A simple ngrok alternative for exposing localhost
tunnel.to creates a public HTTPS endpoint for an application running on your machine. Start with an anonymous tunnel and make it permanent only when you need to.
The client makes an outbound connection, so there is no inbound port to open, firewall rule to change, or server deployment to manage.
tunnelto 3000Why developers use tunnel.to
- Share a local development server
- Receive and debug webhooks
- Demo work in progress
- Expose an API or AI agent
- Make an MCP server remotely reachable
- Give a third party temporary access to a local endpoint
tunnel.to vs ngrok
| Capability | tunnel.to | ngrok |
|---|---|---|
| Public HTTPS tunnels | Yes | Yes |
| Use without an account | Yes | No; agent setup uses an account authtoken |
| Stable hostname | Reserved names | Account development domain |
| Custom domains | Yes | Yes, subject to plan and configuration |
| Product focus | Public reverse tunnels | Ingress and API delivery platform |
ngrok has evolved into a broad ingress and API-delivery platform. tunnel.to is deliberately narrower: get a local service onto a public HTTPS URL with as little ceremony as possible.

Start disposable. Make it permanent later.
