Open-source alternatives to Zoho CRM

Comparison notes

Twenty (twentyhq) is a modern developer-first CRM with a clean data model and GraphQL API, still maturing in automation rule depth and reporting analytics compared to Zoho's deep workflow builder. SuiteCRM is a full-featured open-source CRM forked from SugarCRM, covering Zoho's sales, marketing, and reporting functionality most completely, but its PHP codebase and dated UI require significant configuration work for modern sales team workflows. Zoho's native AI features and deep integration with the broader Zoho ecosystem — Books, Desk, Campaigns — have no direct equivalent in either open-source option.

Migration tips

• Export Zoho CRM contacts, leads, and deals as CSVs from each module separately and import into SuiteCRM or Twenty using their respective importers, with manual field mapping review for each object type.
• Recreate your most critical Zoho workflow automation rules in SuiteCRM's workflow module first before migrating the full dataset — validate that key automation triggers work correctly before going live.
• Twenty's GraphQL API allows importing data programmatically for teams with development resources, which may be faster than CSV import for large contact databases.

FAQ

Can I fully replace Zoho CRM with an OSS tool?

Feature parity varies. Most OSS alternatives cover 70-90% of core workflows, but may lack polish, integrations, or specialized features. Pilot the alternative with a subset of your team before fully committing.

What's the cost of self-hosting?

Plan for ~$5-50/month in VPS costs (DigitalOcean, Hetzner, etc.) plus 2-8 hours/month in maintenance. For a team of 20+, self-hosting usually breaks even against SaaS pricing within 6-12 months.

Which alternative should I pick?

Sort by GitHub stars (a proxy for community health), check the last-pushed date (avoid unmaintained projects), and read recent issues to gauge responsiveness.
