Licence

Seaworthy is source-available. Two licences apply.

The scanner: Functional Source License

Everything except the paid features is licensed under the Functional Source License, version 1.1, with an Apache 2.0 future licence (FSL-1.1-ALv2). In plain terms:

  • You can use it free of charge for any purpose except offering a competing product or service, including at work, on client projects and in CI.
  • You can read, copy and change the code under the same terms.
  • Each release also becomes available under the Apache License 2.0 two years after it is published.

The full text ships with Seaworthy in its LICENSE file.

The paid features: Seaworthy Commercial Licence

The Pro and Agency features need a valid licence key and are covered by the licence below, which also ships with Seaworthy as LICENSE-COMMERCIAL.md.

Copyright 2026 Dynamo Maritime Ltd, registered in England and Wales, company number 17152743 ("we", "us").

1. What this licence covers

"Paid Features" means the source code in the src/pro/ folder of Seaworthy, and that code in any compiled or bundled form, including the parts of dist/ built from it. The rest of Seaworthy is licensed separately under the Functional Source License (see LICENSE).

"Licence Key" means a key issued by us, or by a reseller acting for us, when you buy a Seaworthy plan (for example Pro or Agency). "Plan" means the plan the Licence Key was issued for, together with its limits, such as the number of machines.

2. What you may do with a Licence Key

While you hold a valid, active Licence Key, we grant you a non-exclusive, non-transferable right to use the Paid Features that your Plan includes:

  • on no more machines than your Plan allows; and
  • for your own work, including producing reports for your own clients.

3. What you may do without a Licence Key

You may install, copy and redistribute the unmodified Seaworthy package that contains the Paid Features, for example through npm, package mirrors or caches. You may also read the source code. You may not use the Paid Features without a Licence Key.

4. What you may not do

You may not:

  1. remove, disable, modify or get around the licence check, the entitlement code or any limit of your Plan, or use a modified copy of Seaworthy to reach Paid Features your Plan does not include;
  2. share a Licence Key beyond your Plan's limits, or sell, rent or transfer it;
  3. modify the Paid Features or create derivative works of them;
  4. sublicense, sell or redistribute the Paid Features apart from the unmodified Seaworthy package; or
  5. use the Paid Features, or their source code, to build or provide a product or service that competes with Seaworthy.

Nothing in this licence limits any right you have by law that cannot be excluded by contract.

5. Your output

Reports, history files and other output you produce with the Paid Features belong to you. We claim no rights in them, and we never receive your code.

6. When the licence ends

Your rights under this licence end when your Licence Key expires or is revoked, for example when your subscription ends, or if you break this licence. You must then stop using the Paid Features. Output you have already produced stays yours, and the rest of Seaworthy keeps working under its own licence.

7. No warranty, and limits on liability

The Paid Features are provided "as is". They produce automated scan results. They are not a security certification or a guarantee, and no tool finds every problem.

As far as the law allows, we are not liable for any indirect or consequential loss, or for any loss of profits, revenue, data or goodwill. Our total liability to you under or in connection with this licence is limited to the amount you paid for your Licence Key in the 12 months before the claim.

Nothing in this licence limits or excludes liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be limited or excluded by law. If you are a consumer, your statutory rights are not affected.

8. Purchase terms

Prices, billing, renewals and refunds are covered by the terms you accept at checkout, not by this licence.

9. Law

This licence is governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
