Comparisons overview
If you’re evaluating open-source form and survey tools, you’re probably weighing some of these. Short version of where Forms-Engine sits, then the honest table — each linked page includes where the alternative is the better choice, because it sometimes is.
Forms-Engine’s particular combination: the visual editor, backend, and embeddable renderer are all MIT-licensed and all self-hosted — no commercially licensed builder, no hosted service in the loop — with version-pinned responses, a rules engine with pinned semantics, and answers landing as flat typed JSON in your own MongoDB. The trade-off is equally plain: it’s a young project with a small ecosystem, a deliberately scoped feature set, and no hosted option for teams who don’t want to run infrastructure.
| Forms-Engine | SurveyJS | Formbricks | Form.io | Typeform / Jotform | |

| Backend included | ✅ (Spring Boot + MongoDB) | ❌ bring your own | ✅ | ✅ (Node + MongoDB) | ✅ (theirs) |
| Your database | ✅ your MongoDB | ✅ (whatever you build) | ✅ if self-hosted | ✅ if self-hosted | ❌ |

How to choose in one paragraph each
Section titled “How to choose in one paragraph each”Choose SurveyJS when you’re building form UX deep inside your own product across React/Angular/Vue and want the richest client-side form library — and either don’t need a visual builder or can license theirs.
Choose Formbricks when what you actually want is surveys and experience management — in-app micro-surveys, targeting, analytics — rather than embeddable data-collection forms.
Choose Form.io when forms are one part of a larger form-and-data platform need — user auth, roles, submission workflows — and you have the budget for the enterprise tier where much of that lives.
Choose Typeform or Jotform when you don’t want to run anything — hosted, polished, template-rich, and the data living on someone else’s servers is acceptable.
Choose Forms-Engine when you want the whole loop — build visually, embed natively, own the data — under one permissive license on your own infrastructure, and you’re comfortable with a young project whose limitations are documented rather than discovered.
