Open Source Rust Text 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.

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

Haptic is a new local-first & privacy-focused, open-source home for your markdown notes. It's minimal, lightweight, efficient and aims to have all you need and nothing you don't.

Helix is a modal (Kakoune/Vim‑inspired) terminal-based text editor written in Rust. It features modern modal editing, multiple selections, smart syntax highlighting, and built-in language server (LSP) integration leveraging tree‑sitter for fast, incremental parsing and code intelligence.

A fast static site generator in a single binary with everything built in. Forget dependencies. Everything you need in one binary. Zola comes as a single executable with Sass compilation, syntax highlighting, table of contents and many other features that traditionally require setting up a dev environment or adding some JavaScript libraries to your site. The average site will be generated in less than a second, including Sass compilation and syntax highlighting. Zola renders your whole site as static files, making it trivial to handle any kind of traffic you will throw at it at no cost without having to worry about managing a server or a database. From the CLI to the template engine, everything is designed to be intuitive. Don't take my word for it though, look at the documentation and see for yourself.

Crowbook's aim is to allow you to write a book in Markdown without worrying about formatting or typography and let the program generate HTML, PDF and EPUB output for you. Its focus is novels and fiction, and the default settings should (hopefully) generate readable books with correct typography without requiring you to worry about it. To see what Crowbook's output looks like, you can read the Crowbook guide rendered in HTML, PDF or EPUB. Crowbook will parse this file and generate HTML, EPUB, and/or PDF output formats, according to the settings in the configuration file. Crowbook supports HTML, PDF and EPUB (either version 2 or 3) as output formats. See the Crowbook User Guide rendered in HTML, EPUB and PDF. Crowbook uses pulldown-cmark and thus should support most of CommonMark Markdown.

xi Editor (often styled “Xi”) is a project to build a modern, high-performance text editor designed for large files, extensibility, and native UI integration. Its architecture splits a thin UI layer from a high-performance core engine (written in Rust) that handles buffer editing, syntax highlighting, undo/redo, searching, and background processing asynchronously. This separation lets the core focus on speed and concurrency, while multiple frontends (macOS, GTK, web) handle rendering, input, and platform bridging. Xi is designed to scale to huge files (gigabyte scale) without lag, thanks to a rope data structure and efficient diffing algorithms. Plugins communicate with the core via JSON-RPC, enabling asynchronous extensions without blocking editing responsiveness. The overall aim is to reimagine text editing for modern machines and workflows, delivering scalability, modularity, and an editor architecture built for the next decade.

Zee is a modern editor for the terminal, in the spirit of Emacs. It is written in Rust and it is somewhat experimental. In the old tradition of text editor demos, here's what it currently looks like editing its own source code.

Discover the incredible power of a full-blown text expander. No more copying and pasting, create templates once and let Espanso do the rest for you. Customer support replies, sales pitches, medical reports, you name it. Espanso has got you covered. Just press ALT+Space and Espanso’s search bar will open, letting you search for the perfect snippet. Don’t wrap your head around dates. Espanso makes it easy to use them, both past and future ones. Extend Espanso’s capabilities with packages, or create your own and share them with the community on the Espanso Hub. For advanced use cases, you can extend Espanso’s snippets with shell commands or custom scripts. No more copy-pasting from the terminal, inject the output into applications directly.

Markdown-Oxide is a Personal Knowledge Management System(PKM) that composes with your favorite text editor through the Language Server Protocol(LSP). While other PKMs implement their own text editors, markdown-oxide is unbundled: it leaves text editing to a dedicated text editor and focuses solely on robust, performant knowledge management.

markdown-rs is an open-source markdown parser written in Rust. It’s implemented as a state machine (#![no_std] + alloc) that emits concrete tokens, so that every byte is accounted for, with positional info. The API then exposes this information as an AST, which is easier to work with, or it compiles directly to HTML. While most markdown parsers work towards compliancy with CommonMark (or GFM), this project goes further by following how the reference parsers (cmark, cmark-gfm) work, which is confirmed with thousands of extra tests. Other than CommonMark and GFM, this project also supports common extensions to markdown such as MDX, math, and frontmatter.
