Description
PerfDelta is an online platform designed for testing and monitoring website speed, catering particularly to SEO professionals, digital agencies, and internal web development teams. The complimentary test feature allows users to evaluate up to three pages on both mobile and desktop platforms, integrating real-user Core Web Vitals sourced from the Chrome UX Report alongside measurements from Lighthouse labs. Its comprehensive reports enable comparisons between a user’s site and up to two competitors, as well as benchmarks against previously analyzed sites, while also detailing page weight distributions and request timelines, identifying the technologies in use, and providing prioritized recommendations that include estimated savings along with the relevant affected files. For those opting for paid subscriptions, additional features such as scheduled monitoring, performance budgets, email notifications, historical reports, and PDF exports are available; furthermore, Agency and Scale plans also include CSV export options, public dashboards, and a REST API for advanced functionalities. The inclusion of MCP access allows compatible AI agents to request tests and obtain results seamlessly. Clients can benefit from shared reports for performance audits and to assist with ongoing website enhancements, thereby adding value to the overall service.
Description
SpeedOf.Me has measured internet speed in the browser since December 2011, when it shipped as the first HTML5 speed test. It reports download, upload, latency and jitter and plots them live as the test runs, with no app, plugin or download, on desktops, phones, tablets, game consoles, smart TVs and cars.
The method is deliberate: one stream, from the browser, to neutral third-party CDN edge servers in more than 130 locations, over the same open-internet path your browsing and video already take. Tests that hit a server inside your own provider's network with many parallel streams report a best-case peak instead. That number is called Real-World Speed, and because the method has not changed since 2011 the figures stay comparable year over year.
Developers can run the same engine themselves. Drop in api.js, set an account key and domain, call SomApi.startTest(), and results return through callbacks, white-labelled, with nothing to host. Examples ship for vanilla JavaScript, React, Vue, Angular, React Native, Electron, Flutter, iOS, macOS, Android and Windows, and the portal reports calls, geography, device mix and speed trends.
AI agents get the same access through @speedofme/mcp, one npm package that is a Model Context Protocol server, a CLI and a Node SDK, working with Claude, Cursor, Windsurf, Zed, VS Code, Cline, Continue, JetBrains and Goose.
The Internet Speed Atlas aggregates millions of anonymised tests into real-world figures for 119 countries.
