What is Rivet?
Rivet's Rust SDK for Actors is generally available.
Rivet has spent two months building 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. The Rust SDK for Rivet Actors is now generally available, with SQLite, WebSockets, cron and OpenTelemetry built in.
What is WildFly?
WildFly 42 brings virtual threads to Jakarta Concurrency.
WildFly is a Jakarta EE application server on a regular train of Beta, Final and patch releases. WildFly 42.0.0.Final (October 22) supports virtual threads in the Jakarta Concurrency 3.1 implementation, promotes idle time-based eviction for distributable sessions, SFSBs and timers to default stability, and adds automatic meter management for resources added at runtime. 41.0.1 in August was a security patch closing three IIOP CVEs.
Rivet vs WildFly: editorial side-by-side
Rivet
6.3DEVOPS
Rivet's Rust SDK for Actors is generally available.
◆ Current state
Rivet has spent two months building 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. The Rust SDK for Rivet Actors is now generally available, with SQLite, WebSockets, cron and OpenTelemetry built in.
◆ Where it's heading
Rivet is widening who can build on its actor model while 3.0 matures: a Rust SDK GA lets performance-sensitive teams use it without a TypeScript layer. The platform direction remains S3-only infrastructure for stateful workloads.
◆ Prediction
Expect 3.0 to move toward a stable release and more SDK languages. The entries don't show a 3.0 GA date.
WildFly
5.0DEVOPS
WildFly 42 brings virtual threads to Jakarta Concurrency.
◆ Current state
WildFly is a Jakarta EE application server on a regular train of Beta, Final and patch releases. WildFly 42.0.0.Final (October 22) supports virtual threads in the Jakarta Concurrency 3.1 implementation, promotes idle time-based eviction for distributable sessions, SFSBs and timers to default stability, and adds automatic meter management for resources added at runtime. 41.0.1 in August was a security patch closing three IIOP CVEs.
◆ Where it's heading
WildFly moves features through stability levels release by release; 42 promotes the eviction configuration that first arrived in 39. The bug list also shows continuing cleanup of XML parsing issues (CWE-611) and clustering edge cases.
◆ Prediction
Expect 42.0.1.Final next, consolidating fixes and component upgrades as 41.0.1 did.
