Free and open-source Salesforce alternative: Corteza

If anyone is looking for a real free and open-source Salesforce alternative, I recommend checking out Corteza Project. It's 100% free, and you can self-host it. It comes with CRM, Service Cloud, and Messaging (this last one as a Slack alternative).

You can try it out online at https://latest.cortezaproject.org/ or get more info (features, how to download and install,…) at https://cortezaproject.org/.
