We list the best open source CRM solutions, to make it simple and easy to manage your customer relationships, without needing a subscription.
Given the many different tools that represent the best CRM software on the market today (as well as the complex functionality on offer), it is understandable if businesses see the solutions as cut-off from their internal operations - as residing in the world of external developers, but for which there’s no need to gain a more detailed understanding.
However, the world of open source has changed all that. Open source technologies are those where the source code has been released for free to the wider community. Unlike proprietary solutions, open source CRMs are free if you host them yourself, making many of them stand out as some of the best CRMs for startups. Although it's worth bearing in mind that fees are charged if you use an external cloud hosting provider. This means this is also a great list to browse if you are looking for the best free CRM software on the market.
Open source CRM solutions offer many of the same features that businesses have come to expect from other CRM tools. Lead tracking, sales management, and automation can all be found here, but due to the fact that the source code for open source CRM tools is available online, they usually offer more customization and flexibility.
This is because any company with the right programming skills can examine and alter the code at the heart of its chosen open source CRM. Unlike proprietary software, open source CRM solutions aren’t meant to stand as black boxes. Anyone can open them up and take a look inside.
So, whether you’re on the lookout for the best cloud CRM software, the best sales CRM, or any other type of CRM, don’t disregard open source tools as an option. Also, don’t forget that we’ve also got buying guides for the best CRMs for small business, a guide to CRMs for real estate, and a guide to CRMs for insurance firms.

Best open source CRM overall
Originally emerging as a fork of SugarCRM’s now-defunct open source version, SuiteCRM has acquired plenty of dedicated followers of its own - and not just those that previously enjoyed using SugarCRM,
In terms of features, SuiteCRM offers all the tools that businesses need for sales, marketing, and more, with a number of customization options allowing businesses to design and create an interface that suits their needs. It’s easy to craft a real-time dashboard so you can follow various metrics check on project statuses, and access data-based insights.
Aside from the functionality on offer, SuiteCRM has also enjoyed impressive popularity because of how flexible it is. SuiteCRM works on Windows, OS/X, Ubuntu, Android, and iOS operating systems, so it’s likely that you’ll be able to make the most of SuiteCRM regardless of the device you most commonly use.
SuiteCRM’s flexibility is also on show in terms of the wide range of add-ons available, including AI tools, eSign software, and more, so it’s likely that you’ll be able to apply it to your project, regardless of complexity. This is also a hugely intuitive CRM, which is easy to use - another factor in its popularity. Ease of use is also not something that is necessarily associated with open source tools, so the fact that the learning curve is not particularly steep is to be welcomed.
Updates for SuiteCRM are also issued pretty frequently so there’s less of a need to worry about SuiteCRM becoming out of date. There are some drawbacks - mainly with support and a lack of integrations. But this is still a robust, free open source tool that is worthwhile for any business that is looking for a new CRM tool and has grown frustrated with the proprietary options on the market.
Best open source CRM for support
One of the major advantages of using open source software is gaining access to the vibrant and extensive open source community. This is especially noticeable with Vtiger, which has more than 4.5 million downloads on SourceForge, a web service specifically for open source software. As such, Vtiger has a huge number of developers and users who are familiar with the software, many of which are happy to offer assistance if needed.
In terms of features, Vtiger users will gain access to email marketing functionality, calendar reminders, and automation features. The functionality on offer here will help businesses track leads, shore up customer relationships, and identify new opportunities. The fact that Gmail integration is included is another nice touch too.
Regarding Vtiger’s downsides, the user interface isn’t the most intuitive and larger businesses might find that it isn’t ideal for bigger client numbers or multiple sales pipelines. It’s also worth noting that Vtiger does offer a subscription service as well as an open source one. So, if you broadly enjoy Vtiger’s CRM but don’t feel like you have the in-house resources to tinker with its open source features, this might be a decent option for you.
Best open source CRM for flexibility
Another open source CRM that is worth your consideration is OroCRM. Based on the Symfony2 PHP framework for web development, OroCRM comes with a range of customer management, reporting, analytics, and other features.
Perhaps most impressively, a number of developers have praised OroCRM for having code that is easy to understand and change. This, after all, is what open source software should be all about - providing new levels of transparency and adaptability that democratize the software landscape. That’s certainly the case with OroCRM.
Other strengths of OroCRM include the ability to record customer credentials and all communication, which is sure to be hugely beneficial for your sales team. The integration of an anti-spyware module also means that businesses can feel a little more at ease about storing their customers’ sensitive information. Integration with third-party applications is also straightforward, including Zendesk, MailChimp, and many others.
Because OroCRM is so open about its coding, it also offers businesses the option of creating their own bespoke white-label CRM built on OroCRM. This allows businesses to create a unique CRM tool without having access to expert in-house development personnel. Many of the most popular CRM components are available out-of-the-box, but there’s no end to the number of customizations on offer. Everything is customizable whether you’re a business or a value-add reseller.
Best open source CRM for contact management
First of all, YetiForce doesn’t claim to be an open source CRM that is geared towards the novice user. Some individuals have complained that tutorials and manuals are limited at best and some functionality could be developed further. However, if businesses have a fair deal of tech expertise at their disposal, they’ll find that YetiForce is a fantastic open source CRM.
Forked from Vtiger originally, YetiForce has developed into a distinct CRM tool thanks to extensive community development. There is also the option of paying for additional support and hosting capabilities. If that doesn’t appeal, ongoing refinement is constantly being offered via the YetiForce open source community.
Data is displayed in real-time, with the CRM boasting a number of different widgets, from a calendar to lead tracking, so there is plenty of flexibility on offer - especially as users can even create their own widget. The amount of customization may be daunting for some teams but as long as you have access to some developer expertise - either internally or from third-party support, you should be fine.
YetiForce works particularly well as a piece of contact management software. Organized around six different modules, YetiForce’s contact management functionality lets organizations manage their Leads, Accounts, Partners, Vendors, Competition, and Contacts. These modules can also be integrated with third-party tools, so you can manage all your data and communications from a single platform.
With its beautiful design, YetiForce has plenty to entice users. So although you do need a bit of expertise to get the most from this CRM, once you get to grips with the platform, you can enjoy a holistic open source CRM that is well-designed and well-functioning.
Best open source CRM for documentation
There’s no doubt that opting for a self-hosted open source CRM brings with it a number of advantages. There’s much more freedom to be had from this approach - but also a lot more responsibility. Fortunately, EspoCRM offers some extremely helpful documentation so you won’t feel like you’re on your own if this is the approach you opt for.
This documentation covers everything from sales automation to inventory management. There’s detailed lead tracking functionality on offer, contact management, and a social stream that allows your entire team to follow a particular customer record.
There’s also some robust analytics functionality included with EspoCRM. Users can generate two kinds of reports (List and Grid), with all reports available for display on the dashboard or export to Microsoft Excel.
As well as its detailed documentation, EspoCRM offers excellent paid support but more minor issues can usually be solved via the customer portal free of charge. And, as with other open source CRM tools, the community is also on hand to help.

Best open source CRM FAQs
Which open source CRM is right for you?
First of all, businesses have to decide whether open source tools are right for them. There are undoubted benefits, but it’s understandable if businesses would rather forego the hassle and simply opt for a proprietary solution.
If you have decided that open source is the way to go, some tools are more accessible than others. Do your research and seek out the advice of the open source community. They are a great resource and should help you decide on the right CRM.
How we tested the best CRM software
When we review CRM software, we look at indicators including feature set, interface and ease of use, plans and pricing, and support options.
A high level of automation capability in managing leads, deals, and workflow is an example feature that could contribute towards a high score. Another important strength would be a desktop and mobile interface allowing quick, intuitive access to basic features.
We look at pricing plans and competitors to check whether higher subscription prices are warranted by features you can’t find elsewhere in the market, or whether a good deal could benefit those with lower budgets.
Generous customer support options are also prioritized, especially for CRM software which may come with a steep learning curve.
