Open Source Rust Code Editors

Zed is a next-generation code editor designed for high-performance collaboration with humans and AI. Written from scratch in Rust to efficiently leverage multiple CPU cores and your GPU. Integrate upcoming LLMs into your workflow to generate, transform, and analyze code. Chat with teammates, write notes together, and share your screen and project. Multibuffers compose excerpts from across the codebase in one editable surface. Evaluate code inline via Jupyter runtimes and collaboratively edit notebooks. Support for many languages via Tree-sitter, WebAssembly, and the Language Server Protocol. Fast native terminal tightly integrates with Zed's language-aware task runner and AI capabilities. First-class modal editing via Vim bindings, including features like text objects and marks. Zed is built by a global community of thousands of developers. Boost your Zed experience by choosing from hundreds of extensions that broaden language support, offer different themes, and more.

Lapce is a GUI-based, next‑generation code editor written in Rust, using native GPU-accelerated rendering (via Floem and wgpu). It aims to deliver VS Code–level productivity with minimal latency, built-in LSP support, modal editing, remote development capabilities, and WASI‑based plugin extensibility.

JSON Studio is a private, lossless workspace for JSON. Most JSON tools either choke on big files, silently mangle your numbers, or send your data to a server. JSON Studio does none of that. It is a native desktop app built for speed and correctness: open a half-gigabyte file and start navigating immediately, knowing that what you see is byte-for-byte what is on disk. Everything runs on your own machine - no accounts, no uploads, no analytics, no network calls - making it safe for proprietary, regulated or personal data.

A Kakoune / Neovim inspired editor, written in Rust. The editing model is very heavily based on Kakoune.

Rustpad is a minimal open-source collaborative code editor for real-time writing in the browser. It uses operational transformation so multiple users can edit the same document at the same time without overwriting each other. The server is written in Rust, while the front end uses TypeScript, React, WebAssembly, and the Monaco editor. Rustpad is designed to be self-hosted and can run without a database by keeping documents in memory. It also supports optional SQLite persistence for retaining document contents across restarts. The project is especially useful for lightweight pair programming, collaborative note-taking, interviews, teaching, and temporary shared editing sessions.

VTCode is a terminal-based AI coding agent designed to provide semantic code understanding and interactive assistance directly within a command-line environment. It is implemented in Rust and focuses on performance, portability, and deep integration with developer workflows that rely on terminal tools. The system leverages syntax-aware parsing technologies such as tree-sitter and AST-based analysis to understand code structure rather than relying solely on raw text, which enables more accurate and context-aware suggestions. VTCode operates as an agent rather than a simple autocomplete tool, meaning it can interpret user intent, navigate codebases, and assist with multi-step tasks. It is highly configurable, allowing developers to define behavior, prompts, and workflows tailored to their projects. The tool is especially useful for developers who prefer lightweight, local-first environments but still want advanced AI assistance comparable to modern IDE-based tools.
