Designed with developers in mind, FusionAuth integrates seamlessly with any language, framework, or architecture. Every capability is API-first and built for extensibility, so you can tailor authentication workflows without getting locked into rigid, inflexible systems. FusionAuth supports all the key use cases — user registration, multi-factor authentication (MFA), passwordless login, role-based access control, and more — while helping you stay compliant with GDPR, HIPAA, PCI, and other regulatory standards.

TelemetryOS is a vertically integrated platform for connected screens, kiosks, and screen applications. Purpose-built Node hardware, a hardened Edge operating system, Studio cloud, an integrated video CDN, and an application runtime work together so every display can show the right content, respond to real-world conditions, and scale from one location to thousands. Start with what every screen network needs: playlists, dayparting, calendar schedules, priority overrides, and a media library delivered through adaptive 4K streaming. Content caches locally so playback continues through outages. Proof-of-play reporting, screenshot capture, and audit logs verify what ran, where, and for how long. Design multi-zone layouts, video walls, and touch kiosks on a visual canvas, with scheduling built into each page and AI Assist to generate layouts from a prompt. Instant, scheduled, or CAP-triggered emergency overrides can preempt content on any screen or group. When playlists are not enough, TelemetryOS runs full screen applications. Developers build in React and TypeScript with the TelemetryOS SDK, preview across aspect ratios, and publish from Git with staged rollouts and one-click rollback. Screens connect to POS, ERP, sensors, serial devices, and MQTT so menus, dashboards, and kiosks update from live business data. Fleet health monitoring, remote diagnostics, automatic OS updates, role-based access, SAML SSO, and SOC 2-aligned enterprise controls keep operations predictable at scale. Use TelemetryOS for campaign walls and retail media, QSR menu boards and self-service kiosks, healthcare check-in and wayfinding, campus communications, production wallboards, hospitality directories, and corporate KPI displays. Node Mini, Node Pro, and Node Max cover single-screen 4K signage, multi-display apps, and on-device AI workloads—all managed from one console. Built on a decade of operating mission-critical screens, TelemetryOS powers tens of thousands of displays in 40+ countries with a 99.9% uptime SLA.
