Cursor

What it does

Cursor is an AI-native code editor built by Anysphere. Founded in 2022 by a team of ex-OpenAI researchers, by 2026 it became the most valuable AI developer tool company in history: $2 billion annualized revenue, 2 million users, 1 million paying customers.

Cursor is fundamentally a VS Code fork — all extensions, themes, and keybindings carry over. But AI capabilities are woven into every part of the editor: Tab autocomplete, multi-file chat, autonomous agents.

In May 2026, Cursor 3.0 (April 2, 2026) is the active platform with the Agents Window as a separate workspace and tiled multi-agent layouts. Composer 2.5 (May 18, 2026) is the latest proprietary model — built on Moonshot’s Kimi K2.5 with targeted reinforcement learning, scoring 79.8% on SWE-Bench Multilingual at $0.50/$2.50 per MTok. Background Agents run autonomously, BugBot continuously scans the codebase, and Design Mode lets you select UI elements in the browser to feed agents as context. MCP and hooks let Cursor connect directly to your database, docs, and APIs.

Models

Pricing

• Free (Hobby) — Limited Agent and Tab, ~50 slow requests/day
• Pro ($20/mo) — Unlimited Tab, Composer access, all frontier models (Claude, GPT, Gemini), MCPs + Skills + Hooks
• Max ($200/mo) — Background cloud agents, priority GPU access, heavier usage limits
• Business / Ultra — Centralized billing, admin, SSO, privacy mode

Capabilities

• AI-native VS Code fork — extensions/themes/keybindings carry over
• Tab autocomplete (Supermaven-powered) — fastest in market
• Composer 2.5 — multi-file editing (Kimi K2.5 base, May 2026)
• Agent mode — plans, writes, tests, fixes
• Background Agents — parallel AI tasks
• BugBot — automated bug detection
• MCP support
• Project-wide indexing

Strengths

• 30–40% faster coding — measured productivity gains
• Maintains context better than any IDE rival
• 5-minute migration from VS Code
• Composer 2.5 feels like a coding partner, not autocomplete
• Strong agentic workflows

Weaknesses

• Pricing tiers shifted in 2026 — Pro caps frustrate heavy users without Max ($200/mo)
• Performance issues in large codebases
• Agent mode can make sweeping changes hard to review
• GitHub only — no native GitLab support
• Token costs add up fast on Opus-heavy workflows

Ecosystem
