Full Comparison
| Criterion | Mendix | WeWeb |
|---|---|---|
| Starting price | 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 plan; paid seat and hosting plans are priced separately Pricing is split in two. A seat plan (Free, Essential, Pro, Partner) controls editor access, AI tokens, code export and MCP access; a hosting plan (Free, Launch, Grow, Scale) covers WeWeb-hosted deployments, with limits on bandwidth, storage and app sessions. A seat plan is required before a hosting plan can be added, and self-hosted apps have no session limit. |
| Free trial | Free tier with no commitment and no credit card required | Free plan with the visual editor, WeWeb-hosted deployment with a session limit and a monthly AI token allowance |
| Output | Enterprise web and mobile applications and AI agents, built as visual models executed by the Mendix Runtime | Vue.js single-page web apps, hosted by WeWeb or exported and self-hosted |
| API | Yes, apps publish REST services with OpenAPI documentation and OData or GraphQL services | Not stated |
| Hosting | Mendix Cloud on AWS, Mendix on Kubernetes, Mendix on Azure, SAP Business Technology Platform, private cloud or on-premise | WeWeb cloud on AWS, or self-hosted after code export |
| What it generates | 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 | Production web apps such as SaaS products, customer portals, internal tools, directories and MVPs, built visually or generated from a description by the WeWeb AI assistant |
| Stack and frameworks | 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 | Vue.js single-page applications, editable visually or extended with coded components |
| Auth and database | 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 | Supabase, Xano, Airtable, Algolia, SmartSuite and any REST API, with internal databases connected without replication; auth through Supabase Auth, Xano Auth, Auth0, OpenID, custom tokens or WeWeb Auth |
| Hosting and deploy | 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 | WeWeb cloud hosting on AWS, or self-hosting anywhere after code export, with a documented Cloudflare route |
| Payments | 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 | Yes, a Stripe plugin among the documented extensions |
| Access to the code | 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 | Yes, full Vue.js code export and self-hosting from the Essential seat plan upwards |
| MCP-ready | No | stated Yes |
| Deployment | Cloud (SaaS), Browser-based, On-premise | Cloud (SaaS), Browser-based, On-premise |
| Support | more entries Email helpdesk, Phone, Community forum | Chat, Community forum |
| Onboarding | more entries Documentation and knowledge base, Live online demos and webinars, On-site training | Documentation and knowledge base |
| Company size | Enterprise | more entries Freelancers, Small and mid-sized, Enterprise |
| Integrations | AWS, SAP, Siemens Teamcenter, Stripe | more entries Supabase, Xano, Airtable, Algolia, SmartSuite, Stripe |

The trade-offs
Strengths and Limitations
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
WeWeb
Strengths
- Exports the generated Vue.js source, so an app can be self-hosted and is not locked to the platform
- Connects to Supabase, Xano, Airtable, Algolia, SmartSuite and any REST API, including internal databases without replication
- Six documented authentication routes, from Supabase Auth and Auth0 to a custom token flow
- Official MCP server, so outside agents such as Claude, Cursor or ChatGPT can build inside a project
Limitations
- Seat plan and hosting plan are billed separately, so the cost of a project depends on both
- Code export and self-hosting require at least the Essential seat plan
- MCP access needs a Pro or Partner plan once the 14-day trial on a new workspace ends
- The MCP server does not expose plugin actions, so an agent cannot build with the Xano or Supabase plugins
- It builds the front end and expects a backend such as Supabase or Xano alongside it
Plans
Pricing
Mendix
- Free $0 No hidden fees, no commitment, no credit card. Full platform access for exploration, prototypes and small applications, unlimited users, one deployment environment per app.
