Bump.sh
Automated API documentation and changelog platform for OpenAPI and AsyncAPI.
About Bump.sh
Bump.sh is a specialized API documentation platform that focuses on automation, tracking changes, and supporting both synchronous and asynchronous APIs. It is designed to act as a single source of truth for API contracts, generating developer portals directly from OpenAPI and AsyncAPI specifications.
A standout capability of Bump.sh is its automated API changelog. Whenever an API specification is updated via CI/CD, Bump.sh analyzes the diff and automatically generates a human-readable changelog, notifying developers of new endpoints, deprecated parameters, or breaking changes. This ensures consumers are always aware of how an API is evolving.
