✨ What is Railtracks?

Easy agent building, for no one but YOU: Create deployable complex agents using simple, Pythonic style interface with natural control flow.

import railtracks as rt

# Define a tool (just a function!)
def get_weather(location: str) -> str:
    return f"It's sunny in {location}!"

# Create an agent with tools
agent = rt.agent_node(
    "Weather Assistant",
    tool_nodes=(rt.function_node(get_weather)),
    llm=rt.llm.OpenAILLM("gpt-4o"),
    system_message="You help users with weather information."
)

# Run it
flow = rt.Flow(name="Weather Flow", entry_point=agent)
result = await flow.invoke("What's the weather in Paris?")
print(result.text)  # "Based on the current data, it's sunny in Paris!"

That's it. No complex configurations, no learning proprietary syntax. Just Python.

🎯 Why Railtracks?

🐍 Pure Python Experience # Write agents like regular functions @rt.function_node def my_tool(text: str) -> str: return process(text) ✅ No YAML, no DSLs, no magic strings ✅ Use your existing debugging tools ✅ IDE autocomplete & type checking	🔧 Tool-First Architecture # Any function becomes a tool agent = rt.agent_node( "Assistant", tool_nodes=(my_tool, api_call) ) ✅ Instant function-to-tool conversion ✅ Seamless API/database integration ✅ MCP protocol support
⚡ Look Familiar? # Smart parallelization built-in # with interface similar to asyncio result = await rt.call(agent, query) ✅ Easy to learn standardized interface ✅ Built-in validation, error handling & retries ✅ Auto-parallelization management	👁️ Transparent by Design railtracks viz # See everything ✅ Real-time execution visualization ✅ Complete execution history ✅ Debug like regular Python code

🚀 Quick Start

📦 Installation

pip install railtracks railtracks[cli]

⚡ Your First Agent in 5 Min

import railtracks as rt

# 1. Create tools (just functions with decorators!)
@rt.function_node
def count_characters(text: str, character: str) -> int:
    """Count occurrences of a character in text."""
    return text.count(character)

@rt.function_node
def word_count(text: str) -> int:
    """Count words in text."""
    return len(text.split())

# 2. Build an agent with tools
text_analyzer = rt.agent_node(
    "Text Analyzer",
    tool_nodes=(count_characters, word_count),
    llm=rt.llm.OpenAILLM("gpt-4o"),
    system_message="You analyze text using the available tools."
)

# 3. Use it to solve the classic "How many r's in strawberry?" problem
text_flow = rt.Flow(
  name="Text Analysis Flow"
  entry_point=text_analyzer
)

text_flow.invoke("How many 'r's are in 'strawberry'?")

📊 Visualize Agent locally with a simple command

railtracks init  # Setup visualization (one-time)
railtracks viz   # See your agent in action

🔍 See every step of your agent's execution in real-time
