loop is free software under the GNU Affero General Public License, version 3 or later (AGPL-3.0-or-later). For most open-source and personal use, the AGPL is all you need, and it costs nothing.
This page is for the case where the AGPL's terms don't fit.
The AGPL is strong copyleft with a network clause. If you modify loop and run it to provide a service over a network (a hosted remembrance or interview service, say), the AGPL requires you to offer the complete corresponding source of your modified version to that service's users. Redistributing loop as part of a larger work carries the same obligation. A commercial license may fit if you want to:
- Embed loop in a closed-source product you distribute, without releasing your own source under the AGPL.
- Run a modified loop as a hosted network service without the AGPL's requirement to publish your modifications to users.
If you're using stock loop yourself, building open-source software, or contributing back, you almost certainly do not need a commercial license.
A commercial license grants relief from the AGPL's copyleft and network-disclosure obligations for the agreed scope. It does not by itself include a warranty, support, indemnity, or an SLA — those can be negotiated separately but are not implied. loop's technical claim is unchanged by any license: tamper-evidence on one machine, never tamper-proof. A commercial license changes your licensing obligations, not what the software guarantees.
Note — loop runs on Rusty, which is itself AGPL-3.0-or-later and dual-licensed by the same author. A commercial deployment that embeds Rusty can be licensed together — mention your setup in the inquiry and we'll cover both.
Contact Nicholas Vermeulen at thelakeman@protonmail.com with a short description of your intended use (what you're building, whether it's distributed or a network service, rough scale). Terms are negotiable.
