API Hub

API Hub is an all-in-one platform for the complete API development process. It lets you design APIs using a visual editor or code, test them automatically, create documentation, and share with users through branded portals.

The platform works with OpenAPI and AsyncAPI standards, supporting both traditional REST APIs and event-driven architectures. It includes tools for checking that your APIs follow your team's rules, generating mock servers for testing, and validating contracts between services.

Teams can work together with version control, commenting features, and role-based permissions. The platform connects with popular development tools like GitHub, CI/CD pipelines, and API management systems. Whether you need basic API design or complex enterprise workflows, API Hub provides the features you need.

Confluence

Confluence is an online workspace where teams create and share documents, project plans, and company knowledge. You can think of it as a shared notebook that your entire organization can access and update together.

It works in your web browser or through mobile apps. You build pages using a simple editor that looks similar to Microsoft Word or Google Docs. These pages can include text, images, videos, and links to other tools. You organize pages into spaces for different teams or projects.

The platform includes whiteboards for brainstorming, databases for organizing information, and templates for common documents. With AI features built in, Confluence can summarize long pages, help you write content, and quickly find information across all your team's documents.
