Pros & Cons
Atomic CRM
Pros
- Free under the MIT license with unlimited users and data, and commercial modification is allowed.
- The codebase is small (about 15k lines, per Marmelab), so developers can adapt the data model quickly.
- It supports SSO through Google, Azure, Keycloak, Auth0 and SAML 2.0, which Marmelab says is rare among open-source CRMs.
- Email to Note turns emails you CC to the CRM into notes.
- An MCP server lets AI assistants query and update CRM data under the same access rules as users.
Cons
- You need Docker, Node and Supabase/Postgres skills to set it up and run it.
- There are few built-in integrations, so connectors to tools like HubSpot or Salesforce need custom work.
- Support comes from the GitHub community, with no SLA unless you pay for Marmelab services.
- No compliance certifications such as SOC 2 or HIPAA are published.
- It has only basic features, with no marketing automation or advanced reporting.
Odoo
Pros
- The free plan gives unlimited users on a single app, so a team can run the CRM at no license cost.
- CRM data flows natively into Odoo's Sales, Inventory, Invoicing, and Email Marketing apps, so quotes and stock checks happen without third-party connectors.
- Lead tools go beyond the basics, with predictive scoring, quota-based assignment, deduplication, and enrichment.
- It is open source and highly customizable through Studio, the API, or self-hosting.
Cons
- Reviewers often describe the interface and workflows as complex for new users.
- Setup usually needs internal staff or a paid implementation partner.
- Some users report slow performance with large datasets.
- Opinions on support and documentation quality are mixed, and paid support is email-only on weekdays.
