What is NATS?
NATS 2.15 replaces JetStream's assignment engine with a desired-state metalayer — the biggest architectural move in the project's recent history.
NATS is running dual-track releases: the 2.14.x line is receiving steady reliability work (consumer race conditions, filestore correctness, Raft edge cases), while 2.15.0 has entered the RC stage. The 2.14.6 and 2.14.7 release candidates collectively address more than a dozen concurrency and persistence defects accumulated in the messaging and storage layers. The jump from 2.12 to 2.14 — skipping 2.13 entirely — has been followed by an unusually dense sequence of point releases.
What is Rivet?
Rivet positions its Actors runtime as the infrastructure layer for enterprise-ready, AI-native application deployment.
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.
NATS vs Rivet: editorial side-by-side
NATS
7.5DEVOPS
NATS 2.15 replaces JetStream's assignment engine with a desired-state metalayer — the biggest architectural move in the project's recent history.
◆ Current state
NATS is running dual-track releases: the 2.14.x line is receiving steady reliability work (consumer race conditions, filestore correctness, Raft edge cases), while 2.15.0 has entered the RC stage. The 2.14.6 and 2.14.7 release candidates collectively address more than a dozen concurrency and persistence defects accumulated in the messaging and storage layers. The jump from 2.12 to 2.14 — skipping 2.13 entirely — has been followed by an unusually dense sequence of point releases.
◆ Where it's heading
The 2.15 desired-state metalayer is NATS's most consequential JetStream architecture change in years. It replaces reactive assignment logic with a reconciliation model — the same design philosophy that made Kubernetes reliable at scale. Immediate practical payoffs: stream moves can be cancelled mid-flight, nodes can be evacuated cleanly during maintenance, and disaster recovery no longer requires manual cluster intervention. v2.15.0-RC.1 is the inflection point; the 2.14.x work feeds directly into a stable foundation for it.
◆ Prediction
v2.15.0 stable should ship within weeks given the RC trajectory. The new 1000-consumer-per-stream default limit introduced in 2.15 will require existing deployments to audit their stream configs before upgrading — that migration story will define how smoothly adoption goes.
Rivet
8.8DEVOPS
Rivet positions its Actors runtime as the infrastructure layer for enterprise-ready, AI-native application deployment.
◆ Current state
Rivet has shipped three substantive capability moves in rapid succession: BYOC (Bring Your Own Cloud, letting enterprises run Rivet's control plane inside their own AWS or GCP VPCs), MCP integration (exposing Rivet Actors as a first-class tool in Claude Code, Cursor, Codex, and Gemini CLI), and Dynamic Apps (a V8-isolate-based runtime for deploying AI-generated applications for end users). Underneath all of this is the Actors model — a durable, stateful compute primitive built on open-source infrastructure. Durable Streams, a zero-disk SQLite storage engine with S3 tiering, and the agentOS execution API round out the technical foundation.
◆ Where it's heading
Rivet is building toward a single answer to a specific question: where does agent-generated, user-facing software actually run? The BYOC move unlocks regulated industries and large enterprises who can't send data to a SaaS control plane. MCP turns Rivet's Actors into something any AI client can discover and call without bespoke integration. Dynamic Apps makes Rivet the runtime, not just the infrastructure, for user-generated software. The through-line is that Rivet wants every AI agent — whether built by a developer or generated at runtime — to run on the Actors primitive with Rivet managing the lifecycle.
◆ Prediction
BYOC on AWS/GCP is the foundation; Azure support and SOC 2 certification are the logical next steps to close enterprise deals. Expect MCP to expand to more clients (OpenAI Codex, Copilot, Windsurf) as the MCP ecosystem grows, and Dynamic Apps to get versioning and rollback — the missing piece for user-facing production deployments.
