Zoho CRM is a cloud-based CRM aimed at small and mid-sized businesses, priced well below enterprise competitors like Salesforce. It's still a closed-source, subscription-priced product, though — every user seat adds to the monthly bill, and your customer data lives on Zoho's servers rather than your own infrastructure.
Twenty is the closest match if you want a modern, actively developed CRM with customizable objects and workflows similar to Zoho's flexibility. Krayin is a solid pick if you want a mature, self-hosted Laravel CRM for standard lead and pipeline management, while Atomic CRM is worth considering if you'd rather fork a lightweight React + Supabase codebase and customize it directly.
