Top 11 Best Eurorack Module Synth Brands In The World 2024

Since 2018, Eurorack has been the dominant hardware format for modular synthesizers. The popularity of Eurorack has brought plenty of module options and manufacturers to the market. Companies large and small offer Eurorack modules, and many even supply DIY kits.

When it comes to knowing the brands to look out for in Eurorack, there's a lot to sift through. There are plenty of brands that enter and exit the market within short periods of time. In contrast, others have solidified their position as top companies in this favoured yet niche modular synthesis environment.

In this article, we'll have a look at the top brands that produce Eurorack modules.

The Top 11 Best Eurorack Module Synth Brands Are:

1. Mutable Instruments
2. Intellijel
3. Make Noise
4. Cwejman
5. Erica Synths
6. Doepfer
7. ALM Busy Circuits
8. Xaoc Devices
9. 4ms Company
10. Tiptop Audio
11. Behringer

Of course, any “best of” list is subjective by nature. I've done my best to make this as objective as possible. I've included not only my own bias but also the opinions of others (in real life, in online forums, and by which brands professionals use). I've also taken into account the number of models and the objective nature of the models in each brand.

We'll get into each of these brands in greater detail to explain why they made this list. I'll also include several module examples for each brand, along with a link to their official website and a bit of the company history.
