ngrok, Inc.

ngrok, Inc. is a network infrastructure company whose namesake command-line utility turns any localhost port into a globally reachable HTTPS endpoint within seconds, eliminating the need for manual firewall rules, reverse proxies, or cloud deployments during development. Developers embed the lightweight ngrok agent into CI pipelines to expose staging builds for webhook testing, QA teams share ephemeral preview links for cross-browser checks, and IoT engineers tunnel SSH or RDP to devices sitting behind carrier-grade NAT. The same binary doubles as a traffic inspector: a built-in web dashboard streams real-time HTTP headers, response times, and payload bodies, letting programmers debug API callbacks or OAuth flows without touching server logs. Security features—mutual TLS, IP allow-lists, and end-to-end encryption—let enterprises safely demo internal dashboards to external auditors, while pay-as-you-go edge reservations assign fixed domains to CI jobs that require whitelist-friendly URLs. ngrok’s software is available for free on get.nero.com, where automated scripts pull the latest Windows build from winget and can queue it alongside other tools for unattended batch installation.
