Frequently asked questions

What are seats?

Seats determine the maximum number of workers who can use Cerb at the same time.

For example, a team of 30 workers who are evenly split into three, non-overlapping shifts (morning, day, night) would only require 10 seats. That's the highest number of workers who would ever be logged in at the same time.

You aren't paying per worker account, so there isn't a penalty for inviting everyone to participate: full-time staff, part-time contributors, busy executives, interns, temps, contractors, partners, and volunteers.

Do you provide academic discounts?

Yes. We offer a 50% discount in support of academic institutions.

To qualify for an academic discount, institutions must be accredited by an agency recognized by the U.S. Department of Education (or their own national equivalent). All publicly funded K-12 and preschools automatically qualify.

Do you offer a discount to charities and non-profits?

Yes! To receive a free Cerb license with more than one seat, a charity or non-profit must have a charter that seeks to improve the public good and be registered as a 501(c)(3) organization (or their own national equivalent). The organization should be primarily funded through public donations or grants, and such contributions should be tax-deductible by the donors.

What qualifies an open source project for a free license donation?

To receive a free Cerb license with more than one seat, an open source project must have:

  • A website explaining the purpose of the project
  • 100% source code available in a public repository like GitHub
  • A self-hosted option with an open source or fair-code license

An open source license must only be used for that purpose, and must not be mixed with other commercial activity.

Can I migrate between self-hosted and Cerb Cloud?

Yes! You can migrate your data between self-hosted and Cerb Cloud at any time. They are 100% compatible and the subscriptions are interchangeable.
