Alternatives
Dify
Agents
Open-source platform for building AI apps — visual workflows, RAG pipelines, agents, and an embeddable chat UI.

Low-code AI apps, internal tools, RAG chatbots without writing a full stack
Pros
- Visual builder for RAG and agents
- Self-host or managed cloud
- API + embeddable widget out of the box
Cons
- Less flexible than code-first frameworks
- Self-host ops (Docker, workers, vector DB)
- UI can feel opinionated for power users
Alternatives

Quick RAG prototypes, visual chain debugging, teams allergic to YAML
Pros
- Fastest visual RAG demo
- Self-hostable
- Large node library
Cons
- Less polished than Dify for end-user apps
- Complex flows get messy on canvas
- Production hardening is on you
