Metabase 58 consolidates embedding options into two clear paths: Modular Embedding for individual components (supporting both Guest mode with JWT signing and SSO with full user accounts) and Full-app Embedding for the entire application (SSO only). Existing embeds continue working without code changes. Static embedding maps to Modular Embedding Guest mode, while Interactive embedding becomes Full-app Embedding. The update includes an in-app setup wizard and a React SDK, with an easier upgrade path from Guest to SSO embeds.
