## Description

Casdoor is a centralized identity and access management platform that functions as an OAuth 2.0 authorization server. It provides a comprehensive suite of services for managing user identities, authentication sessions, and access policies across both web and machine-to-machine applications. Built with a decoupled frontend-backend architecture in Go, the platform supports high-concurrency environments and offers a web-based management interface for administrative tasks.

The platform distinguishes itself through its extensive support for federated identity management, allowing integration with external providers via OIDC, SAML, and LDAP. It enforces granular security through role-based access control, scope-based permission validation, and hardware-backed authentication methods like WebAuthn. Beyond standard identity services, it includes specialized infrastructure for managing AI agent lifecycles, monitoring agent traffic, and securing tool access through delegated authentication.

The system provides a broad capability surface that includes observability and audit logging, event-driven webhook notifications, and automated session management. It also offers developer-focused tools such as CLI-based authentication flows, secure token storage, and software development kits for integrating identity verification into external services. The platform is designed for flexible deployment, supporting configuration via JSON-based data initialization and providing APIs for querying system status and version information.
