Artillery Alternative — JMeter + k6 in the Cloud

What is Artillery?

Artillery is an open-source load testing tool written in Node.js. Tests are defined in YAML (or JavaScript for advanced scenarios) and Artillery executes HTTP, WebSocket, Socket.io, and other protocols. The OSS version runs from one machine; Artillery also offers a paid "Artillery Pro" cloud product for distributed execution.

Artillery is well-suited to Node.js-fluent teams who want declarative test definitions. The OSS version is easy to get started with — install via npm, write a YAML file, run from the command line. Distributed/cloud execution requires either Artillery Pro or self-managed AWS Fargate orchestration.

When Artillery is the right tool

Artillery fits these workflows:

• Node.js teams. Engineering teams already invested in Node.js find Artillery's npm install + JavaScript scenarios natural.
• Declarative YAML test config. Simple HTTP load tests can be expressed in a few lines of YAML — fast to write and easy to PR-review.
• WebSocket and Socket.io load testing. Artillery has first-class support for protocols beyond plain HTTP, including realtime connections.
• Local CI runs. Wrap Artillery in a CI step for quick smoke load tests against staging environments.

Where Artillery stops being enough

The OSS Artillery model is excellent for single-machine quick tests. Once you need scale, distribution, or platform consolidation, gaps appear:

• Distributed execution requires Artillery Pro or self-managed AWS Fargate. The OSS tool runs from one machine. Beyond a few thousand VUs, you need a paid product or to manage cloud orchestration yourself.
• No persistent UI dashboard. The OSS tool prints results to terminal. Historical comparison requires custom data store.
• No native multi-region execution. Artillery Pro adds cloud regions; OSS Artillery runs wherever you launch it.
• JMeter and k6 scripts don't run on Artillery. Artillery uses its own YAML/JS format.
• No native page speed or API monitoring. Artillery is purely load testing. Continuous monitoring needs separate tools.

LoadFocus vs Artillery — feature comparison

The table below compares LoadFocus against Artillery (OSS + Pro). Pricing accurate as of April 2026.

When LoadFocus is the right upgrade from Artillery

The decision usually comes down to script-format preference, platform consolidation, or pricing transparency.

You want JMeter or k6 as the script format

Artillery uses its own YAML/JS format. JMeter and k6 are both more widely adopted across the industry. LoadFocus runs JMeter and k6 natively; switching to those formats opens broader tooling and skill-pool options.

You need distributed execution without paying for Artillery Pro

OSS Artillery runs from one machine. Artillery Pro adds cloud distribution but pricing is sales-quoted. LoadFocus offers transparent SaaS pricing starting at $29/month.

You want consolidated load + page speed + API monitoring

Artillery is load-only. LoadFocus combines all three on one platform.

You want persistent test history without DIY dashboards

Artillery OSS prints to terminal. LoadFocus stores test history with built-in trend graphs and regression diffs.

You want a free tier with no credit card

LoadFocus offers a no-credit-card free tier. Artillery Pro requires sales engagement for evaluation.

WebSocket testing note

Artillery has first-class WebSocket and Socket.io support. LoadFocus's primary script formats (JMeter, k6) support WebSocket but require more script-level work. If realtime protocol load testing is your primary use case, Artillery may remain the better fit; for general HTTP load + page speed + API monitoring, LoadFocus consolidates more on one platform.

Migration from Artillery

1. Sign up at loadfocus.com/signup.
2. Translate your Artillery YAML scenarios to k6 JavaScript. The mapping is direct: Artillery's YAML "flow" with HTTP requests maps to k6's http.get/post calls in a default function.
3. Upload the .js script to LoadFocus.
4. Configure VU count and ramp-up to match your Artillery scenario phases.
5. Run from one or more regions. Compare results against your Artillery runs to validate.

FAQ: LoadFocus vs Artillery

Can LoadFocus run my Artillery YAML scripts?

No. Artillery's YAML format is specific to Artillery. The closest LoadFocus equivalent is k6 (JavaScript), which provides similar declarative request flows.

Is LoadFocus more expensive than OSS Artillery?

OSS Artillery is free (open-source); LoadFocus starts at $29/month. The fair comparison is OSS Artillery vs LoadFocus only when you've factored the operational cost of running Artillery at scale (Fargate setup, monitoring, etc.).

Should I use Artillery Pro or LoadFocus?

Both are managed cloud load testing platforms. Artillery Pro is best when you want Artillery's specific YAML/JS format and WebSocket strengths. LoadFocus is best when you want JMeter or k6 scripts, transparent pricing, and consolidated load + page speed + API monitoring.

Can I use both tools?

Yes. Many teams use Artillery for WebSocket-specific load tests and LoadFocus for HTTP/API load + page speed + API monitoring.

Does LoadFocus support YAML test definitions?

LoadFocus's primary test definitions are via web UI and JMeter/k6 scripts (not YAML). For YAML-driven load testing, Artillery's model is more native.
