The core workflow engine, standard integration nodes, and open-source SDKs of P2F are licensed under the terms of the Apache License, Version 2.0.

For organizations requiring enterprise deployment, guaranteed uptime SLAs, premium connector modules, and advanced security capabilities (such as SAML/SSO integration, custom audit logging, and isolated worker clusters), P2F offers commercial subscriptions under separate master service agreements (MSA).

• Commercial licenses grant non-exclusive access to proprietary P2F Cloud extensions.
• Enterprise features may not be redistributed or re-licensed without explicit written permission from P2F.
• Custom deployment options (On-Premises / Air-Gapped Cloud) are governed by specific enterprise contract addendums.

We welcome open-source contributions to P2F! When submitting pull requests, code patches, or documentation to P2F open-source repositories, contributors agree to grant P2F a perpetual, worldwide, non-exclusive, royalty-free license to use, reproduce, and distribute the contributed work under the Apache 2.0 License.

You retain full copyright of your original contribution while empowering the P2F community to build upon it safely.

The names "Promptoflow", "P2F", the P2F logo, and associated brand icons are trademarks owned by P2F.

P2F utilizes trusted third-party open-source libraries and modules (such as React, Next.js, Lucide Icons, and Tailwind CSS). Each component remains governed by its respective open-source license terms (e.g. MIT, BSD-3-Clause, Apache 2.0).

Full attribution and copyright notices for third-party packages are maintained within our source repository bundle notices.

When using the P2F software or platform, you agree not to:

• Remove, obscure, or modify any copyright or proprietary rights notices.
• Use P2F trademarks to mislead users into believing a third-party project is official P2F software.
• Sell or sublicense P2F Enterprise modules without an active commercial agreement.
