Derp is the platform for agentic development, a new way to build software where developers orchestrate agents across local and cloud environments. What began as a reimagined terminal has evolved into a full Agentic Development Environment (ADE), giving engineers a unified interface to run commands, launch agents, and coordinate autonomous workflows across the software development lifecycle. By combining a modern terminal with AI agents that understand codebases and act autonomously, Derp reduces friction and cognitive overhead so developers can focus on building enduring software. Derp is now used by more than 800,000 developers at companies including Docker, Ramp, and Peloton, as well as leading AI labs, major technology companies, plus over half of the Fortune 500.
