MTUs (Monthly Tracked Users) are all the unique user profiles sent to Chameleon from your account within the last 30 days. We use MTUs to count users within Chameleon Experiences and determine monthly costs.
ℹ Accounts created before March 28, 2021, use MAUs (Monthly Active Users) for billing instead. Learn more about the difference between MTUs and MAUs.
How we bill MTUs
Chameleon starts counting MTUs once the code snippet is successfully installed. Our infrastructure costs scale with the data you store and manage, so your monthly cost scales with your MTUs.
We charge based on the maximum number of MTUs in each billing period. We don't aggregate users historically, just users seen in the last 30 days.
ℹ The MTU count is based on users with a "last seen time" within the last 30 days.
You can monitor your current count from the Billing page.
What if your MTUs exceed your plan limit?
How overages work depends on your plan.
Pro plan
On the Pro plan, your monthly cost scales with your MTUs through graduated tiers. If your MTUs grow into a higher tier in a given month, your next invoice reflects the new tier.
Growth and Enterprise plans
On the Growth and Enterprise plans, your contract includes a set MTU allowance. If your account goes over that allowance in a given month, the overage appears on your next invoice. Annual billing doesn't lock in your MTU usage. If your account exceeds your contract allowance in a given month, the overage appears on your next invoice.
Startup plan
If you are currently on a Chameleon Startup plan, your monthly pricing is based on your MTUs. If you exceed the limit set in your plan, Chameleon will charge you a standard price based on the MTU overages for that month.
Why MTUs might exceed your plan
Even with steady usage, a few changes can push your MTUs higher than expected:
Installing Chameleon in a new product. If you add Chameleon to a second or third product, your MTU count includes all users from each. If your current allowance doesn't cover this, contact us to recalculate.
Installing Chameleon on a marketing site. Marketing site visitors get counted toward MTUs. You can limit your Chameleon installation to a subset of users to avoid this.
Changing how you identify users. Inconsistent identification (e.g., anonymous users sent as unique IDs) inflates MTU counts. Make sure each user is identified consistently across sessions.
👉 Keep up with your monthly MTUs from your Chameleon Dashboard.
How to prevent overages
If you expect changes to your account (organic growth, installing Chameleon in different products, domains, etc.), reach out to us to review your plan. It will be easier and less costly to adjust to your changing needs than pay overages.
