wp-graphql/wp-graphql

WPGraphQL is a GraphQL API plugin for WordPress that exposes WordPress data through a standards-based GraphQL schema.

The plugin solves the problem of accessing WordPress data in modern development workflows by providing a complete GraphQL interface to WordPress core features including posts, pages, users, and taxonomies. Rather than relying on REST endpoints, developers query exactly the data they need through a single GraphQL endpoint, reducing over-fetching and simplifying client-side data management. The implementation follows GraphQL and WordPress best practices and is designed to be extensible, allowing plugins to add their own schema definitions on top of the core WordPress schema.

Developers should choose WPGraphQL if they are building modern applications on WordPress and want to leverage GraphQL's query efficiency and developer experience. It suits projects ranging from headless WordPress sites to Gatsby integrations to any application that needs programmatic access to WordPress data. The tool distinguishes itself by maintaining a clear scope: core features cover WordPress's built-in functionality and performance optimizations that benefit all users, while plugin-specific integrations and opinionated workflows are intentionally kept as separate extensions. This separation keeps the core maintainable while enabling a rich ecosystem of add-ons for ACF, Yoast, WooCommerce, and other popular WordPress tools.

The project maintains an active development process with a structured approach to new functionality. The team uses an Experiments framework to validate proposed features and breaking changes in real-world conditions before committing them to core, allowing community feedback to inform decisions about stability and backward compatibility. The codebase is organized as a monorepo containing the WPGraphQL ecosystem of plugins and supporting websites, with clear documentation for both end users installing from standard channels and contributors setting up a development environment.
