Plugin Boutique is a Brighton, UK-based online marketplace and plugin developer launched in 2012 by Loopmasters co-founder Matt Pelling and Gareth Halsall. The platform was conceived as a central destination for music producers to discover, buy, and manage software plugins across hundreds of brands — offering a single login for all purchases. It serves producers, musicians, and DJs worldwide and has grown to distribute VST, AU, and AAX plugins from more than 200 software companies.

Beyond operating as a marketplace, Plugin Boutique develops its own line of in-house software tools. Its flagship product, Scaler, is a chord and harmony assistant that maps music theory concepts — scales, modes, progressions — into an intuitive MIDI plugin aimed at both beginners and experienced composers. The product line expanded with Scaler 2, Scaler EQ, and VirtualCZ, a phase distortion synthesizer inspired by Casio's CZ series from the 1980s, used extensively in techno, house, and synth-pop production.

Plugin Boutique was acquired by Beatport as part of its purchase of Loopmasters in 2020, becoming part of the Beatport Group. The company maintains an active presence across social media with tutorials, plugin demonstrations, and production content.

Plugin Boutique has 123 products cataloged on Equipboard, including Expansion Packs, Soft Synth Presets, and DAW Template Plugins. Their gear is featured by 16 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include Disclosure, Hardwell, and Carl Cox.
