Comparison Table

1. CatDoes

CatDoes turns a plain-language description into a working native mobile app. You describe what you want, and a system of specialized AI agents handles the rest: one captures requirements, another designs the UI, and a third writes React Native (Expo) code. An automated build agent then packages the app for the App Store and Google Play.

In our testing, we described a habit tracker app and had a working prototype with user authentication, a database, and push notifications within 10 minutes. The platform provisions a full Supabase backend automatically, database, auth, storage, and server-side logic, so you do not need to configure anything separately. You can preview apps in a browser or scan a QR code to test on your phone.

The free plan lets you build and test one app. Paid plans start at $25/month and add more projects, deployment to all platforms, and GitHub integration. CatDoes is the only AI builder on this list that ships native mobile apps to both app stores from a single prompt.

• Best for: Non-technical founders, startup MVPs, and anyone who needs a native iOS or Android app without writing code.

2. Lovable

Lovable (formerly GPT Engineer) is one of the fastest-growing AI app builders, reaching $200 million in annual recurring revenue by late 2025. You describe your app in natural language, and Lovable generates a complete full-stack web application, frontend, backend, database, and authentication, in real time.

The platform generates clean React and TypeScript code with Tailwind CSS styling and a Supabase backend. Its Agent Mode lets the AI work autonomously, exploring code, debugging, and even searching the web for solutions. We found Agent Mode impressive for complex tasks but credit-hungry, a single debugging session can consume 5-10 credits. Visual editing lets you click directly on UI elements to modify them without writing prompts.

The free tier gives you 5 credits per day for public projects only. The Pro plan costs $25/month and adds private projects, custom domains, and more credits. One key limitation: Lovable only generates responsive web apps. It cannot produce native iOS or Android apps for the app stores.

• Best for: Founders building web-based MVPs, internal tools, and SaaS prototypes who want clean, exportable code.

3. Bubble

Bubble is one of the most established no-code platforms, and its AI assistant adds a useful starting point. Describe your app, and the AI generates a database structure, page layouts, and backend workflows. From there, you customize everything in a visual editor with a large plugin marketplace.

Where Bubble shines is depth. Its workflow engine handles complex multi-step business logic that simpler AI builders struggle with. The plugin library covers payments, maps, charts, and more. Bubble is web-only, so native mobile apps require a wrapper or a separate tool. If you are choosing between Bubble and a mobile-first builder, see our CatDoes vs. Bubble comparison.

A free plan is available for learning. Paid plans now start at $29/month (Starter) and scale by workload units, which can be hard to predict at higher traffic. Bubble recently restructured its pricing to a capacity-based model, so review your expected usage before committing to a plan.

• Best for: SaaS products, marketplaces, and custom web apps that need deep logic and a mature ecosystem.

• Website: bubble.io

4. FlutterFlow

FlutterFlow pairs Google's Flutter framework with a visual builder. Its AI generates pages, components, and full app templates from text prompts. The result is natively compiled code that runs on iOS, Android, web, and desktop from a single codebase.

The biggest advantage is code ownership. FlutterFlow generates clean, exportable Flutter and Dart code. You can download it, push it to GitHub, and hand it to a developer for custom work. That makes it a strong choice for teams who want visual speed now but need full code control later. The learning curve is steeper than prompt-based builders like CatDoes or Lovable, but the flexibility rewards the investment.

A limited free tier is available. Paid plans start at $39/month (Basic), up from $30 in 2025. Higher tiers add team collaboration, deployment, and code export. FlutterFlow retired its legacy Pro and Teams plans in late 2025 and introduced regional pricing for select countries.

• Best for: Cross-platform MVPs, Flutter developers, and teams that need exportable source code.

• Website: flutterflow.io

5. Base44

Base44 takes a backend-first approach to AI app building. Instead of starting with the UI, it defines your data schema, builds APIs, and sets up authentication before generating the interface. The platform was acquired by Wix for $80 million in June 2025 after just six months of operation and has grown to over 2 million users.

A standout feature is Discuss Mode, which lets you brainstorm with the AI architect before it writes any code. You can ask questions about design decisions, adjust logic, and plan your data structure collaboratively. The platform auto-selects between Claude Sonnet 4 and Gemini 2.5 Pro for code generation, though you can override the model choice. In-app code edits are available even on the free plan.

The free tier includes 25 message credits per month (5/day cap). The Starter plan costs $20/month for unlimited app creation. Code export is available on the Builder plan ($49/month), but exported code depends on a proprietary SDK tied to the Base44 and Wix infrastructure. Like Lovable, Base44 produces responsive web apps only, no native mobile output.

• Best for: Rapid prototyping, data-driven web apps, and solo makers who want an all-in-one stack without managing infrastructure.

• Website: base44.com

6. Replit

Replit Agent is an autonomous AI coding agent that turns natural-language descriptions into full applications. It sets up the project structure, generates frontend and backend code, and then tests its own output in a browser, fixing bugs automatically before handing the result back to you.

Agent 3 (the latest version) supports over 50 programming languages and frameworks, but works best with JavaScript, TypeScript, and Python. It offers Lite Build for quick prototypes (3-5 minutes) and Full Build for comprehensive apps (10+ minutes). A Max Autonomy mode lets Agent work continuously for up to 200 minutes. You can also import projects from Lovable, Bolt, or GitHub and continue building inside Replit.

The free Starter plan includes limited daily Agent credits and one published app. The Core plan costs $25/month and includes $25 in usage credits for Agent, deployments, and databases. One thing to watch: Replit uses effort-based pricing for Agent checkpoints, so costs vary by task complexity. Heavy users report spending $100 to $300 per month beyond the base plan.

• Best for: Developers and technical builders who want full-stack prototyping with direct code access and flexible deployment.

• Website: replit.com

Building a mobile app? Most AI builders on this list produce web apps only. If you need a native iOS or Android app, build a mobile app without coding using a platform designed for mobile from the start.

7. v0 by Vercel

v0 is Vercel's AI-powered development platform. You describe a UI or full-stack feature in plain language, and v0 generates working React components, pages, or complete Next.js applications. It uses a composite AI architecture: retrieval for context, a frontier LLM for reasoning, and an AutoFix post-processor that catches errors during generation.

The output is always React, TypeScript, and Tailwind CSS with shadcn/ui components. If your stack is Next.js, v0 fits in seamlessly, one-click deployment to Vercel, GitHub sync, and environment variable linking are built in. Design Mode lets you visually edit generated components, and Figma import converts designs to working code. The trade-off is ecosystem lock-in: if you do not use React and Next.js, the output requires significant rework.

The free plan includes $5 in monthly credits and 7 messages per day. The Premium plan costs $20/month with a $2 daily login bonus. v0 offers three AI model tiers (Mini, Pro, Max) so you can trade quality for cost depending on the task.

• Best for: React and Next.js developers, UI prototyping, and teams already deploying on Vercel.

• Website: v0.dev

8. Retool

Retool is built for internal tools. Its AI generates full-stack apps directly from your database schemas, complete with permissions and live data connections. You can also create deployable AI agents that access company data and perform tasks across your software stack.

Security is the main selling point. Retool includes role-based access control, single sign-on, audit trails, and deep integrations with dozens of data sources. It is not meant for consumer-facing apps. It is purpose-built for operations dashboards, admin panels, and support tools that need strict access controls.

Free for up to 5 users. Paid plans start at $10 per user per month (billed annually), with AI and agent usage billed separately. Costs can scale quickly for larger teams, especially with the new per-hour AI agent consumption pricing.

• Best for: Operations teams, data-heavy internal tools, and companies that need enterprise-grade security.

• Website: retool.com

9. Microsoft Power Apps

Power Apps brings Microsoft Copilot into a low-code builder. Describe your app in plain language, and Copilot creates data tables in Dataverse and generates an initial UI. From there, you connect to hundreds of Microsoft data sources including SharePoint, Dynamics 365, and Azure services.

The main draw is deep Microsoft integration. If your company already runs on Microsoft 365, Power Apps fits in without friction. It includes enterprise-grade governance, security, and administration. Outside that ecosystem, it offers less value.

Power Apps pricing changed significantly in early 2026. Microsoft discontinued the $5 per-app plan in January 2026, pushing users to the Premium plan at $20 per user per month, double the previous entry price. A pay-as-you-go option exists at $10 per active user per app per month. A developer plan is available for non-production use, but there is no general free tier. Licensing complexity remains a common complaint.

• Best for: Large enterprises and IT departments already invested in the Microsoft 365 and Azure ecosystem.

• Website: powerapps.microsoft.com

10. Glide

Glide turns spreadsheets and databases into polished mobile-first apps. Its AI features include AI columns that run text generation, image analysis, and data extraction directly in your app's data layer. The Glide Agent generates a full app from a plain-English description, and the 40+ pre-built components cover most common patterns like directories, trackers, and simple CRMs.

What sets Glide apart is the design quality. Apps look professional out of the box, which matters for client-facing internal tools. Glide restructured its pricing in November 2025 and now starts at a more accessible $19/month (Explorer) billed annually, down from $49. However, the Business plan jumped to $249/month, and per-user costs for customer-facing apps can add $5 to $6 per user per month.

A free plan is available for one app with up to 10 personal users. Glide is not the right fit for apps with complex custom logic or consumer-facing products that need native mobile deployment.

• Best for: Internal tools, lightweight client portals, and turning spreadsheet data into apps fast.

• Website: glideapps.com

11. Adalo

Adalo focuses on getting mobile apps built and published with minimal friction. Its drag-and-drop editor, integrated database, and component marketplace make it straightforward to assemble functional apps for iOS and Android. It does not use generative AI, but its visual builder is simple enough that most people can ship an MVP in a weekend.

The publishing workflow is one of the smoothest in the no-code space. Adalo handles the App Store and Google Play submission process, which saves hours of configuration. Adalo 3.0, a recent infrastructure overhaul, delivered 3-4x faster app performance. The trade-off is limited backend power, complex data logic may require connecting an external backend like Xano or Supabase.

A free plan is available for learning and prototyping. Paid plans start at $36/month (billed annually) or $45/month on a monthly basis, with limits on database records and app actions on lower tiers.

• Best for: First-time app builders, mobile MVPs, and small businesses that want a direct path to the app stores without AI complexity.

How to Choose the Right AI App Builder

Start with what you are building. Native mobile app for the App Store? CatDoes, FlutterFlow, or Adalo are your options, everything else on this list produces web apps. Custom web application with complex logic? Bubble gives you the most control. AI-generated web MVP as fast as possible? Lovable, Base44, or Replit will get you there. Internal dashboard for your team? Retool, Power Apps, or Glide are purpose-built for that.

Next, consider your technical level. CatDoes, Lovable, Base44, and Glide are true no-code app builders, zero coding knowledge required. FlutterFlow and Bubble have a learning curve but reward the investment with more flexibility. Replit, v0, and Retool work best for people comfortable reading and editing code. According to G2's no-code platform rankings, ease of use is the top factor in user satisfaction, pick a tool that matches your skills today, not the one you hope to grow into.

Budget is another filter. Several platforms charge a flat monthly fee: CatDoes ($25), Lovable ($25), Bubble ($29), FlutterFlow ($39). Others charge per user (Retool at $10, Power Apps at $20), which works for small teams but gets expensive fast. Credit-based platforms like Replit and Base44 can have unpredictable costs at scale. Always estimate your cost at the usage level you expect in 6-12 months, not just what it costs on day one.

Finally, think about lock-in. FlutterFlow exports clean Flutter code you can host anywhere. Replit gives you direct code access by default. Lovable syncs with GitHub for full code export. Base44 exports code but it depends on a proprietary SDK. Most other platforms keep your app on their infrastructure. If full code ownership matters, that filter alone cuts the list in half.

FAQ

What is an AI app builder?

An AI app builder is a platform that uses artificial intelligence to help you create software applications without writing code from scratch. Some, like CatDoes and Lovable, generate entire apps from a text description. Others, like FlutterFlow and Bubble, use AI to speed up specific tasks like designing layouts, writing code, or building database schemas. The level of AI involvement varies widely, from fully autonomous generation to AI-assisted visual editing.

Can I build a real mobile app with these tools?

Yes, but only a few platforms on this list support native mobile apps. CatDoes generates React Native code and handles App Store and Google Play submissions. FlutterFlow generates Flutter code for iOS, Android, web, and desktop. Adalo uses its own runtime for mobile deployment. The AI-native platforms (Lovable, Base44, Replit, v0) produce responsive web apps that work in mobile browsers but cannot be submitted to the app stores as native apps.

Do I need coding skills to use an AI app builder?

Most platforms on this list require no coding. CatDoes, Lovable, Base44, Glide, and Adalo are designed for people with zero programming experience. FlutterFlow and Bubble offer more power but come with a steeper learning curve. Replit, v0, and Retool assume you are comfortable reading code and working with databases.

Which AI app builder is best for beginners?

CatDoes has the lowest barrier to entry for mobile apps, you describe your app in plain language and the AI handles the technical work. For web apps, Lovable and Base44 are the easiest starting points. Glide is a strong option for data-driven internal tools. All four offer free plans so you can test before paying.

How much do AI app builders cost?

Most offer a free tier for testing. Paid plans range from $19/month (Glide Explorer) to $39/month (FlutterFlow Basic) for flat-rate platforms. Enterprise tools like Retool ($10/user) and Power Apps ($20/user) charge per seat. Watch out for usage-based pricing: Replit and Base44 charge per AI interaction, which can push real-world costs well above the headline price. CatDoes starts at $25/month with predictable credit-based pricing.

Final Verdict

The AI app builder market in 2026 splits into two clear categories: platforms that ship native mobile apps and platforms that generate web apps. If you need an app in the Apple App Store or Google Play, your realistic options are CatDoes (the fastest, no-code path), FlutterFlow (exportable Flutter code with a learning curve), or Adalo (simple drag-and-drop with smooth publishing).

If you are building for the web, you have more choices. Lovable and Base44 offer the fastest path from prompt to working product. Bubble gives you the deepest customization for complex web applications. Replit and v0 are strong picks for developers who want code-level control. For enterprise internal tools, Retool and Power Apps remain the leaders.

No single platform is the best for everyone. The right choice depends on your output target (mobile vs. web), your technical level, your budget, and how much you care about code ownership. Start with the free tier of 2-3 platforms that match your use case, build the same simple app on each, and see which one gets you closest to what you need.
