Four open-source command-line tools lint, mock, test, and render n8n workflow JSON.

Landing page captured for the 2026-09-23 issue.

For: People building and maintaining n8n workflows
Worth noticing: The mock tool can simulate failures and delays across Slack, Stripe, HubSpot, and 23 other services, without API keys.

Field notes

The four tools are presented as separate npm commands, with Node 20 required for integration-mock and Node 24 for workflow-lint and workflow-tester. The renderer's browser demo lets visitors paste workflow JSON; the page says that data stays in the browser. It also lists GitHub Actions, pre-commit, and Claude Code/Cursor integrations.
