The Ultimate List of Free Pro Tools Plugins 2023

If you’re looking for third-party plugins to expand your growing collection, look no further than The Ultimate List of Free Pro Tools plugins.

Whether you need a Pultec-style EQ or a trigger gate for electronic music stutter effects, this list has it all! Virtual instruments, amp simulators, modulation effects, EQs, compressors, and everything else you might want is here. Most of them are also available in formats like VST, so if you’re using a DAW other than Pro Tools, these plugins will still be compatible.

The best part: all of these plugins are completely free to download and use! They’re organized alphabetically by developer name with brief descriptions of, and links to, each plugin.
