Licenses¶
Didacta is fair-code, source-available, aligned with the faircode.io movement. It is not open source under the OSI definition.
What you can do¶
- ✅ View, read, copy, modify and distribute the code.
- ✅ Run Didacta in production for your organisation's internal purposes (training your employees, an internal LMS…), at no cost and with no per-user licensing.
- ✅ Non-commercial or personal use: research, learning, evaluation, contribution.
- ✅ Distribute the software or your modifications free of charge, for non-commercial purposes.
- ✅ Proofs of concept, evaluations, audits and demos.
What requires a commercial agreement¶
- ❌ Distributing Didacta or derivatives for a fee.
- ❌ Offering Didacta as paid SaaS or managed hosting for third parties.
- ❌ Selling Didacta white-labelled or rebranded for resale.
- ❌ Sublicensing Didacta as part of a commercial product.
- ❌ Removing or altering copyright, license or trademark notices.
- ❌ Using the Didacta trademarks beyond what applicable law permits.
For any of these cases: licensing@didacta.io, or use Didacta Cloud (cloud.didacta.io).
Two licenses, one repository¶
| Code | License |
|---|---|
Everything that is not *.ee.* and not inside ee/ folders |
Didacta Sustainable Use License v1.0 — the fair-code sustainable use license |
*.ee.* files, or files inside ee/ folders (in the core only) |
Didacta Enterprise License |
| Third-party components | Their original upstream license |
Files under the Enterprise License require a valid Enterprise license key to be used in production; without one, the License SDK gates them at runtime (see Enterprise). Modules are never under the Enterprise License: all of them are Community.
