Open-Source HubSpot Alternatives: CRMs You Can Self-Host and Own
HubSpot's free CRM is generous, but it is still HubSpot's software on HubSpot's servers, and the jump to paid seats, credits for its Breeze AI and marketing tools adds up as a startup grows. Open-source CRMs let you run the same core jobs, contacts, companies, deals and pipelines, on your own server, with no seat licences and full access to your data and code. The 2025 version of this article listed some projects that are now archived or unmaintained; we checked every licence, latest release and AI claim below on GitHub and the official sites on 12 November 2026.
Quick answer: for a modern, HubSpot-like sales CRM, choose Twenty (AGPL-3.0) or EspoCRM (AGPL-3.0). For a full suite close to Salesforce, SuiteCRM. If you also need invoicing, stock or accounting, Odoo Community or Dolibarr. Non-profits should look at CiviCRM, and Mautic replaces HubSpot's marketing automation side.

What HubSpot Offers in 2027
On HubSpot's CRM pricing page (default view, US dollars, checked November 2026) the free CRM costs $0 for up to 2 users and 1,000 contacts, with no time limit. Starter starts at $7 per seat a month for new customers; the FAQ explains that this is with an upfront annual payment, $10 month-to-month, and that Starter is normally $20 per seat a month. Starter includes 500 HubSpot Credits and help from Breeze Assistant, HubSpot's AI. Open-source CRMs remove the seat price, but you pay for hosting and do the updates yourself.

The 10 Best Open-Source HubSpot Alternatives in 2027
1. Twenty: the modern open-source CRM
Twenty is the closest open-source match to HubSpot's clean, record-based CRM: companies, people, opportunities and tasks in customisable tables, plus workflows and an API. Its site describes it as building blocks for a custom CRM for technical teams. The code is AGPL-3.0, except files marked Enterprise (commercial licence) and a few MIT packages. On Twenty's pricing page self-hosting the open-source core is free, and the Cloud plans cost $9 (Pro) and $39 (Organization) per user a month on yearly billing, with AI that handles CRM chores and monthly credits for workflows, AI agents and apps. Version 2.57.1 came out on 9 November 2026.
2. EspoCRM: a light, flexible CRM with optional AI
EspoCRM (AGPL-3.0) is free open-source CRM software for contacts, sales, support and marketing in one place, with workflows, automation and an open API. It runs on an ordinary PHP host, and there is also a hosted cloud version. For AI, the official Intelligence add-on connects EspoCRM to OpenAI, Gemini, Claude or any OpenAI-compatible model and adds record summaries, intelligent paste, an AI email composer and AI formula functions for classification and data extraction, with usage logging and quotas. Version 10.1.1 came out on 10 November 2026.
3. SuiteCRM: a full CRM suite with no licence fees
SuiteCRM (AGPL-3.0) is a long-running open-source CRM covering sales, marketing campaigns and customer service. Its site promises no licence fees and no vendor lock-in, and you can self-host it or buy managed hosting. It is a heavier system than Twenty or EspoCRM, so it suits a startup that expects to need complex modules, roles and reports. The latest SuiteCRM 8 release, 8.10.2, dates from July 2026, and its official pages do not describe built-in AI features.
4. Odoo Community: CRM inside an open-source ERP
Odoo is a suite of business apps; the Community edition on GitHub is LGPL-3.0 and includes the CRM app with its sales pipeline, next to invoicing, inventory, e-commerce and more. The cloud versions are not all open source: on Odoo's pricing page (default view, euros) One App Free costs €0 for one app with unlimited users on Odoo Online, and "Agentic AI" is listed only in the paid Custom plan. Choose Odoo if you want CRM, quotes and invoices in one system and can host it yourself or pay for hosting.
5. Krayin: a simple Laravel CRM
Krayin is a free, MIT-licensed, self-hosted CRM built on Laravel (PHP) and Vue.js for leads, customers and sales pipelines, and it is easy for a PHP developer to extend. Its configuration includes a Magic AI section that connects AI models through your own OpenRouter key. The company also sells managed hosting; its site advertised $20 a month for unlimited users when we checked. Version 2.2.8 came out on 6 November 2026.

6. Dolibarr: CRM plus quotes, invoices and stock
Dolibarr (GPL-3.0) is a web-based open-source ERP and CRM for freelancers, small businesses and foundations: contacts, commercial proposals, orders, invoices, products, stock, emailings and more, each switched on as a module. It is a good fit if your "CRM" really means quotes and invoices for a small client list. Version 24.0.3 came out on 11 November 2026.
7. Corteza: a low-code platform with a CRM
Corteza presents itself as an open-source low-code platform and Salesforce alternative, released under the Apache-2.0 licence. It ships a CRM and case management, and you can build your own data models, workflows and integrations on top. It suits a technical founder who wants to shape the CRM around an unusual process. Release 2026.9.0 came out in October 2026.
8. Axelor: CRM inside an open-source ERP
Axelor is an open-source ERP whose CRM sits in the same database as sales, projects and accounting, so a deal can flow into an order and an invoice. Axelor Open Suite is AGPL-3.0 on GitHub, and version 9.1.11 came out in October 2026. It is a bigger system to install (Java), so it suits a growing company more than a two-person team.
9. CiviCRM: for non-profits and social enterprises
CiviCRM (AGPL-3.0) is open-source constituent relationship management for non-profits, NGOs and advocacy groups: donors, members, events and communications. It runs inside your website on WordPress, Drupal, Joomla or Backdrop, and CiviCRM 6.20 was released on 8 November 2026. If your startup is a charity or a foundation, it fits far better than a sales CRM.
10. Mautic: open-source marketing automation
Mautic (GPL-3.0) replaces the Marketing Hub side of HubSpot: email marketing, lead management, segments and automated campaigns, with email, SMS and WhatsApp shown on its homepage and unlimited contacts. Pair it with one of the CRMs above if you need both sales and marketing. Version 7.2.2 came out on 26 October 2026; our open-source Mailchimp alternatives guide covers more email tools.
How to Move From HubSpot to an Open-Source CRM
Open source moves the cost from licences to your own time. Before you switch, decide who will host, update and back up the CRM, and test the move on a copy first.
HubSpot Alternatives That Changed or Are Not Open Source
- YetiForce: its main GitHub repository is archived; the README points to a new repository, which had only a handful of commits and no release when we checked.
- X2CRM: its last release, 7.1, dates from October 2019 and the repository has had no commits since December 2022.
- Erxes: its licence is AGPL-3.0 plus an extra rule that it may not be hosted as a SaaS competing with Erxes Inc., and enterprise plugins are under a separate licence, so it is not plain OSI open source.
- Vtiger: we could not confirm the current open-source edition on an official page (the sites refused our checks), so it is not in the list.
- OroCRM: still maintained under OSL-3.0 (tag 7.0.4, August 2026), but it is aimed at B2B commerce with OroCommerce rather than a startup sales team.
Which Open-Source HubSpot Alternative Should You Choose?
- You liked HubSpot's free CRM and want the closest feel: Twenty.
- You want a light CRM on cheap PHP hosting, with AI if needed: EspoCRM.
- You need a full enterprise-style CRM: SuiteCRM.
- You also need quotes, invoices and stock: Dolibarr (small) or Odoo Community (larger).
- You are a non-profit: CiviCRM.
- You mainly used HubSpot for email marketing: Mautic, plus a CRM above.
