Attio alternative
Attio is a well-regarded closed-source SaaS CRM with strong data-model flexibility. There is no self-hosting option, though, and its AI is a proprietary, Cloud-only feature. If you want to own your data and self-host the same AI and MCP tooling your team uses in production, Spaceport is the alternative.
