Apache JMeter vs Artillery

Apache JMeter is a free, open-source Java application for testing functional behavior under load and measuring performance. It can simulate heavy workloads on servers, networks and other systems. Supported test types include HTTP and HTTPS, SOAP and REST, FTP, JDBC, LDAP, JMS, email protocols, TCP, Java objects, and native commands or shell scripts. Its test IDE can record plans from browsers or native applications, then help users build and debug them. JMeter provides command-line operation on Java-compatible systems and can generate dynamic HTML reports. It also supports remote testing, pluggable samplers and timers, scripting such as Groovy and BeanShell, and plugins for analysis and visualization. Third-party open-source libraries connect it to Maven, Gradle and Jenkins for continuous integration. JMeter works at the protocol level: it does not execute JavaScript in pages or render them as a browser does. It requires Java 8 or later. The project recommends command-line rather than GUI operation for load testing and advises caution with untrusted JMX files, which may execute code when opened.

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.
