What is Dapr?
Nine days after 1.19 GA, Dapr patches 11 security flaws across three release lines.
Dapr 1.19.1, 1.18.10 and 1.17.19 landed together on Oct 31 with the same 11 security fixes. They cover access control bypasses in service invocation, an API token check bypass, Scheduler reminders delivered to the wrong app, unauthenticated metadata writes on the public port, and forged outbox messages. 1.19 itself reached GA on Oct 22 with up to 40% more workflow throughput, cross-app workflow control and a Dapr MCP server.
What is Rivet?
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
Dapr vs Rivet: editorial side-by-side
Dapr
6.3DEVOPS
Nine days after 1.19 GA, Dapr patches 11 security flaws across three release lines.
◆ Current state
Dapr 1.19.1, 1.18.10 and 1.17.19 landed together on Oct 31 with the same 11 security fixes. They cover access control bypasses in service invocation, an API token check bypass, Scheduler reminders delivered to the wrong app, unauthenticated metadata writes on the public port, and forged outbox messages. 1.19 itself reached GA on Oct 22 with up to 40% more workflow throughput, cross-app workflow control and a Dapr MCP server.
◆ Where it's heading
The 1.19 feature push is now followed by a hardening pass on trust between apps, sidecars and control plane services. Several fixes tighten boundaries inside a namespace, which matters more as cross-app workflows make those boundaries central. Older lines are still patched in parallel, and the percent-encoding fix extends one first shipped in 1.17.16 and 1.18.6.
◆ Prediction
Expect further 1.19.x patches, since this batch completes an earlier incomplete fix and more of the same class may surface. The entries give no timing for 1.20.
Rivet
7.5DEVOPS
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
◆ Current state
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
◆ Where it's heading
Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.
◆ Prediction
Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
