See where your
workflow needs care.
A free n8n workflow checker for structural gaps and reliability risks. Select an exported workflow definition to get specific evidence, repair priorities, and a test plan.
Your workflow stays in this browser. It is not uploaded, saved, or sent to an API. Imported workflow text is treated as sensitive. Static findings cannot prove runtime failures.
STEP 01 / IMPORT
Choose an n8n workflow JSON
Export a workflow definition from n8n. Maximum file size: 5 MB.
No workflow selected.
STEP 02 / REVIEW
Your workflow report
Prioritized findings
This is a static review of the imported definition. POTENTIAL_RISK findings are hypotheses. No workflow code ran and no runtime execution history was inspected. Review sensitive values before sharing an exported report.
WHAT THIS CHECKER CAN TELL YOU
Evidence first. Useful next steps.
Surfaces potential retry, duplicate-processing, recovery, input-validation, HTTP, and credential risks for review.
Download findings, a prioritized checklist, and suggested normal and failure-path tests as Markdown or JSON.
A static workflow export does not show whether an execution failed, whether a credential works, or what external systems returned. Findings clearly distinguish confirmed exported structure from potential risk and insufficient evidence.
