Secure tunnels to localhost
”I want to expose a local server behind a NAT or firewall to the internet.”
Demo without deploying
Don’t constantly redeploy your in-progress work to get feedback from clients. ngrok creates a secure public URL (https://yourapp.ngrok.io) to a local webserver on your machine. Iterate quickly with immediate feedback without interrupting flow.
Simplify mobile device testing
Test mobile apps against a development backend running on your machine. Point ngrok at your local dev server and then configure your app to use the ngrok URL. It won't change, even when you change networks.
Build webhook integrations with ease
Building webhook integrations can be a pain: it requires a public address and a lot of set up to trigger hooks. Save yourself time and frustration with ngrok. Inspect the HTTP traffic flowing over your tunnel. Then, replay webhook requests with one click to iterate quickly while staying in context.
Run personal cloud services from your own private network
Own your data. Host personal cloud services on your own private network. Run webmail, file syncing, and more securely on your hardware with full end-to-end encryption.
Need to run ngrok in production? Use ngrok link to manage your IoT devices or as a lightweight alternative to VPN for targeted access into customer networks.
