Here is where each fits, written as fairly as we can manage. Reviewed 19 July 2026 Competitor claims reflect publicly available vendor materials reviewed on that date. ![Evaluat logo](https://www.evaluat.com/favicon.svg) Evaluat ### Real-browser performance testing Evaluat runs each virtual user in an isolated real browser and reports Core Web Vitals, Navigation Timing, and Apdex under load, with session video, network logs, and console logs for every user. ![Loadero logo](https://www.evaluat.com/logos/competitors/loadero.png) Loadero ### Real-browser WebRTC and load testing Loadero is a cloud testing platform from TestDevLab that launches thousands of real Selenium-driven Chrome and Firefox browsers running scripted journeys. Its standout is WebRTC and video-conferencing testing, with simulated webcams and microphones and media-quality metrics like MOS, bitrate, frame rate, and packet loss. **The categorical difference:** Loadero is built for WebRTC and video-conferencing load, scripted in JavaScript, Python, or Java. Evaluat is built for web performance under load, recorded with no code; it reports Core Web Vitals and Apdex, and can generate an Executive Summary. At a glance ## Capability comparison | Capability | Evaluat | Loadero | | -------------------------------------------- | ---------------- | ------------ | | Real browser per virtual user | Yes | Yes | | No-code scenario builder | Yes | No | | Core Web Vitals (LCP, INP, CLS) under load | Yes | No | | Apdex score | Yes | No | | Executive Summary | Yes | No | | Per-session video for every user | Yes | Limited mode | | Full network and console logs per session | Yes | Partial | | Step-by-step pass/fail playback | Yes | Yes | | UK and EU infrastructure | Yes | No | | Scripted journeys (JavaScript, Python, Java) | Visual scenarios | Yes | | Per-user network conditioning | No | Yes | | WebRTC / real-time media testing | No | Yes | \*Executive Summary is not available on the Starter plan. *** When Loadero is the right call ## Loadero is genuinely the better tool in a couple of situations. **You are testing WebRTC or video calls.** Loadero is purpose-built for real-time media: it simulates webcams and microphones, runs multi-party calls, and reports MOS, bitrate, frame rate, and packet loss. Evaluat does not test media streams at all. For a Zoom-style or Twilio-style application, Loadero is the right tool. **You need deep scripted control and per-user network shaping.** Loadero scripts journeys in JavaScript, Python, or Java, and can throttle bandwidth and inject packet loss per participant. If your test needs that level of custom code and network simulation, Loadero gives you more rope than a visual editor. *** When Evaluat is the right call ## Evaluat goes deeper on web performance. **You want results without writing code.** Evaluat scenarios are built in a visual step editor and run in real browsers; there are no scripts to write or maintain. Loadero requires a script in JavaScript, Python, or Java for every test. Evaluat also reports LCP, INP, CLS, plus FCP and an Apdex score for the run, which Loadero does not produce as of the published date. **Your stakeholders need the result, not the raw numbers.** Evaluat can distil a run into an Executive Summary: a plain-language verdict with a health score, the key findings ranked by severity, and the recommended fixes. Loadero gives you graphs, logs, and Gantt charts to interpret yourself. **You need to debug failures forensically.** Evaluat keeps session video, full network logs, console output, and step-by-step pass and fail status for every virtual user, so you can watch the exact session that failed. Loadero's full per-session video is limited to a low-participant recording mode, separate from its high-scale load mode. **You need data residency.** Evaluat keeps test data in the region the test ran in, with live test regions in the UK and the EU. Loadero's locations set where traffic originates, not a data-residency commitment. Common questions ## FAQ ### Does Loadero measure Core Web Vitals? As of the published date, no. Loadero reports machine metrics and WebRTC media quality (MOS, bitrate, frame rate, packet loss), not Google's Core Web Vitals. Evaluat reports Core Web Vitals (LCP, INP, CLS), plus FCP, for every run. ### Do I have to write code to use Evaluat? No. Evaluat scenarios are built in a visual step editor with no scripts, and every virtual user runs them in a real browser. Loadero requires a script (JavaScript with Nightwatch, Python, or Java) for every test. ### What is the Executive Summary? After a test, you can generate an Executive Summary: a plain-language verdict with a health score, the most important findings ranked by severity, and recommended fixes, grounded in the run's Core Web Vitals, Apdex, error rates, and slowest URLs. It turns a dense report into a two-minute read you can share with stakeholders. ### Can Evaluat test WebRTC or video calls? No. Evaluat tests web application performance under load. Real-time media testing (webcam, microphone, multi-party calls, MOS) is Loadero specialty and outside Evaluat scope. ### Does Evaluat keep a record of every virtual user? Yes. Every virtual user has session video, full network logs, console output, and step-by-step pass and fail status. When a run regresses you can watch the exact session that failed instead of inferring it from aggregate charts. ### Is Evaluat a replacement for Loadero? For web performance testing of customer journeys, with Core Web Vitals and a no-code workflow, yes. For WebRTC and video-conferencing testing, no; that is what Loadero is built for. They solve different problems. Methodology ## Sources We compare each product against the buyer job it is built to do, using first-party vendor documentation and product materials.
