Competitive Position

vs n8n

Both offer free tiers and are open-source platforms for low-code automation. Flowise is specifically designed for the optimization of workflows using AI agents and LLMs and can be used for other automation as well, while n8n is a general purpose automation platform that does not include any LLM specific features like memory, data loaders, and model orchestration.

Use Flowise for your AI native application and LLM workflow needs and use n8n for your business process automation needs.

vs Zapier

Zapier leads the market for integration automation with over 5,000 pre-built integrations and an existing user base. While Zapier provides many tools to support the integration of systems, it also does not have the AI first capabilities nor the open source nature of Flowise.

Use Zapier when you need to connect one system to another, and use Flowise when you want to integrate AI into a conversational or autonomous agent.

vs LangChain/LlamaIndex (Libraries)

Flowise uses a visual interface that allows anyone to use the capabilities of LangChain and LlamaIndex without requiring them to write code. This makes it easier for people who do not have programming experience to create their own applications with the capabilities of these two powerful libraries.

Use Flowise if you are a non-technical developer building your own AI application, and use the direct API access for developers that require full control.

Pros & Cons

Pros

  • Start developing your AI agent without the upfront cost or risk of vendor lock-in by starting with an open-source and free-to-use tool.
  • Build and orchestrate complex LLM workflows without writing any code using Flowise's visual drag-and-drop interface.
  • Over 100 integrations are included out-of-the-box including LangChain, LlamaIndex, HuggingFace, Ollama, and many others.
  • Flowise can be self-hosted which means that you can run the tool on your premises or even in an air-gapped environment to maintain complete control over your data.
  • Flowise provides the ability to work with 100+ LLMs as well as local models (HuggingFace, Ollama, LocalAI).
  • Flowise can be deployed in a variety of ways including cloud, on premise, via Docker, and even embedded directly within an application.
  • The Enterprise Tier of Flowise is affordable and includes Single-Sign-On (SSO), SAML, Audit Logs, and a Service Level Agreement (SLA) of 99.99%.
  • The community behind Flowise continues to actively develop the product with new LLM integrations and feature additions being added regularly.

Cons

  • There is limited documentation available for Flowise compared to established platforms and therefore there may be a steep learning curve for users looking to create complex workflows.
  • Much smaller community compared to Zapier or Make — much fewer pre-constructed templates and examples
  • The free-tier has too many restrictions — only 100 predictions/month could possibly limit your ability to test
  • The prediction pricing model is unclear — we are unsure at what point our usage of external API calls will affect our limits
  • Pricing structure for Enterprise is opaque — a quote is needed to determine if you can use truly enterprise-level features
  • As a young platform there are few case studies available — this means that this platform has not been tested as much as the incumbent platforms in a production environment
  • Support depends on which level you have paid for — free users only have community-based support

Best For

Best For

  • AI developers and startupsThe free-tier is based on an open-source platform — allows for rapid development of AI agents and LLM applications before you have to pay anything
  • Individuals and small teams building chatbotsThe $35/month Starter plan, which provides 10,000 predictions per month — is a great price point for deploying small-scale chatbots
  • Companies requiring data privacy and on-premises deploymentSelf-hosting and air-gapped deployment options give you full control over all of your sensitive data
  • Enterprises needing LLM orchestration and AI agent platformsThe Enterprise Tier includes Single-Sign-On (SSO), Audit Logs, Role-Based Access Control (RBAC), Versioning, and a 99.99% Service Level Agreement (SLA) for environments that require regulation compliance
  • Organizations using multiple LLMsSupports native integration with 100+ LLMs and Local Models (Ollama, HuggingFace) without any vendor lock-in

Not Suitable For

  • Non-technical business users unfamiliar with AIMay require knowledge of LLMs, RAG, and Agents. If you want a more straightforward automation solution then Zapier or Make would likely be a better choice.
  • Users needing extensive pre-built integrationsWhile it has 100+ integrations, Zapier currently offers 5,000+ pre-constructed connectors out-of-the-box. Choose Zapier for the most comprehensive integration library.
  • Organizations with very low budgetsThe free-tier is very limiting (100 predictions/month). Either choose one of the fully free solutions or one of the pure open source libraries such as LangChain.
  • High-scale production environments requiring extensive vendor supportIt is a younger platform with less people on the support team than the long-established RPA/automation vendors. Use UiPath or Blue Prism for critical scale.

Faq

Flowise is an open-source low-code platform to build AI Agents and LLM Workflows utilizing Drag-N-Drop Visual Builders. There are multiple builders including Agentflow, Chatflow, and Assistant builders to create a wide range of solutions from simple chatbots to complex Multi-Agent Systems. There are two main deployment methods to choose from: Self Hosting and Cloud.

LangChain is a developer framework that requires writing code, while Flowise is a visual drag-and-drop developer interface that is based on LangChain and LlamaIndex. Flowise allows users who do not write code to create production ready AI agents. Both Flowise and LangChain use the same set of LLMs as well as the same toolset.

Yes, Flowise is fully open source and free for self hosting. It uses a cloud model for which there is a free starter tier that can be upgraded to a paid pro/enterprise tier. There is no vendor lock-in due to its ability to integrate with 100+ LLMs and vector DBs.

Yes, Flowise can be installed locally by running the following one line command in your terminal: npx flowise start. Flowise supports docker deployment and can scale horizontally with message queues and worker processes. Therefore it can be run entirely on premises.

Flowise currently supports integration with 100+ different LLMs including OpenAI's GPT-4o, Google Gemini, Anthropic Claude, AWS Bedrock, and many other LLMs through an interface called Ollama / LM Studio, as well as Open Source LLMs. In addition to LLMs, Flowise supports all types of embeddings and vector databases.

Flowise can be deployed either as a managed service via Flowise Cloud or as a self hosted solution. Once deployed, production grade flows will have REST API endpoints available to make predictions against them. Additionally, you can embed Flowise chat widgets directly into websites via SDKs. Also, since Flowise uses a horizontal scaling model, it is possible to add additional worker nodes to increase processing capacity.

When deploying Flowise on premises, you retain complete control over your data. On the other hand, when you deploy Flowise on the cloud, you gain access to the same level of enterprise grade security as provided by the cloud provider, such as API key based security. In addition, both Flowise cloud and on premises solutions provide the ability to include a human in the loop to review high risk decisions made by AI models. Finally, both solutions allow you to integrate with your own enterprise wide vector store.

While Flowise can easily manage complex agent systems, it is still likely that some very complex agent systems will need to be implemented with custom code. Additionally, even though the cloud version of Flowise has a free tier, it does come with limitations on usage. Another limitation is that Flowise does not have a native app builder for building mobile apps. However, Flowise was designed specifically to handle structured LLM orchestration rather than arbitrary software automation.

Expert Verdict

As a fully open source visual builder for both AI Agents & LLM Orchestration, Flowise provides an alternative to developers and non-developer alike in terms of developing an AI Agent. With its Node Based Architecture that can support anything from basic RAG Chatbots, to Complex Multi-Agent Workflows that include Human-in-the-Loop, it also provides an unprecedented amount of Value via Free Self Hosting, Multiple Integrations, & Production Deployment Options.
