Trilium Notes — TypeScript/Windows, Linux, MacOS, and Website

Where most note apps store everything as flat text files, this one commits to SQLite instead. That choice buys what plain files struggle with: cloning a single note into many places in the tree, and staying fast past 100,000 notes.

weathr — Rust/Windows, Linux, MacOS, and FreeBSD

Most terminal weather tools dump a static block of numbers and call it done. weathr renders the forecast as live ASCII instead, animating rain, snow, thunderstorms, and a day-night sun-and-moon cycle in full truecolor without leaving the shell.

Oh My PPT — TypeScript/Windows, MacOS, and Website

Most AI deck tools hand you a rigid file that resists every later tweak. This one renders slides as plain HTML, CSS, and JS, driven by a local or cloud model, so the result stays fully editable and exports anywhere.

Tabia — JavaScript/Website

Browser-local chess opening trainer, repertoire trainers keep your opening prep, and your review schedule, inside an account-gated database you don't control. tabia runs as a static site with zero backend instead, so every line you build lives entirely in your own browser.

openDAW — TypeScript/Website

A full digital audio workstation, recording, MIDI, synthesis, effects, that runs entirely in a browser tab. It deliberately avoids external frameworks, leaning on WebAssembly for the DSP and the Origin Private File System to hold your samples like a native app would.

Beaver Notes — JavaScript/Windows, GNU/Linux, and MacOS

Capturing a PDF, a freehand sketch, a linked idea, and a live LaTeX equation usually means four different apps. Beaver folds them into one keyboard-driven editor where your files stay local and you pick which cloud, if any, handles sync.

Instafel — Java/Android, and Website

Staying on Instagram's bleeding-edge Alpha usually means the plain stock client, with no room to customize. This modular suite patches its own features directly into those Alpha builds, splitting the fetch, patch, and update work across separate, focused subprojects.

WebToApp — Kotlin/Android

Most URL-to-APK tools stop at wrapping a WebView. This one packages and signs full Android apps on your phone, no remote build queue, then runs Node.js, PHP, Python, Go, and WordPress as native binaries from app storage.

Beatsync — TypeScript/Website

A Spotify Jam keeps a shared queue in sync, but every phone still plays on its own slightly-off clock. Beatsync syncs the audio itself with NTP-style timing, turning a roomful of browsers into one phase-aligned speaker array, joined by a shared room code.

DroidSpaces — Kotlin/Android, and Linux

Running real Linux on Android has meant chroots without isolation, PRoot's PTRACE overhead, or Docker in Termux that Android kills on a whim. This takes real root privileges instead, so systemd and GPU access work and containers survive uninstall.

Twine — Kotlin/Android, iOS, MacOS, and Desktop

Hand it any website homepage and it hunts down the feed for you, then tints its whole ambient palette from whatever you're reading. One Compose Multiplatform codebase carries that same reading experience across Android, iOS, desktop, and Mac.

Awesome Android TV FOSS Apps — Markdown/Android

Most FOSS app directories assume a touchscreen phone. This index only catalogs apps suited to the remote-driven Android TV interface, and it labels each entry with the compatibility caveats that decide whether something is actually usable from the couch.

MonoGram — Java/Android

Telegram's own Android app keeps folding in NFT pushes, gifts, and crypto promos that have nothing to do with messaging. This client is written from scratch rather than forked, drops that cruft, and ships a Libre build that runs notifications through UnifiedPush instead of Firebase.

KoalaSync — Javascript/Chrome, and FireFox

Built for remote movie nights without the registration wall or tracking that commercial watch party tools bundle in. Playback stays synced across peers through a relay that holds nothing in persistent storage and purges the room the moment you leave.

BookLike — TypeScript/Website

Long web articles usually mean endless scrolling through cluttered pages. This extension reflows any article into paginated, book-like spreads you flip through, and compiles a clean EPUB on-device when you want to keep reading offline.

LibreTorrent — Java/Android

Most Android torrent apps stick to the classic BitTorrent protocol. LibreTorrent, built on libtorrent4j, handles both BitTorrent 2.0 and WebTorrent, and adds sequential streaming, RSS auto-downloading, and tracker proxying in one client that also runs on Android TV.

FOSS Browser — Java/Android

A privacy browser that keeps separate rules for every site: adblock, JavaScript, cookies, and fingerprint protection are saved per domain, not flipped globally. The whole UI sits at the bottom for one-hand use, with close to twenty gestures mapped across the toolbar.

Bonjourr — TypeScript/Chromium, and Firefox

Most new-tab replacements stop at a nicer wallpaper. This iOS inspired startpage turns the blank tab into a quiet dashboard: an analog clock, weather, a Pomodoro timer, and markdown notes, over a 4K backdrop that shifts with the time of day.

Tracking workouts in a notebook while logging meals in a separate app splits your routine across tools that don't sync. wger builds routines with automatic weight progression and logs meals against Open Food Facts, all from a server you run.

Mako — Kotlin/Android

Most launchers ship with analytics SDKs and cloud sync bolted on. This one skips both, built entirely in native Kotlin so every group, rename, and gesture stays local, with no network access required at all.
