Providing an intuitive control plane for modern reverse proxy infrastructure, CaddyUI enables system administrators to manage proxy hosts, automated TLS certificates, and traffic routing without hand-editing configuration files. Operators can create and adjust reverse proxy destinations, URL path rewrites, custom headers, and redirection rules using structured forms that validate against the proxy engine before saving. The platform coordinates automatic ACME certificate requests and renewals, displaying live certificate expiration timelines, validation stages, and internal self-signed certificate authority options for local network services. Fleet management tools synchronize proxy rules across multiple distributed server instances, preventing configuration drift across staging and production clusters. Automated post-deployment health checks verify upstream endpoint availability, HTTP status codes, and latency thresholds, instantly rolling back to the previous configuration if an expectation fails. An integrated observability suite delivers real-time visitor traffic analytics, geographic maps, HTTP response code breakdowns, and single-click client IP blocking to counter malicious probing attempts. Administrators can schedule automated database backups, configure multi-user access with role permissions, and integrate CrowdSec threat intelligence to protect backends.
