Artillery is an open source load testing and performance testing platform for APIs, microservices, and web applications. Built with Node.js and available as an npm package, Artillery supports HTTP/1, HTTP/2, WebSocket, Socket.IO, gRPC, and custom protocols through plugins. It includes a YAML-based test scenario definition language, a plugin ecosystem for extending functionality, and Artillery Cloud for distributed load testing, CI/CD integration, and centralized reporting. Artillery is used by developers, QA engineers, and SREs to run load tests, performance benchmarks, Playwright-based synthetic monitoring, and end-to-end tests at scale. The project is licensed under MPL-2.0 and maintained by Artilleryio.
Artillery publishes 1 API on the APIs.io network. Tagged areas include Load Testing, Performance Testing, Open-Source, Testing, and DevOps.
Artillery’s developer surface includes engineering blog, developer portal, documentation, changelog, pricing, API reference, getting-started guide, and 33 more developer resources.
Open Source Surface applies to this provider. This product is open source and we
read its repository directly, so Open Source Surface carries
10 points of the composite. It is scored from what the repository actually
publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the
provider rather than inferred from our own catalog pointers.
This facet adds; nothing was taken away to make room for it. An open-source project is not excused from
the commercial facets, because exemption would strip it of the points it does earn.
If we have the wrong repository, or this product is not open source, say so on your
provider repo and we
will drop the facet rather than have you publish against it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 90 points between them,
because the conditional facet above carries the other
10. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 90% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/artillery: open an issue to ask a question, or submit a pull request to add artifacts.

Artillery Cloud is the hosted platform behind the open source Artillery CLI: it runs distributed load and Playwright E2E tests at scale across AWS Lambda, AWS Fargate and Azure ...
Load test HTTP/1 and HTTP/2 REST APIs, GraphQL endpoints, and web applications with configurable virtual users, arrival rates, and scenario definitions.
WebSocket and Socket.IO Testing
Test real-time applications with WebSocket and Socket.IO protocol support, enabling load testing of chat, notifications, and streaming applications.
Playwright Integration
Run Playwright browser-based end-to-end scenarios under load, enabling realistic user simulation and synthetic monitoring from the same test framework.
Plugin Ecosystem
Extensible plugin system with official plugins for gRPC, Kafka, AWS Lambda, Kinesis, and community plugins for many other protocols.
Artillery Cloud
Hosted cloud platform for running distributed load tests at massive scale across multiple cloud regions, with centralized results and team collaboration features.
YAML Test Scenarios
Human-readable YAML test scenario definitions supporting think time, loops, conditional logic, data CSV files, and custom JavaScript functions.
Backend developers and QA engineers run load tests against REST and GraphQL APIs to identify performance bottlenecks and ensure stability under expected traffic volumes.
CI/CD Performance Gates
Engineering teams integrate Artillery into CI/CD pipelines to run performance tests on every pull request, failing builds that exceed latency or error rate thresholds.
Synthetic Monitoring
SREs use Artillery with Playwright to run synthetic monitors that continuously validate critical user journeys from multiple cloud regions.
Pre-Launch Stress Testing
Product teams run stress tests before major launches or sales events to identify the maximum capacity of their infrastructure.
