What is Flux?

At ten years old, Flux turns its CLI into a plugin platform and ships schema validation on top

Flux is a mature GitOps continuous-delivery project for Kubernetes, and its most recent releases mark an architectural inflection: version 2.9 introduced a CLI plugin system, and the first flagship plugin—Flux Schema, with a hosted Ecosystem Schema Catalog—arrived weeks later. The feed is blog-sourced, so genuine releases sit alongside a 10-year anniversary post and enterprise case studies.

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.

At ten years old, Flux turns its CLI into a plugin platform and ships schema validation on top

◆ Current state

Flux is a mature GitOps continuous-delivery project for Kubernetes, and its most recent releases mark an architectural inflection: version 2.9 introduced a CLI plugin system, and the first flagship plugin—Flux Schema, with a hosted Ecosystem Schema Catalog—arrived weeks later. The feed is blog-sourced, so genuine releases sit alongside a 10-year anniversary post and enterprise case studies.

◆ Where it's heading

Flux is evolving from a fixed CD toolset into an extensible platform. The plugin system opens the CLI to first-class extensions, and the schema catalog's LLM-optimized indexes signal an eye toward AI-assisted manifest authoring and validation. The trajectory points to an ecosystem play: more official and community plugins layered on the new extension surface.

◆ Prediction

Expect additional plugins built on the 2.9 system and continued growth of the Ecosystem Schema Catalog, likely with tighter integration into AI-assisted Kubernetes tooling.

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.
