Scalable. Stateful. Serverless.

Rivet is the platform to build realtime, edge, or agent applications.
No limitations of Redis or timeouts of Lambda.

Intro

Rivet comes with simple primitives to build your backend. Leverage Rivet Actors to build complex functionality with ease.

Features

• State & Persistence: State that feels like memory but works like storage. Ideal for dynamic, fast-moving apps.
• Remote Procedure Calls: Lightweight messaging built for speed. Complete client/server type safety included.
• Runs Forever, Sleeps When Idle: Always available, sleeps on network inactivity or timeouts, and wakes instantly on demand.
• Edge Networking: Automatically distribute your applications near your users for ultra-low latency.
• Fault Tolerance: Ensure application & state resilience through crashes with zero downtime.

Infrastructure

• Works with Your Runtime: Supports V8 isolates, WebAssembly, and containers to work with your existing tools.
• Scales to Zero: Handle millions of connections with low latency and high-throughput writes while saving costs through instant actor sleep/wake cycles.
• No Servers & No Configuration: Deploy with one command. Scale on demand without any configuration.
• Simpler Than Lambda, No Timeouts Ever: No execution time limits, no complexity — just better serverless.
• Batteries Included Monitoring: Includes monitoring out of the box, or bring your own monitoring.
• Built with Technologies You Can Trust: Rust, FoundationDB, the Rivet workflow engine, and Rivet orchestrator make Rivet delightfully boring to use.

Use cases

• AI agents
• Game Servers
• Collaborative applications
• Local-first apps
• Discord Activities
• Chat Apps
• Yjs Sync & Storage
• Sandboxed Code Execution
