Modern load testing tool for HTTP and API performance testing.
LoadTester is a modern HTTP and API load testing tool built by Cloud Native d.o.o. for engineering teams that need repeatable performance checks. It runs distributed load tests from your browser or CI/CD pipeline, with live analytics, p95/error-rate thresholds, scheduled baselines, and run-to-run comparisons — without any infrastructure to manage. Free plan available.
Run application and HTTP load tests in minutes.
Set up a scenario, hit run, and watch the data live. Whether you start from the dashboard or from CI/CD, the workflow stays simple — all of it driven through the UI.
Know if your app can handle the next release, campaign, or customer spike.
LoadTester is for teams that want a clear answer without setting up workers, dashboards, and scripts first.
Features that remove the painful parts of performance testing.
LoadTester is a modern load testing tool for HTTP load testing and application performance testing, removing the painful parts of performance testing while keeping the workflows developers actually care about.
Instant execution, distributed by default.
Start distributed load tests in seconds. No infrastructure setup, no worker orchestration, no scheduling headaches. Your team focuses on results — we handle worker scaling, infrastructure coordination, and execution flow.
Live analytics
Watch requests, latency, failures, throughput, and bottlenecks in real time while your test is running.
Smart auto-stop
Set failure or latency thresholds and automatically stop tests when things go sideways.
CI/CD ready · Webhooks · Slack & email alerts.
Run tests on every deploy, every PR, or every release candidate. Trigger alerts, workflows, and follow-up actions from your test results with simple webhook integrations.
Specs, side by side. Nothing hidden.
Start with a free load test in seconds, then upgrade when you need higher scale, scheduled checks, API automation, and regression detection across your release workflow.
LoadTester is a modern load testing tool for API load testing, website performance testing, and repeatable release validation. Use the free plan for lightweight checks or upgrade for high-scale testing, CI/CD integration, scheduled tests, and performance regression detection.
Keep load testing close to every release without turning it into a maintenance project.
Trigger tests from your deploy pipeline, release workflow, or internal automation with one API call. Stop building your own load testing tools — start testing.
Release validation
Run a quick performance check before launch to catch regressions while the change is still easy to roll back or fix. Prevent slow releases by testing every deploy.
API confidence
Load test API endpoints, authentication flows, and critical user journeys with the same simple workflow every time.
Team visibility
Share result links in chat, tickets, or release notes so everyone can see the run without digging through logs.
Launch scaling
Validate scaling before product launches. Find bottlenecks in APIs and web apps quickly.
Shared perf view
Give engineering and product teams a shared performance view everyone can act on.
Know your application limits before production does.
Start your first test today. Infrastructure, scaling, and orchestration are already handled.
Why use a load testing tool instead of building it yourself?
A dedicated load testing tool saves time, removes infrastructure overhead, gives you live analytics, supports CI/CD workflows, and makes it easier to repeat tests consistently. Instead of stitching together scripts, workers, dashboards, and thresholds, your team can run tests and act on results immediately.
Do I need to manage any infrastructure?
No. LoadTester handles execution infrastructure, scaling, and coordination so your team can focus on results instead of setup.
Can I use it for API and website load testing?
Yes. LoadTester works for API load testing, website load testing, HTTP endpoint testing, authentication flows, and broader application performance testing use cases.
Can I use it from CI/CD?
Yes. You can trigger tests from your pipeline, automate checks, and use thresholds to catch regressions before release. See our guide on load testing in CI/CD for patterns and examples.
Do you support auto-stop?
Yes. Configure thresholds for latency, failures, or other conditions and stop tests automatically when those limits are crossed.
Is this only for big teams?
No. It is simple enough for small teams that want speed, and powerful enough for larger teams that need repeatable performance workflows.
