Pros
  • Apache-2.0 open source with no vendor lock-in
  • Native gRPC, HTTP, and WebSocket support in one framework
  • Built-in dynamic batching, async, and Kubernetes orchestration
  • DocArray makes multimodal payloads (text, image, embeddings) first-class
  • Apache-2.0 licensed and pip-installable, runs fully self-hosted
  • Visual canvas plus Python escape hatch, no lock-in to a DSL
  • Built-in test cases and failure inspection, not an afterthought
  • Agents export as JSON so they diff cleanly in git
Cons
  • Steeper learning curve than FastAPI for simple endpoints
  • Less marketing focus now that Jina pushes hosted APIs
  • Executor/Flow abstractions can feel heavy for small projects
  • Managed cloud and official SDKs are still on the roadmap
  • Smaller ecosystem than LangGraph or LlamaIndex
  • Visual builders can hide complexity that bites at scale
