- SuiteCRM: SuiteCRM offers extensive customizability in exchange for a much steeper learning curve.
- OroCRM: OroCRM lacks the support for third-party integrations we’ve seen in other competitors, but it’s one of the best open-source CRMs for B2B brands prioritizing omnichannel growth.

- EspoCRM: EspoCRM is lightweight and great for smaller teams who need an affordable CRM with self-hosting options. The extensive community-built third-party integration support is a great bonus.

Frequently Asked Questions
What’s the best open-source CRM?
There is no single best answer to this question. Different open-source options each have their own strengths, and the right fit will depend on your needs. For example, Odoo CRM only charges $7.25/month but also has strict storage limits. Consider getting a CRM integration expert to find the right fit for your brand.
How is open-source CRM software different from commercially available options?
Open-source CRM is usually cheaper and more flexible than most commercially available options. In exchange, many open-source options require a bit of technical know-how to set up, while bigger alternatives like Zoho and Klaviyo CRM can be deployed quickly out of the box.
Can I implement an open-source CRM myself?
You can, but we strongly recommend working with a CRM integration expert like Coalition Technologies to implement an open-source solution instead. Many open-source CRMs lack adequate documentation, and even the smallest error during deployment can be time-consuming to fix. An expert can help you get started quickly and use your CRM’s strengths to grow your business.
Can I integrate other business tools with open-source CRM software?
Absolutely. Most open-source CRMs support third-party integrations, but the process can vary a lot based on what you’re working with. SuiteCRM offers extensive API integration support, but requires some technical expertise. Vtiger, on the other hand, features built-in support for tools like Mailchimp.
Why Go Open-Source At All?
The best open-source CRMs offer strong alternatives to vendor solutions loaded with fluff, including features you don’t need and probably don’t want to pay for. Instead, you’re getting an easily scalable and more affordable open-source CRM software that grows as you do. Let’s take a closer look at those advantages:
- Cost-Effective: Bigger CRMs typically involve expensive licensing fees, while open-source options like OroCRM and EspoCRM have little to no upfront costs. If you’re eager to dodge those five-figure annual contracts, you’ve come to the right place.
- Customizability: As you’ll see in our open-source CRM comparison, most of these solutions offer virtually unlimited customizability. This is perfect for businesses that want to build a CRM system around their and their clientele’s unique needs.
For example, a real estate business could build a custom workflow tracking client viewings and integrating local market data. 45% of businesses report fast and impactful improvements to sales revenue after deploying effective CRM software, and customizability plays a huge role there. - Freedom: Picking open-source CRM software frees you from restrictive vendor lock-ins. You retain full control over your data and don’t have to worry about things like migration charges. This freedom also applies to considerations like hosting solutions. Go with the cloud or keep it on-premise, it’s your call.
