License
Free core, paid extras
AGPL-3.0 · Open source (copyleft)
What you need to do
The core is free to use. Enterprise features, kept in a separately licensed part of the code, need a paid license in production.
For Rallly
The code is AGPL-3.0, but the official self-hosted build allows one user without a license key; Plus (5 users), Organization (50) and Enterprise keys are paid. The AGPL lets you change that, but the vendor’s builds and updates assume a key.
AGPL-3.0 (self-hosted builds need a paid license key past one user) · Open source (copyleft). OSI-approved license that requires sharing changes under the same license when you distribute (AGPL: also when you offer it over a network).
