Rivet

Revolutionary approach to stateful backend development that moves beyond the limitations of traditional serverless functions. Instead of fetching data from remote databases for every request, Rivet keeps your application state in memory alongside your compute logic.

Key advantages over traditional architectures:

• Sub-millisecond latency for reads and writes with in-memory state management
• Built-in realtime capabilities using WebSockets without additional infrastructure
• Automatic persistence that handles state changes and replication seamlessly
• Cost-efficient scaling with actors that sleep when idle and wake instantly on demand

Developer-friendly features include live state inspection, network monitoring, event tracking, and an interactive REPL for debugging. The platform supports multi-region deployment for ultra-low latency responses at the edge.

Flexible deployment options range from self-hosting with a single Docker container to fully managed cloud services. The open-source Apache 2.0 licensed codebase is built in Rust for performance and safety, integrating seamlessly with existing TypeScript applications and infrastructure stacks.

Perfect for chat applications, multiplayer games, collaborative documents, user sessions, and any workload requiring persistent state management with realtime updates.
