OpenSpec is a lightweight and configurable framework designed for creating and managing software specifications. The framework aims to keep development teams and coding agents aligned as software requirements evolve.
OpenSpec provides lightweight framework for managing software specifications with AI agents
By using OpenSpec, developers can capture what they intend to build in a specification, refine those requirements, and validate that the specifications describe the correct functionality. Additionally, the framework provides a way to verify that the final implementation matches the original specification.
The project has gained significant community traction, reaching 68,000 GitHub stars and being used by more than 265,000 developers monthly. Data indicates that a new specification is created using OpenSpec approximately every two seconds.
