bore is a simple, fast CLI tool written in Rust that creates TCP tunnels to expose local ports to a remote server, bypassing NAT and firewalls. It is a minimal, unopinionated alternative to ngrok and localtunnel, consisting of a single binary for both client and server that is easy to self-host.

Use cases

• expose a local development server to the public internet
• share a localhost web app with a teammate for testing
• test webhooks that require a publicly reachable URL
• forward a TCP port through NAT or a firewall
• self-host my own tunnel server instead of using ngrok
• demo a locally running service to a client

When to choose

• you need a lightweight, fast TCP tunnel with minimal dependencies
• you want to self-host your own tunnel server with a single binary
• you prefer a simple, unopinionated tool without accounts or dashboards
• you need cross-platform support including Docker images

When to avoid

• you need HTTP-level features like custom domains, authentication, or request inspection
• you want a GUI dashboard or traffic analytics
• you need built-in TLS termination or load balancing
• you require UDP forwarding
