VS Code

The AI-first code editor

AI-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.

Agent-first development platform from Google with desktop app and CLI

Google 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.

Lightning-fast Rust-powered code editor

Lapce is an open-source code editor written in Rust, delivering sub-millisecond response times through native GPU rendering via wgpu. It features modal editing inspired by Vim, built-in LSP support for intelligent code completion, and a WASI-based plugin system supporting Rust, C, and AssemblyScript extensions. Includes integrated remote development over SSH, a built-in terminal, and split-pane layouts. Its rope-based text architecture ensures efficient handling of large codebases.

High-performance code editor built in Rust

High-performance code editor built entirely in Rust by the creators of Atom and Tree-sitter. GPU-accelerated rendering and a multicore architecture deliver 10x faster startup and 75% lower memory use than Electron editors like VS Code. Native real-time collaboration that works like Google Docs, deeply integrated AI with agentic editing (Claude and more), and Tree-sitter-powered syntax highlighting. Direct-to-display rendering on macOS. Available on macOS, Linux, and Windows.

Agentic coding platform by Alibaba Cloud

AI IDE with Quest Mode for semi-autonomous long-running development tasks. Features context engineering that automatically surfaces relevant code, documentation, and project knowledge. Supports Claude, GPT, and Gemini models, letting developers delegate complex multi-step coding workflows while maintaining oversight through structured task tracking and progress reports.

Multi-agent AI coding platform

Verdant (also known as Verdent) is an AI-native coding tool by Verdent AI that orchestrates multiple specialized AI agents working in parallel to handle software development workflows. One agent plans architecture, another writes code, a third reviews quality — functioning like a small AI development team. Founded by Zhijie Chen (ex-ByteDance algorithms lead), Verdant achieves 76.1% on SWE-bench Verified, among the top coding agents.

Fork, customize, and ship AI agents on Vercel in minutes

Open Agents is a Vercel Labs open-source template for building and deploying cloud-hosted AI agents. It provides a production-ready Next.js starter with built-in tool use, streaming responses, multi-model support, and deployment on Vercel infrastructure. Developers can fork, customize agent behavior and tools, then ship agent-backed apps in minutes with automatic scaling and edge routing.

Human-in-the-loop web agent you can co-pilot in real time

Magentic-UI is a Microsoft Research web agent with a human-in-the-loop interface for browsing, coding, and file tasks. It plans multi-step actions, asks for approval before executing, and lets users co-pilot by taking over the browser mid-task. Built on AutoGen, it runs a team of specialized agents for web browsing, file handling, and code execution with full action transparency and safety guardrails.

Constrained generation that guarantees valid LLM outputs every time

Guidance is Microsoft's structured generation library that enforces output constraints directly within LLM decoding. It supports JSON schemas, regex patterns, grammars, and interleaved generation-and-control flow to guarantee valid outputs from any compatible model. Works with local models via llama.cpp, Transformers, and remote APIs including OpenAI and Anthropic. Eliminates retry loops and post-processing for structured data extraction.

Free local AI code completion for VSCode

Twinny is a free, open-source AI code completion extension for VS Code that works with any OpenAI API-compatible endpoint including local models via Ollama. It provides real-time inline suggestions, a sidebar chat for code discussion, workspace embeddings for context-aware completions, and a decentralized P2P inference network. A privacy-first alternative to GitHub Copilot with zero licensing cost.

Official Vue.js language tooling and IDE support

Volar is the official Vue.js language tooling framework delivering advanced IDE support for Vue single-file components. It provides real-time TypeScript type inference in templates, intelligent autocompletion for components, props and slots, plus diagnostics from the Vue compiler. Volar powers the official Vue VSCode extension with 7M+ installs. Its core Volar.js layer is framework-agnostic, enabling language servers for other frameworks. MIT licensed with 13K+ stars.

A post-modern modal text editor

Helix is a post-modern modal text editor written in Rust, inspired by Kakoune and Neovim. It ships with built-in Tree-sitter support for syntax highlighting and structural editing across dozens of languages, native LSP integration for autocompletion and diagnostics, and multiple cursors as a first-class feature. Helix requires no plugin system or configuration to be productive out of the box, offering a selection-then-action editing model that reverses the Vim paradigm.
