🌐 Introduction

Modern development workflows require more than just writing code—you need to test APIs, webhooks, and real-time integrations in a live environment. But what if your app is running locally on localhost?

How do you:

• Test webhooks from external services?
• Share your local project with clients?
• Debug APIs in real-time?

This is where NowMail Tunnel comes in.

Similar to tools like Ngrok, NowMail Tunnel allows you to expose your local server to the internet using a public URL like:

https://api.blog.rock.nowmail.in

or even wildcard-based subdomains like:

*.rock.nowmail.in

In this blog, we’ll explore how NowMail Tunnel works, why it matters, and how it can supercharge your development workflow.

🔍 What is NowMail Tunnel?

NowMail Tunnel is a secure tunneling service that creates a bridge between your local machine and the public internet.

👉 It maps your local server:

http://localhost:3000

👉 To a public URL:

https://your-app.rock.nowmail.in

This means anyone with the URL can access your local app in real-time.

⚙️ How NowMail Tunnel Works

NowMail Tunnel works using a combination of reverse proxy, secure tunnels, and subdomain routing.

Step-by-Step Flow:

1. Tunnel Client Starts

You run a command like:

nowmail-tunnel --port 3000

2. Secure Connection Established

Your system connects to NowMail servers via a secure channel (TLS).

3. Public URL Generated

NowMail assigns a public URL:

https://myapp.rock.nowmail.in

4. Request Forwarding

When someone visits the URL:

• Request goes to NowMail server
• Forwarded to your local machine
• Response sent back to user

👉 All this happens instantly.
