FusionAuth is the authentication and authorization platform engineered for developers who demand flexibility and control. Built from the ground up to integrate with any stack, every feature — from user registration to MFA and SSO — is exposed via a modern, well-documented API.
Support for every major identity protocol is included out of the box: OIDC, SAML, OAuth2, JWT, passwordless login, social sign-on, and more. Whether you’re building a greenfield app or retrofitting auth into a legacy system, FusionAuth adapts to your use case — not the other way around.
Need compliance? FusionAuth helps you meet GDPR, HIPAA, and COPPA standards quickly and reliably.
Deploy it your way: install on Linux, Windows, macOS, Docker, or Kubernetes — or go with FusionAuth Cloud, our managed SaaS hosting. No black boxes. No vendor lock-in. Just powerful, customizable auth that works the way you do.

Prefect Horizon
Prefect Horizon serves as a managed AI infrastructure platform within the extensive Prefect product ecosystem, enabling teams to deploy, govern, and manage Model Context Protocol (MCP) servers and AI agents on an enterprise level with essential production-ready capabilities like managed hosting, authentication, access control, observability, and governance of tools. By leveraging the FastMCP framework, it transforms MCP from merely a protocol into a comprehensive platform featuring four integrated core components: Deploy, which facilitates the rapid hosting and scaling of MCP servers through CI/CD and monitoring; Registry, which acts as a centralized repository for first-party, third-party, and curated MCP endpoints; Gateway, which provides role-based access control, authentication, and audit logs to ensure secure and governed access to tools; and Agents, which offer user-friendly interfaces that can be deployed in Horizon, Slack, or accessible via MCP, allowing business users to engage with context-aware AI without requiring technical expertise in MCP. This multifaceted approach ensures that organizations can effectively harness AI capabilities while maintaining robust governance and security protocols.
