Apigee API hub vs Zally

Apigee API hub centralizes API information so teams can discover, assess, organize, and manage an organization's API portfolio. Catalog entries can capture versions, specifications, operations, deployments, dependencies, and lifecycle details. Search supports filters and LLM-based free-text queries across API definitions. The hub parses OpenAPI specifications into definitions and operations and can provide linting feedback on imports. It can import proxy information from Apigee and Apigee hybrid projects, with synchronization scheduled every six hours. Other supported sources include Google Cloud API Gateway, Apigee Edge, and preview plugins for AWS API Gateway and Azure API Management; custom plugins can connect on-premises or multicloud sources. VPC Service Controls can constrain ingress and egress, and instance and search-data locations can be selected during provisioning. Advanced API Security is an additional add-on for risk assessment across multiple Apigee organizations, environments, and gateways, with some features excluded in multi-gateway use. The dashboard requires at least five registered APIs. Eligible Apigee organizations in supported regions can use it at no additional cost; pricing is also listed from $13, with a 60-day trial.

Zally is an API linter and quality assurance tool for OpenAPI specifications. It supports OpenAPI 3 and Swagger OpenAPI 2, with a RESTful API, command-line interface, and web interface. Its standard configuration checks APIs against Zalando’s RESTful Guidelines, and the project says it can also be used out of the box by others. Teams can enable or disable server-side rules, configure some existing rules, or implement their own in Kotlin. An API definition can use the x-zally-ignore extension to disable rules for that API. The web interface lists implemented rules and can lint external files and API definitions in its online editor. The project describes starting the web UI, server, and database together using Docker Compose. It also lists an unofficial Zally Maven Plugin integration. Maintained by Zalando, Zally is offered under an MIT license with an exception. Its Open source plan costs nothing.
