Cockos

Cockos Incorporated is an American software company focused on audio software, best known for creating the digital audio workstation Reaper. Reaper is a cross-platform DAW that runs on Windows and macOS, with community and experimental support for Linux. The company also develops a set of audio plugins and development tools, including the ReaPlugs plugin suite, the ReaScript automation framework, and the JSFX (Jesusonic) audio effect language.

Reaper provides multitrack recording, editing, mixing, and mastering capabilities, with flexible routing, automation, and extensive plugin support. It supports multiple plugin formats, including VST, AU, and others, and ships with a core set of effects and virtual instruments. Reaper is designed for customization and extensibility: built-in scripting via ReaScript enables automation in languages such as Lua and EEL2, while JSFX allows users to write lightweight effects and generators that run within Reaper.

Cockos operates on a shareware model: Reaper is available as a fully functional evaluation, with licensing required for continued use after the trial period. The company releases frequent updates and encourages user feedback, contributing to a rapid development cycle and a feature-rich platform despite a small development footprint.

The company has cultivated a dedicated user community and is recognized for its lightweight, efficient code and flexible workflow, which has contributed to the DAW’s adoption among independent musicians, audio professionals, and researchers.
