Compatibility
The tested HTTP target is better-auth@1.7.6. The pinned runtime and official client define expected endpoints, payloads, errors, cookies, and authentication behavior.
Rust schemas, database models, plugin builders, delivery callbacks, and Axum extractors are native APIs. Use the plugin catalog and generated OpenAPI to inspect the implemented surface. Newer upstream docs may describe features outside this target.
See the compatibility guide for the test contract and native integration audit for embedding behavior.
