Open Source CRM Alternatives Compared: Replace Salesforce and HubSpot
Why Switch to an Open Source CRM?
Salesforce costs $25-$300 per user per month. HubSpot's CRM is "free" until you need marketing features — then it's $800+/month. For growing teams, CRM costs become one of the largest SaaS line items.
Open source CRMs offer the same core functionality — contact management, deal pipelines, email integration, and reporting — without per-seat pricing. Let's compare the best options.
Top Open Source CRMs
Twenty
The modern CRM. Twenty is the newest contender, built from the ground up as a modern, open source alternative to Salesforce. Clean UI, fast, and developer-friendly.
- License: AGPL-3.0
- Tech stack: TypeScript, React, NestJS, PostgreSQL
- Key features: Custom objects, pipeline views, email sync, API-first design
- GitHub stars: 20K+
- Self-hosting: Docker Compose
- Managed option: Twenty Cloud (beta)
Standout: The API-first architecture means you can build custom integrations without hacking around the UI. The data model is genuinely flexible — create custom objects without writing code.
Best for: Teams wanting a modern, extensible CRM they can shape to their workflow.
SuiteCRM
The Salesforce veteran. SuiteCRM has been the go-to open source CRM since SugarCRM went proprietary. It's mature, feature-complete, and battle-tested in enterprise environments.

EspoCRM
Lightweight and flexible. EspoCRM is an elegant CRM that punches above its weight. Clean interface, fast performance, and surprisingly deep customization.

ERPNext (CRM Module)

Migration Guide
From Salesforce
- Export your data — Salesforce Data Loader or Dataloader.io
- Map your objects — Accounts → Companies, Opportunities → Deals
- Choose SuiteCRM or Twenty — SuiteCRM for feature parity, Twenty for modern UX
- Import via CSV — All OSS CRMs support CSV import
- Rebuild automations — This is the most time-consuming step. Document your Salesforce flows first.
From HubSpot
- Export contacts, companies, and deals — HubSpot export tool
- Choose Twenty or EspoCRM — Both match HubSpot's clean UX philosophy
- Set up email integration — Connect your email provider for tracking
- Migrate email templates — Manual process, but worth it
Self-Hosting Considerations
- Database: All options use PostgreSQL or MySQL. Use managed databases (AWS RDS, DigitalOcean) for reliability.
- Email: CRM email sync requires IMAP access. Ensure your email provider allows it.
- Storage: File attachments add up. Plan for 10-50GB+ over time.
- Backups: Daily database backups are non-negotiable. Test restoration regularly.
