AI Frameworks & SDKs
These frameworks are the building blocks for AI-powered applications. They handle prompt management, chain orchestration, retrieval-augmented generation, and agent workflows — with DeepSeek as the reasoning engine.
LangChain — The most popular AI orchestration framework. Build chains, agents, and RAG pipelines with DeepSeek using the ChatOpenAI connector. Supports Python and JavaScript. Ideal for developers building complex AI workflows that combine DeepSeek with tools, memory, and data retrieval.
LlamaIndex — The leading framework for data-connected AI. Build retrieval-augmented generation systems that let DeepSeek answer questions from your documents, databases, and APIs. Specialized in indexing, chunking, and vector search for knowledge-intensive applications.
Semantic Kernel — Microsoft’s enterprise AI orchestration SDK. Build production-grade agents with plugins, planners, and memory in C#, Python, or Java. DeepSeek works through the OpenAI connector with three lines of configuration. The go-to choice for .NET teams and enterprise environments.
Vercel AI SDK — The TypeScript toolkit for building AI-powered web applications. Stream DeepSeek responses to React, Next.js, Svelte, and Vue frontends with built-in UI components. The fastest path from DeepSeek API to a production chat interface.
OpenAI SDK — Use the official OpenAI Python and Node.js libraries with DeepSeek by changing one line: the base URL. The simplest integration for developers already familiar with OpenAI’s API format. No new library to learn.
LiteLLM — A unified interface for 100+ LLM providers. Use LiteLLM as a proxy to route requests to DeepSeek, track costs, set rate limits, and switch between providers without changing your application code. Essential for teams managing multiple AI models.
Web Frameworks

Automation & No-Code Platforms
Build AI-powered workflows without writing code — or with minimal code. These platforms connect DeepSeek to thousands of other services through visual builders and drag-and-drop interfaces.
n8n — The open-source workflow automation platform. Connect DeepSeek to 1,000+ integrations using the native DeepSeek Chat Model node or the AI Agent node. Build automated content pipelines, data processing workflows, and AI-powered notifications.
Zapier — Automate DeepSeek across 7,000+ apps with zero code. The native DeepSeek app provides actions for Chat, Reasoner, Fill-in-the-Middle completion, and more. Build Zaps that trigger DeepSeek responses from emails, forms, Slack messages, and any other event.
Dify — An open-source LLM application platform for building chatbots, agents, and AI workflows. Provides a visual builder, RAG engine, and plugin ecosystem. Deploy DeepSeek-powered applications with a drag-and-drop interface and no backend code.
Flowise — Build LLM applications with a visual drag-and-drop interface. Connect DeepSeek to vector databases, document loaders, and memory modules using a node-based canvas. The native ChatDeepSeek node makes setup effortless.
AI Code Editors
Write code faster with DeepSeek as your AI programming assistant. These guides cover dedicated AI editors, VS Code extensions, and terminal-based tools.
Cursor — The AI-first code editor with DeepSeek built in as a non-premium model. Tab completion, Chat, Composer, inline edit, and Agent Mode — all powered by DeepSeek at no extra credit cost. The most polished AI coding experience available.

Getting Started
Every integration on this page connects to DeepSeek through the same API. Before diving into any guide, make sure you have the basics covered.
Create a DeepSeek account and get your API key from the DeepSeek platform. Our login guide walks through the process. Top up your account with a small amount to start — most development and testing costs under $1/day.
Choose your model. deepseek-chat is the general-purpose model (DeepSeek V3.2) with fast responses and broad capabilities. deepseek-reasoner adds chain-of-thought reasoning for complex analytical tasks. See our models hub for a detailed comparison and our DeepSeek V3 page for technical specifications.
Understand the pricing. DeepSeek charges $0.28/M input tokens and $0.42/M output tokens — among the most affordable rates in the industry. Cached inputs cost $0.028/M (90% discount). See our pricing page for the full breakdown and cost calculator.
Check the API format. DeepSeek’s API is fully compatible with the OpenAI chat completion format. Any tool that works with OpenAI can work with DeepSeek by changing the base URL to https://api.deepseek.com. See our API documentation for endpoints, parameters, and examples.
Which Integration Should You Start With?
If you are a developer building an AI application, start with LangChain (Python) or Semantic Kernel (C#/Java) for the framework, and Next.js or FastAPI for the web layer.
If you want AI coding assistance, start with Continue (free Copilot replacement) or Cursor (dedicated AI editor). Add Cline for autonomous agent tasks.
If you want AI without writing code, start with n8n (open-source) or Zapier (easiest setup) for automation, or Dify / Flowise for visual AI app building.
If you want complete privacy with local AI, start with Ollama for the model runtime, then add Open WebUI for the chat interface or Obsidian for knowledge management.
If you want instant AI in your daily Mac workflow, install Raycast — one hotkey for DeepSeek from any application.
