Cursor

Cursor earns the #1 spot not because of marketing but because it ships the only product that treats your entire codebase as context, not just the open file. Built on VS Code internals with a purpose-built AI layer, Cursor's Composer mode lets you describe a multi-file change in plain English and watch it execute across your repo. In independent benchmarks on SWE-bench, Cursor with Claude 3.7 Sonnet solved 38% of real GitHub issues — the highest of any tool tested. Pricing starts at $20/month for Pro, which includes unlimited completions and 500 premium model requests. The counterintuitive finding: Cursor is weakest at autocomplete snippets (where Copilot still leads) but dominant on architectural refactors and bug hunts that span 10+ files. For senior engineers, that trade-off is straightforwardly worth it.
