What we compare, and how

An AI automation tool does two jobs. It moves data between your apps on a trigger or a schedule, like workflow automation software always has. And it lets a model handle the steps that used to need a person: reading an email, sorting a ticket, drafting a reply.

This ranking keeps the tools that do both: general workflow builders with a real app catalog and AI steps or agents inside. Assistants you only chat with (Lindy, Gumloop) and builders made for customer-facing chatbots (Botpress, Voiceflow) are compared in the full ranking instead.

Scores come from the formula published on the methodology page, fed by what each vendor publishes.

Runs, tasks or credits: which unit costs you least?

Take one workflow with 8 actions that runs 1,000 times a month. A tool that bills per run counts 1,000 units. A tool that bills per action counts about 8,000. Neither is wrong, but the second punishes long workflows and the first punishes frequent triggers. Count your actions and your runs before you read a price list.

The 7 tools, one by one

Who each one suits, three strengths, the catch, and the entry price read on Nov 15, 2026.

1Top pick

n8n

Low-code, source-available

Best for technical small teams that run a lot of automations. One run costs one execution, whether the workflow has 3 steps or 300.

Billed per workflow run, not per step: 2,500 runs for $24 a month
AI Agent node, MCP and human approval on every Cloud plan
Self-hosted Community Edition if you want your data on your own server
The catch: It is low-code, not no-code: expect to read JSON and debug expressions. And the license is fair-code, not open source.

2of 7

Activepieces

No-code, open source

Best for small teams that want a free start and a way out to self-hosting. A free plan with agents, a $20 plan, and one credit per run.

Free forever plan: 1,000 credits a month, 5 users, no card
One credit per run however many steps; $20 buys 10,000
Open-source edition you can run on your own servers
The catch: The catalog is smaller (770+ apps) and the self-hosted Community Edition leaves out Agents and Chat.

Make

No-code

Best for visual thinkers on a budget. The cheapest hosted way to wire 3,500 apps together, with agents on every plan.

Free plan with 1,000 credits a month; Core is $16 a month in the US
3,500+ apps and a canvas that shows the whole scenario
Make AI Agents on every plan, with your own LLM key if you prefer
The catch: Every module action burns a credit, so a chatty 10-step scenario costs 10 times what it does on a per-run tool. Agents are still labeled beta.

4of 7

Zapier

No-code

Best for non-technical teams that need one specific app. If an app exists, Zapier probably connects it: 9,000+ of them.

9,000+ apps, the largest catalog in this comparison
Free plan with 100 tasks a month, and a 14-day Professional trial
Zapier Agents with a free tier of 400 activities a month
The catch: You pay per action, AI steps can use more tasks, and Agents are a separate add-on with their own meter.

5of 7

StackAI

No-code

Best for regulated companies with an IT team. A capable free tier, then nothing self-serve until an enterprise quote.

Free plan with 500 runs a month to try the builder
Human review steps and knowledge bases built in
On-prem and VPC deployment, SOC 2 and HIPAA on Enterprise
The catch: There is no paid plan between Free and Enterprise: one seat and two projects, or a sales call.

8.8/10Very goodSee plans at StackAI

6of 7

Dify

Low-code, source-available

Best for technical teams building AI apps around their documents. Workflows, agents and a knowledge base, on Dify Cloud or your own Docker host.

Free Sandbox plan, and a self-hosted Community Edition
Knowledge bases with document processing built in
Every app publishes as a web app or an API
The catch: Professional starts at $59 a month for 3 members, and the license forbids reselling it as a multi-tenant service.

7of 7

Microsoft Copilot Studio

Low-code

Best for companies already running on Microsoft 365. The obvious pick inside a Microsoft tenant, and a detour outside one.

Agents grounded in Microsoft 365, Dataverse and Azure AI Search
Published credit rates: 1 to 10 credits per answer or action
Pay-as-you-go with no upfront commitment
The catch: A credit pack is $200 a month, and you need a Microsoft tenant and an Azure subscription before you build anything.

Which one should you choose?

Long workflows, a technical person on the team: n8n. One execution per run, and a self-hosted edition.
No code and the lowest entry price: Make, from $16 a month in the US, with a real free plan.
A rare app in your stack: Zapier, with 9,000+ apps.
Per-run pricing without the learning curve: Activepieces, free for 1,000 credits a month.
Everything already runs on Microsoft 365: Copilot Studio, if an admin can handle Azure and licensing.

Questions about ai automation tools

What are AI automation tools?

Software that connects your apps and runs multi-step workflows in which some steps are handled by an AI model or an agent: classifying, summarizing, drafting or deciding what to do next.

What is the difference between workflow automation and an AI agent?

A workflow follows fixed steps and gives the same result for the same input. An agent chooses which step or tool to use. The tools here let you combine both: fixed steps where you can define them, an agent where judgment is needed.

Which AI automation tool is cheapest?

At entry, Make ($16 a month in the US) and Activepieces ($20), both with free plans. For long, frequent workflows, tools that bill per run (n8n, Activepieces) usually cost less than tools that bill per action.

Are there free AI automation tools?

Yes: Make, Zapier, Activepieces, Dify and StackAI have free plans, and n8n has a free self-hosted edition. See free AI agent builders.
