Our pick · odoo
Our pick is Odoo for a small business that wants more than a CRM: Odoo Community is open source under LGPL-3.0, and its CRM sits alongside apps such as sales and invoicing. SuiteCRM is the better fit if you only need a CRM: it is a dedicated CRM licensed AGPL-3.0. Odoo Enterprise, the licensed edition, is built on top of Community.
★ 55,306 starsLicence: LGPL-3.0Last commit 25 Oct 2026Python
A comprehensive open-source business management suite which includes a robust CRM module for managing leads, opportunities, and customer relationships.
Best for: Small businesses that anticipate needing a broader, integrated business management solution beyond just CRM, willing to invest significant technical resources for setup, customization, and ongoing management.
What's good
Seamlessly integrates the CRM module with other Odoo applications like accounting, inventory, and project management if a full ERP is desired later.
Features a modern, clean, and highly customizable interface with excellent visual reporting and dashboards.
Offers strong lead and opportunity management, sales pipeline visualization, and automation features suitable for growing businesses.
Backed by a large company and an extensive global community, ensuring continuous development, updates, and module availability.
Watch out for
Can be very resource-intensive and complex to deploy and maintain, often requiring Docker or specialized hosting and technical expertise.
The open-source Community Edition lacks several advanced features, integrations, and performance optimizations present in the paid Enterprise Edition.
Can be overwhelming and overkill if a business only needs a simple CRM and isn't looking for a broader, integrated ERP solution.
The modularity can lead to a steeper initial learning curve as users navigate multiple interconnected applications.
A powerful and highly customizable open-source CRM suite offering extensive sales, marketing, and customer service automation.
Best for: Small to medium businesses needing a highly customizable and feature-rich CRM that have dedicated technical resources for setup, maintenance, and ongoing development.
What's good
Offers a comprehensive suite of features rivaling many commercial CRMs, covering sales, marketing, and support.
Highly customizable to adapt to specific business workflows, data models, and reporting needs.
Benefits from a large, established community and ecosystem providing ample resources and third-party integrations.
Self-hostable, providing complete control over data and infrastructure without vendor lock-in.
Watch out for
The user interface feels dated and can be less intuitive compared to modern CRM applications, impacting user adoption.
Can be complex to set up, configure, and maintain, often requiring significant technical expertise or IT resources.
Performance can be an issue on lower-spec servers or with large datasets, requiring careful optimization.
Upgrades can be challenging and sometimes lead to unexpected issues, particularly with custom modifications.
"Dormant" means no commit pushed to the default branch in the last 12 months. "Archived" means the maintainers have marked the repository read-only on GitHub. "Deprecated" means the project's README says it is deprecated or no longer maintained. Stars, licence, commit and release dates come from the GitHub API (GitLab for projects developed there) and are cached for up to 24 hours. The written analysis is AI-assisted and checked against that data.
CRM-only vs all-in-one
SuiteCRM is a dedicated open-source CRM. Odoo is a suite of business apps, including sales, CRM and invoicing, so its CRM is one app among many that share the same system.
Odoo comes in two editions: Odoo Community, which is open source, and Odoo Enterprise, which is licensed. Community is the core that Enterprise is built on, and Odoo says you can switch between them at any time.
Odoo needs Python 3.10 or later and a PostgreSQL database. SuiteCRM 8 needs PHP 8.2 or later, Apache 2.4, and MySQL or MariaDB. Both also have hosted options: Odoo Online, and a hosted SuiteCRM trial.
Odoo and SuiteCRM are active: each has had a commit in the last 12 months (most recent: Odoo on 25 Oct 2026, SuiteCRM on 23 Oct 2026). Status is checked against GitHub daily.
What licences do Odoo and SuiteCRM use?
Odoo: LGPL-3.0; SuiteCRM: AGPL-3.0. Check each project's licence file before use.
