We're working on open source CRM project. Maybe it will be interesting to someone.
Client part has done with #vuejs, #vuetify, #vuex and API created with #symfony and #api-platform
It can be used as a standalone product, or as a core for new projects.
CRM has a lot of functionality, like JWT authorization, user management and roles restrictions and many others.
We'll be happy to answer any questions and discuss new functionality.
