Best Open-Source HubSpot Alternatives (2026)

10 self-hostable, open-source projects that replace HubSpot — without costs that balloon as contacts grow. Each is scored for how hard it is to self-host, with one-click deploy options where they exist.

HubSpot's free tier is generous, but the bill climbs fast once your contact count grows and you need Marketing or Sales Hub features that are gated behind per-seat tiers. Teams also chafe at owning their customer data inside a closed SaaS that's hard to export from cleanly.

Our picks at a glance

Easiest to self-host
EspoCRM

At difficulty 3/5 it's the lowest-friction self-host here, a lightweight PHP app with Docker support and managed hosting available.

Most powerful
Odoo (CRM)

Its CRM is one app inside a full ERP suite, so you get sales, marketing, invoicing and inventory under one roof — the closest match to HubSpot's all-in-one ambition.

Most active
Odoo (CRM)

At ~52,400 stars it has by far the most momentum of any option on this list.

Best managed option
Odoo (CRM)

Odoo offers a mature official cloud (Odoo Online/SaaS) alongside self-hosting, the most established managed option of the group.

What to look for: Decide whether you need a focused CRM or a full marketing/sales suite, because that splits this list sharply. If marketing automation and email campaigns are the real reason you're paying HubSpot, weigh Mautic for that piece separately; for the CRM core, prioritize a flexible data model and a credible migration path off HubSpot's exports.

The verdict

For a true HubSpot-style all-in-one, Odoo is the strongest pick thanks to its ERP breadth, huge community, and official cloud; if you only want a clean CRM core, EspoCRM is the easiest to stand up and run.

HubSpot alternatives — frequently asked questions

Is there a free open-source HubSpot alternative?

Yes — all ten options here are free and open-source. Odoo (LGPL-3.0), EspoCRM, Frappe CRM and SuiteCRM (AGPL-3.0), Krayin and OroCRM (MIT), and Dolibarr, Mautic and CiviCRM are all freely self-hostable with no per-contact fees.

Which HubSpot alternative is easiest to self-host?

EspoCRM at difficulty 3/5 is the lightest to deploy via Docker. Frappe CRM is also 3/5; the rest (Odoo, Krayin, Mautic, Dolibarr, SuiteCRM, CiviCRM) sit at 4/5, and erxes and OroCRM are the hardest at 5/5.

Which one replaces HubSpot's marketing automation, not just the CRM?

Mautic is purpose-built for marketing automation and email campaigns at scale. For an all-in-one that bundles marketing with CRM and sales, Odoo or erxes (which unifies sales, marketing and support) fit better.

Can I get managed hosting instead of running it myself?

Yes for several: Odoo, Dolibarr, SuiteCRM, erxes, EspoCRM, Frappe CRM and OroCRM all offer managed hosting. Krayin, Mautic and CiviCRM are self-host only.

What's the best HubSpot alternative for nonprofits?

CiviCRM is built specifically for nonprofit constituent relationship management — membership, donations and contacts — though it's manual-deploy only and rates difficulty 4/5.

Which has the most active community?

Odoo leads at roughly 52,400 GitHub stars, well ahead of Krayin (~23,000) and Mautic (~9,800).
