Ask HN: CRM/ERP – Free Open Source

I started by asking AI/googling then went on to check. Stuff like odoo or espocrm is crippled opencore software where they actually rip out essential parts from the free offering in order to force monitization. So I couldn’t find any modern crm or erp that’s open source and isn’t crippled or looks/feels like the 90’s. I would love to hear what people actually use. Looking for free, open source, modern. Not opencore crippleware, not saas!
