Sanity Live CDN is a real-time content delivery network and API that ensures instant propagation of content changes across all connected applications. It eliminates the need for manual cache invalidation, polling, or building custom real-time infrastructure. The system uses a content-aware CDN and Live Content API to automatically update only the changed content, providing fresh data to users even during high-traffic events. Developers can enable live content with minimal code, and the CDN architecture ensures high availability and performance by serving content close to users and handling backend outages gracefully.

Key Features

Real-Time Content Updates

• Instantly propagates content changes across all frontends without manual refreshes or cache invalidation.
• Uses sync tags to update only the changed content, minimizing unnecessary data transfer.

No Custom Infrastructure Needed

• Removes the need for WebSockets, polling, or complex real-time systems.
• Integrates with popular frameworks (e.g., Next.js) using simple utilities and components.

High-Performance Global CDN

• Multi-layered CDN serves content close to users for low latency.
• Remains available and consistent even during backend issues or traffic spikes.

Fine-Grained Cache Invalidation

• Sync tags allow precise cache updates, avoiding full cache purges and stale content.
