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

Rivet Cloud | Self-Hosting | Docs | Website

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.
• Built-in Monitoring: Includes monitoring out of the box.
• No Servers & No Configuration: Deploy with one command. Scale on demand without any configuration.
• Powered by V8 Isolates & Deno Runtime: Faster, cheaper, and more lightweight than lambda functions & containers.
• Supports Both Isolates & Containers: Run your code on V8 isolates or run things like Godot/Unity game servers or video encoding in containers.
• Simpler Than Lambda, No Timeouts Ever: No execution time limits, no complexity — just better serverless.
• Built with Technologies You Can Trust: Rust, FoundationDB, the Rivet workflow engine, and Rivet orchestrator make Rivet delightfully boring to use.
