Why is Dify chosen? Differences from major tools like LangChain and Autogen
"I want to introduce generative AI into my company, but where should I start?"
"I want to develop and test AI apps quickly without writing code!""I tried LangChain, but it was too difficult and I gave up."
If you are facing these challenges, "Dify," which allows you to develop generative AI apps with no-code/low-code, will be the solution.
In this article, we will uncover why Dify is chosen among many development tools by comparing it with major tools.
📌 To those reading this Note
At WEEL, we hold various seminars for those who want to incorporate generative AI into their business and operations.
For those who are wondering, "What kind of applications are possible?" or "How should I start in my company?", we introduce know-how from a field perspective and the latest case studies.

What is Dify? Why Dify is chosen among many no-code tools
In short, Dify is an "open-source platform that allows anyone to quickly develop and operate AI apps using Large Language Models (LLMs)."
Its name is a combination of "Define" and "Modify," reflecting the desire to "create AI apps quickly and keep improving them."
The reason why Dify is chosen by many users is that it combines ease of use, flexibility, and practical features.
For example, even if you have little programming experience, you can use Dify to create AI chatbots as if you were assembling parts on a screen. Therefore, even non-engineers can easily start developing AI apps.
Also, because it is provided as open source, it is easy to customize freely and introduce into your own company's environment, allowing it to flexibly meet unique corporate needs.
Since it is equipped with the features necessary for full-scale operation (BaaS/LLMOps*), a major strength is that you can complete everything from idea prototyping (PoC) to production use in business with just Dify.
*BaaS: Abbreviation for Backend as a Service, referring to the backend functions necessary for operating AI applications
LLMOps: A set of practices and processes including deployment, maintenance, and optimization
For more details on the overview of Dify, please refer to the following note.
Functional comparison with major tools
We have summarized the differences between Dify and tools often compared with it in a table. First, let's roughly grasp the positioning of each tool.
Dify vs LangChain: Code flexibility or development speed
"If you want to first quickly verify the value of AI" or "involve non-engineers in development," Dify is optimal.
On the other hand, if you have requirements to "implement complex processing" or "have complete control over the details," LangChain will be a strong candidate.
Dify vs Autogen: Flexibility in agent design
When it comes to creating autonomous AI agents, Dify and Autogen have different areas of expertise.
If you want to develop advanced agents where multiple AIs autonomously discuss and collaborate, we recommend Autogen.
On the other hand, for those who want to quickly build practical workflows such as "searching for information from websites and summarizing it," Dify's Agent features will be reliable.
Dify vs Flowise/Gradio: Differences in GUI workflows
Even with similar GUI-based tools, you need to choose the right one for your purpose. Dify is designed with everything from prototyping to production operation in mind.
If your main goal is idea validation or demo creation, then Flowise or Gradio may be sufficient.
However, if you "want to continuously operate and improve the AI apps you create in a business environment," then Dify, which integrates BaaS/LLMOps features, is the better choice.
Dify vs Zapier/n8n: Distinctions from no-code automation
While they are both no-code development platforms, Dify, which focuses on "AI application development," and Zapier or n8n, which aim for "automation of routine tasks," have different areas of expertise.
Dify is a platform specialized in "AI application development" using LLMs, allowing you to handle everything from prototyping to production operation consistently.
It excels at building AI apps that handle non-routine tasks using features like RAG without writing code.
On the other hand, Zapier and n8n are tools (iPaaS) for automating routine tasks by connecting existing apps. They can handle complex workflows and incorporate LLMs as part of those processes.
Therefore, if you are developing an AI application from scratch and looking ahead to operation, Dify is the way to go, whereas if you want to automate existing business workflows and add AI features to parts of them, n8n or Zapier are more suitable.
You can also combine them for advanced usage, such as linking content generated in Dify to various SaaS platforms via n8n or Zapier.
Dify's strengths and weaknesses by use case
Let's look at what Dify is good at and what it struggles with through specific use cases.
[Dify's strengths and effective use cases]
・Internal FAQ chatbots・RAG (Retrieval-Augmented Generation) systems
・Automatic summarization and polishing of sales reports and meeting minutes・AI assistants embedded in websites
[Dify's weaknesses and points of caution]
・Implementation of overly complex custom logic・Slow performance for large-scale batch processing
・Basic permission management (self-hosted version)
To determine if Dify is right for your company, you need to consider the optimal implementation method in two steps: "the challenges you want to solve" and "your company's situation."
Step 1: Does the challenge align with Dify's strengths?
If the challenge falls under [Dify's strengths and effective use cases], such as "internal FAQ automation" or "knowledge retrieval via RAG," Dify is effective.Conversely, if complex logic or large-scale processing—which are its weaknesses—is essential, you should consider other tools.
Step 2: What is the optimal deployment method for Dify?
Cloud Version: Best for when you want to try it out quickly and without hassle. It is suitable for startups and business departments that want to run PoCs rapidly.
Self-hosted Version
: Choose this if you need to operate in an internal environment to handle confidential information. It is intended for companies that prioritize security and cost.
About Pricing and Licensing
Dify offers a "Cloud Version" that is easy to try, and a "Self-hosted Version" that can be operated safely on your own servers.
The Cloud Version has free plans and paid plans for businesses, while the Self-hosted Version is open source (Apache 2.0), so there are no license fees.
For a more detailed plan comparison, this note explains it in an easy-to-understand way.
Dify is ideal for companies that want to go from PoC to production seamlessly
In this article, we compared the differences between Dify and major generative AI-related tools from multiple perspectives.
Once again, Dify is best suited for companies and teams with the following needs.
・You want to prioritize the speed of AI development with no-code/low-code.
・You want to involve not just engineers, but also business-side staff to turn ideas into reality.・You want to grow AI apps to a level usable in the field and improve them continuously, rather than ending at a PoC (Proof of Concept).
・You are looking for a flexible and secure deployment method through open source or self-hosting.
While the flexibility of LangChain and the advanced design of Autogen are attractive, what is important for many companies is "how to gain a successful experience in AI utilization quickly and at low cost."
Dify can be said to be one of the most balanced answers to that challenge.
Furthermore, Dify's active community and future potential are also major attractions. It has over 70,000 stars on GitHub and is attracting high attention from developers around the world.
The frequent updates and development stance that reflects the voices of the community indicate that Dify will continue to evolve in the future. This confirms that it is a development foundation that can be used with peace of mind in the long term.
