5 Best Open Source Helpdesk Software in 2025

A regular helpdesk software records customers’ complaints as support tickets, assigns them to support executives and closes the tickets once the issues are resolved. An open source helpdesk software does all that with a little twist: its source code is available publicly. You can install and modify this source code as you need. 

So, is an open source helpdesk valuable software for support teams? The answer is yes and no. 

‘Yes’ because it is available free of cost and provides lots of customization opportunities. ‘No’ because an open source helpdesk software is challenging to set up if you don’t have sound technical expertise. 

Does that sound confusing? We are here to fix things for you. 

This guide will shortlist the best open-source helpdesk solutions for customer support leaders and assist in determining whether an open source helpdesk ticketing software is needed. 

Let’s get started.

What is open source helpdesk?

An open source helpdesk ticketing system converts your external (think customer queries, complaints and feature requests) and internal (employees’ queries, questions and concerns) support requests into tickets. It sorts these tickets with relevant tags, adds priority filters to the tickets and assigns them to the concerned support executives for timely resolution. 

The code used to build an open source helpdesk system is publicly available for installation. This enables support teams to modify certain features of the tool and shape it according to their own requirements.  

Why is open source helpdesk software important?

Customizable according to specific use cases: The primary goal of opting for a helpdesk ticketing system is to resolve queries faster with less back-and-forth communication. However, the use cases for support teams vary. 

For example, you may want to templatize popular customer queries and solutions to avoid addressing them repeatedly. With an open source helpdesk, you don’t need to request this feature separately. Since you have the source code available, you can customize it. 

Most open source tools have free plans: The source code for most open source ticketing systems are available for free. You can download the code and modify or re-distribute it without spending as much as you would with a conventional help desk. Additionally, all the open source ticketing tools we will list in the next section offer free plans. While some of the free plans are subject to minimum cap, these tools are good to start with. 

Huge support community: Personalized support is not usually an option for open source helpdesks. However, most of these tools come with strong community support. You can reach out to past users and technical professionals on Discord or Slack communities whenever you have any doubts or get stuck while developing the source code.

Is an open source helpdesk system worth investment?

Investing in an open-source helpdesk has its fair share of advantages and limitations. The advantages are affordability, more customization options, and community-driven support. 

The disadvantages are as follows: 

Exhaustive set-up process and complex user interface

If you are not a skilled developer, setting up some of these open source ticketing systems can be challenging. Unlike regular B2B software, there won’t be a dedicated customer success executive to guide you through the onboarding process. You might have to hire a new resource to set up the software and improve the support team’s adoption rate. 

Alternatively, most open source software is designed for developers. This makes it extremely difficult for end-users as the UI is often outdated and the tool is difficult to navigate. 

1:1 support is not available

Not every issue can be resolved with community support. Some issues are specific to a company, and sharing such confidential information with community members is strictly impossible. In fact, community members can assist you with their experiences, but for specific use cases and queries, team members require close 1:1 support. This is mostly missing from most open source helpdesks. 

Sometimes ‘free forever’ is simply an eyewash. There are hidden costs involved

While most open source helpdesk software identifies as ‘free forever’ tools, this is not always true. There are either hidden costs or hidden terms and conditions available that make these tools expensive. For example, Tidio offers a free plan, but it only handles 50 conversations per month. This can be a massive limitation for growing companies, forcing them to opt for premium plans instead. 

As your customer base grows, you will need a scalable helpdesk software that accommodates more conversations. Usage limitations or hidden costs can be a major roadblock.
