What is Artillery?

Artillery adds a single-request diagnostic command and finally makes ESM a first-class citizen.

Artillery ships a patch release every four to eight weeks, and for most of the last ten that release was a Playwright version bump plus fixes to the distributed runners on Lambda, Fargate and Azure ACI. The recurring failure mode being chased is dependency resolution in worker environments: tests that need external npm modules silently starting with fewer VUs, skipped installs, module-not-found errors at run time. v2.0.34 breaks that pattern with genuine new surface area.

What is NATS?

NATS second release candidates add a config reload check and faster redelivery queues.

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

Artillery vs NATS: editorial side-by-side

A
Artillery
DEVOPS
3.8

Artillery adds a single-request diagnostic command and finally makes ESM a first-class citizen.

◆ Current state

Artillery ships a patch release every four to eight weeks, and for most of the last ten that release was a Playwright version bump plus fixes to the distributed runners on Lambda, Fargate and Azure ACI. The recurring failure mode being chased is dependency resolution in worker environments: tests that need external npm modules silently starting with fewer VUs, skipped installs, module-not-found errors at run time. v2.0.34 breaks that pattern with genuine new surface area.

◆ Where it's heading

Two arcs are converging. The first is reliability of the cloud runners, addressed incrementally by bundling more into the worker image rather than fetching at test startup — the fake-data plugin moved in this release, following the pre-packaged Playwright and CLI binaries earlier in the window. The second is modern JavaScript support: full ESM across processors, plugins, engines and reporters, plus TypeScript definitions that now model the entire test script rather than a fragment. Together they point at a team removing the reasons a test fails for reasons unrelated to the system under test.

◆ Prediction

Expect the ping command to grow assertion and output options, and the worker images to keep absorbing commonly-used plugins so that startup installs disappear entirely.

N
NATS
DEVOPS
5.0

NATS second release candidates add a config reload check and faster redelivery queues.

◆ Current state

NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

◆ Where it's heading

The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.

◆ Prediction

Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
