#1Cursor★ Buy· starter★ 4.7 · 412 reviews AI-first code editor — understands your entire codebase, writes and debugs alongside you.
The default AI IDE, for better and worse
Cursor has become the de facto AI-native editor for a reason: Tab completion and Composer genuinely change how engineers work. The pricing is defensible, but the VS Code fork creates real lock-in risk.
Google's AI coding assistant — Copilot competitor with deep Google Cloud integration and a generous free tier.
Free Copilot — and a serious one for Google Cloud teams
The 180K-completion-per-month free individual tier is the most generous in the category. For Google Cloud / BigQuery / Firebase teams, the integration depth justifies the paid tier; for everyone else, "free" is the main reason to try.
AI-native full-stack app builder — describe what you want, get a working React + Supabase app in one prompt.
The vibe-coding king — until you need to ship something complex
Lovable is the fastest way to get a deployed full-stack React + Supabase app from a prompt. The $100M ARR and $1.8B valuation are real. The cap is real too: AI-generated greenfield apps don't hold up well under feature pressure or non-trivial backend logic.
Vercel's generative UI tool — prompt-to-React-component with shadcn/ui and Tailwind output.
Vercel's frontend generator has grown up
v0 has evolved from a prompt-to-component demo to a real frontend scaffolding tool tightly integrated with Vercel and shadcn/ui. It's excellent for prototyping; less useful if you're not already on the Vercel stack.
AI code review with full-codebase context — finds architectural and cross-file bugs CodeRabbit misses.
AI code review with senior-engineer judgment
Greptile reads your whole codebase before reviewing each PR, so it catches the cross-file and architectural issues CodeRabbit misses. Smaller, more expensive, and more loved by senior engineering teams.
Prompt-to-full-stack web app — AI builds, runs, and deploys React/Next.js apps right in the browser.
Full-stack prompt-to-app, rough edges included
Bolt.new delivers on the "prompt a full-stack app in the browser" promise better than most competitors. But token burn is high and the output has a ceiling that arrives faster than the marketing suggests.
#7Windsurf★ Evaluate· free★ 4.7 · 62 reviews Agentic AI IDE — takes multi-step actions autonomously to write, debug, and ship code.
Cursor's closest competitor, one lap behind
Windsurf (Codeium's IDE) is the serious alternative to Cursor, with real advantages on Cascade agent workflows. But the broader ecosystem and ship velocity keep it in Cursor's shadow.
#8Replit★ Evaluate· starter★ 4.6 · 154 reviews Browser-based IDE with AI agent — build, deploy, and host full apps without leaving the tab.
From browser IDE to agent-first platform
Replit Agent 2 has pushed Replit ahead of the pure in-browser IDE category. But serious developers still hit its limits, and it's not the right choice if you don't need the hosted/always-on piece.
