10 Best Free App Builders and App Makers (2026)

TL;DR: The best free app builder depends on your goal. CatDoes turns a text prompt into a published app or website with a managed backend. FlutterFlow exports real Flutter code. Glide and Google AppSheet turn spreadsheets into business tools. Below we compare 10 free app makers and app builders, with exactly what each free tier lets you ship.

Building a mobile app once meant a big budget and a team of developers. Today a free app builder can take you from idea to working prototype in an afternoon. The catch is that "free" means something different on every platform. Some give you a generous tier you can actually launch on, while others are really a trial that pushes you to pay before you publish.

We signed up for 10 free app builder and app creator platforms in 2026 and tested what you can build without paying. For each one below you get its free tier limits, honest pros and cons, the type of user it suits, and a one-line use case. The right pick depends on your project, your skill level, and where you want to end up.

How We Evaluated These Free App Builders

We signed up for each free tier in 2026 and scored it on five things:

• Free tier generosity: what you can build and ship without paying, including user caps, project limits, branding, and feature restrictions.

• Ease of use: how fast a non-technical user gets from sign-up to a working prototype.

• AI capabilities: whether the platform offers AI app generation, and how well it works in practice.

• Output type: native iOS/Android apps, Progressive Web Apps (PWAs), or both. This affects app store publishing and performance.

• Path to production: how clear and affordable the jump is from free prototype to a published app.

1. CatDoes

CatDoes is an AI-native builder that turns a plain-language prompt into a production-ready app or website. Its Compose agent runs a multi-agent workflow in the cloud, handling requirements, UI design, and cross-platform React Native Expo code, so non-technical founders can ship without touching the development stack. Of every free app builder we tested, it automates the most of the process end to end.

Instead of templates or drag-and-drop, CatDoes builds the whole project through conversation. CatDoes Cloud auto-configures the backend on every plan, including authentication, database, file storage, edge functions, and realtime, with US and EU regions. You can preview live in a browser or scan a QR code to test on a real iPhone or Android device, then deploy to the web with a custom domain, or to the App Store and Google Play. An App Store review simulation, GitHub import, and built-in error monitoring round it out. For background, see our guide to no-code mobile app development.

The free plan covers one full project, including the AI workflow, the managed backend, and live testing, with web deployment included. Paid tiers add native App Store and Google Play deployment, more projects, higher usage, GitHub integration, and code export at transparent pricing. It is best for non-technical founders, startups building an MVP, and agencies that want to accelerate delivery.

Pros:

• True end-to-end AI automation from prompt to native apps and websites.

• Auto-configured managed backend (auth, database, storage).

• Fast cross-platform testing on real devices.

2. FlutterFlow

FlutterFlow is a visual builder for native mobile, web, and desktop apps on Google's Flutter framework. Unlike tools that lock you into a closed ecosystem, it generates clean, production-ready Flutter code, which makes it a strong pick for teams that want to start visual and later hand real code to developers.

The free tier covers two projects with the visual builder, templates, API integrations, and the DreamFlow AI engine for prompt-based UI, but no code export, custom domains, or app store deployment. After the 2025 pricing change, paid plans start at $39/month (Basic) for code export, $80/month (Growth) for one-click deploy, and $150/month (Business) for team collaboration, all with unlimited projects. It suits startups building an MVP, designers making functional prototypes, and developers speeding up Flutter work.

Cons

• Code export and deployment start at $39/month.

• No built-in database; bring your own Firebase or Supabase.

• Steeper learning curve than simple drag-and-drop tools.

3. Glide

Glide turns spreadsheet and table data into AI-enhanced web apps. It builds Progressive Web Apps rather than native apps, pulling from Google Sheets, Glide Tables, or Big Tables that now hold up to 10 million rows. For data-driven internal tools, client portals, and inventory trackers, it is one of the best free app makers.

The free plan is generous for prototyping, with unlimited drafts, two editors, and up to 25,000 data rows, plus AI columns that classify data or generate text and a workflow builder for automation. Scaling to production needs the Explorer ($19/month), Maker ($49/month), or Business ($199/month) plans for more users, higher update limits, and advanced integrations. It fits business analysts, small business owners, and anyone building a functional app from existing data.

Cons

• Builds PWAs only, with no App Store or Play Store publishing.

• Update-based billing can surprise users with limits.

• Per-user costs add up at scale ($5 to $10/user/month).

4. Thunkable

Thunkable is a no-code path to truly native iOS and Android apps. Its AI Builder generates working apps from text prompts, adding a "vibe coding" layer on top of the visual editor, while the block-based logic system keeps it accessible for beginners, educators, and students.

The free plan is built for learning and testing. You can build your app and test it on your own phone, which is a real advantage for seeing how it behaves. Push notifications, AdMob, and app store publishing are paid, starting at $15/month for a basic app and $45/month with AdMob. Free projects are public and capped at three projects, five screens each, and 200MB of storage. It is ideal for students, hobbyists, and founders building a basic native prototype.

Cons

• App store publishing requires a paid plan ($15+/month).

• Free projects are public and limited to five screens each.

• AI features use tokens that are limited on lower tiers.

5. Adalo

Adalo is a popular no-code platform for building native mobile and web apps with a simple drag-and-drop interface. The recent Adalo 3.0 overhaul makes apps 3 to 4x faster with modular scaling, and an AI Builder announced for early 2026 will add prompt-based creation. That makes it a solid app creator for entrepreneurs validating a consumer-facing app fast.

The free plan lets you design, build, and test with unlimited screens, a template library, and real-device preview. Its clear "build free, pay to publish" model means you can fully develop a concept before paying to launch on the App Store or Google Play. The main limits are a low data cap (currently 200 rows per app) and Adalo branding. It suits startups building a first MVP, small business owners, and hobbyists.

Cons

• App store publishing is a paid-only feature.

• Free plan has a low database record limit (200 rows).

• Performance can slow on complex or high-traffic apps.

6. Draftbit

Draftbit focuses on React Native, which makes it a strong developer pick. Its visual builder produces clean, readable code you can extend, so you get visual-builder speed with a path to export and customize source code later.

The free plan is for exploration, with two projects capped at five screens each, now joined by AI code assistance and AI image generation in the builder. The value becomes clear on the Pro plan at $59/month, which unlocks full source code export, unlimited screens, and direct app store publishing. It fits React Native developers, startups building a native MVP, and designers making code-backed prototypes.

Cons

• Free plan is limited (two projects, five screens).

• Pro plan at $59/month is required for production use.

• Deeper customizations still require coding knowledge.

7. Bravo Studio

Bravo Studio takes a design-first approach, converting Figma designs directly into native iOS and Android apps. Designers who want pixel-perfect control will like keeping Figma as the primary design surface instead of rebuilding layouts in a separate tool.

You connect Figma files using "Bravo Tags," labels that define native behaviors like navigation, API calls, and animations, with backend support for Xano, Supabase, and Backendless. The free tier is for learning and prototyping and cannot publish to the stores. Paid plans start at $22/month (Solo) for up to 30 screens and $121/month (Team) for 80 screens with no branding. It is best for design-led teams and Figma-first founders.

Cons

• App store publishing requires a paid subscription.

• Free and lower tiers cap screen imports.

• Requires proficiency in Figma.

8. Google AppSheet

Google AppSheet is a no-code platform for data-driven apps that connect with Google Workspace and other sources. It turns Google Sheets, Excel, or database data into functional internal tools, which makes it a great free app maker for teams already in the Google ecosystem.

You can build, test, and share an app with up to 10 users for free, which is perfect for gathering feedback before a wider rollout. Its core strength is generating useful tools from existing data so business users can solve their own problems. Larger deployments, advanced governance, or public-facing apps need a paid plan such as Core or Publisher Pro. It fits business analysts, operations managers, and IT teams building internal tools.

Cons

• Mainly built for internal, data-centric apps.

• Production and public apps require paid plans.

• UI customization is more limited than some rivals.

9. MIT App Inventor

MIT App Inventor is a foundational visual programming tool, started at Google and now maintained by MIT. It is a completely free, web-based environment that uses block-based coding to make app development accessible to anyone, which makes it a great pick for education, first-time creators, and quick Android prototyping.

Its focus is learning and experimentation, yet you can build surprisingly capable apps that use device sensors, maps, and media. Android is its strong suit, where you build and share APK files easily, while iOS builds are possible but need more setup. The whole platform is free with no feature restrictions, though it is not meant for commercial-grade, scalable apps. It is ideal for students, educators, and hobbyists.

Cons

• Not designed for complex, commercial-grade apps.

• iOS build process is more complicated than Android.

• Interface and final app design feel dated.

10. Appy Pie

Appy Pie is one of the most recognized names in no-code app building, with a drag-and-drop platform for native Android and iOS apps. It pairs visual editing with AI-powered generation, so you can describe an app and get a functional starting point in minutes, with support for push notifications, in-app purchases, and GPS.

One caveat: Appy Pie has no permanent free plan, only a 7-day trial to build, customize, and preview. Publishing needs a paid subscription starting at $16/month per app for Android, with iOS on the Platinum plan at $60/month. We include it for its market presence, since the trial is enough to judge whether it fits before you commit. It is best for non-technical small business owners who want a native app published quickly.

Cons

• No permanent free plan, only a 7-day trial.

• Per-app pricing adds up for multiple projects.

• iOS publishing requires the Platinum plan ($60/month).

Top 10 Free App Builders and App Makers Compared

How to Choose the Right Free App Builder

After testing all 10, the lesson is simple: the best free app builder depends on your project, your skills, and where you want to end up. Each tool has a different sweet spot, so match it to what you actually need.

Which Free App Builder Fits Your Project?

Start with your main goal. That alone narrows the list fast.

• Absolute beginners and educators: to learn app logic at no cost, MIT App Inventor is a fantastic starting point. Its block-based system is built for education.

• Designers prioritizing UI: designers who live in Figma will like Bravo Studio for its pixel-perfect translation into a native app.

• Entrepreneurs building an MVP: Glide and Adalo offer fast cycles around databases and user flows. For full automation from a prompt, CatDoes ships an app and backend without a team.

• Developers seeking acceleration: FlutterFlow and Draftbit give you a visual environment plus custom code and full export.

• A quick native app, fast: Appy Pie lets you build, customize, and publish a native app after a 7-day trial.

What to Check Before You Commit

The free tier is a starting line, not the finish line. Before you pick one, ask yourself:

• Scalability: what happens when your app gets traction? Check the paid tiers of your top picks and make sure they fit your budget.

• Data and backend: where will your data live? Google AppSheet connects to your spreadsheets, while CatDoes generates and manages the backend for you. Know the ownership and export rules first.

• Learning curve: how much time can you spend? Thunkable is fast to learn, while FlutterFlow takes longer but offers more flexibility.

Frequently Asked Questions

Can you really build an app for free?

Yes, but with limits. Most free app builders let you design, build, and test at no cost, while publishing to the App Store or Google Play usually requires a paid plan. MIT App Inventor is an exception that allows free Android APK exports, and CatDoes lets you build and preview a complete app with a managed backend on its free tier.

What is the best free app builder for beginners?

For absolute beginners, MIT App Inventor offers the gentlest learning curve with block-based visual programming. If you want AI to do the heavy lifting, CatDoes generates the entire app from a text description, and Thunkable's AI Builder is another beginner-friendly option that creates native apps from prompts.

Can I publish to the App Store for free?

Generally no. Apple charges a $99/year developer fee regardless of the builder you use, and most platforms also require a paid subscription for App Store publishing. MIT App Inventor supports iOS builds with your own developer account, but most free app makers follow a "build free, pay to publish" model.

What is the difference between a PWA and a native app?

A Progressive Web App (PWA) runs in a mobile browser and can be added to a home screen, but it is not listed in the App Store or Play Store and has limited access to device hardware. A native app installs from an app store, has full access to device capabilities, and generally performs better. Glide builds PWAs, while CatDoes, FlutterFlow, and Thunkable produce native apps.

Do free app makers add branding to my app?

Most do. Adalo and Glide display platform branding on their free tiers, and removing it usually requires a paid plan. MIT App Inventor is a notable exception, as it is fully open-source with no branding requirements.
