The product catalog spans a wide range of categories, from analysis and metering tools like FreqAnalyst and StereoScope to creative effects and processing plug-ins such as Late Replies (a delay/reverb workstation), Destructor (distortion and amp modeling), and Axiom (a multi-effects processor for guitar and bass). One of their most well-known products is PatchWork, a universal plug-in patchbay capable of hosting up to 64 plug-ins within a single instance, enabling complex serial and parallel routing inside any DAW. Other notable tools include Plug'n Script, which allows users to create custom audio and MIDI effects through scripting, and MB-7 Mixer, a multiband mixing console with built-in plug-in hosting.

Blue Cat Audio also maintains a generous freeware lineup, including Chorus, Phaser, Flanger, Free Amp, FreqAnalyst, Triple EQ, and the Gain Suite, all offered without restrictions.
