Corteza
Pros
- Released under the Apache 2.0 licence, so it can be self-hosted with no licence fees and no vendor lock-in.
- The project says its data model supports most Salesforce standard objects, and users can add their own custom objects.

Cons
- The CRM and Service Solution apps were removed from the default deployment in release 2024.9, so the CRM has to be built or installed separately.
- Reviewers say the interface is complex and can be overwhelming.
