Terms of Service

Last updated: October 2026

ABMeter is free to use. By using ABMeter, you agree to the following:

  • No warranties. ABMeter is provided "as is" without warranties of any kind, express or implied. Features may change, data may be reset, and service availability is not guaranteed. ABMeter shall not be liable for any damages arising from your use of the service.
  • Usage limits. Accounts have these limits by default. The demo space does not count toward them.
    • 100 active experiments at a time. An experiment is active while it runs and after it stops, until you archive or reset it. At the limit, archive or reset one to start another.
    • 100 enabled feature flags at a time. At the limit, disable a feature flag to enable another.
    • 500,000 active items per calendar month (UTC). An active item is an event or exposure that an experiment or feature flag influenced. At the limit, the API rejects new events and exposures until the 1st of the next month.

    Your current usage is on your Usage page. If a limit blocks a real experiment, let us know.

  • Data retention. ABMeter deletes events and exposures older than 90 days. The deletion runs once a day.
