Best System Utilities for Cursor

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.

AppControl is a comprehensive and free Task Manager designed for Windows, offering a complete history of system activities. Users can review days of performance data to pinpoint the causes of high CPU usage, excessive RAM consumption, GPU strain, disk overload, or overheating issues, while also tracking CPU and GPU temperatures over time. Its integrated privacy features monitor which applications have accessed your webcam, microphone, or location, revealing hidden installations and background processes. Unlike the basic End Task function, AppControl allows you to permanently disable troublesome applications, block entire publishers with a single click, and create custom rules that remain in effect. Real-time notifications alert you to any new or suspicious applications and privacy access as they occur. Each running process is accompanied by an easy-to-understand description, eliminating the need for web searches for clarification. Additionally, an optional open-source MCP extension enables integration with AI tools like Claude or Cursor, allowing users to inquire about their PC's activities in simple language, while a command-line interface caters to advanced users. With a lightweight design of just 20 MB, this tool is not only free but also aims to serve as a superior replacement for the standard Task Manager on all managed PCs. Its user-friendly features and powerful capabilities make it an essential tool for anyone looking to optimize their system performance and ensure their privacy.
