Best System Utilities for Claude Code

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.

Latent is a disk cleanup and storage analysis application specifically designed for developers and individuals utilizing local AI tools on macOS. It organizes storage by attributing it to the specific applications and tools that generated it, encompassing elements like model files, build artifacts from development, package caches, Docker data, and application files, while categorizing these items as either recoverable, user-controlled, or protected. Users have the ability to examine disk space by its owner, analyze memory usage, uninstall applications, and locate nearly identical AI-generated images and videos based on similarity. All cleanup actions are logged for potential recovery, allowing file deletions to be restored from the Trash, alongside providing guidance for items managed by external applications. Furthermore, an optional integrated Model Context Protocol (MCP) server enables compatible assistants to analyze scans and suggest cleanup actions, which must be confirmed by the user before implementation. Latent operates locally on macOS 14 or newer, where scanning can be done free of charge, but a license is necessary for file removal, ensuring users maintain control over their data management processes. This app thus empowers users to optimize their storage efficiently while preserving the ability to recover important files if needed.

Veilus is a specialized anti-detect browser designed for managing distinct browser identities on both Windows and macOS platforms. Within Veilus, each profile operates using a modified version of Chromium, featuring its own unique fingerprint, proxy settings, cookies, and site data. Users can customize profiles with individual language, time-zone, and proxy configurations, making it ideal for targeted market analysis. The application offers advanced functionalities such as batch operations, scheduling, snapshots, and options for backing up or synchronizing profiles. Additionally, its integrated local REST API and MCP server allow for seamless integration with AI tools and scripts, enabling the creation and management of profiles, interacting with active webpages, and executing Playwright automation across multiple profiles. However, scripts submitted through the MCP or API are restricted to a maximum of three profiles per execution until they receive approval within the application. Veilus caters to a diverse range of users, including agencies, developers, e-commerce professionals, and QA teams who require effective management of multiple accounts, localization assessments, or repetitive browsing tasks. By default, profiles are stored locally, providing users with easy access and control over their data. The versatility and robust capabilities of Veilus position it as an essential tool for those engaged in complex online operations.
