Quick answer
Yes. You can build a simple AI agent without writing code: give it one job, one source of information and written instructions, test it on real examples, add a human approval step, then switch it on. Zapier Agents, n8n and Lindy each state a free way to try and Make's page says "Get started free"; check each unit first.
Key takeaways
- A first agent needs six things in order: one job, one data source, written instructions, a test set, a human approval step, then go live.
- The four builders compared here (Zapier Agents, Make, n8n, Lindy) each state something about human approval, in different forms: a sentence you write, options, or a default.
- Free options are not comparable: Zapier's Agents plan counts activities, Make's help center counts credits, n8n's trial is measured in days (14), and Lindy's free credits last 7 days.
- Zapier says it is moving Agents to AI by Zapier, so check which one your account shows before you follow any setup guide.
- This site's rule: if the steps never change, build a plain automation; use an agent only when the input needs judgment.
Can you build an AI agent without coding?
Yes. You can build a simple AI agent (one task, a few connected apps, a human check) without writing code; Zapier Agents, n8n and Lindy each state a free way to try, and Make's page says "Get started free". Asked whether you need coding experience, Make's page answers "No" and says "You build AI agents using Make's visual builder." Zapier's setup guide has you type instructions and connect your apps.
"Simple" is the limit of this page: one job, a short checklist, and you read every message before it goes out. What an agent is, is a separate question. For which jobs are ready to hand over, see the AI agents for small businesses page.
How do four no-code agent builders compare?
Each of the four publishes an agent builder page, a pricing page and a statement about approvals; the table gives each in the vendor's words. This is not a ranking and it does not cover every builder. Facts as of October 7, 2026.
| Builder | What the vendor says it is | Connects to | Human approval, per the vendor |
|---|---|---|---|
| Zapier Agents | Agents that "perform tasks across 9,000+ apps" | 9,000+ apps | Help article: add "a sentence like" "ask for my confirmation through [messaging app] before continuing to the next instructions" |
| Make AI agents | "Build AI agents you can share across teams and workflows" | "3000+ apps" | Product page FAQ: "You can set clear rules, add manual approvals, or stop the agent at specific points" |
| n8n | "AI agents, human approvals, and code" blended "into flexible workflows" | "500+ integrations" | Product page: "Place human-in-the-loop checks at any point in a workflow or in front of any AI agent tool" |
| Lindy | "Your AI teammate that plugs into your tools" | "1,500+ integrations" on its pricing page | Pricing FAQ, stated as default behavior: "Anything with outside impact waits for approval", such as sending an email |
All four are statements about a person approving an agent's action, but the mechanism differs: Zapier's is a sentence you write into the instructions, Make's and n8n's are options, and Lindy's is a default.
Free options are counted in different units, so they are listed separately from prices:
| Builder | Free option, in the vendor's words | What the number counts | Condition stated |
|---|---|---|---|
| Zapier Agents | Agents plan labelled "Free forever": "up to 400 times per month" | Activities ("400 activities per month") | An activity is an action the agent takes in behaviors or in chat, browsing the web, or looking up attached knowledge |
| Make AI agents | "Get started free"; agents "Available on all plans" | Not stated on the pages we read; the help center counts usage in credits | Free-plan size not stated on the pages we read |
| n8n | "14 days free trial. No credit card required." | Days | The pricing page lists trial limits including 1,000 executions; a standard self-hosted version is also on GitHub |
| Lindy | Free credits that "last 7 days" | Credits | The free week is one-time per teammate; monthly credits do not roll over |
A plan label, a trial length and a credit allowance are different things. Zapier's main free plan is separate from its Agents plan and lists "100 tasks per month" for Zaps, Tables and Forms.
Each vendor also states limits or changes:
- Zapier: "Zapier is moving agents to AI by Zapier", with no date set to turn Agents off; agents cannot be embedded on a website.
- Make: "Users on paid plans can also use custom AI provider connections".
- n8n: its plan table marks "Agents (preview)".
- Lindy: the free week is one-time per teammate, and monthly credits "don't roll over".
Zapier shows more caveats mainly because we read its help articles; for the others, product and pricing pages.
Which builder fits your situation?
Match your need to a fact the vendor documents; the rule is this site's, the facts are theirs.
| If your need is… | Look at… | Because the vendor documents |
|---|---|---|
| A chat you can put on your own website | n8n; for Zapier, Zapier Chatbots | n8n's plan table lists "Hosted and embedded chat". Zapier says "Agents cannot be embedded on a website or shared as a live, customer-facing experience." and points to Zapier Chatbots. The Make and Lindy pages we read do not say |
| Agents next to automations you already build in Make | Make | Agents built in "Make's visual builder" and "Available on all plans" |
| A tool you can run on your own server | n8n | "A standard, self-hosted version of n8n is available on GitHub." |
| An assistant that works inside your team's chat | Lindy | A "Slack-native teammate in threads + mentions", with approvals before outside-impact actions |
If you already have an account with one of the four, try that one first; that is this site's rule of thumb, not a vendor's. Our no-code automation platforms guide and the Zapier vs Make comparison cover the plain-automation choice. For one pair, see n8n vs Power Automate.
How do you build your first agent in six steps?
Do these six in order; the example is a lead-reply agent built in Zapier Agents. Zapier says it is moving Agents to AI by Zapier; these steps are documented for Agents, so check which one your account shows; this page did not read the AI by Zapier setup steps. The six steps are this site's method. Zapier Agents is the illustration only because its help pages document these steps; it is not a recommendation. For another builder, follow that vendor's own guide.
- One job. Write one sentence: "When a new lead emails us, draft a reply that answers their question and offers two times to talk." Draft, do not send. Zapier's best-practice page says to "Keep agents focused on 3-5 related actions rather than creating one agent that does everything."
- One data source. Give the agent the one document it needs, such as your price list and service-area page. Zapier's guide says to "Add knowledge sources to provide your agent with data it can reference."
- Instructions. Zapier's guide says to "Be explicit about triggers: clearly define when and how the agent should activate." Name the inbox and the tone.
- A test set. Collect real past enquiries, including odd ones: a vague one, an angry one. Zapier's guide says "Use actual examples from your workflows rather than sample data."
- Human approval. Zapier's help page says that to make an agent stop for your confirmation you "can add a sentence like" "ask for my confirmation through [messaging app] before continuing to the next instructions." The agent then waits for your confirmation, and needs access to a messaging app to ask.
- Go live. In Zapier Agents you "click Publish to activate the agent." Then read every draft for the first week.
When is a plain automation better than an agent?
This site's rule: build a plain automation when you can write the steps as a fixed list; use an agent when the input needs judgment. Make draws a similar line: "If it just needs doing, use automation. If it needs thinking, use Make AI agents."
A form that always copies a name into a spreadsheet is an automation. A lead email that might be a quote request, a complaint or spam needs reading first, and that is where an agent earns its place.
What does it cost to start?
Start on a free option, and compare units before prices: the four count different things. Zapier's Agents plan counts activities; AI by Zapier "uses the same task-based pricing as the rest of Zapier," not a separate agents subscription. Make's help center counts usage in credits. n8n says its "Pricing based on monthly workflow executions" and offers a 14-day trial. Lindy sells by seat: "Anyone who uses Lindy takes a seat."
This page prints no plan prices because the pricing pages we read on October 7, 2026 did not give us one currency we could confirm (n8n's showed euros and Make's did not load), so see each vendor's pricing page.
When should you stop and hire help?
Stop when the agent would act on money, legal matters or customers without a human check, or when you cannot say what a wrong answer costs. This is this site's advice. Three cases:
- Customer-facing chat. Zapier's help page says "Agents cannot be embedded on a website or shared as a live, customer-facing experience," and for that points to "Zapier Chatbots." n8n's plan table lists "Hosted and embedded chat". The Make and Lindy pages we read do not say. Confirm with the vendor first.
- Writes to your books or CRM. Keep the approval step on until the test set passes cleanly.
- Repeated odd results. If the same kind of enquiry keeps failing after you rewrite the instructions, bring in a professional.

How was this page made?
The vendor statements above were read on the vendors' own pages on October 7, 2026, from outside the United States, and each quote is copied from a page named in the sources. Where a page did not state something, we say so. This page was drafted with Claude, an AI model made by Anthropic, and checked against each vendor's published material.
Your next step: pick the row in the decision table that matches your need, open that vendor's free option, and build only step 1 and step 2 today. If the agent drafts a sensible reply to your first three past enquiries, continue to step 3.
FAQ
Can I build an AI agent without coding?
Yes for a simple one: Make's page answers 'No' to whether you need coding experience, and Zapier's setup guide has you type instructions and connect apps; the n8n and Lindy pages we read do not state a coding requirement either way.
What is the difference between an AI agent and an automation?
Make states the dividing line this way: 'If it just needs doing, use automation. If it needs thinking, use Make AI agents.' This site adds one test: if you can write the steps as a fixed list, build the automation.
Can the agent act without my approval?
Only if you allow it: Zapier has you add a confirmation sentence, Make and n8n offer approval options, and Lindy's FAQ says outside-impact actions wait for approval. Set it before you go live.
Can I put the agent on my website as a customer chat?
It depends on the builder. Zapier's help page says agents cannot be embedded on a website, and points to Zapier Chatbots. n8n's plan table lists 'Hosted and embedded chat' for agents. The Make and Lindy pages we read do not say. Ask before you promise it.
