caniuse is a data repository that provides raw browser and feature support information from caniuse.com.
The repository addresses the need for programmatic access to browser compatibility data. It serves as the source of truth for caniuse.com's support tables, allowing developers to query which browsers support specific web features. The data is structured in JSON format and includes comprehensive support information across browsers and features, with some data sourced from browser-compat-data.
Developers should use this repository when building tools that need to reference browser compatibility information, such as linters, build tools, or documentation generators. The data is available under a CC BY 4.0 license, requiring only attribution to caniuse.com. The repository also accepts contributions from the community to update or correct support data, making it suitable for projects that want to stay current with evolving browser capabilities.
The project maintains a substantial user base that actively reports issues and requests data corrections. Response times to issues and pull requests typically range from one to two weeks. The majority of tracked work consists of support data suggestions, site requests, and data correction inquiries, indicating that maintenance efforts are primarily driven by user feedback rather than internal roadmap changes.
