Artillery vs Vegeta

Artillery combines load testing, scalable Playwright end-to-end testing, and production monitoring in one toolkit. It supports load, stress, and soak tests, including distributed runs across AWS Lambda, AWS Fargate, and Azure Container Instances. HTTP, WebSocket, and Socket.IO are built in, with other protocols available through plugins. Playwright scripts can run as load tests or synthetic checks; the homepage also describes a Turbo runner beta for splitting large Playwright suites into parallel work. Listed integrations include Datadog, OpenTelemetry, New Relic, Splunk, Honeycomb, AWS CloudWatch, GitHub Actions, GitLab CI/CD, Jenkins, CircleCI, and Azure DevOps. Artillery says its typical users include application developers, test and QA engineers, and operations or SRE teams responsible for production backend systems. Cloud reporting is opt-in per test run, while tests run in the user's own environment even when reports are sent to Artillery Cloud. The Free plan lists 30 reports per month; Team costs $199 a month and includes 1,000 reports per month. Continued overages may degrade service or lead to read-only mode.

Vegeta is a free, open-source HTTP load-testing tool and Go library that sends requests at a constant rate. Its command-line interface is built for UNIX-style composition, while the library offers use from Go programs. The project states that its load measurements avoid coordinated omission and that distributed testing is supported. Reports can be written as text, JSON, histograms, or HDR plots, and results can also be encoded as CSV, Gob, or JSON. The attack command can expose an optional Prometheus exporter. HTTP/2 works when supported by the server, including HTTP/2 over TCP without TLS. TLS options include client certificates and keys, custom root certificates, and ignoring invalid server certificates. The documented request timeout defaults to 30 seconds, with zero disabling timeouts. Prebuilt binaries, package-manager installs, distribution packages, and source builds are documented for Linux, macOS, Windows, API use, and self-hosting. The repository uses the MIT license.
