A lightweight Ruby API framework with an elegant RSpec-inspired DSL for building clean, fast web services.
Crepe is a lightweight API framework for Ruby that helps developers build clean, fast web services. It provides an elegant DSL inspired by RSpec, making API design intuitive and straightforward. The framework is Rack-based, ensuring compatibility with standard Ruby web infrastructure.
Ruby developers building RESTful APIs or web services who value simplicity, clean code, and an expressive DSL. It's particularly suited for those familiar with RSpec or Grape looking for a lightweight alternative.
Developers choose Crepe for its minimalistic approach, intuitive RSpec-like syntax, and focus on fast, maintainable API development without the overhead of larger frameworks. Its elegance and simplicity make API design feel natural and efficient.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Uses familiar constructs like `let`, `param`, and namespaces to define APIs cleanly, as shown in the GitHub Gist example, making code readable and maintainable for developers accustomed to RSpec.
Built as Rack applications, ensuring seamless integration with Ruby web servers and middleware, which is a standard in Ruby web development for flexibility and deployment.
Supports regex-based constraints directly in route definitions, such as `param(sha: /\h{40}/)`, enabling precise validation without extra boilerplate code.
Provides `rescue_from` blocks to manage exceptions uniformly, allowing custom error responses like `error! :not_found` for better API consistency.
As a lightweight framework, it lacks integrated tools for serialization, authentication, or database ORM, requiring manual implementation and additional gems for common needs.
The project's last significant updates are from 2013-2015, suggesting it may not be actively maintained, which could lead to compatibility issues with newer Ruby versions or dependencies.
Compared to more established frameworks like Rails or Sinatra, Crepe has a smaller ecosystem and relies on a wiki for advanced usage, which might be incomplete or outdated.
