Traffic Policy Unit (TPU) Pricing
Traffic Processing Units (TPUs) are ngrok's usage-based unit for measuring how much processing your traffic policies perform. Instead of charging per request or connection, ngrok charges based combined cost of the actions, variables, and macros you use.
TPUs are sold in bundles of 100,000 for $1, and are deducted as your policies run.
Actions, Expressions, and Variables
- Actions: Define what happens when a traffic policy rule matches (e.g. add headers, deny a request, forward traffic).
- Expressions: Conditions (written in ) that determine whether actions execute, based on request or connection properties.
- Variables: Metadata about connections or requests that you can use in expressions or actions (e.g. client IP, headers).

Traffic Policy Unit (TPU) discounts at scale
The Pay-as-You go plan discounts TPUs at a large scale, so you don't have to talk to sales tog et a pricepoint that grows as you grow. Discounted pricing is as follows:
| Count | TPU Cost |
|---|---|
| 0+ | $1/100k |
| 1M+ | $.75/100k |
| 10M+ | $.55/100k |
| 100M+ | $0.35/100k |
| 1B+ | $0.25/100k |
