CodeX Docs
Writing docs should feel like editing a modern document, not wrangling Markdown files - CodeX Docs delivers that on Editor.js, the block-styled editor its CodeX team builds and thousands of products use. Content is composed from clean blocks (headings, lists, code, images, embeds) with a UI that reads well on both desktop and mobile, and pages render statically with human-readable, SEO-friendly URLs. Structure is free-form: pages nest to any depth, so a flat FAQ and a deep product manual coexist in one instance, and the UI tunes to fit - collapse sections, hide the sidebar. The operational footprint is deliberately tiny. No database is required: the default driver persists to a local folder, with MongoDB available when you want it, and the whole app configures through one YAML file (overridable with APP_CONFIG_ environment variables) covering title, start page, auth password, and JWT secret. Editing mode sits behind password authentication. Thoughtful extras are wired in: readers can report misprints straight to your Telegram or Slack, Hawk error tracking catches frontend and backend exceptions, and Yandex Metrica analytics is a one-line config. A ready-made Helm chart covers Kubernetes. Written in TypeScript.

Radicale
Calendars, to-do lists, journal entries, and contacts, synced over the open CalDAV and CardDAV standards nearly every client already speaks: Radicale is a small pure-Python server that works with Thunderbird, DAVx5 on Android, Apple Calendar and Contacts, GNOME, and many more. Its defining design choice is radical simplicity: there is no database. Events live as plain .ics files and contacts as .vcf files in an ordinary folder structure, which makes backup a copy command, migration a move, and disaster recovery a matter of reading text files. The server works out of the box with no complicated setup, then grows as needed: flexible authentication (htpasswd files among other methods), per-collection authorization rules, TLS-secured connections, and a plugin system for extending storage, auth, and rights handling. Built-in limits on parallel connections, file sizes, and failed authentication attempts harden it for network exposure behind a reverse proxy. A bundled web interface handles creating and managing calendars and address books - useful since many clients cannot create collections themselves. Maintained since 2011 with 140+ contributors, GPLv3-licensed, and light enough to run on the smallest VPS or a Raspberry Pi.
Gotenberg
Send a document, receive a PDF: Gotenberg is a Docker-based, stateless HTTP conversion API trusted in production by thousands of companies and adopted by notable open-source projects. Send files as multipart/form-data, get a PDF back; Chromium, LibreOffice, and fonts are the container's problem, not yours. Headless Chromium handles URLs, HTML templates, and Markdown with pixel-perfect browser rendering: it executes JavaScript, loads web fonts, waits for network idle, a JS expression, or a DOM selector before rendering SPAs, and accepts injected cookies and HTTP headers for authenticated pages. LibreOffice converts 100+ office formats - .docx, .xlsx, .pptx, and legacy formats - with page-range extraction and PDF/A archival conformance. Built-in PDF engines round out the pipeline in every image variant: merge, split, rotate, flatten, encrypt, watermark, stamp, read/write metadata and bookmarks, plus Factur-X/ZUGFeRD e-invoicing and PDF/UA accessibility compliance. Screenshots of URLs and HTML come from the same endpoints. Zero-transfer pipelines stream files directly between S3, MinIO, or GCS presigned URLs and Gotenberg, bypassing your application entirely, and webhooks enable async processing. Statelessness means horizontal scaling is trivial - run as many replicas as your conversion volume demands. Three image variants (full, Chromium-only, LibreOffice-only) trim the footprint to what you actually use.

Muse
"A highly-opinionated midwestern self-hosted Discord music bot that doesn't suck," per its own README - Muse is built for servers the size of you, your friends, and your friends' friends. It exists because the big public music bots kept getting shut down or paywalled, and self-hosting yours means nobody can take it away. Written in TypeScript on discord.js, it joins voice channels and plays audio resolved from YouTube via yt-dlp, and given optional Spotify API credentials it auto-converts Spotify tracks, albums, artists, and entire playlists to playable equivalents. The playback details show real care: seeking within songs and videos, livestream support, local caching so repeated plays start instantly, volume normalization across tracks, and configurable volume controls including optional ducking that lowers music when people speak. SponsorBlock integration can skip non-music segments automatically. Users save favorite queries as reusable shortcuts, and one Muse instance serves multiple guilds simultaneously - one deployment for all your communities. Configuration is three environment variables (Discord token, YouTube API key, optional Spotify pair) and the personality is free: there is no vote-to-skip, because "this is anarchy, not a democracy," and the bot remains a loyal Green Bay Packers fan. MIT-licensed and easily extendable.
Isso
Named from the German "Ich schrei sonst" - roughly "or I'll scream" - Isso is a lightweight Python/JavaScript commenting server, a drop-in Disqus replacement for people who noticed what Disqus does to reader privacy and page load times. The design premise is printed right in the docs: comments are not Big Data. So the backend is a single SQLite file rather than a database cluster, and the entire client is one embeddable JavaScript file - 65 kB, 20 kB gzipped - that you drop into any static site, blog, or CMS. Commenters write in Markdown, need no account, and can edit or delete their own comments within a configurable window (15 minutes by default). Spam control comes from an optional moderation queue: held comments stay invisible until you activate them via an admin interface or email notification links. Migration is a first-class feature, with importers for Disqus and WordPress exports, so years of existing threads move over intact. Because everything is server-rendered from your own instance, no third party tracks your readers, and real-world switchers report smaller pages and faster loads than the Disqus embed. MIT-licensed, running since 2012.
Fireshare
The moment after ShadowPlay saves a great clip is what Fireshare was built for: your friends see it now, not after a YouTube upload, processing queue, and platform terms review. Drop videos into a watched folder and this Flask/React application generates a unique shareable URL for each one, complete with Open Graph metadata - so pasting the link into Discord, Twitter, or Slack produces a proper embed with title, description, and video thumbnail instead of a raw URL. Viewers need no account and no app. Visibility is per-file: public (browseable on your feed), private (unlisted, reachable only by direct link), or password protected. For game clips specifically, Fireshare organizes automatically - clips sort by game with cover art pulled from SteamGridDB, no manual tagging - while tags and full-library search cover everything else. Optional transcoding (CPU or GPU) creates lower-quality renditions so viewers on weak connections get automatic quality adaptation, and video cropping trims clips in place. The extras round out a genuinely finished tool: view counters, timestamped share links, a shuffle button, restrictable uploads, Discord notifications for new videos, an RSS feed of the public feed, mobile support, and LDAP for multi-user setups. No storage limits, no watermarks, no platform deciding what stays up. GPL-licensed.
Blender
Whip up a 3D masterpiece, animate your own indie flick, or craft virtual worlds that defy reality with Blender – the all-in-one, open-source 3D graphics wizard! This app is like a Swiss Army knife for your digital artistry needs, from 3D modeling to rendering faster than you can say 'Pixar'. Hosted on RepoCloud, it's like having a personal art studio in the cloud, minus the splattered paint. With a user-friendly desktop GUI, you'll feel like a digital Picasso in no time. Blender is souped-up with hardware acceleration, making your desktop experience smoother than a well-oiled robot. While it doesn't roll out the red carpet for GPU rendering straight away, it's still a party on multiple architectures. Just a heads-up for the Arm aficionados: it's best to avoid /dev/dri for now – Blender's a bit picky with the OpenGL ES version there. But hey, that's just a small bump on the road to 3D glory!
SimpleTorrent
Get ready to turbocharge your torrenting experience with SimpleTorrent, the self-hosted torrent maestro that lets you kick back while your torrents do the hustle. Crafted with the magic of Go (golang), this nifty app transforms your server into a torrent-fetching powerhouse, snagging files and lining them up for your streaming pleasure or HTTP retrieval. Fancy a bit of control? You got it! Pick and choose individual files, command an external app to celebrate task completion, and enforce a seeding etiquette to say 'stop' when you've shared enough. But wait, there's more! Throttle those speeds to avoid hogging the bandwidth and dive into the nitty-gritty of transfer stats with a web UI that's slicker than a greased otter. Real-time updates? Check. Mobile-friendly? You bet. A content server that's faster than a caffeinated cheetah? Absolutely. And with IPv6 readiness, a fresh torrent engine from anacrolix/torrent, and extra goodies like a torrent watcher, K8s/docker health-checks, bonus trackers, and a magnet protocol handler, SimpleTorrent hosted on RepoCloud is like having your very own torrent butler – all at a price that won't plunder your coin purse!
Radarr
The movie half of the *arr stack: Radarr is a .NET collection manager that automates acquiring films for Usenet and BitTorrent users the way Sonarr does for TV. Add a movie once and Radarr handles the rest: it monitors indexers and RSS feeds, grabs a matching release the moment one appears, sends it to SABnzbd, NZBGet, qBittorrent, Deluge, Transmission, rTorrent, or another connected download client, then imports, sorts, and renames the file into your library structure. Quality profiles are the control surface - define allowed resolutions and a cutoff, and Radarr keeps upgrading files automatically, replacing a DVD rip when a Blu-ray release lands. Custom formats go further, scoring releases by codec, HDR metadata, release group, streaming source, or arbitrary regex so the copy you want always wins the pick. Failed downloads retry with another release automatically; a manual search shows every candidate and explains why one was skipped. Release parsing recognizes director's cuts, special editions, AKA titles, and hardcoded subs. Plex and Kodi integration handles notifications, library refreshes, and metadata like posters, trailers, and subtitles, and a calendar view tracks upcoming releases. It pairs naturally with Jellyseerr for request management and shares its API conventions with the whole *arr ecosystem.
MeTube
Introducing MeTube: the browser's new best friend for video aficionados who prefer a click to a command line! Imagine a world where the mystical powers of youtube-dl are harnessed in a sleek, web-based chariot, ready to whisk away your favorite videos from YouTube and a cornucopia of other video realms, all with the ease of a single click.

Get ready to click, download, and dazzle with MeTube on RepoCloud!
PocketBase
An entire backend in a single Go executable: PocketBase embeds SQLite with realtime subscriptions, authentication and user management, file storage, and an admin dashboard, all behind a REST-ish API. SQLite runs in WAL mode, which outperforms client-server databases for the read-heavy workloads typical of small and mid-sized apps. Authentication supports email/password, one-time passwords, and 15+ OAuth2 providers including Google, Apple, and GitHub, with stateless tokens. Clients subscribe to record changes over server-sent events, and official JavaScript and Dart SDKs cover web, mobile, and Flutter frontends. Collections, rules, and API access permissions are managed visually in the admin UI. When you need custom logic, extend it with JavaScript hooks running in the embedded JS VM of the prebuilt binary, or import PocketBase as a Go library and compile custom business logic into your own single-file backend. File storage attaches uploads to records with thumbnail generation for images and optional S3-compatible external storage. All state lives in one pb_data directory, so backup is a directory copy and upgrade is replacing a binary - one of the lowest-maintenance backends you can run. The contrast with Firebase is the point: where usage-based pricing scales with reads, writes, and bandwidth, PocketBase runs the entire backend at flat hosting cost, and the data is a plain SQLite file you can copy anywhere. MIT-licensed.
AnonUpload
Introducing AnonUpload: the ninja of file-sharing apps that lets you sneakily share files without leaving a digital footprint. No databases, no nosy tracking – just pure, unadulterated privacy.

And size? Pfft, it laughs in the face of size! Whether you're uploading a hefty 10GB treasure trove or a tiny text file, it's all gravy. Plus, with a built-in 'anticipation enhancer' (some might call it a download timer), it adds a sprinkle of excitement to the downloading process. Host it on RepoCloud, and you'll be the file-sharing wizard with more tricks up your sleeve than a cost-conscious cloud host at a magic convention!

Just poke the endpoint, and voilà! Plus, with a few secret commands, you can mark messages as read, make them walk the plank one by one, or unleash a kraken to wipe them all out. Host it on RepoCloud, where the costs are as tiny as plankton compared to other cloud hosts, and you'll be sailing the high seas of email testing with a grin as wide as a whale's!
Oxigen
The social preview cards shown when links hit Twitter, LinkedIn, Slack, or Discord, generated on the fly: Oxigen is a small Go service for dynamic Open Graph images, no designer required per page. Instead of exporting static images per page, you compose a card once and drive it with parameters: title, author, website, logo, background image, and background dimming all arrive as URL query arguments, so your og:image meta tag simply points at the Oxigen endpoint with the page's own values substituted in. Every blog post, product page, and doc gets a branded, correctly sized preview generated on the fly. A built-in web UI covers interactive composition - tweak the text and imagery, watch the preview update, copy the resulting URL - while the same rendering path serves programmatic API use from static site generators, CMS templates, or build pipelines. Rendering is pure Go using the gg 2D graphics library, freetype fonts, and the imaging package, built on the kyoto framework by that project's author. Deployment is one stateless container on port 80 with no database and no external dependencies, so instances scale and restart freely.
