Log Explorer (Legacy) is billed on the volume of logs ingested and stored, measured in gigabytes (GB). Your charges scale with the amount of log data you choose to retain.
Unlike query-based billing models, charges are not based on how often you search or scan your data. Once logs are ingested and stored, you can query them without additional cost.
Log Explorer is available as a paid add-on for any Application Services or Zero Trust purchase. There is no free version or trial available at this time.
Billing is strictly consumption-based, calculated by the GBs ingested and stored.
Because these datasets are used for forensics, attack traffic is considered valuable data for analysis and is included in your billable usage.
To estimate your usage, review your request volumes in Analytics for specific Cloudflare log datasets.
The following table provides average and maximum record sizes for each dataset to help you estimate potential storage needs:

Cloudflare provides three primary ways to track your consumption and maintain financial oversight:
- In-product quick indicator: View your current month's usage at the top of the Log Search and Manage Datasets sections.
- Account-level billing: Access a detailed view of current and previous months' cumulative usage under Manage Account > Billing.
- Usage alerts: Set up automated notifications to trigger when billable usage exceeds a defined threshold.
- Log in to the Cloudflare dashboard ↗︎ and select Manage account.
- Go to Notifications > Add.
- Select Usage-based Billing.
- Define your threshold and the notification destination (email, PagerDuty, or webhooks).
To stop using Log Explorer and end associated charges, you must complete both of the following steps:
Disabling datasets stops additional ingestion charges immediately.
- Go to the Manage datasets ↗︎ page at the account level.
- Use the toggle to turn off each dataset you no longer need.
- Select Stop ingesting logs to confirm.
This prevents the subscription from renewing at the next billing cycle.
- Go to the Billing ↗︎ page.
- In the Subscriptions tab, find the Log Explorer subscription and select Cancel.
