Powerful word processor — just one URL away.

▶ Open EdenText

---

EdenText is a web-based, powerful word processor for everything from quick notes to full-length books. No server, no account — processing runs locally and your documents never leave your computer. Just one URL away, or completely offline as a slim browser app — it opens with under 2 MB of download, dictionaries and fonts follow as needed¹. The interface comes in English, German, Spanish, French, Portuguese, Russian, Ukrainian, Japanese and Chinese (simplified and traditional).

Note

EdenText is young, in beta and actively developed — more features are on the way. It is tested — the full suite plus LibreOffice round-trip checks run on every commit — but expect occasional bugs, and keep backups of documents you care about. The browser copy also keeps the last three versions of the open document, and offers them if it ever fails to load one.

Found a bug, or a document that doesn't look right? Please open an issue — every report helps. Documents that EdenText displays differently from Word, LibreOffice or WPS Office are especially welcome: attach the file (or a stripped-down copy) and it becomes a test case.

Features

• Real page layout — A4/Letter pages, margins, headers & footers, footnotes, columns, page and line numbering, watermarks; mirrored margins and chapters opening on a right-hand page for books
• Opens and saves .odt and .docx, exports PDF; templates (.ott/.dotx) and a letter gallery (DIN 5008); password-protected files in both formats
• Plays well with Word and LibreOffice — documents keep their layout across all three, backed by a sophisticated test pipeline
• Styles — paragraph, character, table and list styles with inheritance, chapter numbering
• Tables with styles, sorting and spreadsheet-style formulas
• Everything a thesis needs — table of contents, captions, cross-references, citations & bibliography, alphabetical index, formulas (LaTeX)
• Review tools — track changes and threaded comments with margin balloons, printable markup, spell check and synonyms (English, German, Spanish, French, Portuguese, Russian and Ukrainian), grammar check (English)
• Private by design — your documents never leave your computer, all processing runs locally; works offline as an installable app. The site counts anonymous visits (GoatCounter, EU-hosted, no cookies); the editor sends nothing. Documents are autosaved in the browser; Recent documents can drop closed ones at the next start or not save them there at all, and a private window leaves nothing behind once it is closed
• Any current browser — in Chrome and Edge, Save writes back to the opened file, and so does Brave once brave://flags/#file-system-access-api is enabled; otherwise each save is a download, so turn on "Always ask where to save" in the browser settings to pick the location

Where the browser keeps EdenText from matching Word or LibreOffice exactly is described under Known limitations.

Gallery

The documents behind these pictures are in docs/showcase/ as .odt and .docx, ready to open in EdenText, LibreOffice or Word. They are built by scripts/showcase/run.mjs; the photographs are NASA's and the book is Lewis Carroll's, both public domain.

Review — tracked changes, threaded comments in the margin, a draft watermark	Book — A5, mirrored margins, chapters opening on a right-hand page, running heads; the numbering restarts after the front matter, so page 11 prints the folio 9
Newsletter — columns, pictures with captions, a sidebar box	Tables — table styles and spreadsheet-style formulas

Desktop app

Each release also carries unsigned desktop installers built with Electron:

• macOS — EdenText-<version>-arm64.dmg (Apple silicon) or EdenText-<version>.dmg (Intel). Drag the app into Applications. As it is unsigned, open it the first time via right-click → Open, or run xattr -d com.apple.quarantine /Applications/EdenText.app.
• Windows — EdenText-Setup-<version>.exe. SmartScreen warns about an unknown publisher: More info → Run anyway.
• Linux — EdenText-<version>.AppImage (chmod +x, then run it) or the .deb (sudo apt install ./edentext_*.deb).

Development

npm install
npm run dev      # dev server with hot-reload
npm test         # test suite
npm run build    # production build → dist/
cd desktop && npm install && npm start   # desktop app on the same build

Built with Svelte 5, TypeScript, Vite and TipTap 3 (ProseMirror).

Self-hosting

There is no backend and no state on the server; documents stay in the browser. A container image is published for each release (amd64 and arm64):

docker run -p 8080:80 ghcr.io/stffnb/edentext

Or serve the files yourself: every release carries an edentext-<tag>.zip of the built app, and npm run build produces the same folder in dist/ — point any web server at it, or build the image locally with docker build -t edentext ..

Loading

EdenText runs entirely in the browser: App.svelte composes the interface around the TipTap document model and its editor extensions. Styles and layout turn that model into editable pages; storage keeps local state and recovery copies. Import and export translate the same model to ODT and DOCX, while browser file APIs save or download the resulting files. See the architecture guides for format and layout invariants.

Footnotes

1. Over the wire, compressed: ~0.6 MB of app code, the rest the spell checker with the dictionary for the browser's language and the fonts a page shows. Everything else is fetched and kept for offline use once it is needed; all fonts, dictionaries and thesauri together are ~15 MB, or ~23 MB with the English grammar check. ↩
