Three tools, three jobs
How is Dify differentfrom the other tools?
Three tools, three jobs — together they make a complete AI stack
OpenClaw
AI agent assistant
Your AI virtual employee. It drives a browser, pulls data and holds a conversation to get the work done for you.
- Browser automation
- Data extraction & scraping
- Extensible skill system
- No knowledge base
n8n
Workflow automation
Wires apps together. Email lands in Gmail → Slack gets pinged → the row is logged to Google Sheets. All automatic.
- 400+ app integrations
- Webhook triggers
- Scheduled automation
- Not AI-specific
Best combo: n8n catches the event → Dify's AI handles it → n8n delivers the result. Three tools, three jobs.
Core features
What can Dify do for you?
Build a serious AI app without writing code
RAG knowledge base — teach the AI your data
Upload company documents, product manuals and FAQs, and Dify builds the vector index for you. Answers cite your own data instead of making things up.
- Word
- Web pages
- CSV
- Markdown
- Notion sync
AI workflow editor
Design an AI app the way you'd draw a flowchart. Add conditions, loops and HTTP calls to build real logic.
APIs generated for you
Every AI app gets a REST API automatically. Drop that AI into your own site, app or LINE bot.
Use cases
Who is Dify for?
Whatever your industry, Dify can build an AI that's yours
Small businesses
Build an internal knowledge base AI so new hires can just ask it. A support AI handles the common questions and saves real headcount.
E-commerce & brands
Feed the AI your product data. A customer asks "do you have this in red, size M?" and gets an instant answer — far smarter than a static FAQ.
Education & training
Upload your course material and students can ask the AI teaching assistant anytime. It reads the context of a question better than a search box.
Developers
Prototype AI apps in Dify, then integrate them into your own product through the API. Skip building RAG from scratch.

FAQ
Common questions
What does self-hosting Dify cost per year compared with RoamerHost?
Dify officially recommends at least 2 vCPU and 4 GB of RAM, so self-hosting usually means a VPS at roughly US$8–15 a month (about NT$250–480), or NT$3,000–5,800 a year in server fees. On top of that you deploy it with Docker Compose, set up the domain and SSL, keep up with frequent releases and look after database backups. Managed Dify on RoamerHost starts at NT$1,599/mo, about NT$19,188 a year, and already includes one-click deployment, built-in SSL and automatic backups. If you have DevOps experience and want to customize the stack, self-hosting is more flexible. If you would rather focus on designing AI apps, managed is far less work.
Can I export my AI apps and data? Am I locked in if I want to leave?
No lock-in. Dify apps export as DSL files, and your knowledge base documents and API settings stay under your control, so you can move to a self-hosted or third-party Dify at any time. RoamerHost runs the standard open-source Dify — nothing proprietary.
Can I embed a Dify app in my website or in LINE?
Yes. Every Dify app ships with an API and an embeddable web widget, so you can put the chatbot on your own site or connect it through the API to LINE, Messenger and other channels and let customers talk to your AI directly.
What is Dify, and how is it different from ChatGPT?
Dify is not a chat tool; it is a platform for building AI applications. You can use it to build your own ChatGPT, except backed by your own knowledge base so the AI answers questions about your business. ChatGPT is general-purpose AI; Dify lets you build AI that is specific to you.
Do I need to bring my own LLM API key?
Yes. Dify is the platform, so you supply the API key for the model you want (OpenAI, Claude, Gemini and so on). The upside is that you pick the model and control the cost yourself.
How do Dify, OpenClaw and n8n differ?
Dify is the AI brain: it turns your documents into an AI knowledge base. OpenClaw is the AI employee: it drives a browser and does work for you. n8n is the automation engine: it connects 400+ apps and runs the workflows. They complement each other and work best together.
How does this compare with the official Dify Cloud plans?
The free Dify Cloud tier is tightly limited (number of knowledge bases, API calls and so on), and paid plans start at US$59/mo. RoamerHost gives you an isolated project with no usage caps, and your data stays entirely inside your own container.
Can I use it if I cannot write code?
Absolutely. No-code is the whole idea behind Dify. Upload documents, drag out the flow, click publish — not a single line of code required.
