# Choose Your Integration

> Pick the right cascadeflow integration for your framework — LangChain, OpenAI Agents, CrewAI, Google ADK, n8n, Vercel AI, or Hermes Agent.

# Choose Your Integration

cascadeflow integrates with every major agent framework. Pick the one that matches your stack.

## By Language

### Python

All Python integrations share the same Harness API — `init()`, `run()`, `@agent()`. The framework integration handles the bridge:

```python theme={null}
# LangChain — callback handler
from cascadeflow.integrations.langchain import CascadeFlowHandler
handler = CascadeFlowHandler()
chain.invoke(query, config={"callbacks": [handler]})

# OpenAI Agents — model provider
from cascadeflow.integrations.openai_agents import CascadeFlowModelProvider
provider = CascadeFlowModelProvider()

# CrewAI — hooks
from cascadeflow.integrations.crewai import CascadeFlowHooks
hooks = CascadeFlowHooks()

# Google ADK — plugin
from cascadeflow.integrations.google_adk import CascadeFlowPlugin
plugin = CascadeFlowPlugin()

# Hermes Agent — delegation router
from cascadeflow.integrations.hermes import HermesDelegationRouter
router = HermesDelegationRouter.from_dict({"enabled": True, "mode": "observe"})
```

### TypeScript

```typescript theme={null}
// Core (standalone)
import { CascadeAgent } from '@cascadeflow/core';

// Vercel AI SDK (middleware)
import { createChatHandler } from '@cascadeflow/vercel-ai';

// LangChain (withCascade)
import { withCascade } from '@cascadeflow/langchain';
```
