What is Dapr?
Dapr 1.19 ships cross-app workflows, an MCP server and 40% faster workflow throughput.
Dapr 1.19 reached GA on Oct 22 after seven release candidates. It raises workflow throughput by up to 40%, lets one app control workflows owned by another under access policies, and adds alpha Binary Store, Search and Vector building blocks plus a Dapr MCP server. In the same week, 1.16 through 1.18 received patches for an Operator scoping leak, compromised eMudhra intermediates and Redis Entra ID token expiry.
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.
Dapr vs Rivet: editorial side-by-side
Dapr
6.3DEVOPS
Dapr 1.19 ships cross-app workflows, an MCP server and 40% faster workflow throughput.
◆ Current state
Dapr 1.19 reached GA on Oct 22 after seven release candidates. It raises workflow throughput by up to 40%, lets one app control workflows owned by another under access policies, and adds alpha Binary Store, Search and Vector building blocks plus a Dapr MCP server. In the same week, 1.16 through 1.18 received patches for an Operator scoping leak, compromised eMudhra intermediates and Redis Entra ID token expiry.
◆ Where it's heading
Dapr is pushing workflows to the centre of the runtime: faster engines, cross-app control and policy rules that gate scheduling on upstream events. New building blocks for files, search and vectors, along with the MCP server, point at AI-agent and data-heavy workloads. Several older lines are still patched in parallel, especially for security.
◆ Prediction
Expect 1.19.x patches soon, given the behaviour changes flagged in SDKs, and more components for the alpha Search and Vector blocks beyond Meilisearch.
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.
