Is there an open-source alternative with features similar to Rasa CALM? Specifically, one that allows you to design conversational flows in a similar manner while offering high customizability?

The closest option I’ve found is [GitHub - NVIDIA/NeMo-Guardrails: NeMo Guardrails is an open-source toolkit for easily adding programmable guardrails to LLM-based conversational systems.](https://github.com/NVIDIA/NeMo-Guardrails)
