DevilDev is a spec-driven architecture workspace that helps developers design systems before writing code.

You can turn a product spec into a complete software architecture or generate architecture directly from an existing repository - in minutes.

Instead of jumping straight into implementation and fixing mistakes later, DevilDev lets you:

• Generate system architecture from product specs

• Reverse-engineer architecture from an existing codebase

• Break architecture into executable Pacts (features / bugs / tasks)

• Convert Pacts directly into GitHub issues

This creates a development workflow that goes:

Architecture → Pacts → GitHub Issues

or

Prompt → Architecture → Spec → Coding

DevilDev is open-source and already used by 1300+ developers with growing community contributions.

Build faster - without building the wrong system first.
