HubSpot Free

Best for a free cloud CRM

Odoo CRM

Best for open source apps

Odoo's One App Free plan runs the CRM for unlimited users at no cost, and the source is open. The catch is famous: add a second Odoo app and the free ride ends. For a pure CRM need, it is remarkable value.

Bitrix24

Best for free unlimited users

Few free plans include unlimited users; Bitrix24 does, bundling CRM, tasks and chat. It is a lot of product, which means a busier interface and a learning curve in exchange for the generosity.

A genuinely open source CRM, AGPL licensed, that is light and pleasant to self host, with a paid cloud if you prefer. Free to run on your own server, though you own the upkeep.
