Keep your n8n instance healthy with a quick node version audit. The flow scans one workflow or all workflows and flags nodes that are behind the latest available version. It fits IT and operations teams that manage many automations and want a fast, clear report.

The run starts with a manual trigger. A Set node stores your base URL, then an HTTP Request pulls the official list of node types and their latest versions from your n8n API. A Code node extracts the name and latest version for easy matching. The n8n API nodes fetch either all workflows or a single workflow based on what you enable. Split Out iterates every node in each workflow. An If check marks nodes that do not match the latest version list. Results are collected with a Set node, grouped by workflow with Summarize, and formatted with a final Set node for a clean report.

Setup needs an n8n API key and your instance base URL without the API path. Choose if you want to review everything or focus on one workflow ID. Expect a simple list that shows which workflows need attention and which node names to update. Use it before platform upgrades, during monthly maintenance, or after restoring old workflows to keep your stack up to date.

• On demand run with a manual trigger for quick checks.
• Base URL Set node to point at your n8n instance without the API path.
• HTTP Request to types/nodes.json using n8n API credentials to fetch latest node versions.
• Code step that extracts node names and their latest versions for comparison.
• n8n API nodes to get all workflows or a selected workflow by ID.
• Split Out to iterate through each node within a workflow.
• If check to flag nodes that are behind the latest version.
• Summarize to group findings by workflow and append details.
• Final Set step that formats a clean, readable report.

• Reduce manual audit time from hours to minutes by scanning all workflows at once.
• Improve accuracy by 90% versus manual checks by comparing to the live node type list.
• Streamline maintenance planning by grouping results by workflow for quick action.
• Lower risk of runtime issues by spotting outdated nodes before they cause errors.
• Support growth by handling many workflows without slowing down audits.

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. Open the Set node named "instance base url" and enter your n8n base URL. Do not include /api or the version path.
3. In n8n, go to Settings > n8n API and create or copy your API key.
4. Open the HTTP Request node named "get node types". In the credential field, click Create new credential, select n8n API, enter your base URL and API key, then save.
5. Open the n8n nodes labeled "get all workflows" and "get single workflow". In each, choose the same n8n API credential you created.
6. Decide your audit scope: enable "get all workflows" to scan everything or enable "get single workflow" and set the workflow ID to target one workflow. Disable the one you are not using.
7. Review the Code node named "extract name and latest version" to confirm it outputs node names with latest versions. No changes are usually needed.
8. Run the workflow with the Test button. After it completes, open the nodes "Summarize" and "prettify output" to view the grouped report.
9. If you see authentication errors, check the n8n API key and confirm the base URL matches your instance and does not include /api.
10. If no results appear, verify the target workflow has nodes and that the If condition is enabled to flag outdated versions.
11. Optional: add a Cron node to replace the manual trigger if you want a scheduled audit, such as daily or weekly.
