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 Linkerd?
Linkerd pairs post-quantum mTLS with steady mesh perf work, on a blog-as-changelog feed.
Linkerd, the CNCF-graduated Rust service mesh, tracks its project blog rather than a pure release feed — so genuine version announcements (2.19, 2.20) sit alongside community deep-dives and republished educational essays. The product itself is in a mature, security-forward phase: 2.19 shipped post-quantum mTLS by default, and 2.20 follows with rate-limit-aware load balancing, lower memory use, and better inbound metrics. Native sidecars graduated to beta over this stretch.

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.
Linkerd
2.5DEVOPS
Linkerd pairs post-quantum mTLS with steady mesh perf work, on a blog-as-changelog feed.
◆ Current state
Linkerd, the CNCF-graduated Rust service mesh, tracks its project blog rather than a pure release feed — so genuine version announcements (2.19, 2.20) sit alongside community deep-dives and republished educational essays. The product itself is in a mature, security-forward phase: 2.19 shipped post-quantum mTLS by default, and 2.20 follows with rate-limit-aware load balancing, lower memory use, and better inbound metrics. Native sidecars graduated to beta over this stretch.
◆ Where it's heading
Two arcs run in parallel. The product is doubling down on operational simplicity and secure defaults — post-quantum crypto, native-sidecar maturation, OpenTelemetry consolidation (dropping the jaeger extension and OpenCensus), and steady proxy memory and metrics work across edge releases. The blog is simultaneously being used to seed community education (protocol detection, destination internals, certificate rotation), pointing to an adoption-and-retention push alongside the engineering cadence.
◆ Prediction
Expect the weekly edge-release train to keep feeding the next stable after 2.20, with more memory/metrics hardening and native-sidecar and Gateway API work. The crawled feed will keep interleaving real announcements with educational posts, so signal will stay mixed.
