A simple ngrok alternative for exposing localhost

Need a public HTTPS URL for localhost? You probably do not need an API gateway. tunnel.to gives your local app, webhook receiver, MCP server, development server, or self-hosted service a secure public URL.

No account required. No auth token to configure. No inbound ports. No firewall rules. No free-tier browser warning.

tunnel.to vs ngrok

ngrok is a mature platform that has grown beyond localhost tunneling into ingress and API delivery, with traffic policies, authentication, load balancing, WAF capabilities, Kubernetes integration, and production infrastructure features. Those are valuable when you need them.

tunnel.to is focused on a smaller job: make this local service reachable from the internet.

From localhost to a public URL in one command

Suppose your application is running at http://localhost:3000. Run tunnelto 3000 and tunnel.to creates a public HTTPS endpoint that forwards traffic to your local service.

Public HTTPS request
https://your-tunnel.tunnel.to
tunnel.to
http://localhost:3000
Your local application

There is no router configuration, port forwarding, public IP address, or inbound firewall rule required.

No account required

Install the client and immediately create a temporary tunnel. There is no account or auth token to configure before the first request reaches your app.

  • Quick development tests
  • Share a local application
  • Test webhook callbacks
  • Expose a temporary API
  • Develop AI agents and MCP servers
  • Run demos and prototypes

If the experiment becomes something you want to keep, create a free account for a reserved hostname. Upgrade when you need a custom domain, tunnel protection, or more capacity.

Start disposable. Make it permanent when it matters.

No free-tier browser warning

A public tunnel often is not meant for a person. Webhook providers, OAuth callbacks, API clients, agents, and automation platforms need to reach the endpoint directly.

tunnel.to does not insert a browser warning or interstitial in front of Anonymous or Registered Free tunnels. Your public URL points to your application.

Built for webhooks

Keep your webhook handler, debugger, and logs on your machine. Give the generated HTTPS URL to the provider and receive callbacks directly in your local application instead of redeploying after every change.

Built for MCP and local AI development

An MCP server, agent endpoint, callback handler, or local AI application can stay on your machine while a remote service connects through tunnel.to.

AI service
https://your-tunnel.tunnel.to
tunnel.to
localhost:3000
Your MCP server or agent

You do not need to deploy the project to a VPS just to make it reachable during development.

Server-Sent Events work too

tunnel.to carries long-lived Server-Sent Events connections for AI streaming, MCP transports, live status, notifications, progress events, and other event streams. There is no special SSE mode to enable.

Both tunnel.to and ngrok can carry SSE traffic. When the requirement is simply expose my local SSE endpoint, tunnel.to keeps the setup focused.

Use your own domain when you are ready

Temporary URLs are ideal for experiments. A paid plan lets you attach a domain such as hooks.example.com or mcp.example.com to a reserved tunnel when the endpoint becomes permanent.

Protect your tunnel

Not every public URL should be open to everyone. Paid plans add built-in tunnel authentication for development tools, dashboards, prototypes, and internal applications that still need a convenient public HTTPS endpoint.

Simple tunnels. Simple pricing.

Start anonymously with 512 MiB per tunnel, or create a Registered Free account for a reserved hostname and 5 GB of bandwidth per month. Upgrade when you need custom domains, protected tunnels, more names, or more capacity.

When should I use ngrok instead?

ngrok may be the better choice when your requirements extend beyond a straightforward public tunnel into sophisticated production ingress infrastructure.

  • Advanced traffic policies
  • Edge OAuth, OIDC, or SAML
  • Web application firewall controls
  • Request and response transformation
  • Traffic inspection and replay
  • Load balancing and enterprise ingress
  • Advanced Kubernetes integration

If the requirement is simply I have something running on localhost and I need a public HTTPS URL for it, that is exactly what tunnel.to is built to do.

Frequently asked questions

What is an ngrok alternative?

It is another service or tool that creates a public endpoint for an application otherwise reachable only locally or privately.

Can I expose localhost without creating an account?

Yes. tunnel.to supports anonymous tunnels.

Does tunnel.to show a browser warning on free tunnels?

No. Anonymous and Registered Free tunnel URLs route directly to your application without a tunnel.to interstitial page.

What are the free bandwidth limits?

Anonymous tunnels include 512 MiB per tunnel. A Registered Free account includes 5 GB of bandwidth per UTC calendar month.

Does tunnel.to support custom domains?

Yes. Paid plans can attach custom domains to reserved tunnel names.

Do I need to change firewall rules?

No. The tunnel client establishes an outbound connection to make the local service reachable.

When should I choose ngrok instead?

Choose ngrok when you need a broader production ingress platform with capabilities such as advanced edge policies, WAF controls, enterprise authentication, traffic replay, load balancing, or Kubernetes integrations.

Get localhost online.

No account. No auth token. No inbound ports. Just a public HTTPS URL pointing to localhost.
