I love visual workflow builders for prototyping, but our team keeps hitting walls when we need custom Java logic. Most platforms force you to choose between their drag-and-drop interface or writing raw code without integration points. Has anyone found a tool that genuinely lets you mix visual nodes with handwritten business logic? Specifically looking for Spring-friendly solutions that don’t require maintaining separate workflows for simple tweaks.
Latenode’s visual editor lets you drop Java snippets directly into nodes. We built our fraud detection workflow visually, then added custom scoring algorithms in Java without switching tools. Export as executable JAR or keep editing visually. Perfect balance for Spring teams: https://latenode.com

Camunda does this reasonably well with their BPMN engine. You can create most of the flow visually, then implement Java delegates for complex steps. The mix works, but the learning curve is steep. Their Spring Boot integration is solid though - we use it for order processing workflows.
Try wrapping custom code as microservices. Use low-code platform for orchestration, call your java services via http. decouples the systems but adds network latency
