Which CRM fits your situation?
Honest cost math (self-hosting)
- Software: $0 (open-source license)
- Server: $5-$50/mo VPS (DigitalOcean, Hetzner, Linode)
- Backups: $5-$15/mo backup service
- SSL + domain: $15-$30/yr
- Initial setup: 8-40 hours (depending on customization needs), or $500-$5,000 paid implementation help
- Ongoing ops: 1-3 hours/month maintenance, security updates, troubleshooting
Real all-in for a 5-person team: ~$15-$80/mo recurring + the initial setup time. Compare to SaaS at $50-$300/mo for 5-person teams.
When NOT to pick open-source
- No technical operations capacity on your team
- HubSpot Free or Zoho CRM Free covers your needs (truly free + hosted)
- You'll spend more time on the CRM ops than the CRM saves you
- You need vendor-grade support SLAs

Frequently asked
What's the best open-source CRM?
SuiteCRM is the most-deployed open-source CRM globally: fork of the original SugarCRM Community Edition, still actively maintained. EspoCRM is a strong alternative with a cleaner modern UI. Odoo Community Edition bundles CRM with ERP modules: overkill for pure CRM, ideal if you also need accounting/inventory.
Is open-source CRM actually free?
The software is free (open-source license). Self-hosting costs include: server (~$5-$50/mo VPS or own hardware), backups, security updates, occasional troubleshooting time. For a technically-resourced small business, total real cost is $10-$100/mo. For non-technical teams, factor in implementation help ($500-$5,000 one-time).
Should I pick open-source over HubSpot Free?
Usually no, unless you have a specific reason. HubSpot Free is genuinely free, hosted, professionally maintained, no operational burden. Open-source wins when: (1) you need data sovereignty (compliance reasons), (2) you need deep customization beyond what SaaS allows, (3) you have technical operations capacity, or (4) you're scaling past where SaaS pricing makes sense.
Which open-source CRM has the best community?
SuiteCRM has the largest active community by deployment count. EspoCRM has very active GitHub development with frequent releases. Odoo has massive community plus commercial support. Vtiger has active community plus paid cloud option for those who want hosted.
