"slow is smooth, and smooth is fast"

laminar is the workflow framework that works for you. It aims to be a modern container first framework that enables you to rapidly go from local development into production as quickly as possible.

• Easy to write, container first, cloud first
• Configureable statically at definition time and dynamically at runtime
• Fully definined in Python and fully typed
• Easily testable
• Foreach fanouts
• Composable workflows
• Conditional branching
• No AST introspection, shared global state, or function hijacking magic

# main.py
from laminar import Flow, Layer

# Declare the Flow
class HelloFlow(Flow): ...

# Register Layers
@HelloFlow.register
class Hello(Layer):
    def __call__(self) -> None:
        self.value = "hello"

# Register a Layer dependency
@HelloFlow.register
class World(Layer):
    def __call__(self, hello: Hello) -> None:
        print(f"{hello.value} world")

# Execute the Flow
if flow := HelloFlow():
    flow()

python main.py
>>> "hello world"
