What is Rivet?
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
What is Svelte?
SvelteKit 3 reached its Release Candidate with the migration tooling already in the box.
Svelte 5 core is in steady quality-of-life mode — 5.57 added SvelteMap.getOrInsert and getOrInsertComputed, a has check on createContext, select defaultValue, and exported render-output types. All the directional work sits in SvelteKit 3, which reached a Release Candidate this month after roughly twenty-five @next prereleases. The sv CLI has been reworked around the upgrade: a task-based sveltekit-3 migration bumps dependencies and rewrites $lib to #lib, and newly created projects already default to #lib.
Rivet vs Svelte: editorial side-by-side
Rivet
7.5DEVOPS
Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.
◆ Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆ Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆ Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.
Svelte
5.0DEVOPS
SvelteKit 3 reached its Release Candidate with the migration tooling already in the box.
◆ Current state
Svelte 5 core is in steady quality-of-life mode — 5.57 added SvelteMap.getOrInsert and getOrInsertComputed, a has check on createContext, select defaultValue, and exported render-output types. All the directional work sits in SvelteKit 3, which reached a Release Candidate this month after roughly twenty-five @next prereleases. The sv CLI has been reworked around the upgrade: a task-based sveltekit-3 migration bumps dependencies and rewrites $lib to #lib, and newly created projects already default to #lib.
◆ Where it's heading
Kit 3 is arriving as a consolidation rather than a rewrite, and the breaking changes stay narrow and mechanical — defineParams moving to @sveltejs/kit/params, cross-page form actions matching native form behavior, adapter Vite plugins split into pre and post groups. The team is running both lines at once: Kit 3 docs live on next.svelte.dev while 2.x still takes patch releases, which is what a low-risk major looks like in practice. Tooling for agent-assisted upgrades is being folded into the same effort, with the mcp add-on replaced by a broader ai-tools add-on covering MCP servers, skills, and sub-agents per client, and sv migrate now emitting a list of leftover changes for a developer or agent to resolve.
◆ Prediction
Expect SvelteKit 3.0 stable within the next digest or two, with remaining @next churn confined to adapter and routing internals.
