The ApiClarity repository, hosted on GitHub at https://github.com/openclarity/apiclarity, is an open-source tool designed to help organizations analyze and understand their API traffic. It provides comprehensive insights into the APIs being used across an organization's infrastructure, enabling better governance, security, and efficiency in managing API interactions. The primary goal of ApiClarity is to deliver enhanced visibility into API usage patterns without requiring modifications to existing applications or services.

ApiClarity leverages passive monitoring to collect data on API traffic, which means it does not inject any code into applications. Instead, it captures HTTP(S) and WebSocket traffic passing through a network gateway or proxy, making it an unobtrusive solution for observing APIs in production environments. This approach ensures that organizations can gain insights without disrupting ongoing operations.

The tool is capable of identifying API calls from various sources within the organization's network, providing detailed analytics on these interactions. ApiClarity can categorize and tag APIs based on their functions and usage, helping organizations understand how different parts of their infrastructure communicate with each other. This information is crucial for optimizing API performance, enhancing security protocols, and ensuring compliance with relevant regulations.

One of the standout features of ApiClarity is its ability to detect undocumented or shadow APIs—APIs that are not officially documented but are in use within an organization. By identifying these hidden endpoints, organizations can address potential vulnerabilities and align their API management practices more closely with their overall IT strategy. This capability is particularly valuable for maintaining security compliance and minimizing risks associated with unauthorized API usage.

ApiClarity offers a user-friendly interface that presents its findings in an easily digestible format. Organizations can access real-time dashboards and reports that visualize API traffic data, enabling stakeholders to make informed decisions quickly. The tool supports various export formats for further analysis or integration with other systems, enhancing its utility as part of a broader IT management framework.

The project is developed under the Apache License 2.0, promoting open collaboration and contribution from the community. This license allows users to freely use, modify, and distribute the software, fostering innovation and continuous improvement through community-driven enhancements. The repository includes detailed documentation that guides users on how to set up and deploy ApiClarity in their environments.

Overall, ApiClarity serves as a powerful asset for organizations seeking to optimize their API management practices. By providing deep insights into API traffic with minimal disruption to existing systems, it empowers IT teams to improve security, efficiency, and compliance across their digital ecosystems.
