The best a0.dev alternative for web apps is StackMivo, an AI app builder that generates complete Laravel web applications with a real backend, admin panel, and database you own. a0.dev is excellent at what it's designed for: building mobile apps with React Native and Expo and publishing them to the App Store. But if your product is a SaaS dashboard, a client portal, or an internal tool, you need a web-first builder.
Picture a founder who builds a habit-tracking app with a0.dev over a weekend. It looks great on her phone and passes App Store review. Then her first B2B customer asks for a web dashboard for their HR team, complete with admin roles, CSV exports, and SSO. Her mobile builder wasn't designed for that.
That's when many people start searching for an a0.dev alternative (or type "a0 dev alternative" into Google). This guide covers what a0.dev does well, where web-first founders encounter its limitations, the best alternatives, and how to use both tools together if you need mobile and web.
Key Takeaways
a0.dev is a mobile-first AI app builder. It generates React Native apps with Expo (SDK 54 as of late 2025) and supports App Store publishing, payments, and analytics.
Its backend comes from Convex or Supabase, which works well for app data but isn't a full server-side framework for complex business logic.
StackMivo is the best a0.dev alternative for web apps. It generates full Laravel apps with Eloquent models, policies, Filament admin panels, and tests, deployable to Laravel Cloud, Forge, Ploi, or any SSH server.
You don't have to choose one. A Laravel API can serve both your web app and an a0.dev mobile frontend.
The founders featured in this article's examples are illustrative composites based on common scenarios.
What Is a0.dev, and What Does It Do Well?
a0.dev is an AI platform for building and shipping mobile apps. You describe your app in a chat, and its coding agent writes and edits the code in real time. According to a0.dev, the platform combines "AI-powered coding, one-click app publishing, integrated payments, and growth analytics."
Under the hood, a0 apps run on React Native and Expo. Its documentation states that "the latest a0 version uses Expo SDK 54" (a0 docs).
Here's where it shines:
App Store publishing. a0 handles the build, creates your App Store Connect listing, and uploads it for you. This removes one of the most painful steps in mobile development.
Payments and subscriptions for monetization, using Apple's in-app purchases on iOS and Stripe on the web. Android payments weren't supported at the time of writing.
Built-in AI APIs for inference and image generation within your app.
A backend in minutes through Convex or Supabase.
Testing on your phone with a0's own iOS and Android apps.
a0 reports more than 200,000 users and 300,000 apps created. For consumer mobile apps, it's one of the fastest ways to go from an idea to the App Store.
Why Founders Look for an a0.dev Alternative
The reasons usually come down to one thing: the product needs to be a web app first.
1. Web Is a Secondary Target
a0 lists web as a publishing target, and React Native code can run in the browser through Expo. However, the experience is designed around phones. Data-heavy web screens, such as wide tables, filters, bulk actions, and multi-column dashboards, present a different design challenge from mobile screens.
2. B2B Buyers Expect Web Features
If you sell to businesses, requests for admin roles, team management, audit logs, CSV exports, invoices, and an internal staff dashboard arrive quickly. These are standard features in web frameworks like Laravel and can be awkward to add to a mobile-first stack.
3. Business Logic Needs a Real Server
Convex and Supabase are strong backends for app data. However, complex logic, such as approval workflows, scheduled billing runs, PDF generation, third-party integrations, and background queues, is easier to build and test in a full server-side framework. Our guide to AI app builders with a full-stack backend explains why this matters as products grow.
Kemi founded a scheduling startup for physiotherapy clinics in Lagos. In March, she built the patient booking app with a0.dev, and it worked well. But clinic owners wanted a web dashboard for staff rotas, payouts, and reporting. After two weeks of trying to extend the mobile codebase, she generated a separate Laravel web app for the clinic dashboard. Her patients stayed on the mobile app, while clinics got the back office they were paying for.

If you're comparing a0.dev vs. StackMivo, the question is simple: Is your main product something people use on their phones or something businesses use at a desk?
Other a0.dev Alternatives Worth Considering
Lovable and Bolt.new
Both generate JavaScript apps from prompts, primarily using React, and both now include built-in backends for data and authentication. Bolt can also build Expo mobile apps, making it the closest like-for-like a0.dev alternative. They're quick for prototypes, but their backends remain JavaScript-based and platform-hosted. For PHP teams, see our Bolt.new alternative for Laravel guide and our Lovable vs. StackMivo comparison.
v0
Vercel's v0 builds full-stack Next.js apps with database integrations such as Neon and Supabase. It's especially strong at polished React interfaces. If you want your backend in Laravel rather than Next.js, our v0 alternative for full-stack Laravel post compares the two.
Staying on a0.dev
If your product is genuinely mobile-first and consumer-facing, a0.dev may still be the right tool. Keep using it for the app, and add a web back office when customers need one.
Use Both: Laravel Backend, a0.dev Mobile App
Many products need both a phone app and a web app. The cleanest architecture is a single Laravel backend serving both:
Generate the Laravel app with your data model, admin panel, and web screens.
Expose a versioned REST API using Laravel Sanctum tokens for mobile clients. Our Laravel mobile app backend guide covers tokens, API Resources, and pagination.
Point your a0.dev app at that API instead of using a separate Convex or Supabase backend, so the web and mobile apps share the same users, data, and business rules.
Send push notifications from Laravel queues so the backend controls when users are notified. a0's built-in push runs through Convex, so plan to call Expo's push service from Laravel instead.
Daniel runs a two-person agency in Cape Town. In August, a fitness studio client wanted a member app and a staff web portal. He generated the Laravel backend and staff portal first, then built the member app in a0.dev against the Laravel API. Using one database and one set of business rules meant class bookings and payments matched across both platforms from day one.

Can a0.dev build web apps?
a0.dev lists web as a publishing target because its React Native and Expo apps can run in a browser. However, it's designed for mobile-first development, so complex web dashboards and admin tools are often a better fit for a web framework.
What framework does a0.dev use?
a0.dev builds apps with React Native and Expo. Its documentation states that the latest version uses Expo SDK 54.
Can I use a0.dev with a Laravel backend?
Yes. Build a versioned REST API in Laravel with Sanctum authentication, then have your a0.dev app call it. Your web and mobile apps can then share one backend.
Is a0.dev free?
a0.dev offers a free way to get started and paid plans for additional usage and publishing features. Check the a0.dev pricing page for current plans, as third-party listings report different figures.
The Bottom Line
a0.dev is a great tool for getting a mobile app into the App Store quickly. But not every product is a phone app. If your customers work at a desk, need admin roles, reports, and integrations, or your business logic is outgrowing a hosted backend, you need a web-first builder.
Choose the a0.dev alternative that matches your product. For web apps with a real backend, that's StackMivo. You can still use a0.dev for the mobile side.
