2 Best Open Source HubSpot Alternatives

Why choose an open-source HubSpot alternative

HubSpot bundles marketing automation, CRM, and support tools behind pricing that rises with contact count and add-on modules, so a growing contact list can push a team into a more expensive tier without adding a single new feature. Self-hosted alternatives put that infrastructure under your own control:

• Data ownership: customer and contact data stays on infrastructure you control instead of syncing into a vendor's marketing cloud, which matters for teams with strict data-handling policies.
• Self-hosting: keep CRM and marketing data in-house for compliance reasons, particularly in industries where contact data is subject to regulation.
• Cost: self-hosted tools avoid the per-contact billing that makes HubSpot pricing climb as your list grows, whether those contacts are active customers or old leads.
• Customization: modify pipelines, campaign logic, and integrations at the code level instead of working within a fixed set of marketing automation rules.
• Avoiding lock-in: your contact database and campaign history stay portable rather than tied to one vendor's export format and API limits.

What to look for

Compare the depth of marketing automation available, such as email campaigns, lead scoring, and segmentation, whether a sales CRM pipeline is included alongside the marketing tools, which channels are covered including email, SMS, chat, and social, the stack the tool runs on since that affects hosting complexity and maintenance, and how much built-in reporting is available without needing a separate analytics tool.

How the top HubSpot alternatives compare

• Mautic is a PHP-based marketing automation platform focused on email campaigns, lead scoring, and segmentation, closest to HubSpot's original marketing-hub roots before it expanded into a full suite.
• Erxes is a broader "experience operating system" that combines marketing, sales CRM, and a support desk in one stack, aiming to replace HubSpot, Zendesk, and Linear together for teams that want one system instead of three.

Mautic has a longer track record as a standalone project and a wider library of third-party integrations built up over its history; Erxes is younger but covers more ground in a single deployment, which reduces the number of separate tools a small team needs to maintain.
