An AI step is easy. Trusting the whole workflow takes more.
Zapier, Make, n8n and Workato all offer AI steps. Compare how each platform handles output checks, review, identity, policy and hosting.

Seven questions to ask of any AI step
Barndoor Automations | Zapier App automation | Make Visual scenario automation | n8n Source-available workflow automation | Workato Enterprise iPaaS | |
|---|---|---|---|---|---|
The AI step What the model can see and reach | A scoped session: only the context you pass and the tools you enable for that step. On Barndoor, only what your policy allows. | AI by Zapier steps can use selected models, knowledge and app actions as tools. | AI agents can call modules, scenarios and MCP tools inside a scenario. | AI Agent and Guardrails nodes the builder adds and wires together. | AI by Workato actions and Agent Studio genies can be used in recipes. |
Output contract Checked before anyone trusts it | Give a session a schema, and Frags validates the model's answer before the next step, or the caller, trusts it. A run that can't meet it stops and says so. | AI by Zapier supports typed output fields that you can mark as required. They are configured in the Zap editor. | AI agents can return a defined data structure; scenarios can also declare typed inputs and outputs. | A Structured Output Parser node can enforce a declared JSON schema on an agent's response. | AI by Workato can extract named fields; Agent Studio can return structured output matching configured fields. |
What you review The thing that actually runs | One FML file, written from plain English, diffed in a pull request and checked before it runs. | Built in the Zap editor, by hand or from a prompt in your AI tool. | Built on a canvas, by hand or with Maia. Scenarios export as JSON. | Built on a canvas, by hand or with the AI builder. Workflow history and Git-based environment promotion are available; the definition is JSON. | Built in the recipe editor, by hand or with AIRO. Recipes move between environments as packages. |
What the caller gets Over API or MCP | JSON in the shape the Blueprint declares, over API or MCP. | A webhook can start a Zap, but its response is not the Zap's final result. Zapier MCP exposes connected app actions. | Defined scenario outputs can be returned through the API or Make MCP server when a Return output module is configured. | Whatever the last node returns, over a webhook or the MCP Server Trigger. | API recipes can return a response with a defined schema through Workato's API platform. |
Whose identity it runs as Step by step | On Barndoor: the person who starts or schedules it. A step that needs more access runs as a service account the Blueprint names, for that step only. | App actions use the connections configured for the Zap or MCP tool. | Usually the connections of whoever built the scenario. | Nodes use the credentials configured for the workflow, which can be shared within a project. | Verified user access uses an end user's credentials in supported Workflow apps recipes and Agent Studio skills; other actions use configured connections. |
Policy and audit Every model and tool call | On Barndoor: policy checks every model and tool call, and each run gets one audited record of every call, with cost. | Enterprise app and action policies, model restrictions and optional tool approvals; AI tool use can be reviewed after a run. | Team and organization roles govern access. Scenario modules and connected accounts determine what a run can do. | Project roles and SSO on paid plans. Per-step controls are nodes the builder adds. | Enterprise controls cover recipes and connections. Agent Studio limits available skills and logs genie activity. |
Where it runs Your infra, your model | Our cloud, or the open-source Frags runtime in your VPC or on premises, with the model you choose. | Zapier's cloud. | Make's cloud. | n8n's cloud, or a self-hosted install of the whole platform. | Workato runs and manages the platform, including its dedicated Virtual Private Workato option. On-prem agents connect private systems. |
The AI step
What the model can see and reach
BARNDOOR AUTOMATIONS
A scoped session: only the context you pass and the tools you enable for that step. On Barndoor, only what your policy allows.

Output contract
Checked before anyone trusts it
BARNDOOR AUTOMATIONS
Give a session a schema, and Frags validates the model's answer before the next step, or the caller, trusts it. A run that can't meet it stops and says so.
ZAPIER
AI by Zapier supports typed output fields that you can mark as required. They are configured in the Zap editor.
MAKE
AI agents can return a defined data structure; scenarios can also declare typed inputs and outputs.
N8N
A Structured Output Parser node can enforce a declared JSON schema on an agent's response.
WORKATO
AI by Workato can extract named fields; Agent Studio can return structured output matching configured fields.

Step by step
BARNDOOR AUTOMATIONS
On Barndoor: the person who starts or schedules it. A step that needs more access runs as a service account the Blueprint names, for that step only.

Usually the connections of whoever built the scenario.
N8N
Nodes use the credentials configured for the workflow, which can be shared within a project.

Policy and audit
Every model and tool call
BARNDOOR AUTOMATIONS

Enterprise app and action policies, model restrictions and optional tool approvals; AI tool use can be reviewed after a run.
MAKE
Team and organization roles govern access. Scenario modules and connected accounts determine what a run can do.
N8N

Rows marked “On Barndoor” describe Barndoor Automations running on the Barndoor AI gateway. On the standalone product, Blueprints are shared with named users who sign in with OAuth, every run is kept in execution history, and SSO, SAML and audit logs are coming soon on Enterprise. Competitor rows are based on each vendor’s public documentation as of September 28, 2026. Product names are trademarks of their respective owners.

vs. Zapier
The workflow as source
Zapier supports typed output fields in AI steps. A Blueprint keeps the output schema, tool scope and workflow together in one file you can review in Git.
Comparevs. Make
One file to review
Make supports structured agent responses and scenario outputs. A Blueprint puts inputs, tools and the output schema in one file you can review in a pull request.
Comparevs. n8n
Checks in the source
n8n offers AI Agent, parser and Guardrails nodes. A Blueprint declares context, tools and an optional output schema in the same file as the workflow.
Comparevs. Workato
A source file and your runtime
Workato has enterprise controls and structured AI output. A Blueprint gives you one reviewable FML file and an open-source runtime you can operate yourself.
