I built IceburgCRM (available in Django or Laravel). You can create a specialized crm with only a few words. For example: "create a stamp collecting crm". Modules, Fields, Relationships, Subpanels, default data and even a image for your homepage is created.
Data can be imported/exported into 6 different formats. Supports unlimited many to many relationships, 26 different themes, etc.
This is what the default crm looks like: https://demo.iceburg.ca/
Here are some samples I generated:
Gourmet Coffee Enthusiasts CRM
Bee Keeping CRM https://beekeeping.iceburg.ca
You can also manage an existing database as a CRM.
Here is a default wordpress database crm.
