AI Guardrails for n8n Workflows
One HTTP Request node. Plain-English rules. Catch bad AI outputs before they reach your client's customers, CRM, or inbox — without touching a line of code.
Free plan: 500 monitored outputs per month · No credit card required
The gap n8n can't fill
n8n made AI automation easy. That created a new problem.
Your workflow runs perfectly — the API call succeeds, the data flows, the next node fires. But the AI said something wrong. A customer gets a refund offer you never approved. A support reply goes out with the wrong product name. An invoice summary has a made-up number. n8n can't catch that. Tracira can.

Pass — workflow continues✕ Flag — you review first
Everything you need
Built for n8n builders, not data scientists
Slack & email alerts
Get notified the moment a bad output is detected. See the full context — project, task, explanation — without leaving Slack.
IF node branching
Use sync mode to get the verdict back inline. Connect an IF node to route your workflow: pass continues, flagged triggers an alert or stops the chain.
Quality dashboard
See pass/fail rates by project over time. Spot which n8n workflows are degrading and which AI models perform best.
Works with any AI node
OpenAI, Anthropic, Ollama, or any model accessible from n8n. Tracira evaluates the output text — not the model or the node.
Human-in-the-loop
Pause your workflow and wait for a human to approve before n8n continues. Review and decide from the Tracira dashboard.
Setup in minutes
Three steps. One HTTP Request node.
No new tools to learn. Tracira slots into n8n as a single HTTP step after your AI node.
1
Add an HTTP Request node after your AI step
Copy your Tracira webhook token from Integrations. In your n8n workflow, add an HTTP Request node right after your AI node. Set the URL to the Tracira webhook and add your token as an Authorization: Bearer header.
2
Define rules in plain English
Tell Tracira what to look for: "must mention the return policy", "must not offer a discount over 15%", "response must be under 200 words". No regex, no code.
3
Get alerts — or branch on the verdict
Tracira evaluates every output instantly. It posts a Slack alert on failures, or returns the verdict inline so you can use an IF node to branch your n8n workflow based on pass or flagged.
DefaultAsync mode — n8n keeps running instantly
HTTP Request node config
URL …/api/logs
Method POST
Header
Authorization: Bearer wh-…
Body (JSON)
"project": "Support Replies"
"output": "{{ $json.output }}"
Instant response (milliseconds)
{
"ok": true,
"id": "b1c2d3…",
"status": "pending"
}
n8n continues immediately. Tracira evaluates in the background and fires your outbound webhook when done.
SyncSync mode — get the verdict inline, branch with an IF node
Add "sync": true to body
Body (JSON)
"project": "Support Replies"
"output": "{{ $json.output }}"
"sync": true
Verdict in response — use IF node to branch
{
"status": "pass" | "flagged" | "error"
"verdict": "All rules passed."
"id": "b1c2d3…"
}
Add an IF node after the HTTP Request node. Condition: {{ $json.status }} = pass → continue. Else → alert or stop.
Outbound webhook events
Configure a URL in Integrations. Tracira POSTs to it whenever a selected event fires. Chain it into another n8n workflow or any HTTP endpoint.
