TypeScript is the language where AI coding tools have the least excuse to be wrong. The type system hands a model interfaces, generics, and inferred return types for free — if a tool is going to hallucinate a method that doesn't exist on your type, TypeScript is where you'd expect it to happen least. We checked which tools actually use that advantage, and which ones just run the same completion engine regardless of file extension.
Best overall — Cursor ($30/mo, Premium tier). Its autocomplete reads across files in a way that respects your actual interfaces rather than pattern-matching on similar-looking code — multi-line suggestions that track generics and narrow on discriminated unions instead of guessing. It's built on VS Code, so the extension ecosystem and keybindings carry over; you're not relearning an editor to get this.
Best value — GitHub Copilot ($10/mo, Individual). Deepest GitHub integration of anything on this list, genuinely useful for day-to-day completion, and at a third of Cursor's price. It doesn't do the same depth of cross-file type reasoning, but for a lot of TypeScript work — filling in a function body, extending an existing interface — that gap doesn't show up often enough to matter.
Best free option — Windsurf (Pro and Max are Devin Desktop now; the free daily-quota tier is still Windsurf-branded and still free). Enough quota to actually evaluate it before deciding whether the paid tiers are worth it, which is the bar a free tier should clear and most don't.
Also worth running alongside whatever you pick: Cline (free, open source, Plan/Act modes, MCP support — runs in VS Code) and Aider (free, open source, terminal-based, tight git integration, bring your own API key). Neither is a TypeScript specialist, but both are good enough that "free" stops being a real tradeoff for a lot of workflows.
One honest caveat on the "also worth considering" side: Cody used to belong on a TypeScript shortlist. Sourcegraph made it enterprise-only in July 2025 — if you're an individual developer, it's off the table regardless of how it performs.
