Moderne: The Platform for Multi-Repository Agentic Workflows

The Problem

AI coding agents are powerful but fundamentally single-repository tools. When an organization needs to make changes across dozens, hundreds, or thousands of repositories—whether migrating frameworks, fixing vulnerabilities, or enforcing standards—they face a gap:

How many places does my birthday exist in our source code?
