HoRNet Plugins is an Italian audio software developer based in Colle di Val d'Elsa, Tuscany. The company was founded in 2011 by programmer and electronic music producer Saverio Vigni, who released his first plugin, ChannelStrip, to cover his own mixing needs before expanding the catalog for studio friends and the wider production community. Development is still led by Vigni, with Federica Bogi handling marketing and communications.

The company specializes in affordable VST, AU, and AAX plugins for mixing and mastering, alongside iOS and iPadOS apps. Their catalog spans equalizers, compressors, modulation effects, character processors, reverbs, and utilities, including titles such as HoRNet ChannelStrip, TotalEQ MK2, HarmoniQ, ZeroEQ, TrackShaper, Harmonics, VHS headphone correction, and the ray-tracing reverb Spaces MK2. HoRNet also operates an online AI mastering service and distributes a range of free plugins.

HoRNet has built a reputation for low-priced, focused tools aimed at home studio users and working engineers, often packaged in bundles like the ZeroBundle. The company has been covered by outlets including MusicRadar, Future Music, and Production Expert.

HoRNet Plugins has 21 products cataloged on Equipboard, including EQ Plugins, Utility Plugins, and Compressor Plugins.
