The best no-code AI agent builder is the one that matches what your agent does all day. If it mostly moves data between apps, pick Zapier Agents, or n8n if you want to self-host. If you want a team of agents for sales, support or operations, look at Lindy or Relevance AI. For a chatbot that answers from your documents, try Dify or Botpress. To build a small AI app or pipeline, try VectorShift or Rentprompts. Every one of these has a free plan or a free open source edition, so you can test before you pay.
A no-code AI agent builder lets you create an agent (software that reads, decides and acts with a language model) in a visual editor or with plain language instructions, without writing code. This guide groups the builders listed on AI Agents Live by the job they do best, gives the rating each has from reviewers, and ends with how to choose and a plan for your first week.
For agents that connect your apps
Zapier Agents work across more than 7,000 apps and take instructions in plain language, such as "when a lead fills in the form, research the company and update the CRM". Zapier has a 4.5 rating on AI Agents Live, and it is the quickest start if your team already uses Zapier.
n8n is a visual workflow builder with AI agent steps, and you can self-host it. It has a 5.0 rating. It sits on the line between no-code and low-code: you can build most flows by dragging nodes, and a developer can add code where needed. My step-by-step n8n guide walks through a first workflow.
Activepieces AI Agents set up in four steps, connect to hundreds of tools and take instructions in natural language. Activepieces is open source, so it suits teams that like n8n's self-hosting but want a simpler editor.
For a team of business agents
Lindy builds agents from plain language instructions and connects to over 3,000 tools. People use it for support, sales outreach and admin work. It has a 4.3 rating.
Relevance AI lets you build single agents and multi-agent teams in one visual platform and monitor them in one place. It has a 4.3 rating and suits companies that want several agents working on one process, such as research, outreach and follow-up.
PromptOwl supports several AI models, so you can switch providers, and adds prompt versioning and team collaboration. It has a 4.3 rating. Kuverto combines an agent builder, a workflow designer and knowledge bases, with a 4.5 rating.
For chatbots that answer from your documents
Dify is an open source platform with a visual workflow editor, a retrieval pipeline for your documents, agent features and observability. It is a strong choice for a support or internal knowledge bot, and it has a 4.0 rating. Read its licence before you offer it to customers as a hosted service.
Botpress is built for conversational agents, with a studio for conversation flows and a messaging API for your channels. Recomi turns uploaded PDFs, spreadsheets and documents into a support agent you embed on your website.
For AI apps and pipelines
Rentprompts is a drag and drop studio for AI apps and agents, and it has the highest rating in the no-code category on AI Agents Live, a 4.8 rating. VectorShift builds agents and pipelines that connect your data sources, tools and models, with a 4.4 rating. LLMStack is an open source option for chaining models with your data.
If you built on Flowise, its open source project was archived in August 2026. I compare where to move in the Flowise alternatives guide.

How to choose
- Write down the one task your first agent will do, with its input, the tools it needs and what "done" looks like.
- Check that the builder connects to those tools today, without a custom integration.
- Look at where your data goes. If it must stay inside your company, choose a builder you can self-host, such as n8n, Dify or Activepieces.
- Read how the builder charges: per task, per credit, per seat or per model call. A busy agent on a per-task plan costs more than you expect.
- Check that you can export your work. Prompts, flows and knowledge bases you can export are easy to move later.
- Look for testing and monitoring. You will want to see every step an agent took when something goes wrong, and I cover that in my guide on how to test and monitor AI agents.
Your first week
On day one, build the agent for your one task in two builders from the list above. On days two to four, run both on the same ten real examples and note which answers are right. On day five, pick the winner, switch it on for a small share of real work, and keep a person checking its output for the next two weeks.
Questions people ask
What is the best free no-code AI agent builder?
For self-hosting, n8n and Dify are free and open source (n8n under its fair-code licence). For a hosted free plan, Zapier, Lindy, Relevance AI and VectorShift all let you build and test an agent before you pay.
Can I build an AI agent without coding?
Yes. Every builder in this guide works in a visual editor or with plain language instructions. You will still need to think like a builder: define the task, give the agent the right tools and test it on real examples.
What is the difference between no-code and low-code agent builders?
A no-code builder lets you finish the whole agent in its editor. A low-code builder, such as n8n, does most of the work visually and lets a developer add code for the unusual parts.
