One of the first decisions you face when building with Flowise is which builder to use. The platform gives you three major options: Assistant, Chatflow, and Agentflow. Each of these builders reflects a different philosophy for designing AI-powered applications. Think of them as three different workbenches in the same workshop. You would not use a woodworking bench to weld steel, and you should not expect the same builder to be the best fit for every AI project. Choosing wisely at the start saves time, reduces complexity, and helps you build a solution that scales smoothly.

Understanding the Flowise Builders
Before you can decide which builder is right for your use case, it helps to understand what each one is designed to do. While they share common building blocks, the goals and workflows of each builder are distinct.
Assistant
The Assistant builder is the simplest option and is perfect for quickly creating AI assistants that handle straightforward conversations. It uses a guided setup and a preconfigured structure, making it ideal for beginners or for rapid prototyping. You can think of it as a “plug and play” option. While it lacks the depth of customization found in other builders, it shines when you want to launch something functional without heavy technical investment.
Chatflow
Chatflow is the workhorse builder of Flowise. It provides a visual canvas where you connect nodes to design conversation logic, data integrations, and advanced prompts. Chatflow strikes a balance between flexibility and usability. You do not need to be a developer to use it effectively, but you also have the freedom to create complex conversational structures. It is ideal for chatbots, document Q&A systems, and customer service agents that need to integrate with multiple sources of information.
Agentflow
Agentflow represents the most advanced tier. Here, you can build autonomous agents capable of multi-step reasoning, tool usage, and decision-making. Instead of simply responding to inputs, Agentflow-powered systems can plan, act, and adapt. They are designed for workflows where the AI takes on tasks that stretch beyond single-turn interactions. Agentflow is well-suited for business automation, research assistants, or any system where autonomy and orchestration matter.
Comparing Use Cases
To decide between the three, let’s break down practical scenarios where each shines.
- Assistant: A startup founder needs a simple website chatbot to answer basic FAQs. They choose Assistant to get something live within an hour.
- Chatflow: A university wants a tool for students to query course catalogs and policy documents. Chatflow offers the right mix of custom logic and integrations.
- Agentflow: A logistics company needs an AI system that can not only answer questions but also schedule deliveries, generate reports, and interact with APIs. Agentflow enables this autonomy.
Strengths and Limitations
No builder is inherently “better” than the others. Each one has strengths that align with different needs. Let’s look closer at the trade-offs.
Assistant strengths
- Fastest setup, minimal configuration.
- Great for prototypes and small-scale deployments.
- User-friendly for non-technical staff.
Assistant limitations
- Limited customization options.
- Not designed for complex workflows.
- Scalability may be limited for enterprise use.
Chatflow strengths
- Visual builder that balances power and simplicity.
- Supports multiple integrations and branching logic.
- Good for chatbots, Q&A, and customer service.
Chatflow limitations
- Requires some learning curve for complex designs.
- Still less autonomous compared to Agentflow.
Agentflow strengths
- Autonomous behavior and tool orchestration.
- Capable of multi-step reasoning and planning.
- Powerful for enterprise automation and advanced agents.
Agentflow limitations
- Steeper learning curve.
- More resources required for setup and monitoring.
- Not necessary for simple, single-purpose assistants.
Choosing the Right Builder
So, how do you pick the right builder for your Flowise project? Start by asking yourself a few questions:
- What is the complexity of the task? If it is simple FAQs, Assistant may be enough.
- Do I need integrations with multiple data sources? Chatflow is designed for that.
- Do I need the AI to act autonomously and make decisions? Agentflow is the best fit.
- What is my timeline? If speed matters most, Assistant wins.
- What resources do I have for development and monitoring? Complex projects may require Agentflow’s power but also more oversight.
Tips for Teams
If you are working in a team setting, consider combining builders. For example, you might start with Assistant to test user interest, then move to Chatflow when you need more features, and eventually adopt Agentflow for full autonomy. Flowise makes it possible to evolve your projects in this way without starting over from scratch.
Best Practices
- Prototype quickly: Use Assistant to validate ideas before investing in complex designs.
- Document logic: In Chatflow and Agentflow, label your nodes clearly to avoid confusion.
- Test often: Regular testing ensures your workflows behave as expected.
- Keep humans in the loop: Especially in Agentflow, design checkpoints for oversight.
- Think about scalability: Choose the builder that not only meets today’s needs but can grow with tomorrow’s demands.
Assistant, Chatflow, and Agentflow each have their place in the Flowise ecosystem. The right choice depends on your goals, resources, and timeline. By understanding their strengths and limitations, you can align the builder with your project’s needs and avoid unnecessary complexity. Remember, the best builder is the one that gets you from idea to impact with the least friction. Flowise gives you options, and that flexibility is its greatest strength.
