Glassly, Rork, a0.dev, Vibecode, FlutterFlow and Replit offer routes to mobile apps, but their editing, preview and publishing workflows differ. Choose by the work your project needs and the setup you are willing to manage. Using Expo does not, by itself, mean a product requires coding knowledge.
This comparison is written by Glassly. We checked the linked provider documentation on 24 September 2026; it is a feature comparison, not a hands-on speed or quality benchmark. Product plans and publishing support can change, so check the linked instructions before buying.
Rork: check which project type you are choosing
Rork supports describing an app in plain English. Its docs say new projects can no longer be Expo (React Native): new Rork apps are native Swift for iPhone and Kotlin for Android, as two codebases. Its free plan covers designing only, and building needs Rork Pro at $20 a month. It builds on its own machines, uploads to App Store Connect, can send Android builds to Google Play’s internal testing, and documents a managed backend and GitHub export on paid plans. Our Glassly vs Rork page sets the two side by side.
If you are looking for a Rork alternative, compare the complete workflow for the same app: backend setup, a real device build, changes after the first version and export. Both Rork and Glassly support building through natural-language requests.
a0.dev: native builds and an App Store workflow
a0 documents IPA and APK generation for native device testing, and a separate iOS submission flow that connects your Apple account and sends a build to App Store Connect. Its push documentation describes a Convex backend with a0 notification delivery. It is inaccurate to describe this as simply generating screens and leaving all backend work to you. Check the current Android store-release instructions separately from downloading an APK.
Vibecode: build on iPhone or in a browser
Vibecode's FAQ describes an iOS builder and a web builder, with React Native/Expo output for iOS and Android. That is different from having a released Android version of the builder itself. It also documents Vibecode Cloud for database, authentication and storage, plus source-code download. Its publishing guide includes an App Store flow through Expo Launch, requiring your Apple membership and an Expo account. Check deployment allowances and charges as well as generation credits.
FlutterFlow: visual editing with Flutter output
FlutterFlow is a visual app builder with AI features and Flutter code output. Its plan comparison covers downloading code, APK builds and store deployment. Check which subscription includes the export and deployment features you need. If you want a FlutterFlow alternative, decide whether you prefer editing screens and actions visually or describing changes in chat. Code ownership and export matter in either workflow; Glassly also exports code.
Replit: an agent, development tools and backend services
Replit's native mobile documentation describes React Native/Expo apps, cloud simulator and emulator previews, Expo Go device previews, built-in backend services and guided TestFlight/App Store submission. Its docs say publishing to Google Play is not yet supported. Replit and Expo handle iOS builds in the cloud, so a local Mac is not required. Consider it if you want access to development tools alongside an AI-driven workflow.
Glassly: start from a template and ask for changes
Glassly starts with a free app template or, on a paid plan, your own description, includes a managed starter backend, and compiles and signs iOS and Android builds on its own machines. Changes are requested in chat. You can download the Expo source project free, including on the free plan. The workflow guide shows the creation, testing and installation steps.
For iPhone installs through Glassly, connect your own Apple developer account (standard fee $99/year, paid to Apple). Android installs from a link, subject to device permissions and developer verification. Publishing on Google Play needs your own developer account ($25 once, paid to Google). Your own Supabase project is required for production or store builds, integration secrets, and apps that outgrow the starter limits. Each template has a defined feature set; additional requests need testing and may need external services.
Compare the total work and cost
Vibe coding for mobile apps describes asking AI to write an app. It does not establish which builder will fit your project. Use the same brief with each candidate: create an account inside the app, save and reopen data, test two user roles, install on each target platform, and export if you need a handover. A preview inside a companion app and a standalone install are different milestones.
On Glassly, standard templates use no credits (premium ones cost credits to claim) and new accounts receive 5 credits to try changes. Basic is $5 a month with 50 credits, Pro is $19 a month with 250 credits, Business is $49 a month with 1000 credits. Compare our pricing and limits with each provider's current plan, backend and deployment costs. No single tool is best for every app; hardware integrations, complex permissions and specialist requirements may need a developer whichever builder you choose.
