Instant Local Tunneling

Share your localhost instantly.

Expose your local development environment to the internet with a single command. No networking knowledge required. No account needed to start.

$ npx --yes localtolink@latest

Capabilities

Built for the modern development workflow.

01

Zero Configuration

LocalToLink automatically detects your running application, establishes a secure tunnel, and assigns a public URL. No reverse proxies, no port forwarding, no firewall rules.

02

AI-Agent Ready

Output machine-readable JSON with the --json flag. Perfect for integration with Cursor, Claude, and automated CI/CD pipelines.

03

Full Protocol Support

Seamlessly handles HTTP, HTTPS, WebSockets, and streaming. Your local app behaves exactly as it would in production.

04

Enterprise-Grade Security

Connections are encrypted in transit (HTTPS/WSS). Automated abuse prevention and isolated sessions ensure your tunnel remains secure and reliable.

05

Resilient by Design

Network drops happen. LocalToLink automatically reconnects and resumes your exact public URL without interrupting your workflow or requiring a restart.
