# Warestack vs GitHub Copilot

GitHub Copilot generates code inline and reviews PRs. Warestack governs the output — ensuring agent-generated code meets delivery standards, instruction files are enforced, and teams maintain visibility over what ships.

## Copilot writes the code. Warestack governs what ships.

GitHub Copilot is the leading AI code generation tool — but it doesn't govern its own output. Warestack fills that gap: enforcing .cursorrules across all agents (not just Copilot), validating PR intent, and giving leaders delivery-level visibility. They're designed to work together.
