Free VST plugins compared

Answer in brief

Ten free instruments and effects across the jobs in a mix, each with its terms and systems taken from the maker’s page.

Studio 56 owns this site and charges for Pro, so its place at the top is our pick for what the free tools cannot do. It is not a measured ranking of every free VST plugin.

What each one does

  • Studio 56

    When no free plugin does what you need, describe the instrument or effect and Studio 56 builds it on Pro, which starts with a free trial. Studio 56 publishes this site, so this is our editorial choice, not an independent review.

    Free trial, then Pro · Mac, Windows

  • Splice INSTRUMENT

    Splice says INSTRUMENT is now where LABS lives. It is free to download and play with a free Splice account, and free presets such as Glass Piano and Tape Piano sit beside paid packs.

    Free tier, paid plans add premium packs · Mac, Windows

  • Vital

    Vital Audio presents it as a visual synth that can also turn your own samples into wavetables. The free Basic pack is the whole synth with a starter set of presets and wavetables.

    Free Basic pack, paid packs available · Mac, Windows, Linux

  • Surge XT

    Its makers call it a sound designer’s dream, with many synthesis methods, filters and effects plus MPE and microtuning. A community of developers keeps it updated.

    Free, open source (GPL-3.0) · Mac, Windows, Linux

  • Valhalla Supermassive

    Valhalla DSP designed it for huge delays and reverbs and says it is free with no strings attached. Its 22 modes run from short dense reverbs to long repeating echoes.

    Free · Mac, Windows

  • TDR Nova

    Tokyo Dawn Records calls it a parallel dynamic equalizer: four bands that each carry a dynamics section, plus high-pass and low-pass filters and a spectrum analyzer.

    Free, GE edition paid · Mac, Windows, Linux

  • TDR Kotelnikov

    Its maker sums up the sound as “stealthy”, able to change dynamic range a great deal while the tone and punch of the source stay intact. Peaks and RMS content get release controls of their own.

    Free, GE edition paid · Mac, Windows

  • Klanghelm IVGI

    Klanghelm says IVGI can be soft enough for the master bus or dense and dirty on a single track, and that it reacts to the input the way its paid sibling SDRR does.

    Free · Mac, Windows

  • Kilohearts Essentials

    Kilohearts gives away a set of compact effects that range from a compressor and delay to distortion and a transient shaper. They work as normal plugins or inside Kilohearts’ own hosts.

    Free with an account · Mac, Windows

  • Youlean Loudness Meter

    Youlean’s meter reads loudness, true peak and loudness range against broadcast and streaming standards. The free version never expires, and Pro adds streaming presets and saved reports.

    Free version, Pro version paid · Mac, Windows

  • Voxengo SPAN

    Voxengo’s free real-time analyzer draws the spectrum in stereo, mono or mid-side. It also shows stereo correlation, true peak level and clipping.

    Free · Mac, Windows

How entries were picked

Apart from Studio 56, which publishes this site, every entry is a well-known name among free VST plugins that its maker describes on an official page we could check. Each description says only what that page says. The order is not a ranking, and being listed does not mean a maker knows about or endorses this site.

Prices and systems change. Check the official page before you buy or install anything. Every page linked here was opened on November 8, 2026.
