Loadster is a cloud-based load testing and synthetic monitoring platform for engineers who want to know how their applications behave under real traffic.

Tests run with three types of bots: Protocol Bots for HTTP testing, headless Browser Bots that render full pages and execute JavaScript in real Chrome browsers, and Playwright bots for when you want to use Playwright JS directly.

Loadster scripts can be recorded from Chrome or Firefox with the Loadster Recorder extension, edited in a built-in editor with variables, datasets, and shared includes, and then replayed from multiple cloud regions.

Each test run returns detailed page timings (TTFB, FCP, LCP, CLS, etc) alongside resource waterfalls, screenshots, and full traces you can step through in a self-hosted trace viewer. Tests scale from a handful of virtual users (bots) to hundreds of thousands across distributed cloud engines without you provisioning anything.

The same scripts can be set up as monitors that run on a schedule from chosen regions. Notification policies route incidents to email, SMS, voice, or integrations like Slack and PagerDuty. Projects, roles, and shared test history keep teams aligned on what passed, what failed, and what changed.

Pricing is usage-based via Loadster Fuel, with 50 free units on sign-up and no credit card to start.

Questions & Answers

As answered by people managing FreeLoadTest and Loadster.

What makes your product unique?

FreeLoadTest's answer

FreeLoadTest is built for instant, no-signup load testing in the browser. Unlike heavy CLI or enterprise tools, you can paste a website or API URL, run a short controlled test, watch live stats, and download a clean report in minutes. It focuses on practical launch-readiness signals p95/p99 latency, error rate, timeouts, status codes, and RPS , rather than complex scripting or large-scale distributed testing. Safety is part of the product: conservative limits, permission confirmation, and abuse controls make it useful for quick checks without turning it into a misuse platform.

Why should a person choose your product over its competitors?

FreeLoadTest's answer

Choose FreeLoadTest when you need a fast answer, not a full performance engineering setup. Compared with tools like Loader.io, k6, or JMeter, FreeLoadTest is simpler to start: no install, no account, no script writing, and no test-plan setup. It is ideal for pre-launch checks, debugging a slow endpoint, or comparing before-and-after deploy results. If you need CI automation, complex user journeys, or very large distributed tests, a dedicated load testing stack is better. If you want a quick, readable performance report for a URL you own or have permission to test, FreeLoadTest is the faster path.

How would you describe the primary audience of your product?

FreeLoadTest's answer

FreeLoadTest is for developers, indie hackers, startup teams, QA freelancers, small agencies, students, and founders who need a quick way to validate how a website or API behaves under light load. The audience is people preparing for launch, shipping a new feature, or checking whether a recent change made an endpoint slower or less reliable. They usually want evidence they can share ,latency percentiles, errors, timeouts, and downloadable reports ,without spending time learning a full load testing platform.

What's the story behind your product?

FreeLoadTest's answer

FreeLoadTest started from a simple frustration: most load testing tools are powerful, but too heavy for the first question every team asks before launch, โ€œDoes this URL hold up under a small burst of traffic?โ€ Teams often do not need scripts, agents, or a full testing workflow on day one. They need a safe, fast way to paste a URL, run a short test, and get a report they can trust. FreeLoadTest was built to fill that gap: a lightweight browser-based tool for permission-based website and API checks, with live results and downloadable reports, so teams can catch slow pages, API timeouts, and error spikes before users do.

Who are some of the biggest customers of your product?

FreeLoadTest's answer

FreeLoadTest is an early-stage product and does not yet have large public enterprise customers. It is currently used by indie developers, startup teams, QA freelancers, and small agencies running quick pre-launch and post-deploy performance checks on websites and APIs they own or have permission to test.

Which are the primary technologies used for building your product?

FreeLoadTest's answer

Next.js โ€” App Router, API routes, and server-side test execution React โ€” browser UI for test setup and live results TypeScript โ€” frontend and backend type safety Node.js โ€” HTTP load generation and request orchestration Python โ€” standalone load test backend (loadtesttool.py) FastAPI โ€” Python API with the same endpoints as the Next.js backend httpx โ€” async HTTP requests for Python load generation Uvicorn โ€” ASGI server for the Python backend Server-Sent Events (SSE) โ€” real-time live stats during a test In-memory job store โ€” short-lived test job tracking and snapshots JSON / CSV reporting โ€” downloadable performance reports
