  • Open-Source
    The tool offers an open-source version, allowing for cost-effective testing solutions and community-driven support and enhancements.

Possible disadvantages of gatling.io

  • Learning Curve
    The use of Scala in writing scripts may pose a steep learning curve for users unfamiliar with this programming language.
  • Limited Protocol Support
    Gatling primarily focuses on HTTP protocols, which may limit its use for applications that require broad protocol support.
  • Resource Intensive
    Running high-load tests can be resource-intensive, requiring considerable hardware infrastructure for accurate simulations.
  • Complex Setup
    Setting up distributed testing or integrating with other systems may require additional configuration and technical expertise, adding to the initial setup complexity.
  • Paid Enterprise Version
    Advanced features and support are available in the enterprise version, which may incur additional costs compared to the open-source offering.

Loader.io features and specs

  • Ease of Use
    Loader.io offers a straightforward and intuitive user interface, making it easy for users to set up and run load tests without a steep learning curve.
  • Quick Test Setup
    With Loader.io, you can quickly set up load tests by simply verifying your website, inputting the target URL, and defining parameters such as duration and the number of clients.
  • Scalability
    Loader.io allows you to scale your tests from a few clients to hundreds of thousands, accommodating different testing needs.
  • Free Tier
    Loader.io offers a free tier that allows users to perform basic load testing, which is great for small projects or initial testing phases.
  • Integration
    Loader.io integrates well with other services and CI/CD pipelines, enabling automated performance testing as part of your development workflow.

Possible disadvantages of Loader.io

  • Limited Test Duration
    The free tier and some lower-tier plans have limitations on the duration of load tests, which might not be sufficient for testing long-running processes.
  • Complex Scenarios
    Loader.io may not support highly complex testing scenarios out-of-the-box, such as tests requiring advanced scripting or multi-step transactions.
  • Resource Limitations
    High concurrency and load levels may require higher-tier plans, which can become costly for larger-scale testing.
  • Geographic Limitations
    There may be limitations on the geographical distribution of clients, which could affect tests intended to simulate traffic from varied regions.
  • Reporting
    While Loader.io provides basic reporting, it may lack the depth and customization options offered by some other performance testing tools, such as detailed analytics and advanced visualization features.

  • express server failing after high number of requests in digital ocean droplet with high configuration
    I wanted to see how many requests can this server handle, so I have used loader.io and run10k requests for 15 seconds. But it seems 20% percent of request fail due to timeout, and the response time keep increasing. Source: almost 2 years ago
  • Why everyone says PostgreSQL better then mongo?
    I ran on the same hardware 5k current get requests through https://loader.io/ tool to the server with each db. Source: over 2 years ago

    Loader.io — Free load testing tools with limitations. - Source: dev.to / over 2 years ago
  • How to stress test my website?
    We put 50 servers of puppets against 50 http servers and see who wins. Ever had 10,000 in your checkout line at once? loader.io is for posers. Also what if there's 250,000 wanting to join the checkout line. Well we can scale to the moon and not handle that. I recommend a waiting room like Queue It. Source: almost 3 years ago
  • Best Way to Benchmark Web Hosting?
    I've used what you said, identical setups (with Wordpress) and some plugins: WordPress Hosting Benchmark tool and WP Performance Tester plus some runs with loader.io. Source: almost 3 years ago
