ConnectOnion - Best Agent Framework for Python

The Truth About Those $199 Courses

People are selling expensive courses for what's essentially a simple concept:

"Master LangChain in 30 Days!"$199

"AutoGen Expert Certification"$299

"Complete CrewAI Bootcamp"$499

The "Secret" Formula

AI Agent = Prompt + Function

That's it. That's the entire course. Let me show you why.

Why I Built ConnectOnion

I was building a project with LangChain and got frustrated:

Simple agent required 100+ lines of code
Documentation was incomprehensible
Every update broke my code

See the Difference

LangChain: 67 lines of complexity

main.py

from langchain.agents import Tool, AgentExecutor, LLMSingleActionAgent
from langchain.prompts import StringPromptTemplate
from langchain.chains import LLMChain
from langchain.schema import AgentAction, AgentFinish
from langchain.chat_models import ChatOpenAI
# ... 20 more imports ...

class CustomPromptTemplate(StringPromptTemplate):
    # ... 30 lines of boilerplate ...

class CustomOutputParser:
    # ... 25 lines of parsing logic ...

# Finally create the agent (line 67)
agent_executor = AgentExecutor.from_agent_and_tools(...)
result = agent_executor.run("What's the weather in San Francisco?")

ConnectOnion: 5 lines of simplicity

main.py

from connectonion import Agent

def get_weather(city: str) -> str:
    return f"The weather in {city} is sunny, 72°F"

agent = Agent("weather_bot", tools=[get_weather])
result = agent.input("What's the weather in San Francisco?")
