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. ![OctoPerf logo](https://www.evaluat.com/logos/competitors/octoperf.png) OctoPerf ### JMeter-based load testing at scale OctoPerf is a commercial load and performance platform built as a GUI and cloud layer on Apache JMeter. Its engine generates protocol-level virtual users at massive scale, it is fully JMeter-compatible (import and run .jmx, plus Postman, HAR, Selenium, and Playwright), and it ships as both SaaS and self-hosted on-premise. **The categorical difference:** OctoPerf is a JMeter-based load tester: its engine generates protocol-level virtual users at massive scale, and it can drive a few real browsers for client-side timing. Evaluat runs a real browser for every virtual user, reports Core Web Vitals and Apdex, and can generate an Executive Summary. At a glance ## Capability comparison | Capability | Evaluat | OctoPerf | | ------------------------------------------------ | ------- | ------------- | | Real browser for every virtual user | Yes | Capped sample | | No-code scenario builder | Yes | Partial | | Core Web Vitals (LCP, INP, CLS) under load | Yes | No | | Apdex score | Yes | Yes | | Executive Summary | Yes | Partial | | Per-session video for every user | Yes | No | | Full network and console logs per session | Yes | Partial | | Step-by-step pass/fail playback | Yes | Yes | | UK and EU infrastructure | Yes | Partial | | HTTP / API / protocol load at scale | No | Yes | | Runs existing JMeter / Postman / Selenium assets | No | Yes | | Self-hosted / on-premise | No | Yes | \*Executive Summary is not available on the Starter plan. *** When OctoPerf is the right call ## OctoPerf is genuinely the better tool in a couple of situations. **You need protocol or API load at massive scale.** OctoPerf's engine drives millions of HTTP virtual users and runs your existing JMeter .jmx plans, plus Postman, HAR, and Selenium assets. Evaluat does no protocol or API load. For backend and API capacity testing, OctoPerf is the right engine. **You need self-hosted or on-premise load generation.** OctoPerf runs on-premise via Docker or Kubernetes, with SSO and full data ownership, for air-gapped or strict-compliance environments. Evaluat is a cloud platform. *** When Evaluat is the right call ## Evaluat measures every real user, not a sample. **You need real-browser metrics for every user, not a sample.** Evaluat runs a real browser for every virtual user and reports LCP, INP, CLS, plus FCP and Apdex for the run. OctoPerf's real-browser virtual users are capped (one Playwright user costs roughly 200 protocol users), so its browser metrics come from a small sample beside the protocol load. **You want a plain-language verdict out of the box.** Evaluat can produce an Executive Summary for a run: a verdict with a health score, the key findings ranked by severity, and recommended fixes. OctoPerf can generate narrative only by wiring its own MCP server to an AI assistant you provide; there is no native written verdict. **You need to debug failures forensically.** Evaluat keeps session video, full network logs, console output, and step-by-step pass and fail for every virtual user. OctoPerf gives you request and response debugging on a single validation user, not video or console for the run. **You need data residency without running your own servers.** Evaluat keeps test data in the region the test ran in, with live test regions in the UK and the EU, without you managing infrastructure. Common questions ## FAQ ### Does OctoPerf measure Core Web Vitals? As of the published date, OctoPerf reports load and render time, not the named Core Web Vitals (LCP, INP, CLS). Evaluat reports Core Web Vitals (LCP, INP, CLS), plus FCP, for every run. ### Does OctoPerf have an Apdex score? Yes, OctoPerf reports Apdex, and so does Evaluat. The difference is that Evaluat measures it from a real browser for every user, alongside Core Web Vitals. ### How many real browsers can OctoPerf run? OctoPerf's real-browser virtual users are capped and costly (one Playwright user costs roughly 200 protocol users), so they are used as a small sample, not the main load. Evaluat runs a real browser for every virtual user. ### 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 do protocol or API load like OctoPerf? No. Evaluat tests user-facing web applications in the real browser. Protocol and API load at scale is a different layer, outside what Evaluat does. ### 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 OctoPerf? For real-browser experience under load, yes. Protocol and API load at scale is outside what Evaluat does.
