Full Comparison

Criterion	a0.dev	AppSheet
Starting price	Not stated	Free for prototyping; paid plans from $5 / user / month Starter $5, Core $10 and Enterprise Plus $20 per user per month. Core is included with most paid Google Workspace plans. Publisher Pro is priced per app instead, at $50 per app per month, and serves unlimited users.
Free trial	Not stated	Free plan with full platform access for prototyping with up to 10 test users, with no time limit stated
Output	Native iOS and Android apps (React Native), plus web	Mobile and web business apps plus automations such as email, SMS and push notifications
API	Yes	Yes, a REST API for reading and writing table records in an app
Hosting	Not stated	Google cloud
What it generates	Native mobile apps for iOS and Android (plus web), from a prompt	Mobile and web business apps for work such as operations, field work, HR, sales and project management, plus automations sending email, SMS and push notifications; Gemini for App Creation generates the app from a described business process, proposing tables and columns before building
Stack and frameworks	React Native	No-code throughout: apps are configured in AppSheet's editor rather than written in a framework, and logic is extended with Google Apps Script functions and the REST API
Auth and database	Managed backend with a choice of Convex or Supabase for the database, plus built-in push notifications	Runs on existing data rather than its own: Google Sheets and Drive, Microsoft 365 and hosted Excel, Cloud SQL, Azure SQL, BigQuery, Salesforce, Dropbox, Smartsheet, OData, Apigee and REST APIs, with an AppSheet database included. Row limits per database scale with the plan, from 5 databases of 2,500 rows on Starter to 200 databases of 200,000 rows on Enterprise Plus. Enterprise data service connections and the stronger security, team management and governance controls are Enterprise Plus, which needs a Google Workspace administrator account
Hosting and deploy	One-click publishing to the App Store and Google Play (IPA/APK), with a web preview	Google cloud only, with apps published to end users rather than deployed to infrastructure; there is no self-hosted option
Payments	Built-in monetization: subscriptions and one-time purchases via the App Store	No built-in payments. No payment provider appears among the external services AppSheet documents, so a provider has to be reached like any other API, through a REST data source or a webhook step in an automation
Access to the code	Projects are built on Expo and edited by the agent inside a0's own workspace. The documentation covers runtime and Expo SDK upgrades, over-the-air updates and store publishing, and documents no source-code download, GitHub sync or local development	Apps live in AppSheet rather than as an exportable codebase; Apps Script and the REST API are the extension points
Deployment	Cloud (SaaS), Browser-based	Cloud (SaaS), Browser-based
Support	Community forum	Email helpdesk
Onboarding	Documentation and knowledge base	Documentation and knowledge base
Company size	Freelancers, Small and mid-sized	Small and mid-sized, Enterprise
Integrations	Convex, Supabase, App Store Connect, Google Play, Firebase Cloud Messaging	more entries Google Sheets, Google Drive, Google Apps Script, BigQuery, Cloud SQL, Microsoft 365, Azure SQL, Salesforce, Dropbox, Smartsheet, OData, Apigee

The trade-offs

Strengths and Limitations

a0.dev

Strengths

Generates a full React Native app and publishes it to the App Store and Google Play
Built-in monetization with subscriptions and one-time purchases
Convex backend and push notifications wired in

Limitations

Primarily a mobile app builder: it generates native iOS and Android apps, with web as a secondary target
Output is React Native on Expo, so you work within that stack rather than a framework of your choice

AppSheet

Strengths

Gemini app creation is included in every paid licence rather than charged separately
Starts from data a company already keeps, including non-Google sources such as Microsoft 365, Azure SQL and Salesforce
Core is bundled with most paid Google Workspace plans, so many organisations already hold the licence
Free tier has full platform access for prototyping with no stated time limit

Limitations

Google cloud only, with no self-hosted option
Apps are not an exportable codebase, so leaving the platform means rebuilding
Enterprise data connections, machine learning modelling and the governance controls are Enterprise Plus only, and need a Workspace administrator account
Database row limits are tied to the plan, so heavier data pushes the tier up
