The Zammad Tool Stack: Open Source All the Way!

Zammad supports the Open Source Philosophy – and, as a result, relies mostly on free tools. Find out why we’d recommend the same to you, and which tools tips we have.

What this post is about

  • The Open Source idea is all about transparency
  • Self-hosting tools ensures higher security and GDPR-friendliness
  • Most famous SaaS tools can be replaced with an open-source alternative
  • We’re listing our favorite tools to help you get started

Over the course of the past – oh dear, has it already been almost six years?! - Zammad has become a household name in the Open Source Community. Ever since our software was first launched back in 2016, we’ve steadily grown by an average of 80% in both customer numbers and revenue.

When people first learn about Zammad, they often ask the same two questions: How can you survive if you’re giving your code away for free? (That’s something we’ve talked about in our blog post on the Zammad Community.) And: If the Open Source philosophy is so important to you, does that mean you only use free software internally, too? And the answer is simple: of course we do!

Why does the Open Source idea matter to us?

Transparency matters a lot to us. We truly believe that if you build something cool, you should share it with everyone. Some people will forever use it for free but they will return the favor some other way – e.g. by spreading the word about your product or by fixing bugs for you. Others might lend you a hand and pay for enhancements or support services.

We have come to know the Open Source Community as tight-knit and supportive. If you win users over once, they will remain loyal to your product as long as you can keep (or improve) your standard. They appreciate that free software is honest. With everything out in the open, there is not much you can hide, and thus there is only a very small chance of nasty surprises.

In order to keep the Open Source Community thriving, it’s inevitable that free software must be used and advertised – and we are more than happy to do so!

Why should you choose open-source tools?

If the reasons above weren’t enough to convince you yet, we’ve got some more up our sleeves. Of course, Open Source isn’t just about sharing everything freely – data security plays a major role, too!

Besides the transparency and the adaptability that comes with free code, you should also consider the factor that open-source tools can be hosted on your own servers. This gives you maximum control over the security of your software and, almost more importantly these days, your data! The relevancy of GDPR-friendliness is ever-growing. By self-hosting your tool stack, you’re a massive step closer to meeting all necessary guidelines.

Which software does Zammad use?

As mentioned in the introduction, we’ve been around for a few years already (in fact, it’s probably time we splurged on a good anti-wrinkle cream…). We’ve learned many lessons, but the most important one for this particular article is: There is an open-source alternative for every well-known tool out there!

Sounds unlikely? Well, as we said, we believe in full transparency – so let’s take a closer look at Zammad’s tool stack!
