What is it?

Drip is a tunneling tool that lets you publish a service running on localhost to the internet. Instead of routing traffic through a third-party relay, you run the server component on your own infrastructure and point it at a domain you control, so traffic stays between your client and your server.

The CLI supports HTTP tunnels with optional custom subdomains, so a local port can be reached at a name like myapp.your-domain.com. Recent updates added per-tunnel bandwidth limiting using a token bucket, with the server enforcing the lower of client and server limits, and bearer token authentication for controlling tunnel access.

The project is written in Go and is configured through a CLI setup command and a server config file. Its topics cover TCP, WebSocket, HTTP/2 and TLS, and the docs describe installation, basic tunnels and server deployment.

Key features

  • 01Exposes local HTTP services under your own domain or subdomains
  • 02Runs the server on your own infrastructure with no third-party relay
  • 03Per-tunnel bandwidth limiting using a token bucket
  • 04Bearer token authentication for tunnel access control
  • 05Separate transport configuration for service and tunnel domains

Use cases

  • Sharing a local development server with teammates or clients for testing
  • Exposing a self-hosted app or webhook receiver from a home network
  • Testing webhook integrations that need a public HTTPS endpoint
