Alighieri is dual-licensed:
- Open source — the default. Unless you have signed a commercial agreement
with WireSock, Alighieri is provided to you under the GNU Affero General
Public License, version 3.0 or later (
AGPL-3.0-or-later) — the terms inLICENSE— and your use must comply with it. - Commercial — by agreement. A commercial license from WireSock is available as an alternative to the AGPL; it applies only if and once you have signed a commercial agreement (see Contact).
The AGPL is a strong copyleft license. In particular, its section 13 (remote network interaction) requires that if you run a modified version of Alighieri as a network-accessible service, you must offer that service's users the complete corresponding source code of your modified version under the AGPL.
The AGPL is a good fit if you:
- run Alighieri unmodified, or
- are willing to release your modifications under the AGPL.
You likely want a commercial license if you:
- embed or redistribute Alighieri inside a proprietary product without releasing your source under the AGPL,
- run a modified Alighieri as a hosted / SaaS service and do not want to publish your modifications, or
- need assurances the AGPL does not provide (e.g. warranty, indemnification, or support).
The commercial license grants the same software under terms that remove the AGPL's copyleft and source-disclosure obligations. Commercial terms are agreed separately — contact us for details.

- This document is a plain-language summary of the licensing options. It is not
legal advice and does not modify the AGPL terms in
LICENSE; where this summary and the AGPL differ, the AGPL governs open-source use. - Third-party dependencies remain under their own licenses.
- Contributions: so that the project can be offered under both licenses, by submitting a contribution you license it under the AGPL-3.0-or-later and additionally grant WireSock the right to redistribute your contribution under a separate commercial license.
