| Criterion | Budibase | Mendix |
|---|---|---|
| Starting price | Free self-hosted; cloud from $19 / month Cloud on annual billing: Pro $19, Premium $49 and Business $299 per month. On monthly billing that becomes $22.80, $58.80 and $358.80. Extra creators $50 and end users $5 per month. Enterprise on request. | 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 self-hosted open-source edition | Free tier with no commitment and no credit card required |
| Output | Internal apps, forms, automations and AI agents | Enterprise web and mobile applications and AI agents, built as visual models executed by the Mendix Runtime |
| API | Not stated | Yes, apps publish REST services with OpenAPI documentation and OData or GraphQL services |
| Hosting | Budibase cloud or self-hosted (Docker, Kubernetes, DigitalOcean, Portainer) | Mendix Cloud on AWS, Mendix on Kubernetes, Mendix on Azure, SAP Business Technology Platform, private cloud or on-premise |
| What it generates | Internal operations: forms, approvals, task routing and admin tools, plus automations and AI agents that act across connected systems | 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 | Visual builder with automations; AI generates JavaScript bindings, cron expressions and table schemas from a written description rather than building a whole app from a prompt | 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 | Internal BudibaseDB built on CouchDB, plus external SQL databases such as PostgreSQL and Microsoft SQL Server, REST APIs and custom datasource plugins; app users sign in with OpenID Connect or Google | 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 | Budibase cloud, or self-hosted with Docker, Docker Compose, Kubernetes, DigitalOcean or Portainer | 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; a payment provider is reached through a REST datasource like any other API | 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 | Open source: GPL v3 core, MPL client and component libraries so apps built with it can carry their own licence, and a Business Source Licence on the paid features | 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, On-premise | Cloud (SaaS), Browser-based, On-premise |
| Support | Email helpdesk, Community forum | 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 PostgreSQL, Microsoft SQL Server, REST API, Slack, Microsoft Teams, Discord, OpenAI, Anthropic, Google, Mistral, OpenRouter, Groq | AWS, SAP, Siemens Teamcenter, Stripe |
