Coming from another tool

Each page has a scaffold (the pyrula init flag that writes a runnable app.py in that tool’s shape), a concept map with a change label per row, and an example that runs offline.

Page	Scaffold
Coming from Pydantic AI	pyrula init --pydantic-ai
Coming from LangGraph	pyrula init --langgraph
Coming from Celery	pyrula init --celery
Coming from Temporal	none
Coming from FastAPI	pyrula init --fastapi

The change labels in the concept maps:

Label	Meaning
Direct swap	Same concept, a different name or import.
Small rewrite	Same idea, a few lines change shape.
Conceptual redesign	The idea maps to a different Pyrula mechanism.
Operational change	The code stays; how you run, deploy or watch it changes.
Not supported	Pyrula has no equivalent today.
