n8n Tunnel Service Discontinued

The discontinuation of the n8n Tunnel Service and the related --tunnel option is due to operational difficulties and security concerns, with the service already removed in n8n v2 and remaining only as legacy support for n8n v1. Users who previously relied on this service for exposing locally running n8n instances to the public internet for webhook development are encouraged to switch to third-party tunneling services such as Cloudflare Tunnel, ngrok, or localtunnel, which offer various free and paid options to forward public traffic to local n8n ports. It is crucial to treat local webhook endpoints with the same security considerations as production entry points, including verifying signatures, using secrets, and minimizing exposure time. Additionally, n8n invites users to share their projects for community inspiration, reflecting the diverse backgrounds and interests of its user base.
