Licensing
Overview
NAT uses a dual licensing model:
| License | For whom |
|---|---|
| AGPL-3.0 (open source) | Open source projects, individual developers, internal use |
| Commercial license | Companies that want to use NAT in proprietary software or SaaS products without AGPL copyleft requirements |
Open Source License: AGPL-3.0
NAT is free and open source software licensed under the GNU Affero General Public License v3.0 (AGPL-3.0).
Under the AGPL-3.0, you are free to:
- Use NAT for any purpose
- Modify NAT
- Distribute NAT
- Use NAT to scan your own applications and services
AGPL copyleft requirements: If you distribute NAT or run a modified version of NAT as a network service (e.g., a SaaS product that wraps NAT), you must make the complete corresponding source code available under the AGPL-3.0.
The full text of the AGPL-3.0 is available at gnu.org/licenses/agpl-3.0 (opens in a new tab).
Commercial License
A commercial license is available for organizations that:
- Want to use NAT as part of a proprietary software product or SaaS offering
- Need to keep modifications or integrations private
- Want enterprise support, SLAs, and indemnification
- Prefer not to be bound by the AGPL-3.0 copyleft requirements
Commercial license customers receive:
- A perpetual license for the agreed version(s)
- Permission to use NAT in proprietary products
- Access to the Enterprise plan features
- Priority support with defined SLAs
- Indemnification coverage
To inquire about a commercial license, contact hello@nat-testing.io.
SaaS Plan Terms
If you use NAT through the hosted SaaS service (app.nat-testing.io), your use is governed by the Terms of Service (opens in a new tab) and Privacy Policy (opens in a new tab), not the AGPL-3.0.
Third-Party Licenses
NAT incorporates third-party open source components. A complete list of third-party licenses is included in the THIRD_PARTY_LICENSES file distributed with the software.
Questions
If you have questions about which license applies to your use case, contact hello@nat-testing.io.
TL;DR for most users: If you're using NAT to scan your own APIs — whether as a developer, as part of your company's security program, or in CI/CD — you can use it freely under the AGPL-3.0. The commercial license is only relevant if you're building a product that includes or wraps NAT.
