LoadTester

About LoadTester

A managed load testing service for APIs, websites, and critical user flows. It lets teams start free, run distributed HTTP load tests from a browser or CI/CD, and see live metrics while a test is running. The product is designed to reduce setup work by handling execution infrastructure, scaling, and coordination for you.

It is aimed at developers and teams that need repeatable performance checks before releases, during API validation, or when testing launch capacity. The workflow is built around creating a test scenario, choosing a target URL, selecting virtual users or requests per second, and launching the run. During the test, you can watch throughput, latency, errors, and active users in real time, then review a summary with totals and latency metrics after the run.

The service also supports guardrails for performance testing. You can set thresholds for latency, failure rate, or regressions, and use auto-stop rules when limits are crossed. For release workflows, it can be triggered from CI/CD, connected with webhooks, and paired with Slack or email alerts. Results can be exported as PDF, CSV, or JSON so teams can share them in chats, tickets, or release notes.

The free plan is positioned for lightweight API and website checks, while the paid plan adds higher scale, scheduled tests, CI/CD integration, alerts, regression notifications, and more export options.

Key features:
- Distributed HTTP load tests run from a browser or CI/CD.
- Live charts show requests, latency, throughput, failures, and bottlenecks.
- Thresholds can auto-stop tests when latency or error limits are exceeded.
- Supports API testing, website performance checks, and critical user flows.
- CI/CD-ready workflows include webhooks, Slack alerts, and email alerts.
- Export results as PDF, CSV, or JSON for sharing and review.
- Managed execution handles scaling and coordination without worker fleet setup.
