3 Free & Open-Source HubSpot Alternatives
HubSpot's free CRM tier covers the basics, but contact limits, locked-away automation, and per-seat pricing on the paid tiers add up quickly for a growing sales team. Self-hosted CRMs remove the seat tax entirely — the trade-off is you (or your dev team) own the setup and updates.
The best HubSpot alternatives
Twenty
Our top pickOpen sourceSelf-hostedA modern, Notion-like CRM built from scratch.
Twenty is a newer open-source CRM designed around a clean, spreadsheet-and-kanban interface rather than the dense, form-heavy UI most CRMs inherited from the 2000s. It's the most approachable option here for a small team that wants something that doesn't feel like enterprise software.
- Customizable objects and fields, similar to Airtable/Notion
- Kanban pipeline views alongside table views
- API-first architecture for custom integrations
- Self-hosted or a managed cloud option
EspoCRM
Open sourceSelf-hostedA mature, straightforward sales and support CRM.
EspoCRM has been around long enough to be genuinely stable, covering the sales-pipeline and email-integration basics most small businesses actually need without HubSpot's marketing-suite bloat.
- Sales pipeline (kanban) with custom stages
- Email integration (IMAP/SMTP two-way sync)
- Workflow automation for follow-ups and assignment
- Role-based permissions for teams
SuiteCRM
Open sourceSelf-hostedAn enterprise-grade CRM with a deep module system.
SuiteCRM (a long-running fork of SugarCRM's open-source line) is the most feature-dense option here — built for businesses that expect to heavily customize their CRM's data model and workflows rather than use it out of the box.
- Highly customizable modules and layouts
- Advanced workflow and process-automation builder
- Built-in reporting and dashboards
- Large community of implementation partners
Licensing and pricing models change over time — confirm current terms on each project's own site before making a procurement or compliance decision.
Frequently asked questions
What's the best free HubSpot alternative for a small business?
Twenty is the easiest starting point if your team wants something simple and modern. If you need deeper customization of fields and workflows from day one, EspoCRM or SuiteCRM give you more to work with, at the cost of a steeper setup.
Will I lose HubSpot's marketing automation by switching?
Mostly, yes — these are CRMs first. If email nurture and lead scoring matter as much as the pipeline itself, pair one of these with Mautic (see our Mailchimp alternatives) rather than expecting a single free tool to replace HubSpot's whole suite.
Is self-hosting a CRM safe for customer data?
It can be more secure, since the data never leaves infrastructure you control — but that security is only as good as your own setup: backups, access controls, and patching become your responsibility instead of the vendor's.
