SuperflyDSP is a non-commercial audio software project that develops free VST3 and Audio Unit plugins for Windows, macOS, and Linux, built around the tagline "digital processing, analog feel." The project is run in the founder's spare time, drawing on a background in electronics engineering and experience in fields such as railway automation and medical instrumentation, with software offered free of charge for any use but not permitted to be resold.

The catalog focuses on analog-inspired effects organized into two families. The Flying series covers modulation and time-based effects — Flying Wahwah (a stereo automatic wah), Flying Chorus, Flying Phaser, Flying Tremolo, Flying Delay, and Flying-Reverb, the last of which bundles around a dozen reverb algorithms including a shimmer mode unusual for a free plugin. The Lost series leans into lo-fi character with Lost-Tapes (tape emulation), Lost-Vinyls (vinyl noise and artifacts), and Lost-Sampler (a vintage digital sampler emulation).

SuperflyDSP's plugins have been covered by outlets including Bedroom Producers Blog, KVR Audio, gearnews.com, and Synth Anatomy, and circulate widely on freeware aggregators such as Plugins4Free and Looperman as accessible options for producers seeking vintage-flavored color and modulation without a commercial license.

SuperflyDSP has 2 products cataloged on Equipboard, including Reverb Plugins and Phaser Plugins.
