What is Argo CD?
Argo CD's 3.5 line is in release-candidate hardening after a feature-heavy rc1 (Helm 4, supply-chain, Gateway API).
Argo CD shipped 3.4.0 to GA and has moved the 3.5 line into release candidates. The 3.5.0-rc1 carried a large feature set: Helm 3-to-4 migration, opt-in source-integrity verification for the hydrator, Gateway API support in the network view, mTLS in the repo-server, server-operation impersonation, and ApplicationSet UI work, while rc2 is bug-fix stabilization. The project keeps a strong supply-chain posture with cosign-signed images and SLSA Level 3 provenance.
What is Rivet?
Rivet is repositioning its actor platform as the cheap runtime layer for coding agents.
Rivet is shipping at a high cadence and pivoting its narrative toward AI-agent infrastructure. The recent window includes agentOS v0.2 (a WebAssembly-powered, low-cost alternative to sandboxes for running coding agents), Rivet Compute (serverless hosting for actors), a Rust rewrite of Secure Exec, and new Rust and Effect SDKs for Rivet Actors. The pitch is that agents need a lightweight Linux VM, not a heavy sandbox.
Argo CD vs Rivet: editorial side-by-side
Argo CD
6.3DEVOPS
Argo CD's 3.5 line is in release-candidate hardening after a feature-heavy rc1 (Helm 4, supply-chain, Gateway API).
◆ Current state
Argo CD shipped 3.4.0 to GA and has moved the 3.5 line into release candidates. The 3.5.0-rc1 carried a large feature set: Helm 3-to-4 migration, opt-in source-integrity verification for the hydrator, Gateway API support in the network view, mTLS in the repo-server, server-operation impersonation, and ApplicationSet UI work, while rc2 is bug-fix stabilization. The project keeps a strong supply-chain posture with cosign-signed images and SLSA Level 3 provenance.
◆ Where it's heading
Argo CD is converging 3.5 toward GA, so expect further rc bug-fix rounds until it stabilizes. The 3.5 theme blends supply-chain security (source integrity, provenance, mTLS), ecosystem currency (Helm 4, Gateway API), and ApplicationSet and UI maturation. After GA, the rolling stable tag advances and the 3.4 line drops to maintenance cherry-picks.
◆ Prediction
Expect one or more further 3.5.0 release candidates with bug-fix cherry-picks, then a 3.5.0 GA that moves the rolling stable tag forward.
Rivet
7.5DEVOPS
Rivet is repositioning its actor platform as the cheap runtime layer for coding agents.
◆ Current state
Rivet is shipping at a high cadence and pivoting its narrative toward AI-agent infrastructure. The recent window includes agentOS v0.2 (a WebAssembly-powered, low-cost alternative to sandboxes for running coding agents), Rivet Compute (serverless hosting for actors), a Rust rewrite of Secure Exec, and new Rust and Effect SDKs for Rivet Actors. The pitch is that agents need a lightweight Linux VM, not a heavy sandbox.
◆ Where it's heading
Rivet is layering an agent-runtime stack on top of its actor/edge-compute core: agentOS provides isolated, fast-booting environments for coding agents at a fraction of sandbox cost, Rivet Compute removes infra management, and the multiplying SDKs (Rust, Effect, earlier SQLite) widen language and framework reach. The strategic bet is to become the default execution substrate for coding agents by undercutting incumbent sandboxes on cost and cold-start.
◆ Prediction
Expect agentOS to keep hardening (more language runtimes, orchestration features) and Rivet to push the cost-versus-sandbox comparison as its primary wedge, likely with managed-platform and pricing milestones next.
