Rotki
Crypto portfolio tracking that inverts the SaaS model: rotki runs on your own machine, needs no email or account for the free tier, and keeps every wallet address, balance, transaction, and tax event in a local SQLCipher database encrypted with 256-bit AES. By default nothing passes through rotki-operated servers - a design choice that matters when cloud portfolio trackers concentrate exactly the identity-linked holdings data attackers want. Centralized exchanges (Kraken, Binance, Coinbase, Bitstamp, and more) connect through read-only API keys that can see but never withdraw; blockchain accounts cover Ethereum and its L2s, Bitcoin, Solana, Polkadot, and Kusama, with ENS resolution and your choice of RPC endpoint or your own node. rotki decodes on-chain transactions into readable events across major DeFi protocols - Aave, Uniswap, Compound, Curve, Lido - and generates profit-and- loss reports for tax season with customizable accounting settings, including FIFO, LIFO, and HIFO cost-basis methods, plus CSV imports for defunct exchanges. Optional premium sync is zero-knowledge, encrypting the database on-device before upload. AGPLv3-licensed and multiplatform, with a Docker package for server deployment.
PsiTransfer
Upload files, get a share link, let it expire: PsiTransfer is a self-hosted WeTransfer with no accounts, no logins, and no third-party cloud with size caps and metadata harvesting. The engineering focus is large files over imperfect networks. Uploads use the tus.io resumable protocol, so a dropped connection on a multi-gigabyte video resumes exactly where it stopped once you're back online; downloads support HTTP range headers for the same resilience, and everything streams, so file size is bounded by your disk rather than memory. Files organize into upload buckets with retention you control: expire after a set time (up to weeks) or after a one-time download, with automatic cleanup when links lapse. Recipients need nothing installed - they open the link, preview files in modal views, and grab everything as a zip or tar.gz archive with one click. Buckets can be password-protected (AES-encrypted download lists), and security-through-obscurity is done properly: bucket URLs use hashed UUID tokens and stored filenames are replaced with UUIDs. An optional admin page (enabled by setting an admin password) lists bucket information and storage. The Vue.js frontend ships under 100 KB gzipped and is fully responsive. Honest caveat from the author: no end-to-end payload encryption yet. BSD-licensed, Docker-ready.

No sign-up hoopla means more gab for everyone, and customization options that let you dress up your widget to match your website's snazzy suit. Host it on RepoCloud, and you'll be saving coins while your community thrives. Now, isn't that comment-worthy?
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.
Chatpad
Why should your chat history live on someone else's servers? Chatpad AI - a React/TypeScript front end for the OpenAI API, built on the Mantine component library - is designed around that question. Enter your own OpenAI API key and start chatting with GPT models; every conversation, prompt, and setting is stored locally in your browser via DexieJS over IndexedDB, with no tracking, no cookies, and no backend database at all. That architecture is the point - the Docker image is just Nginx serving static files, making it one of the lightest AI deployments in the catalog, and pay-per-token API pricing typically undercuts a ChatGPT Plus subscription for moderate use. The interface earns its "premium quality" tagline with the details: a persona selector that switches communication styles per conversation, a saved-prompts library for messages you reuse constantly, organized chat history, and full data export/import so conversations move between browsers or into backups as files you control. A JSON config file customizes defaults - models, API endpoints, UI options - without rebuilding the image. AGPL-licensed, with desktop builds available upstream. For teams that want ChatGPT's utility with a self-hosted, zero-telemetry footprint, Chatpad is the minimal, sane answer.
Flowise
Drag nodes onto a canvas and ship an LLM app: Flowise is an open-source visual builder for AI agents and LLM applications, written in Node.js on LangChain.js and licensed Apache-2.0. You assemble flows by dragging nodes onto a canvas: models, prompts, memory, vector stores, retrievers, and tools, then wire them together and test in the built-in chat panel. Three builder types cover increasing complexity: Assistant for simple RAG chat over uploaded files, Chatflow for single-agent systems with techniques like rerankers and Graph RAG, and Agentflow for multi-agent orchestration with branching, looping, shared flow state, and human-in-the-loop checkpoints. Over 100 integrations connect data sources, vector databases, and both proprietary and open-source models, plus MCP client and server nodes for standard tool interop. Finished flows are exposed as REST APIs, embedded chat widgets, or via JS and Python SDKs - each flow gets an endpoint the moment it is saved, removing the deployment gap between a working prototype and something your application can call. Execution logs, visual step debugging, and external log streaming trace behavior, while input moderation and rate limiting act as guardrails; RBAC, SSO, and workspaces cover team deployments. Self-hosting keeps prompts, encrypted credentials, and conversation data on your own instance, which matters when flows handle internal documents or customer data - and wiring a model, prompt, memory, and vector store on the canvas replaces the boilerplate a hand-coded LangChain project would need.
Easyshortener
Get ready to shrink those lengthy URLs down to fun-size with Easyshortener, the link-shortening maestro that's as easy on the eyes as it is on your digital security! Wave goodbye to the days of sprawling links with this multi-user marvel, where each user can tame their own wild web addresses from the comfort of a sleek administration panel. It's like having a Swiss Army knife for your links, but without the risk of nicking your fingers. And for those who like their online life as secure as Fort Knox, Easyshortener comes strapped with two-factor authentication – it's like a bouncer for your bits and bytes. Deploying this little gem is a breeze with Docker, so you can launch it into the web-o-sphere with the grace of a containerized cannonball. Plus, with registration and redirect tracking, you'll be the Sherlock Holmes of link management, and the option to enforce HTTPS is like putting your links in an armored van. Host it on RepoCloud, and you'll be the link-shortening hero you never knew you needed, at a price that keeps your wallet just as happy as your links!
Freshrss
Where Miniflux strips reading down, FreshRSS gives you knobs - the feature-rich pole of self-hosted RSS, comfortable with thousands of feeds. It's a multi-user PHP aggregator (host family and friends on one instance, with an anonymous reading mode) with the reading workflow refined over a decade: favorites, custom tags, powerful filter and search queries, three reading views, and statistics that reveal each site's publishing frequency - useful for pruning subscriptions. Two properties make it the standard choice. First, the Google Reader-compatible API (plus a Fever API) syncs with virtually every serious RSS client - Reeder, NetNewsWire, ReadYou, FeedMe, Fluent Reader - so your phone reads from your server. Second, native WebSub support means compatible sources (WordPress, Blogger, Medium, Friendica) push new articles instantly instead of waiting for polling. A 50+ extension ecosystem adds what truncated feeds omit - full-text content fetching, reading-time estimates, trending views, auto-unsubscribe for dead feeds - alongside community themes and custom CSS. OPML import/export keeps subscriptions portable, a CLI handles administration, and article sharing posts to many services. AGPL-licensed, running on SQLite, MySQL, or PostgreSQL. Feedly Pro's feature set, minus Feedly's subscription and its algorithms.
Grav
No database anywhere in the stack: Grav, the leading flat-file CMS, builds every page from a folder of Markdown and YAML on PHP, Symfony components, Twig templating, and Doctrine caching. That architecture is the whole argument: content is Git-versionable, rsync-able, and lock-in-free; pages render in well under 100ms without database round-trips; and backup means copying a directory. Content authors write Markdown (or plain HTML), configure with readable YAML, and define custom page structures via blueprint files that generate editing forms automatically. The optional Admin panel adds a polished editing layer: dashboard with site activity, page management with a syntax-highlighted editor and live preview, drag-and-drop media uploads, one-click plugin/theme updates, and normal/expert modes for form-based or raw YAML editing. The ecosystem runs deep - hundreds of open-source plugins and themes installed through the GPM package manager, with an event-hook architecture that gives plugins full control over the request lifecycle, and downloadable skeletons providing entire pre-built sites. Grav 2.0 modernizes the stack (PHP 8.3+, Symfony 7, Twig 3) and adds a first-party REST API, an MCP server for AI agents, and a SvelteKit single-page admin with real-time collaborative editing. Ideal for docs, blogs, and marketing sites. MIT-licensed.
OpenProject

Hop on over to RepoCloud and let OpenProject lift your team to cloud nine!
mCaptcha
The CAPTCHA bargain - annoy your users and feed their behavior to Google - gets replaced with economics by mCaptcha. Instead of image puzzles, it uses SHA256 proof-of-work: every visitor's browser silently solves a small computational challenge (via a WebAssembly library) before submitting a form. Humans never notice the milliseconds; bots hammering your site must burn more compute sending requests than your server spends answering them, which makes attacks more expensive than defense - the property that also makes mCaptcha genuine DoS protection, not just bot filtering. Written in Rust, the system is fully automated: difficulty scales with traffic, so challenges stay trivial in normal conditions and harden under attack. The privacy and accessibility wins are structural rather than promised: no tracking, no profiling, no user-pattern data collection, and no visual puzzles that exclude users with visual or cognitive impairments - the design was published in Communications of the ACM. Rate limiting is IP-independent, so users behind NATs, VPNs, or Tor get the same experience instead of endless challenge loops, and proofs resist replay attacks, neutering captcha farms. Migration is deliberately easy: the API is compatible with reCAPTCHA and hCaptcha, making it a drop-in replacement. AGPL-licensed core with proprietary-friendly client libraries.
Papercups
Companies with privacy and security concerns about piping customer conversations through Intercom or Zendesk run Papercups - open-source live customer chat. The stack is a deliberate strength: an Elixir/Phoenix API over PostgreSQL, with real-time messaging powered by Phoenix Channels and Presence - the same BEAM foundation trusted by Discord and PagerDuty for fault-tolerant, low-latency messaging. Customers see a customizable chat widget that embeds in any site as an HTML snippet, a React component, or even inside React Native apps, with configurable colors, greetings, and away messages. Your team sees a dashboard for managing conversations - close, assign, and prioritize - with Markdown and emoji in replies. The killer workflow is the reply-channel integration: connect Slack or Mattermost and every customer conversation becomes a synced thread your team answers without leaving the tool they already live in, with two-way message syncing handled by webhooks. Email and SMS channels extend intake beyond the widget, an analytics dashboard tracks communication patterns, and the Storytime feature adds real-time screen sharing to watch users navigate while you help them. A documented API supports fully custom chat UIs in Svelte, Flutter, or Vue. MIT-licensed and GDPR-conscious - customer data stays in your PostgreSQL.
Remmina
Get ready to teleport your desktop experience with Remmina, the Swiss Army knife of remote desktop clients! Perfect for the digital nomad or the midnight-oil-burning sysadmin, Remmina lets you juggle multiple remote machines like a circus performer, with a smorgasbord of network protocols at your fingertips - RDP, VNC, SPICE, you name it! Crafted with love in GTK, it's as comfy on a jumbotron as it is on a pocket-sized screen. Dive in at http://yourhost:3000/ or take the secure plunge via https://yourhost:3001/. And thanks to its Docker Baseimage KasmVNC heritage, you can toggle features like a light switch, customizing your remote control experience. Host it on RepoCloud, and you'll save enough to treat yourself to a fancy coffee - because who needs overpriced cloud hosting when you've got the open-source haven of RepoCloud?
Hasty Paste
Paste some text, hit save, share the link - Hasty Paste is a fast, minimal pastebin written in Python on the async Quart framework, named, by its author's own admission, "because you use it so fast without a care in the world." No accounts, no authentication, no friction - built for the everyday case of handing a debug log, config snippet, or stack trace to someone in tech support or a chat channel. Pastes get randomly generated IDs, with an optional "long" ID mode that makes brute-force URL guessing impractical, and expiry times ensure throwaway content actually gets thrown away. Optional Pygments syntax highlighting makes code readable, a dark theme spares your eyes, and the whole interface works without JavaScript - it renders in terminal browsers and under the strictest script blockers. Storage is a custom flat-file system (no database), caching runs internally or through Redis for busier instances, and a REST API plus the companion "Hastily Paste It" CLI script enable piping command output straight into a paste from the terminal. The Alpine-based Docker image is tiny, resource usage is minimal, and the license is AGPL.
Tolgee
Hold Alt/Option, click any string in your running app, and edit the translation in place: Tolgee is an open-source localization platform built the way developers wish translation worked - changes save straight to the platform with no hunting through JSON or PO files. In-context editing works even in production via the Tolgee Tools browser extension, which injects credentials without touching source code, so a client or colleague with zero coding skills can translate the product inside the product. The SDKs (React, Angular, Vue, Svelte, plus iOS and Android) extract context from each UI element and capture one-click screenshots, giving both human translators and machines the surrounding meaning that raw string files lose. Autonomous translation uses that context: new keys are instantly filled from translation memory or machine translation (DeepL, Google Translate, AWS Translate), with optional human review afterward - shipping no longer waits on a translation agency. A CLI handles import/export, a REST API covers automation, a Figma plugin bridges design, and an MCP server lets AI coding assistants search keys, create translations, and trigger machine translation without leaving the editor. Self-hosting this Crowdin/Phrase/Lokalise alternative keeps every string, screenshot, and API key on your infrastructure.
