PromptEngine

PromptEngine is a Rails engine that treats prompts as first-class citizens in your application. Instead of scattering AI prompts throughout your codebase, PromptEngine provides a structured way to manage, version, and deploy prompts.

The core insight is simple: prompts are data, not code. They should be versioned, tested, and deployed separately from your application logic. This allows non-engineers to iterate on prompts without requiring code deployments.

Key features include version control for prompts, A/B testing capabilities, composable prompt workflows, and a clean admin interface for prompt management.
