Pathway Licensing Terms and Conditions

Pathway comes in three offerings: Community, Scale, and Enterprise. For a product comparison, see our Features page.

Pathway Community

Pathway Community is distributed under a free and source-available license: the Pathway Business Source License (BSL), converting to the open-source Apache 2.0 license after 4 years.

This core product is free for production use, with the exclusion of providers of "Stream Data Processing Services" mentioned in the license, such as cloud hosting providers reselling products to others.

On a historical note, the BSL license originates from MariaDB, and has been adopted by companies such as CockroachDB, Redpanda, ReadySet, and numerous other organizations.

Pathway Scale

Pathway Scale is intended for demanding users who need extra features not covered by Pathway Community, or need to use more resources.

Pathway Scale is distributed under the same Pathway Business Source License (BSL) as Pathway Community. Production use of Pathway Scale can be activated in source code by using a special function (pathway.set_license_key) and requires that the user obtains a license key. License keys come in several tiers, each with different resource limits, and may be free or paid.

By using the Pathway Scale license key, you additionally acknowledge and agree that anonymized product usage data is sent to Pathway (the company) via an OpenTelemetry collector. This data helps us improve the product and provide better support. All data collected is subject to Pathway's Privacy Policy. You have the right to review Pathway's Privacy Policy to understand how your data is handled.

Pathway Enterprise

Pathway Enterprise includes extensions of Pathway functionalities particularly useful in enterprise deployments: please take a look at our feature comparison. Use of Pathway Enterprise is governed by separate commercial licenses. Do not hesitate to reach out to us for more information.

Licensed Work:
    Releases of Pathway covered by this License contain a copy of this License
    as their license file, and are made available by the Licensor at,, and by way of other distribution

    The Licensed Work is © 2024 NavAlgo SAS

Additional Use Grant:
    The Licensor grants you (the licensee) additional rights to the Licensed
    Work, whereby you are entitled to run the Licensed Work in production
    use, at no cost, subject to all of the following conditions: 

    (a) in a single installation of the Licensed Work you may run the Licensed
    Work on only one machine, physical or virtual, and without exceeding the
    number of worker threads and processes allowed by the configuration of the
    software runner of the distribution; and 

    (b) the additional right to use granted herein applies to the exclusion
    of use of the Licensed Work for a Stream Data Processing Service, as well
    as to the exclusion of use of any modified or derivative Licensed Work,
    in particular:
    - you may not move, change, disable, or circumvent any license key
    or resource limiting functionality that may be present in the software,
    and you may not remove or obscure any functionality in the software that
    is protected by the license key or circumvent resource limits,
    - you may not alter, remove, or obscure any licensing, copyright, or other
    notices of the licensor in the software; 

    (c) the production use of modified Licensed Work is permitted only where
    the modifications of the Licensed Work are indispensable to fix bugs or
    vulnerabilities which might otherwise alter the scope of functionalities
    of the Licensed Work, as described in API documentation available at; and

    (d) this entire License including its Additional Use Grant shall remain
    in full force and effect for any use under this Additional Use Grant,
    thus covering the Licensed Work and also binding any and all users of
    the Licensed Work. 
    A “Stream Data Processing Service” is defined as any offering that allows
    third parties (other than your employees or individual contractors) to
    access the functionality of the Licensed Work by performing an action
    directly or indirectly that causes the deployment, creation, or change to
    the structure of a running computation graph of Pathway on any machine.
    For the sake of clarity, a Stream Data Processing Service would include
    providers of infrastructure services, such as cloud services, hosting
    services, data center services and similarly situated third parties
    (including affiliates of such entities) that would offer the Licensed
    Work, possibly in connection with a broader service offering, to their
    customers or subscribers.
