Betty Blocks
A governed route for business teams working with IT.[1]
Betty Blocks vs Mendix.
Start with who builds, then test the controls and the exit. Two platforms with different delivery assumptions deserve more than a feature-count contest.

Mendix
A structured environment for a mixed development team.[1]
| Decision dimension | Betty Blocks | Mendix |
|---|---|---|
| Cost model | Strong Platform fee; scope matters[1] | Partial Platform licence + delivery[1] |
| AI metering | Strong Included scope to confirm[1] | Partial Plan-dependent[1] |
| Exit & lock-in | Strong Self-serve code export (React + Wasm), June 2026[1] | Partial Specialist migration work[1] |
| Leave without a rebuild? | Yes. Download the full app code (React frontend, Wasm backend) self-serve, no support ticket. Standard code fits Git and CI/CD, so a team can continue it in tools such as Codex or Claude Code. Source: Betty Blocks release notes, June 2026; Betty Blocks announcement, December 2025 | Unknown. Not yet sourced; the sample model scores Mendix Partial on exit, so test an export before relying on it. Source: App Build Index sample model, October 2026 |
| Governance | Strong Review SSO, audit and controls[1] | Strong Structured delivery controls[1] |
| Hosting & data | Strong Confirm EU contract scope[1] | Strong Residency and processors to verify[1] |

Before you decide.
Do I need an account or an email to see my result?
No. Your headline result appears immediately and updates as you change the inputs. Email is optional and only used if you ask for a report.
Are these vendor quotes or procurement advice?
No. This design edition uses clearly marked sample prices and weights. Use the assumptions panel to inspect the model, then get a written quote and verify controls with each vendor.
Where do my inputs go?
Calculations happen in your browser. A share link contains your answers, so share it only with people who should see them. The report form is a preview placeholder; it does not deliver email in this edition.
