What is Prefect?
Prefect spent the quarter on the surfaces operators actually touch: UI, search, and now artifacts
Prefect's recent releases are dominated by interface and operability work rather than the orchestration core. The redesigned UI became the default for self-hosted servers in 3.8, Cloud picked up workspace-wide search and a command palette, and artifacts now have a top-level home with support for every SDK artifact type.
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.

◆ Current state
Prefect's recent releases are dominated by interface and operability work rather than the orchestration core. The redesigned UI became the default for self-hosted servers in 3.8, Cloud picked up workspace-wide search and a command palette, and artifacts now have a top-level home with support for every SDK artifact type.
◆ Where it's heading
The engine work landed earlier — the real-time server-to-worker channel and a faster scheduler across the 3.7.x line — and attention has since moved up the stack to navigation and visibility. Each release makes an existing object easier to find rather than adding a new one.
◆ Prediction
Expect the artifact surface to grow comparison or lineage views that connect it to the Assets tracking introduced last year, since both describe what a workflow produces.
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.
