plus limited Figma and code exports. It's enough to test whether our mobile-first quality meets your needs before upgrading.

Can I use designs commercially?

With Sleek, you have full ownership of all designs and code you create. Use them for personal projects, commercial apps, or client work. Check Google Stitch's current terms for their commercial use policy.

Which is better for rapid prototyping?

Google Stitch has built-in prototype stitching to connect screens into clickable flows. Sleek exports to Figma where you can build interactive prototypes with more control and fidelity.

Try Both and Decide

The best way to choose between Google Stitch and Sleek is to try both. Google Stitch is free, so you can test it immediately. Sleek offers a free plan that lets you experience the mobile-first quality difference.

If you're building mobile apps and design quality matters, we're confident you'll see why specialized tools outperform generic ones.
