Anycode — Open-Source Web ADE Where Humans and AI Build Together

Anycode Ade — Sun, 26 Jul 2026 21:01:31 +0000

Hey DEV Community! 👋

We want to introduce Anycode — an open-source web-server application where humans and AI agents build software together.

Unlike most modern AI editors, Anycode is NOT a VS Code fork. It's built entirely from scratch to deliver maximum performance, flexibility, and native agent integration.

🛠️ Architecture at a Glance

Frontend: React 19 + custom web-tree-sitter WASM virtual-rendering engine
Backend: High-concurrency Rust (Axum + Tokio + Socket.IO WebSockets)
Protocols: Native Agent Client Protocol (ACP) & Language Server Protocol (LSP)

Run Anycode locally or host it remotely to interact with your local files, PTY terminals, and AI agents directly in any browser.

🔥 Key Features

⚡ Custom Ultra-Fast Editor: Built with a custom virtual-rendering engine powered by web-tree-sitter. Ultra-smooth 120+ FPS performance on large 100k+ line files with minimal memory and cpu usage.
🤖 Native Agent Client Protocol (ACP): Deep integration with AI agents (Claude Code, Codex, OpenCode, and local LLMs via Ollama) supporting streamed tool calls, permission controls, reasoning selectors, and history-backed undo.
🖼️ Flexible Free-Pane Layout: Fully customizable workspace layout. Split, dock, and resize editor panes, PTY terminals, AI agent chats, Git panels, and search tabs into any layout configuration.
👀 Filesystem Watcher: Real-time file system monitoring for instant UI updates and live diff visualization whenever AI agents or external processes modify code.
🦀 High-Performance Rust Core: Async Rust backend (Axum + Tokio + Socket.IO) driving real-time file I/O and Language Server Protocol (LSP) handling.
💻 Integrated PTY Terminals: Full-featured terminal emulator running over WebSockets for multi-session shell execution.
🧠 Language Server Protocol (LSP): Code intelligence featuring multi-language autocomplete, Go-to-Definition, Hover docs, and real-time diagnostics.
🌿 Built-in Git Integration: Full-featured Git Changes panel with per-file revert, commit, push, and pull capabilities without leaving the browser.
🔎 Global Search & File Tree: Fast full-text project search and interactive file tree navigation.
🎨 Themes & Typography Customization: Customizable editor color themes, dark/light modes, font sizes, and custom typography settings.

⚡ Quick Start & Run

Install Anycode:

curl -fsSL https://raw.githubusercontent.com/anycode-ade/anycode/main/install.sh | sh

Launch Anycode in your project folder from terminal:

anycode

Open the printed Web URL (e.g. http://localhost:3000) in any browser!

⚙️ Setup & Prerequisites

For privacy, security, and local isolation, Language Servers (LSP) and AI agents are not bundled — they must be installed manually on your machine:

Language Servers: See the LSP Setup Guide to enable code intelligence (rust-analyzer, vtsls, etc.).
AI Agents: See the ACP Setup Guide to connect Claude Code, Codex, OpenCode, or local LLMs.

That’s it — no extra configuration is required. Anycode is built to keep your setup fast and straightforward.

anycode

anycode is a web platform where people and agents build together. Run it locally or remotely and work from any device you want: desktop, laptop, mobile, or even VR. Use any agent, including Codex, Claude Code, OpenCode, as well as local models.

Features

Ultra-fast custom editor: Exceptionally fast and highly optimized virtual rendering engine based on tree-sitter parser, delivering superior performance for large codebases.
Multi-language support: Work with various programming languages in a single environment.
Advanced code experience: Utilizes a custom code component based on web-tree-sitter for efficient parsing, syntax highlighting, and real-time code analysis.
LSP integration: LSP support for intelligent code completion, go-to-definition, hover information and real-time diagnostics.
File system integration: WebSocket-based backend for browsing and editing files from your local filesystem.
Changes: Built-in git Changes panel, per-file revert, commit, push, and pull.
Free layout: Flexible pane layout for arranging the…
