Zapier puts AI in a Zap. A Blueprint puts the workflow in code.
AI by Zapier supports typed, required output fields and tools. A Blueprint declares its workflow and optional output schema in one reviewable file; on Barndoor, identity and policy apply to each step.
Head to head
Barndoor Automations vs. Zapier, row by row
Barndoor Automations | Zapier App automation | |
|---|---|---|
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. |
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. |
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. |
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. |
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. |
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. |
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. |
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.
ZAPIER
AI by Zapier steps can use selected models, knowledge and app actions as tools.
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.
What you review
The thing that actually runs
BARNDOOR AUTOMATIONS
One FML file, written from plain English, diffed in a pull request and checked before it runs.
ZAPIER
Built in the Zap editor, by hand or from a prompt in your AI tool.
What the caller gets
Over API or MCP
BARNDOOR AUTOMATIONS
JSON in the shape the Blueprint declares, over API or MCP.
ZAPIER
A webhook can start a Zap, but its response is not the Zap's final result. Zapier MCP exposes connected app actions.
Whose identity it runs as
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.
ZAPIER
App actions use the connections configured for the Zap or MCP tool.
Policy and audit
Every model and tool call
BARNDOOR AUTOMATIONS
On Barndoor: policy checks every model and tool call, and each run gets one audited record of every call, with cost.
ZAPIER
Enterprise app and action policies, model restrictions and optional tool approvals; AI tool use can be reviewed after a run.
Where it runs
Your infra, your model
BARNDOOR AUTOMATIONS
Our cloud, or the open-source Frags runtime in your VPC or on premises, with the model you choose.
ZAPIER
Zapier's cloud.
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. The Zapier column is based on its public documentation as of September 28, 2026. Zapier is a trademark of its owner.
What changes with a Blueprint
A schema in the source
Declare an output schema beside the model step in FML. Frags validates the answer before the next step or caller uses it.
One file to review
The whole workflow is one FML file, diffed in a pull request and checked before it runs, instead of settings spread across the Zap editor.
Runs where you need it
Our cloud, or the open-source Frags runtime in your VPC or on premises, with your own model keys. A Zap runs only in Zapier's cloud.
