License

OttoTester is covered by the Business Source License 1.1. This page sums up what it means in plain words, then shows the full license. If the two ever seem to disagree, the license text is what counts.

In plain words

Free for real work: individual developers and testers working for themselves, and companies of 10 people or fewer, counting employees and contractors, with US $500,000 or less in revenue over the last 12 months. A company’s affiliates count toward both limits. If you work for a larger company, its trial or license covers you, not the free use for individuals.
Everyone else gets one free 30-day trial, for any use. After that, they need a license from us. Testing your own apps counts as real work. To get a license, email sales@ottotester.ai.
Nobody may offer OttoTester to others as a hosted testing service for real work, paid or free. Testing apps for your clients is fine when you run OttoTester yourself and they only get the results.
Each version becomes open source under the Apache License 2.0, four years after that version is first released.

The license

This is the same text that ships inside every copy of OttoTester. On a copy you installed with the install command, it’s the LICENSE file in your install folder, updated to match each version you move to. Global Admin → About also links to this page.

Business Source License 1.1

Parameters

Licensor:             Business Performance Systems, LLC

Licensed Work:        OttoTester. The Licensed Work is (c) 2026 Business
                      Performance Systems, LLC.

Additional Use Grant: You may make production use of the Licensed Work if
                      you are an individual or a Small Organization, and you
                      do not offer the Licensed Work to third parties as a
                      Testing Service. An individual using the Licensed Work
                      as an employee of an organization is covered only if
                      that organization is a Small Organization.

                      A "Small Organization" is one that, counted together
                      with its affiliates, has no more than 10 people working
                      for it as employees or independent contractors, and
                      had no more than US $500,000 in revenue in the previous
                      12 months.

                      Any other organization may also make production use of
                      the Licensed Work for a trial of 30 days, starting on
                      the day it first makes production use of any version.
                      Each organization, counted together with its
                      affiliates, gets one trial. The trial does not allow
                      offering the Licensed Work as a Testing Service.

                      Using the Licensed Work to create, run, repair or
                      report on tests of software that you develop, operate
                      or deliver is production use, whether or not that
                      software is itself in production.

                      A "Testing Service" is any product or service, paid or
                      free, that gives third parties access to features of
                      the Licensed Work, such as creating, running, repairing
                      or reporting on automated tests, where the Licensed
                      Work is hosted, managed or embedded by you or on your
                      behalf. Testing software for your clients is not a
                      Testing Service when you operate the Licensed Work and
                      your clients receive the results, not access to the
                      Licensed Work.

Change Date:          Four years from the date each version of the Licensed
                      Work is first publicly released.

Change License:       Apache License, Version 2.0

In consideration of the right to use this License’s text and the “Business

other recipients of the licensed work to be provided by Licensor:

1. To specify as the Change License the GPL Version 2.0 or any later version,
   or a license that is compatible with GPL Version 2.0 or a later version,
   where “compatible” means that software provided under the Change License can
   be included in a program with software provided under GPL Version 2.0 or a

The demo app

The installer can start a demo app for your first test run. The demo app is not part of OttoTester and is not covered by the license above. It has its own license, which covers only the demo app:

OttoTester demo app

The OttoTester installer can start a demo app for a first test run. The
demo app is OrangeHRM, an open-source HR app. We do not own OrangeHRM.

The demo app, including the setup files that come with it, is covered by
OrangeHRM's license: the GNU General Public License, version 3 or any later
version (GPL-3.0-or-later), in the LICENSE file next to this notice.

Those terms cover only the demo app. They do not cover OttoTester or
anything else. OttoTester is covered by the Business Source License 1.1,
in its own LICENSE file.
