What is containerd?
containerd 2.4.0-rc.0 removes checkpoint-restore-via-CreateContainer and flips user-namespace networking on by default
containerd is in active parallel-maintenance mode across four branches (1.7, 2.0, 2.2, 2.3 LTS, 2.4 dev). The September 4 patch wave addressed CVE-2026-53495 across all active branches — stripping sensitive auth headers when fetching descriptor image URLs. The 2.3 LTS branch continues to absorb fixes at a steady pace: startup hang prevention, EROFS layer-stack reliability, Windows compatibility improvements, and a runc upgrade to v1.5.1.
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.

containerd 2.4.0-rc.0 removes checkpoint-restore-via-CreateContainer and flips user-namespace networking on by default
◆ Current state
containerd is in active parallel-maintenance mode across four branches (1.7, 2.0, 2.2, 2.3 LTS, 2.4 dev). The September 4 patch wave addressed CVE-2026-53495 across all active branches — stripping sensitive auth headers when fetching descriptor image URLs. The 2.3 LTS branch continues to absorb fixes at a steady pace: startup hang prevention, EROFS layer-stack reliability, Windows compatibility improvements, and a runc upgrade to v1.5.1.
◆ Where it's heading
Development is converging on the 2.4 release, the first non-LTS cycle after 2.3. The 2.4 RC removes the deprecated checkpoint-restore-via-CreateContainer codepath (disabled by default in 2.2/2.3, now gone entirely), enables user-namespace host-network by default, and expands EROFS warm-cache support. The new UpdateSandbox RPC and the MountCapabilities bootstrap extension replacing the old `runtime-allow-mounts` shim annotation reflect containerd pushing a tighter, more auditable shim API contract.
◆ Prediction
2.4.0 stable will likely ship within a few weeks given the RC0 is tagged. The auth-header-stripping pattern applied across all branches in the CVE patch suggests a follow-on audit of remaining registry interaction surfaces is possible.
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.
