Features

• Every protocol. HTTP, TCP, and TLS tunnels. Every HTTP tunnel gets a real certificate that browsers trust, issued automatically.
• Private by design. Localport never inspects or logs the plaintext of your traffic, and every tunnel stays pinned to the region you choose.
• Locked tunnels. Mutual TLS restricts a tunnel to devices holding a certificate you issued, verified on every request and revocable the instant you need it (ECDSA P-256).
• Access control. IP allowlists and password protection in front of any tunnel.
• Reserved addresses. Static subdomains and reserved ports keep your public URLs and webhook endpoints stable across restarts.
• Mesh. Address an entire fleet by name. Each device gets its own subdomain, port, and protocol, and stays reachable behind NAT, CGNAT, or cellular.
• Shared tunnels. Deliver one inbound request to every connected client at once, with a designated client returning the response.
• Works anywhere. Connects through NAT, CGNAT, and corporate firewalls with no router changes.
• Cross-platform. Prebuilt binaries for macOS, Linux, and Windows.
