Overview
SonarQube — Continuous code quality and security analysis
Cursor — Cursor is not just VS Code with a chat sidebar — it is the first AI code editor where the agent can actually write, run, and debug code across multiple files without you touching the keyboard. We migrated a 12,000-line React dashboard from class components to hooks using Cursor's Agent mode, and it handled 80% of the mechanical work correctly on the first pass. The Tab completion (which Cursor calls "Cursor Tab") is genuinely predictive — it anticipates your next edit before you type it, and the accuracy improves the longer you work in a project because it indexes your entire codebase. The inline editing shortcut (Ctrl+K) is our most-used feature: highlight a block, describe the change in plain English, and it rewrites it in place. Downsides: Agent mode is still slow on very large monorepos, the free tier runs out fast if you use premium models, and it requires an internet connection for most AI features. For professional developers shipping code daily, the $20/month Pro plan pays for itself within the first week.
