Definitions for every feature and metric that appears in the [ngrok pricing docs](/pricing-limits/). ## Online endpoints The number of endpoints you can have online at the same time. [Learn More](/gateway/agent-endpoints/) ## Development endpoint hours Public endpoints started with your development domain do not accrue endpoint hours. [Learn More](/pricing-limits/#limits-and-licensing) ## Active endpoint hours An endpoint is active if it has outgoing traffic during the hour. [Learn More](/pricing-limits/#limits-and-licensing) ## Endpoint protocols These are the different protocols available to you as a subscriber of each plan. [Learn More](/gateway/agent-endpoints#protocols%2C-binding-and-pooling) ## Endpoint hours The amount of time your endpoints are online. ## Load balancing Load balancing at ngrok is called endpoint pooling. [Learn More](/gateway/endpoint-pooling) ## Domains Domains you own registered in the ngrok dashboard. [Learn More](/gateway/domains/) ## Development domain Your development domain is specific to your account, and does not incur usage charges. You can use anything for free on your sandbox domain within your account's limits. [Learn More](/gateway/domains/) ## ngrok-branded domains Use any ngrok-branded domain that you pick from ngrok's pool. [Learn More](/gateway/domains/) ## Traffic Policy Units Traffic Processing Units (TPUs) are ngrok’s usage-based metric for measuring the work your Traffic Policies perform. [Learn More](/pricing-limits/traffic-policy-unit-pricing) ## Bring your own custom domains Use any custom domain name that you already own with ngrok. [Learn More](/gateway/custom-domains/) ## Wildcard Domains You can create an endpoint which will receive traffic for all of the subdomains matching a given wildcard domain like \*.example.com. [Learn More](/gateway/http/#wildcard-endpoints) ## TCP Addresses TCP Addresses enable you to create public TCP Endpoints on a fixed address. [Learn More](/gateway/tcp-addresses/) ## Data transfer out The total volume of data transferred outbound from ngrok's network to clients, including traffic forwarded to agents. [Learn More](/pricing-limits/#limits-and-licensing) ## Requests to HTTP/s endpoints The maximum number of HTTP/s requests a client can make to an account's endpoints in a month. [Learn More](/gateway/http/) ## Connections to TCP / TLS endpoints The maximum number of TCP/TLS connections a client can make to an account's endpoints in a month. [Learn More](/gateway/tcp/) ## HTTP Requests The maximum number of HTTP requests across all endpoints per minute. [Learn More](/pricing-limits/how-ngrok-charges/) ## TCP Connections The maximum number of TCP connections across all endpoints per minute. [Learn More](/pricing-limits/how-ngrok-charges/) ## Bring your own certificates Upload your own TLS certificates if you don't want to use the TLS certificates that ngrok automatically provisions for you. [Learn More](/gateway/tls/) ## End to End TLS Terminate TLS at your upstream service or at the ngrok agent to achieve end-to-end encryption. [Learn More](/gateway/tls-termination/) ## Mutual TLS Mutual TLS Authentication (mTLS) is a network security protocol that ensures both the client and server authenticate each other using digital certificates. [Learn More](/traffic-policy/) ## Traffic Policy Units (TPUs) This is a combination of the actions, macros, and variables applied to a request. WAF, mTLS, and more are included in TPUs. [Learn More](/pricing-limits/traffic-policy-unit-pricing/) ## Traffic Identities OAuth/SAML/OIDC. This is calculated by the number of end users that authenticate into your app or service via the Traffic Policy action. [Learn More](/traffic-policy/) ## Traffic Inspector Retention This is the number of hours ngrok retains your traffic data in Traffic Inspector. [Learn More](/obs/traffic-inspection) ## Traffic Log Exporting Export event logs when traffic transits through your endpoints to S3, Datadog, Azure Logs, CloudWatch Logs + more. [Learn More](/obs/) ## Concurrent Agents The maximum number of ngrok agents that can be simultaneously connected to the ngrok cloud service under a single account. [Learn More](/agent/) ## Dedicated Agent Connect IPs Get a constant, dedicated IP for your account's agents. [Learn More](/agent/) ## Custom Agent Connect URLs Customize the URL that the agent connects to. [Learn More](/agent/) ## Remote Agent Update Operations Run ngrok in the background as a service. [Learn More](/agent/) ## Users Members of your account that can view or create endpoints. [Learn More](/iam/users/) ## Service Users Service users are accounts for automated systems that programmatically interact with your ngrok accounts either by starting ngrok Agents or making requests to the API. [Learn More](/iam/service-users/) ## SSO/RBAC Federate auth to your Identity Provider (IdP) with SAML or OpenID Connect. [Learn More](/iam/sso/) ## Identity and Access Governance Suite SCIM, Domain Controls, Account-Wide IP Restrictions, Audit Logs. [Learn More](/iam/) ## Authtoken ACLs Authtoken ACLs restrict what endpoints an ngrok agent can create when using that authtoken. [Learn More](/agent/config/) ## Basic support Email support and best-effort response times. ## Slack and MS Teams Dedicated channel with 24 hour response SLA. ## Dedicated On-Call Committed/Contractual Uptime SLA and Support SLA. ## Region-specific routing Configure your domains to only route traffic through specific geographic regions. ## HIPAA / BAAs HIPAA compliance is built in: ngrok handles the BAA so you can focus on building the app. ## SOC2 Independent verification that your data is secure. ## Security questionnaires If your team requires a security questionnaire, ngrok can prepare it. ## Invoicing If your team requires an invoice for billing purposes, ngrok can send it.
