Full Comparison

Criterion	AppSheet	Mendix
Starting price	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.	lower value Free tier; Standard from $1,090 / month The Standard tier is $1,090 / month for a One App plan and $2,725 / month for Unlimited Apps. Cloud resources are charged on top of the subscription in both cases. Premium is quoted by the vendor.
Free trial	Free plan with full platform access for prototyping with up to 10 test users, with no time limit stated	Free tier with no commitment and no credit card required
Output	Mobile and web business apps plus automations such as email, SMS and push notifications	Enterprise web and mobile applications and AI agents, built as visual models executed by the Mendix Runtime
API	Yes, a REST API for reading and writing table records in an app	Yes, apps publish REST services with OpenAPI documentation and OData or GraphQL services
Hosting	Google cloud	Mendix Cloud on AWS, Mendix on Kubernetes, Mendix on Azure, SAP Business Technology Platform, private cloud or on-premise
What it generates	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	Enterprise web and mobile applications, AI agents and orchestrated processes. Maia is the agentic AI built into the platform, and Maia Make executes multi-step development autonomously from requirements to working software, generating into visual models rather than raw code
Stack and frameworks	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	An application model built in Studio Pro and executed by the Mendix Runtime, not a generated source tree. Custom logic is added through Java Actions and JavaScript Actions
Auth and database	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	Apps deployed to Mendix Cloud run on PostgreSQL and cannot be configured to use another database; self-managed deployments support MySQL and MariaDB, Oracle, SAP HANA and SQL Server
Hosting and deploy	Google cloud only, with apps published to end users rather than deployed to infrastructure; there is no self-hosted option	Mendix Cloud on AWS in multiple regions, with at least an acceptance and a production environment per licensed node and daily backups kept up to a year depending on the plan. Also Mendix on Kubernetes, Mendix on Azure, SAP BTP, private cloud and on-premise. Free apps sleep after roughly an hour of inactivity, run a single instance and get 0.5 GiB of database storage
Payments	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	No payment handling in the platform itself. A provider is added from the Marketplace, where Mendix publishes a Stripe Checkout Connector and partners publish further Stripe and Adyen integrations
Access to the code	Apps live in AppSheet rather than as an exportable codebase; Apps Script and the REST API are the extension points	The artefact is a visual application model rather than a repository of hand-written source; custom Java and JavaScript enter as Java Actions and JavaScript Actions
Deployment	Cloud (SaaS), Browser-based	more entries Cloud (SaaS), Browser-based, On-premise
Support	Email helpdesk	more entries Email helpdesk, Phone, Community forum
Onboarding	Documentation and knowledge base	more entries Documentation and knowledge base, Live online demos and webinars, On-site training
Company size	more entries Small and mid-sized, Enterprise	Enterprise
Integrations	more entries Google Sheets, Google Drive, Google Apps Script, BigQuery, Cloud SQL, Microsoft 365, Azure SQL, Salesforce, Dropbox, Smartsheet, OData, Apigee	AWS, SAP, Siemens Teamcenter, Stripe

The trade-offs

Strengths and Limitations

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

Mendix

Strengths

Free tier with unlimited users and one environment per app, no credit card and no commitment
Runs on public cloud, private cloud, Kubernetes or on-premise, unlike most tools in this category
Bring your own LLM, whether frontier, open-source or private, and connect existing data without migrating it
Apps publish REST with OpenAPI documentation as well as OData and GraphQL services
Backed by Siemens and named a Gartner Magic Quadrant Leader for enterprise low-code nine years running

Limitations

The step from the free tier to Standard is $1,090 / month, with no small paid plan in between
Cloud resources are billed on top of the subscription, so the listed price is not the total
Standard support runs 9 AM to 5 PM with a 99.5 percent uptime guarantee; 24/7 support, high availability and multi-region failover need the quoted Premium tier
Free apps sleep after about an hour of inactivity and are capped at 0.5 GiB of database storage
Apps deployed to Mendix Cloud are locked to PostgreSQL
