IDE power at text-editor speed

What's new

A few of the most recent changes. See everything that's shipped.

• Opening a file from the file manager now reuses the running Editora instead of starting a second one. : On Linux and Windows a file manager delivers the path as a command-line argument, which by definition means a new process — so clicking a file while…
• Startup is ~225 ms faster to the first frame that shows your file : (measured on a packaged Linux build opening a file with --expert: median 1702 ms → 1477 ms, ~13%). Four pieces of work were running on…

Features

Keyboard & commands

Command-driven core

Hunting through menus? Every action is a registered Command, bound to a chord or one M-x search away. 600+ commands, nothing buried.

Keymaps your way

Pick Emacs, CUA, Sublime Text, VS Code, or IntelliJ IDEA. Switch live, no restart. Or rebind any command yourself in the built-in keybinding editor (multi-key chords like C-x C-s supported).

Jump-to popups

Lost in a big project? Fuzzy-jump to recent files, symbols, open tabs, and tool windows, plus an Emacs find-file-style path finder.

Multiple cursors

Add a caret at the next occurrence, above/below, or on every occurrence at once, or Alt-drag a column/box selection to edit many places at once, VS Code-style.

Keyboard macros

Record a sequence of edits and replay it: F3 to start, F4 to stop, C-x e to replay. Name and save macros, and bind them to keys.

Emacs heritage

The Emacs editing model, not just its keybindings: a kill ring and a mark ring, C-x r rectangles, narrowing, query-replace, C-u prefix arguments, and structural sexp motion. Emacs is the default keymap.

A menu bar, over the same commands

Prefer to browse rather than recall? File / Edit / Find / View / Navigate / Code / Run / VCS / Tools / Window / Help, built over the command registry, so every item shows its live keybinding. Hide it in one keystroke.

Editing

Snippets

Retyping the same boilerplate? Expand VS Code / TextMate templates with tab stops, mirrors, choices, and variables, all from a prefix + Tab. Ships for all 21 languages.

Smart indentation

Per-language auto-indent on Enter (block openers, matching-pair stanzas, closer re-alignment), plus smart backspace that clears a whole indent level in one press.

Auto-close & bracket matching

Typing ([{ or quotes inserts the closer, type-over to skip, wrap a selection, and Backspace clears an empty pair. The bracket beside the caret is highlighted with its match.

Comment toggling

M-; comments or uncomments the line or selection using the language's syntax (//, #, <!-- -->, /* */, --, …).

Spell checking

Red wavy underlines with right-click suggestions, Add-to-Dictionary, and Ignore: full text for prose, comments & strings for code. Pure-Java Hunspell; English, Spanish, French.

EditorConfig

Honors a project's .editorconfig: indent style/size, tab width, end-of-line, charset, max line length, and on-save trim / final-newline. On by default.

Undo History

An in-session timeline of document checkpoints (one per typing burst). Jump back to any recent state from a filterable popup (M-g v) or the tool window (M-g u).

Code intelligence

Syntax highlighting

TextMate grammars (via tm4e) for 21 languages: Java, Python, Rust, Go, Kotlin, C/C++, C#, Ruby, SQL, Markdown, and more.

Language servers (LSP) Beta

Go-to-definition, code actions, rename, signature help, inlay hints, hierarchy, diagnostics and completions via 22 language servers (Java, TypeScript, Python, Go, Rust, C/C++, and more), auto-detected, never bundled.

Autocomplete

As-you-type completion: a popup for code (LSP + snippets) and inline ghost text for prose. Trigger with C-M-i / M-/.

Run & debug

Run files & main classes

Run a script, or a Maven/Gradle project's main class, from a gutter ▶. Output and stdin go to the Run console, with clickable stack traces and saved run configurations.

Run configurations

Save how a thing is launched — Java main class, Python or shell script, or a make target — with a before-launch build step, a toolbar selector, and a file you can commit so your team gets the same ones.

Debugging (DAP) Beta

Full debugging for Java, Python, and JavaScript: breakpoints, step in/over/out, watches, set-value, run-to-cursor, inline values, and an interactive console.

HTTP client Beta

Run .http / .rest requests from a gutter ▶, with environments, variables, request chaining, and a formatted response view. Built on the JDK HTTP client.

Build tools

Maven, npm, Cargo, Go, and Gradle each get an IntelliJ-style tasks tool window and a streaming console.

Git & diff

Git integration Beta

Native Git: status-bar branch, gutter change bars vs HEAD, a Commit tool window, fetch / pull / push + branches, plus a history/log view, inline blame, and stash.

GitHub integration Beta

Review and check out pull requests, submit reviews, open a file on GitHub at the caret line, and jump from a failed CI log straight to the offending line. Uses your own gh CLI, so Editora never handles a token.

Diff & merge Beta

Side-by-side and unified diff (vs HEAD, a commit, or another file) with word-level highlights and apply-hunk arrows, plus a merge-conflict resolver.

Docs & diagrams

Markdown preview

IntelliJ-style 3-mode view rendered natively with CommonMark + GFM: task lists, code pills, images, LaTeX math, a heading outline, linting, and Export to HTML. Live and theme-matched.

Mermaid diagrams

Render Mermaid diagrams inline in Markdown and in standalone .mmd files, with live linting and export to SVG / PNG / PDF.

Export & print

Export code or the Markdown preview to a syntax-highlighted PDF, HTML, MS Word, or ODF, or print with a preview. Light-themed and generated off-thread.

HTML live preview Beta

Click the globe on any HTML file to open it in a detected browser (Safari, Chrome, Firefox, Edge…), served over a loopback web server with live-as-you-type reload. Sibling CSS, JS, and images included.

Typst

A 3-mode preview for .typ files rendered by the Typst CLI, a tinymist language server, Markdown-style editing, and export to PDF / PNG / SVG.

Diagrams as code

A 3-mode preview for Graphviz DOT (.dot/.gv) and PlantUML (.puml) files via the dot / plantuml CLIs, with export to SVG / PNG / PDF.

Smart file previews

Open a data or config file and get a rendered or plain-English preview: JSON/YAML/TOML/XML trees, OpenAPI docs, and decoded systemd, ssh, Dockerfile, fstab, crontab, and GitHub Actions files.

Workspace & files

Projects

VS Code single-folder workspaces: a root folder plus its own saved session (open files, layout, folds), shown as a filterable file tree. Scaffold one from a template, and commit settings the whole team gets.

{ }

Starting a project

Generate a Maven project from an archetype, git init a folder without a terminal, and create any of about fifty file types from the Project tree with the right package declaration already written.

Editor groups

Two files on screen at once. Split the editor into independent groups with their own tabs, nest the splits, drag a tab between them, and get the whole arrangement back on the next launch.

Bookmarks & notes

Line bookmarks (gutter markers, cross-file jump, per-project), plus Personal Notes attached to a word/line/range, stored outside the file, surviving renames, with Markdown bodies.

Find in files

Project-wide search and replace with a results panel, plus AceJump to leap the caret to any visible spot by typing a label.

File templates Beta

New File From Template: single- or multi-file scaffolds with interactive placeholders (author, date, file name, …).

Read-only / View mode

Toggle a buffer read-only to browse without editing; pager-style Space/Backspace paging and a Word-style View Mode banner.

Remote files (SFTP) Beta

Browse, edit, search, and save files on a remote host over SSH/SFTP. The project tree, search, bookmarks, and notes all work over the wire.

Local file history

IntelliJ-style snapshots of your files over time, on save, auto-save, and before an external reload, so you can diff or restore an earlier version with no Git required.

TODO highlighting

Configurable regex patterns (TODO, FIXME, and your own) are highlighted in the editor and collected in a TODO tool window, with scrollbar and minimap stripes.

Server log viewer

Open a .log file for severity highlighting, a tail -f Follow toggle, open-at-the-tail for huge logs, and live level + regex filtering.

CSV & TSV support

Rainbow per-column coloring, a field readout, and an editable CSV Grid with sort/filter and export to Excel/ODF, plus align/shrink and Markdown-table interop.

Customization & extensibility

AI assistance Beta

One-shot AI actions (explain, rewrite, commit message, inline completion) and an embedded coding agent over ACP. Anthropic or a local model. Off by default.

Themes & fonts

Editora Light and Editora Dark, plus 26 more (Primer, Nord, Cupertino, Dracula and the community set). Five bundled monospace fonts, no install needed, and you can drop in a theme of your own.

Plugins

Extend the editor with commands, tool windows, and integrations. Install from a built-in registry of 19 plugins, or write your own (Java or a simple manifest).

Simple UI mode

One toggle strips the editor to the essentials, hiding the extra toolbar groups, tool-window stripe, breadcrumb, gutter, and minimap for a calm, minimal surface.

Localized UI

The whole interface is translated into English, Italian, Spanish, French, Portuguese, and German, selectable in Settings.

MCP server Beta

Embed a Model Context Protocol server in the running editor so an LLM agent (Claude Code, …) can observe live state and drive the command registry. Loopback-only, token-authed, off by default.

External tools

Define your own CLI commands and run them on the current file or buffer, with $Name$ macros, stdin piping, and output to a console or back into the text. IntelliJ-style.

Doctor

A health screen for every external tool Editora can use: what was found, which version, where it lives, what's only half-configured, and what's missing, with an Install… button where Editora can fetch it for you.

Works with your stack

Syntax highlighting for dozens of languages, and full language-server intelligence — completion, go-to-definition, diagnostics — for 21 of them. Plus live previews for the formats you actually read.

Your keymap, your keys

Bring the muscle memory you already have. Pick a keymap and every shortcut follows, or rebind any command to whatever you like.

Make it yours

Ships with 25+ editor themes (and you can add your own). Try a few right here — the whole site recolors with the editor.

Built for speed

Performance is a first-class goal: the UI thread stays free and work happens incrementally, off-thread, and only on what's visible.

Download

Native installers and self-contained runnable jars for every platform are attached to each release.

Native installer (bundles a Java runtime, nothing else to install), or a self-contained java -jar on JDK 25.

Installers are currently unsigned. On macOS, right-click the app and choose Open the first time.

Build & run from source

Requires JDK 25+. A Maven wrapper is bundled, so no local Maven install is needed.
