a0.dev
a0.dev (Build and publish native mobile apps by chatting with AI, with payments, publishing and analytics built in) **a0.
dev** is an AI mobile app builder that turns plain-English prompts into native React Native apps, then helps you publish them to the App Store and Google Play. An AI coding agent writes and edits your app in real time while you chat, and a one-click publish flow handles the build, creates the App Store Connect listing, and uploads the app for you. What sets a0.dev apart from most AI builders is how much of the "ship a real app" path it covers: built-in payments and subscriptions, AI inference and image-generation APIs, a database through Convex or Supabase, a growth-analytics dashboard, and a companion mobile app (iOS and Android) so you can test, edit, and deploy from your phone. It is backed by Y Combinator (W25 batch) and operated by TeeHee Tech LLC.
This page covers what a0.dev is, how it works, pricing, honest reviews, and how it compares with other native-app builders like Rork.
Overview
What is a0.dev?
a0.dev is a cloud-based AI app builder focused on native mobile apps. You describe the app you want, and an AI coding agent generates a React Native app, editing it live as you refine your idea in chat. Unlike web-first "vibe coding" tools, a0.dev is built end to end for the mobile use case: it does not just generate code, it also handles the parts that usually stop non-developers from actually shipping, namely building the binary, creating the store listing, wiring up payments, and tracking growth. It is aimed at founders, indie makers, and small teams who want a real app in the App Store or Google Play without hiring engineers.
The platform bundles an AI coding agent, a database layer through Convex or Supabase, built-in APIs for AI inference and image generation, one-click publishing, in-app payments and subscriptions, and an analytics dashboard. There is also a companion a0.dev app on both iOS and Android that lets you test, edit, and deploy your projects from your phone, which is unusual in this category.

How a0.dev works
You start in the browser or the a0.dev app and describe your idea. The AI agent scaffolds the screens, navigation, and logic, and keeps editing in real time as you chat to refine it. You add a database through Convex or Supabase, drop in AI features using the built-in inference and image-generation APIs, and set up payments and subscriptions without leaving the platform. When the app is ready, a0.dev's one-click publish flow builds it, creates the App Store Connect listing, and uploads it, so you are not manually wrestling with Xcode, certificates, and provisioning. As with any App Store submission, you still need an Apple Developer Program account (99 US dollars a year, paid to Apple), and Google Play has a one-time 25 US dollars registration fee.
Key a0.dev features
a0.dev tries to cover the whole journey from prompt to a live, revenue-ready app. These are the pieces that matter most.
- AI coding agent: writes and edits your React Native app in real time as you chat.
- One-click publishing: handles the build, creates the App Store Connect listing, and uploads the app.
- Built-in payments and subscriptions: monetise your app without bolting on a separate billing stack.
- AI inference and image APIs: add chat, vision, and image generation to the apps you build.
- Database via Convex or Supabase: real data storage with a choice of backend.
- Companion mobile app and analytics: test and deploy from your phone, and track users, subscriptions, and performance.
a0.dev pricing
a0.dev is freemium and credit-based. There is a free tier that lets you build and test a project so you can try the tool. The main paid plan, Pro, has been cited at around 20 US dollars a month with unlimited app builds and the ability to submit to TestFlight, with a monthly allowance of credits for the AI work. A higher Max tier has been cited at around 200 US dollars a month for heavier usage. Because the AI agent works by consuming credits, how much you actually spend depends on how much building and debugging your app needs. Prices and credit allowances change, so confirm the current tiers on a0.dev before subscribing, and remember the separate Apple and Google developer fees if you plan to publish.
a0.dev reviews: the honest picture
Reviewers are positive about a0.dev for exactly what it is designed to do and clear about where it falls short. On the plus side, it is rated well (Build Fast with AI scored it around 4.3 out of 5), and reviewers say it is one of the faster ways to get a native mobile app built and submitted, with the built-in payments and one-click publishing singled out as genuinely useful. The honest caveats: a0.dev does not build web apps, so it is the wrong tool if that is what you need; it is credit-based, so heavy iteration and debugging raise the cost; and apps with complex custom backends or unusual requirements will still need developer help. The fair summary is that a0.dev is a strong pick when your goal is a monetisable native mobile app shipped quickly, and a poor fit for web projects or deeply custom systems.

a0.dev vs Rork
a0.dev and Rork are the two AI builders most focused on native mobile apps, so they compete directly. Both turn prompts into React Native apps and both can publish to the stores. The difference is emphasis. a0.dev leans into the full "ship and earn" path, with built-in payments and subscriptions, one-click App Store Connect publishing, and a growth-analytics dashboard, which suits makers who want to monetise quickly. Rork offers a cross-platform Pro plan and a native SwiftUI Max plan, plus its own backend, AI cloud, games, and an AI App Store reviewer, which gives more range on the build side. Both are credit-based and both can get pricey with heavy iteration. If monetisation and the fastest publish path matter most, a0.dev is compelling; if you want native SwiftUI output or a broader build toolkit, Rork is worth a look. The table sums it up.
Who should use a0.dev
a0.dev suits non-technical founders who want a monetisable mobile app in the stores without hiring developers, indie hackers shipping and testing app ideas fast, and small teams building simple native products. It is not for web apps, which it does not make, and it is not the right home for performance-critical or heavily custom systems that need a full engineering stack. For a fast path from idea to a paid, published mobile app, it is one of the stronger options in the category.
History
a0.dev was founded in 2024 in United States by TeeHee Tech LLC (Company behind a0.dev).

Frequently asked questions
- What is a0.dev?
- a0.dev is an AI mobile app builder that turns plain-English prompts into native React Native apps and helps you publish them to the App Store and Google Play. An AI coding agent writes and edits the app in real time as you chat, and the platform includes one-click publishing, built-in payments and subscriptions, AI and image-generation APIs, a database through Convex or Supabase, and an analytics dashboard. It is backed by Y Combinator (W25) and operated by TeeHee Tech LLC.
- How much does a0.dev cost?
- a0.dev is freemium and credit-based. There is a free tier to build and test a project. The main paid plan, Pro, has been cited at around 20 US dollars a month with unlimited app builds and TestFlight submission, and a higher Max tier at around 200 US dollars a month for heavier usage. Because the AI works by consuming credits, your real cost depends on how much building and debugging you do. Confirm current pricing on a0.dev, and budget the separate Apple (99 US dollars a year) and Google Play (25 US dollars one-time) developer fees to publish.
- Is a0.dev good? What do reviews say?
- Reviews are positive for its intended use. Build Fast with AI rated it around 4.3 out of 5, and reviewers highlight how fast it gets a native app built and submitted, with built-in payments and one-click publishing called out as useful. The honest caveats are that a0.dev does not build web apps, that it is credit-based so heavy iteration costs more, and that complex custom backends still need a developer. It is strong for shipping a monetisable native app quickly and weak for web or deeply custom projects.
- Does a0.dev build real native apps?
- Yes. a0.dev generates native React Native apps, not web apps, and its one-click publish flow builds the binary, creates the App Store Connect listing, and uploads it for you. It also offers a database through Convex or Supabase and built-in payments, so the apps it produces can store data and earn revenue. This native-mobile focus is its main differentiator from web-first AI builders.
- Does a0.dev have a mobile app?
- Yes. In addition to the web experience, a0.dev has a companion app on both iOS and Android that lets you test, edit, and deploy your projects from your phone. This is relatively unusual among AI app builders and is handy for reviewing changes or shipping updates when you are away from your computer.
- Can a0.dev build web apps?
- No. a0.dev is focused on native mobile apps for iOS and Android and does not build web apps. If you need a web product, dashboard, or landing page, a web-first tool like Lovable or Base44 is a better fit. a0.dev is the right choice specifically when your deliverable is a mobile app for the app stores.
- a0.dev vs Rork: which should I use?
- Both are AI builders focused on native mobile apps built with React Native, and both publish to the stores. a0.dev leans into monetisation and the fastest publish path, with built-in payments, subscriptions, one-click App Store Connect publishing, and analytics. Rork offers a cross-platform Pro plan and a native SwiftUI Max plan plus its own backend, AI cloud, games, and an AI App Store reviewer, and it also builds web apps. Pick a0.dev to monetise and ship fast, and Rork for native SwiftUI output or a broader build toolkit.
- Who is behind a0.dev?
- a0.dev is operated by TeeHee Tech LLC and is a Y Combinator company from the Winter 2025 (W25) batch. The founders are not prominently named on the public site, but the Y Combinator backing and the company entity are confirmed. It is part of a competitive wave of AI app builders aiming to get non-developers from an idea to a published app.
- How do I publish an app made with a0.dev?
- a0.dev is designed to minimise the publishing friction. Its one-click flow builds your app, creates the App Store Connect listing, and uploads it, so you avoid most of the manual Xcode and certificate work. You still need an Apple Developer Program membership, which is 99 US dollars a year paid to Apple, and Google Play charges a one-time 25 US dollars developer registration fee. a0.dev also supports TestFlight submission on its paid plan for beta testing before launch.
- What are the best a0.dev alternatives?
- For native mobile apps, the closest alternative is Rork, which also builds React Native apps and adds native SwiftUI output. For web apps, which a0.dev does not make, the main options are Base44 (an all-in-one builder that is now a Wix company) and Lovable (React and Tailwind with GitHub export). Choose based on your target: a0.dev or Rork for mobile apps, and Base44 or Lovable for web apps.
