Vision / Audio	VisionNode, AudioNode
Local LLMs	OllamaNode
REST APIs	HTTPRequestNode
Webhooks / GraphQL	WebhookNode, GraphQLNode
Custom Python logic	PythonCodeNode (most flexible)
Database CRUD	DataFlow auto-generated nodes (not raw DB nodes)
CSV / JSON / XML	CSVReaderNode, JSONParserNode, XMLParserNode
File read / write	FileReaderNode, FileWriterNode
Conditional routing	SwitchNode, IfElseNode
Loops / cycles	LoopNode, CycleNode
Logging / metrics	LoggerNode, MetricsNode

Critical Node Patterns

All nodes follow the canonical 4-parameter pattern from /01-core-sdk:

workflow.add_node("PythonCodeNode", "node1", {"code": "result = input_data * 2"})
workflow.add_connection("node1", "result", "node2", "input_data")

CRITICAL Gotchas

Rule	Why
NEVER use raw database nodes	Use DataFlow instead
ALWAYS use string-based node IDs	Variables cause issues
NEVER forget .build()	Required before execution
