CursorAI-first code editor built as a VS Code fork that deeply integrates LLMs into every part of the development workflow. Features Tab autocomplete with multi-line predictions, Cmd+K inline editing, AI chat with full codebase awareness, and Agent mode for autonomous multi-file edits with terminal execution. Supports GPT-4, Claude, and more with automatic context from project files and docs. Includes privacy mode for SOC 2 compliance. The leading AI-native IDE with 100K+ paying users.VS CodeMicrosoft's free, open-source code editor that has become the most widely used development environment in the world. Lightweight but powerful, with built-in Git, integrated terminal, IntelliSense, debugger, and tens of thousands of extensions. Recent updates add Agent mode for delegating coding tasks to AI, Model Context Protocol (MCP) support, and Next Edit Suggestions. Native GitHub Copilot, remote development via SSH/containers/WSL, and a browser version at vscode.dev.Google AntigravityGoogle Antigravity is Google's AI-powered agentic development platform, announced in November 2025 and expanded with Antigravity 2.0 at I/O 2026, that places autonomous AI agents at the center of software development. Distributed as both a VS Code-based desktop app and the new Antigravity CLI, it runs planning, implementation, and verification agents — backed by Gemini 3.1 Pro/Flash, Claude Sonnet/Opus 4.6, and GPT-OSS 120B — across editor, terminal, and browser.JunieJunie is JetBrains’ AI coding agent for autonomous task execution inside JetBrains IDEs and Android Studio. It helps plan implementation steps, write and inspect code, run tests, and collaborate through code and ask modes. Current JetBrains AI positioning lists Claude, GPT, Gemini, Grok, local-model options, and provider-choice paths, with AI Ultimate recommended for regular Junie usage.StackBlitzStackBlitz is a browser-based development environment powered by WebContainers — a WebAssembly micro-OS that runs Node.js natively inside the browser.
