A native macOS EPUB reader and Markdown editor with warm themes and highlighting, built for focused reading. 阅读是一座随身携带的避难所。
BabyReader is a native macOS app for reading and editing Markdown, with full EPUB support. Drop in a file, read it in a warm environment designed for long sessions, then Cmd+E into a full editor when you need to write. No browser, no tabs, no ads — just the text.
- Dark & light themes — warm dark (terracotta accent) and warm paper (gold accent), switchable with one click; window chrome follows the theme
- EPUB rendering — built-in parser handles images, embedded resources, table-of-contents navigation, and continuous scrolling
- Highlighting — select text in EPUB to highlight; highlights persist across sessions, auto-save to
~/Documents/BabyReader/as Markdown, and export via Cmd+Shift+E - Reading position — remembers where you left off in every file via scroll position
- Reading-first, editing-ready — opens to rendered view; Cmd+E toggles a full editor with auto-save (Markdown/TXT only; EPUB is read-only)
- Multi-window + Split View — independent macOS windows; supports native full-screen Split View
- Font scaling — Cmd+/Cmd- zoom, rem-based typography that scales cleanly
- File association — double-click
.md,.txt,.epubto open directly - No dependencies — pure Objective-C + WKWebView, no Electron, no Node.js
- macOS 11 Big Sur or later
- Apple Silicon Mac
Download BabyReader-v2.0.3.zip from the latest GitHub release, unzip it, and move BabyReader.app to your Applications folder before opening it.
Because BabyReader is an independent open-source app without Apple notarization, macOS may block the first launch.
Recommended first launch:
- Move
BabyReader.appto/Applicationsor~/Applications. - Right-click
BabyReader.app→ Open → confirm. - If macOS still refuses to open it, remove the download quarantine flag once:
xattr -dr com.apple.quarantine /Applications/BabyReader.appIf you installed it in your user Applications folder instead, use:
xattr -dr com.apple.quarantine ~/Applications/BabyReader.appAfter that, BabyReader should open normally. macOS may not ask to make it the default reader automatically; you can still use Open With for .md, .txt, and .epub files.
# Requires macOS with Xcode command-line tools
xcode-select --install # if not already installed
git clone https://github.com/KingJing1/babyreader.git
cd babyreader
./scripts/build.shThe script compiles the native binary, bundles the app, and installs to ~/Applications/BabyReader.app. It registers with Launch Services and sets BabyReader as the default handler for .md, .txt, and .epub files.
To create a clean release zip:
./scripts/package_release.sh- EPUB reader — table-of-contents sidebar, continuous scrolling, embedded images, warm dark/light themes that actually feel warm
- Highlighting — select text to highlight; re-select to remove. Highlights persist across sessions and auto-save to
~/Documents/BabyReader/as Markdown - Native macOS chrome — transparent titlebar, left-side TOC toggle, zero-divider layout. Looks like it belongs on your Mac, not in a browser
- Font scaling & position memory — Cmd+/- zoom that works, and it remembers where you left off
Double-click any .md, .txt, or .epub file — BabyReader opens it in rendered reading view.

Web readers were supposed to be convenient. Instead they became a negotiation — with autoplay video, with cookie banners, with "sign in to continue reading." Even reader modes are bolted on as afterthoughts to interfaces optimized for engagement, not comprehension.
A dedicated reader is a statement about what reading is for.
-
Attention is the reading surface — every notification, every recommendation widget, every animated ad is a physical intrusion into the space where thought happens. A quiet room with one article is not minimalism for aesthetics. It is the minimum viable condition for actual reading.
-
The tool should disappear — good reading software has no personality of its own. It renders your words cleanly and then gets out of the way. No onboarding. No features to discover. No engagement metrics. Just the text.
-
Long-form reading deserves better than a browser tab — whether it's a 2,000-word article or a full-length book, serious reading deserves serious typography, in one sitting, without your email loading behind it. The reading experience is part of the thinking.
-
Local is a value, not a limitation — files on disk don't expire. They don't require a subscription. They don't track what you lingered on. Ownership of your reading material should be as simple as ownership of a book.
