What is Rivet?
Rivet is graduating from an actor library into a managed serverless platform.
Rivet ships at a rapid clip around its actor model: a managed serverless hosting product (Rivet Compute), new first-class SDKs (Rust, Effect) on top of the existing TypeScript surface, and a native Rust rewrite of its core (Rivet 2.3, RivetKit). Earlier work, agentOS and per-actor SQLite/queues/workflows, points the actor primitive squarely at AI-agent and durable-execution use cases.
What is Kubernetes?
Kubernetes is rebuilding its core scheduling and hardware model around AI workloads.
Kubernetes is mid-pivot from a general container orchestrator toward the default substrate for AI/ML and batch compute. Recent releases center on hardware-aware scheduling — Dynamic Resource Allocation reached GA, and workload-aware gang scheduling with a new PodGroup API landed in v1.36 — alongside storage features tuned for stateful and AI pipelines. Operational and security hardening (PSI metrics GA, CVE record corrections, externalIPs deprecation) round out the cadence.
Rivet vs Kubernetes: editorial side-by-side
Rivet
6.3DEVOPS
Rivet is graduating from an actor library into a managed serverless platform.
◆ Current state
Rivet ships at a rapid clip around its actor model: a managed serverless hosting product (Rivet Compute), new first-class SDKs (Rust, Effect) on top of the existing TypeScript surface, and a native Rust rewrite of its core (Rivet 2.3, RivetKit). Earlier work, agentOS and per-actor SQLite/queues/workflows, points the actor primitive squarely at AI-agent and durable-execution use cases.
◆ Where it's heading
The product is moving up the stack from a self-hosted library toward an opinionated platform: own the runtime (Rust rewrites), broaden the language surface (Rust and Effect SDKs), and capture deployment with single-command managed hosting. agentOS signals the target workload is AI agents needing cheap, fast-cold-start isolation.
◆ Prediction
Expect the Compute platform to deepen, billing, autoscaling, and regions, and more SDKs or agent-oriented primitives that make Rivet the default place to run actor-based agent backends.
Kubernetes
5.0DEVOPSINFRA · APIS
Kubernetes is rebuilding its core scheduling and hardware model around AI workloads.
◆ Current state
Kubernetes is mid-pivot from a general container orchestrator toward the default substrate for AI/ML and batch compute. Recent releases center on hardware-aware scheduling — Dynamic Resource Allocation reached GA, and workload-aware gang scheduling with a new PodGroup API landed in v1.36 — alongside storage features tuned for stateful and AI pipelines. Operational and security hardening (PSI metrics GA, CVE record corrections, externalIPs deprecation) round out the cadence.
◆ Where it's heading
The center of gravity is GPU/accelerator scheduling and multi-node batch workloads. Expect the Workload/PodGroup APIs to mature from alpha toward beta, DRA's ecosystem of drivers and tooling to thicken, and storage work (Volume Health, COSI) to follow AI data-gravity needs. The security posture is shifting from patch-everything toward documenting and mitigating architectural risk.
◆ Prediction
Next releases will likely promote the workload-aware scheduling APIs past alpha and expand DRA device-failure handling, with etcd 3.7 moving from beta to a final release that removes the last v2store dependencies.
