Compare AuthZed vs. Kinde

Unlock the potential of your business by utilizing an authorization framework inspired by Google's Zanzibar white paper. The AuthZed team, creators of SpiceDB, offers a robust, enterprise-ready permissions system that is designed to scale efficiently while ensuring security. This solution stands as the most advanced open-source implementation of Zanzibar, crafted for optimal consistency and performance even in large-scale applications. You can define granular access controls for any object within your application or across your entire product suite, all while managing permissions through a unified schema. With the ability to specify consistency requirements for each authorization check, tunable consistency features allow for a balance between performance and accuracy tailored to your specific needs. SpiceDB provides lists of authorized subjects and accessible resources, which can be particularly useful for pre-filtering permission-based outcomes. Equipped with observability tools, a powerful Kubernetes operator, and load-testing functionalities, SpiceDB ensures an emphasis on both developer and platform engineering experiences, facilitating seamless integration and operational efficiency. This comprehensive approach makes it easier for businesses to adapt to changing security requirements while maintaining a focus on user access management.
