Here is the SYNTH ANATOMY list of the best free Synthesizer plugins for PC & Mac, ranging from virtual analog, FM, and percussive to modular synthesis concepts!
Free Synthesizer Plugins – Highlight 2024: Vital
Vital Synthesizer is like Serum but for everyone. It is one of the best free synthesizer plugins for PC / Mac. Wavetable synthesis merged with innovative features and top-notch sound quality equivalent to big commercial plugins but affordable for everyone.
Better than cracking VST plugins. Furthermore, Vital does not spy on you or install unsafe software on your system in the background. It’s safe and complex enough to occupy you for months or years.
If you want more ready-to-use sounds, you can buy a bundle and support the developer’s work.
Vital is a wavetable powerhouse: it has three oscillators, a sample slot, two filters with 32 types, three envelopes, four audio-rate LFOs, and more. A plug-in with which every hobby and professional musician can design varied sounds without spending much money.
Thus, it’s a must-have for every musician. The full article about Vital is available here.

Another free Synthesizer plugin highlight of this year is the U-he Zebralette 3. It’s still in beta and development, but it’s already the most in-depth wavetable Synthesizer plugin on the market. And it’s free.
Zebralette 3 uses a combination of super flexible wavetable and additive synthesis to generate sounds. Plus, you get various oscillator FX, a multi-segment envelope (MSEG), a classic ADSR envelope, and two LFOs. Delay and reverb refine your sounds.

I hope you have found many new synthesizers in the best free synthesizer plugins list 2024.
Another good place for free plugin news is the website of our friends of Bedroom Producer Blog.
You have to try ArtPyrite,Beatzille (hope I spelled them right)on vstplanet.
Hello Paul
ArtPyrite is only a Windows Synth and doesn’t fit to this list. I consider for this only cross-platform freeware synths. There are hundreds of Windows Synths available but only few for PC & Mac. Beatzille is a unfortunately no longer available for free only via a physical magazine purchase (BEAT Magazine Workzone). Cheers Tom
Good article and some excellent choices. Part of the challenge when starting out is limiting yourself to just a few tools so you don’t get paralyzed by the number of choices. I like that you stuck with synthesizers (not ‘players’ or samplers.)
That said, Synth1 and OBXD would have made my list.
Maybe do a similar article for major effects (best delay, best free reverb etc.) and limit it to two or three good choices….
A similar article on reverbs and delay exist already 😉

https://synthanatomy.com/2017/07/12-free-reverb-plugins-for-pc-and-mac-you-should-not-miss.html
it would be great to have a update log at the beginning or end of the list to see which VSTs were added in the update.
Right but check always the last ones, these are new added 😉
Needs more cowbell…
Will definitely check these out!
How about VCV Rack ?
not a “plugin” but more a modular standalone software and environment. VCV Rack 2 will arrive as plugin not for free.
Yes, you’re right. It’s not a plug-in. I just remembered it’s free 😀
great stuff!
Where’s the Audiospillage MiniSpillage for PC you’re talking about?
it’s only VST & AU for macOS
Olá. Infelizmente o site vstplanet.com não está funcionando mais. Aqueles plug-ins perfeitos foram perdidos…
Why is “cross platform” relevant for a list like this ? I am on Mac and are not interested in PC plugins and probably this is vice versa for the PC owners.
because I took the decision for it. There many other synths out there for Windows, many are made in the Synth Edit or other platforms. They often sound the same and gives me nothing extra. Also often people complain why this plugin or this is not available for macOS or Windows. So I decide just to highlight the synths that are available for both platforms. Thus both user groups are happy.
OK, no offense. The lists as is are useful to me. Thanks.
i would also add beatmachines as it is also samplers basically
AKAI MPC, Sitala, RitMix maybe
and for instr synths i would also add KeeBass and such samplers as SampleTank\Syntronik\Kontakt player, it has some good instruments for example melda also has released MonasteryGrand piano this year.
there is a list for free drum machines etc 🙂 just look in the free section of the website 🙂
in fact i would also add free DAWs, kinda as a basic multi instrument
because they also had some synths sometimes and can be used as samplers and everything
Cakewalk, Tracktion, LMMS, SoundBridge, Ardour, Studio One Prime, Pro Tools First
while it’s better to have no limitations for DAW like qTracktor, but sometimes best means it has better features and stable working.
this list is exclusive to synths!
Check the other lists here

Tom,
now Synful is free of charge, I think it deserves to be added to your list.
not a “synth” but I will add
Pretty cool <3
FYI: the link for Kuma 508 404s (Psytrance…) and Beatassist.eu is squatted.
thanks I will check it
Note that Ujam Usynth DRIVE is no longer free. Ujam now charge $39 for it.
thanks I will fix it
OB-Xd is NOT free, you cannot use it for commercial purposes unless you get a commercial license; this, in my book, means it cannot be considered fully free…
it’s a free download in the non-commercial version. So it’s free Honestly, do you think the developer will come to your PC/Mac if you use the free version in a track 😉 And I have more problems with a developer who updates an open-source plugin and charge for it.
