The best coding agent

What it is

Cursor is an AI-powered coding agent and development environment designed to accelerate software creation. It functions as both a desktop IDE (Cursor Desktop) and a command-line tool (Cursor CLI), integrating AI assistance across coding, debugging, planning, and collaboration workflows. It targets individual developers and enterprise teams building world-class software.

Main Features

Agentic Development (Cursor Agent)

• Autonomous task execution: agents can plan, build, test, and demo features end-to-end without constant user intervention.
• Parallel execution: multiple agents can work simultaneously on separate tasks.
• Cloud agents: agents run on remote compute, enabling continuous work even when the user is offline.
• Composer (versions 2.0, 2.5): a built-in tool for composing and refining code with AI assistance.

Intelligent Autocomplete (Tab)

• Specialized Tab model predicts the user's next action with high speed and precision.
• Context-aware completions based on the current codebase and file structure.

Codebase Understanding

• Full codebase indexing: Cursor learns how the entire codebase works, regardless of scale or complexity.
• Semantic search: natural language queries can locate relevant code, variables, and patterns.
• Secure indexing with published research (2026) on codebase indexing.

Integration & Collaboration

• Slack integration: users can ask Cursor directly via Slack to take actions (e.g., create a PR).
• GitHub PR review: Cursor can review pull requests and propose changes.
• CLI (Command Line Interface): accessible via terminal for command-line assistance (cursor command).
• Jira integration (noted in changelog).

Model Flexibility

• Users can choose between cutting-edge models: OpenAI (GPT-5.5), Anthropic (Opus 4.8), Gemini 3.1 Pro, Grok 4.3, and Cursor's own models.
• Model usage is per-task, enabling optimal model selection for specific tasks.

How it works

Using Cursor Desktop (IDE)

• Users install the desktop application (available for Linux, macOS, Windows from changelog context).
• The interface provides a code editor with AI-powered features: inline code suggestions, agent chat (Composer), mission control view for multiple windows.
• Example workflow: open a project, type a task like "Build Landing Page", Cursor reads attached docs (e.g., about-acme.md, brand-guidelines.pdf) and generates code autonomously.

Using Cursor CLI

• Install via curl: curl https://cursor.com/install -fsS | bash
• Users can run commands directly in the terminal with AI assistance, e.g., "plan mission control interface". The agent reads files, plans steps, and executes.
• Supports shell commands and file references.

Collaboration & Communication

• In Slack, users can @cursor with a request (e.g., "can you take a stab?"). Cursor responds with an app message containing a plan or PR link.
• GitHub integration: Cursor can view PRs, open them in the desktop, or in the web.
• Team dashboards are available for research insights (e.g., Acme Research Dashboard) that wire up data sources like Snowflake.

Key Points

• Trusted by over half of the Fortune 500 companies (according to the page).
• Cursor is developed by Anysphere, Inc., an applied research team pushing the boundaries of AI-assisted software development.
• Significant productivity gains reported: internal adoption at Stripe rose from single digits to over 80% after initial rollout.
• Cursor offers an "autonomy slider": users can choose between Tab (suggestions), Cmd+K (targeted edits), or full agentic mode.
• The product supports both individual developers and enterprise teams with dedicated enterprise features (pricing, security, scale).
• SOC 2 certified for security.
