Open Source Alternatives to Cloudflare Workers

Rivet is an open-source serverless platform designed to make deploying and scaling AI agents, complex workloads, and backends effortless. It provides a frictionless experience for developers, allowing them to run applications anywhere—whether on the cloud, their own infrastructure, or a hybrid environment. Rivet combines powerful primitives like serverless functions, durable actors, and secure containers into a unified platform, giving you the flexibility to build anything from real-time apps to AI-powered services.

Key features of Rivet include:

• Serverless Functions: Deploy APIs and edge computing workloads that scale automatically, with support for HTTP, WebSocket, TCP, and UDP protocols.
• Actors (Durable Objects): Run long-lived, stateful tasks with persistence, hibernation, and real-time capabilities—ideal for AI agents, real-time applications, and local-first sync scenarios.
• Containers: Execute CPU- and memory-intensive workloads in secure containers with fast cold starts and rapid scaling, supporting batch jobs, code sandboxes, and game servers.
• No Arbitrary Timeouts: Run long-running processes without worrying about forced timeouts, a common limitation in traditional serverless platforms.
• Global Low Latency: Deploy applications close to users or data centers for optimal performance, ensuring instant response times and zero cold starts.
• Intelligent Scaling: Automatically handle any load without manual intervention, minimizing idle CPU time and optimizing costs for real-time and long-running applications.
• Comprehensive Monitoring: Gain real-time visibility and control over your infrastructure with built-in monitoring, log querying, and safe deployment workflows.
• Flexible Deployment Models: Choose between fully-managed Rivet Cloud, bring-your-own-cloud, or self-hosted open-source deployments to fit your organization’s needs.
• Developer Collaboration: Collaborate securely with teammates, test changes in isolated environments, and manage resources with a powerful tagging system.

Rivet stands out by removing the traditional constraints of serverless platforms, such as cold starts, proprietary runtimes, and limited protocol support. Its open-source nature ensures transparency and flexibility, while its robust feature set empowers developers to build, deploy, and scale modern applications with confidence. Whether you’re building AI agents, real-time systems, or complex backends, Rivet provides the tools and infrastructure to support your vision, all while maintaining control over your deployment and scaling strategies.
