Pricing
Source available — free under the Evaluation License, or licensed commercially for production.
License Model
Three things to know before going further.
Source available
All DevKit repositories are public on GitHub. Read, study, file issues, and contribute via pull requests.
Evaluation License — free
Use the DevKit free of charge for evaluation, learning, and training. Unlimited duration, non-commercial only, no support.
Commercial License — by agreement
Production deployment and integration into proprietary projects require a signed Commercial License agreement with Digital Substrate.
License Comparison
Two modes of use — pick the one that matches your project.
Evaluation License
Free
Unlimited duration. Non-commercial.
Permitted
- Evaluating fit for your workflow
- Training and learning
- Sharing results with a limited number of third parties — free of charge, no commercial benefit
- Filing issues and contributing pull requests
Not included
- Any commercial use, direct or indirect
- Use in negotiations, tenders, or commercial transactions
- Modification (use only as distributed)
- Redistribution or sublicensing
- Support, maintenance, or updates
Commercial License
By agreement
Tailored to your deployment. Signed agreement required.
Permitted
- Production deployment
- Integration into proprietary projects and products
- Modification, redistribution, sublicensing — as defined in the Agreement
- Support and maintenance — per Agreement
- Updates within the LTS-1.2 line
How it works
- Granted only via a signed agreement with Digital Substrate.
- Scope (seats, deployments, support level) is set in the Agreement.
- Conversion from Evaluation is straightforward — no reinstall.

Contributing
We welcome contributions across all DevKit repositories. Each repo includes a
CONTRIBUTING.md with instructions. By submitting a contribution, you agree
that your contribution will be licensed under the same Digital Substrate Commercial
License as the receiving repository.
Third-party components
The DevKit links the Qt framework dynamically under LGPL v3. Qt is provided as a separate, replaceable component; replacement instructions and the source code of the exact version used are documented in each repository.
Frequently asked questions
What counts as "commercial use" under this license?
Commercial use is defined broadly in the license — it includes any direct or indirect commercial benefit, including use in negotiations, tenders, or commercial transactions. If your intended use is not pure evaluation or training, contact us so we can confirm whether a Commercial License is required.
Can my company evaluate DevKit internally before signing a Commercial License?
The Evaluation License explicitly covers assessment for fit with your workflow and training. Internal evaluation in that scope is permitted. The boundary between "evaluation" and "internal commercial use" is one we are happy to discuss case by case — please reach out.
I'd like to fix a bug or contribute a feature — what's the process?
Open an issue or a pull request on the relevant repository under
github.com/digital-substrate.
See the CONTRIBUTING.md in each repo for instructions. Modification of
the source for your own use — rather than contributed back — requires a Commercial
License.
How do I get a Commercial License quote?
Contact us with a short description of your project — team size, deployment scope, timeline. We tailor the agreement to your situation.
What about Qt licensing?
Qt is provided dynamically linked under LGPL v3. The DevKit imposes no technical measures preventing replacement. The exact source version and replacement instructions are documented in each repository alongside the license.
