Anysphere Closed source Visit Website Docs Download Share X Facebook Reddit Telegram Bluesky Email Anysphere's AI-native development platform. Cursor 3 (April 2026) rebuilt the editor around an Agents Window: a unified workspace for managing local, cloud, and background agents across multiple repositories. Powered by Composer 2 (Anysphere's in-house model), Claude Opus 4.7, GPT-5.5, and Gemini 3 Pro, with JetBrains ACP integration and an Agent CLI. ## + Pros - Most popular AI-native IDE — large community, extensive third-party extensions, and broad model support - Background Agent runs autonomously in cloud VMs: clones repos, edits files on a branch, and opens PRs - BugBot automatically reviews PRs on GitHub and leaves actionable comments linked to Cursor - Plan Mode for complex multi-step reasoning before execution, with Mermaid diagram output - Multi-agent support: parallel sub-agents for concurrent task execution - Team Plugin Marketplace and MCP Apps for one-click tool integrations - JetBrains IDE support since March 2026 — not limited to VS Code fork ## − Cons - Proprietary fork of VS Code — not open source, and deviates from upstream VS Code over time - Background Agent and cloud VMs are usage-billed on top of the subscription — costs can escalate - BugBot requires Max mode (Pro plan minimum) — not available on the free Hobby tier - Security concerns with background agents: auto-runs commands, prompt injection risk acknowledged in official docs - Teams plan at $40/user/mo is significantly pricier than GitHub Copilot Business ($19/user/mo) ## Pricing ### Hobby Free Limited features ### Pro $20/mo Full features, Composer 2 ### Pro+ $60/mo Higher limits, background agents ### Ultra $200/mo Maximum usage ### Teams $40/user/mo Team management ### Enterprise Custom SSO, compliance Cursor is the AI-native development platform from Anysphere. Originally a VS Code fork with AI woven into every part of the editor, it grew into the fastest-scaling SaaS company on record — around $2B ARR and one million paying customers by early 2026. Cursor 3 (April 2026) rebuilt the interface around an Agents Window: a single workspace for orchestrating local, cloud, and background agents across multiple repositories. The product spans a continuous autonomy slider — from Supermaven-powered Tab autocomplete and Cmd-K inline edits, through Composer for multi-file edits, up to Background Agents that clone your repo to a cloud VM, run tests, and open PRs. Cursor 3 also introduced Composer 2, Anysphere's own in-house frontier coding model, alongside Claude Opus 4.7, GPT-5.5, and Gemini 3 Pro. JetBrains integration via the Agent Communication Protocol extended the surface beyond the standalone editor. ## Key Features • Agents Window (Cursor 3): unified workspace for local, cloud, and background agents • Background Agents: up to 8 parallel cloud agents on isolated VMs, PR-ready • Composer 2: Anysphere's in-house frontier coding model with high Pro limits • Multi-model: Claude Opus 4.7, GPT-5.5, Gemini 3 Pro, plus BYOK • Tab completion powered by Supermaven (acquired 2025) • Multi-repo workspaces and plugin/MCP marketplace • Automations: event-triggered agents (PR review, CI, alerts) • JetBrains ACP integration: agent features in IntelliJ, PyCharm, WebStorm • Agent CLI and Slack integration for headless workflows ## Version History v3.4 (May 2026) May 13, 2026 Development environments for cloud agents: dedicated sandboxed VMs per agent run. Context Usage Breakdown introduced in v3.3 (May 2026). Multitask, Worktrees, and Multi-root Workspaces in v3.2 (Apr 2026). Cursor 3.0 (Apr 2026) launched a redesigned interface with the new Agents Window, tiled layout, and upgraded voice input. v2.5–v2.6 (Feb–Mar 2026) Mar 1, 2026 Plugins system and Team Plugin Marketplace launched. MCP Apps for one-click MCP server installation. Sandbox Network Access Controls for background agents. Async subagents for parallel task execution. JetBrains IDE support released (Mar 2026). v1.0 (Jun 2025) Jun 5, 2025 1.0 milestone: BugBot for automated PR code review (GitHub integration), Background Agent GA (cloud VM agents that clone repos and open PRs), one-click MCP installation, Memories first look, Jupyter Notebooks support, and coding agents in Slack. Best for Developers who want a unified workspace for editing code and orchestrating parallel AI coding agents Capability Agents Window, Background Agents (8 parallel), Composer 2 in-house model, multi-repo workspaces, JetBrains ACP Runs on Standalone IDE (VS Code fork), JetBrains via ACP, Agent CLI, Slack Signature Snippet Copy ``` `Cmd-K in a Next.js file: "Add input validation and error handling to this route." Cursor analyzes the function, checks related types and imports zod, and rewrites the handler with proper error boundaries. Hand off the same task to a Background Agent and it works on a separate branch, runs the tests, and returns a PR with a video of the agent session.` ``` ## More in this Space SO ### Sourcery Closed source AI code review platform for the AI era.
