Scheduling infrastructure, not just a booking page - Cal.com is the leading open-source scheduling platform. Share a link, attendees pick a slot, and real-time sync against Google Calendar, Outlook, and CalDAV prevents double-booking. Beyond the basics it covers team workflows: round-robin distribution, collective availability across multiple hosts, recurring meetings, and routing forms that ask bookers questions and send them to the right team member - the feature sales and support teams usually pay enterprise prices for. Paid bookings run through Stripe, video calls through the built-in Cal Video (Daily.co) or Zoom and Google Meet, and an app store connects 100+ tools including HubSpot, Zapier, and n8n. The API-first architecture with webhooks and embeds makes it practical to build scheduling into your own product, white-labeled with your domain and branding. Built on Next.js and Prisma over PostgreSQL, translated into 65+ languages, with the self-hostable community codebase maintained under an open-source license.

No spreadsheet has to track which service owns which port, because portracker discovers every service and port on your servers and keeps the list current from a self-hosted dashboard. Begin with a single port, shown with its owning service, its source (Docker or the host system), and its address, with internal container ports told apart from ports published to the host. Step back and ports gather into services: expandable cards carrying an icon, a health dot, and a port count, in list, grid, or table layouts, where a Why this status popover names the failing component and the rule that fired. Step back again and each server gets its own panel with hostname, OS, CPU, memory, and uptime, plus TrueNAS apps, VMs, and LXC containers once an API key is added. Step back once more and the whole fleet appears, because other portracker instances can be linked as peers, a VM's instance can be nested under its host, and every server can be searched at once. Along the way, rename services, hide the noisy ones, attach notes, act on a selection in bulk, or press Generate port for an unused number before deploying something new. Optional sign-in with a first-run setup wizard, an autoxpose link that shows public URLs and SSL status, light and dark themes, and keyboard shortcuts finish the picture.

Friday night, 1994: you are standing in the Action aisle deciding what the weekend looks like, except the shelves are stocked with your own library and the store lives in your browser. Halcyon Video rebuilds that ritual in 3D around your Jellyfin, Plex, or Emby server, turning libraries into aisles and genres into signed sections you can walk. Pick a case off the shelf and it comes up in your hand at true rental proportions; flip it over for the synopsis, cast, runtime, ratings, and a technical table read from the actual file. Seasons arrive as box sets, popular titles sit deeper on the shelf, and the clerk behind the counter searches by title, director, or genre and recommends from your catalog and watch history. Carry an armful to the checkout and she bags them in plastic that folds around the cases, receipt and all. A RomM connection opens a games department with platform-correct cartons and clamshells, while Jellyseerr requests appear as discovery cases you can order in-store. Drive it from the couch with a TV remote, gamepad, keyboard, or phone, or let attract mode tour the floor past the ceiling CRTs.

Neko Master watches every connection flowing through your Clash, Mihomo, or Surge gateway and turns the stream into a live map of devices, domains, countries, and proxy nodes, so questions that once needed packet captures get answered at a glance. The dashboard refreshes over WebSocket as traffic moves, charting upload and download trends across thirty minutes, one hour, or a full day. Domain views rank every host your network contacts by traffic and connection count, and IP views add ASN and geographic detail, so an unfamiliar endpoint explains itself instead of raising an alarm. Proxy statistics break traffic down per node and per rule, which makes a saturated exit, a misrouted application, or an underused subscription obvious in seconds. One panel watches several gateways at once: add OpenClash backends directly, or install the one-command agent on OpenWrt, Linux, or macOS machines beside remote gateways and let each agent report home. Because agents open the connection outward, gateways behind NAT still report in, and the panel never reaches into your network uninvited. History persists in SQLite by default, and busy networks can dual-write traffic statistics to ClickHouse for larger histories while configuration stays in SQLite. Token-based access control protects the dashboard, dark mode and an installable PWA keep it comfortable on a phone, and the interface switches between English and Chinese.

Scrob is your own private Letterboxd and Trakt: it syncs Jellyfin, Plex, and Emby libraries, tracks every movie and episode you watch, and keeps ratings and lists on your server. Connect Jellyfin, Plex, Emby, Nuvio, ARVIO, or Stremio and Scrob imports libraries, watched status, and playback progress, then pushes watched state and ratings back to keep every server aligned. Webhooks from Jellyfin, Plex, and Emby and the scrob-kodi addon mark items watched the moment playback finishes; a manual scrobble starts a live session from any title page. Rate titles on a ten point scale, score seasons separately, add reviews, and log repeat plays with their own dates. Personal lists stay private or open to other users on your instance, comments attach to titles, seasons, and episodes, and following users surfaces their ratings and activity. TMDB powers discovery: trending titles, genre and provider filters, release schedules, and search across people and collections merged with your library. Detail pages combine posters, cast, trailers, and your files' quality details, and one click sends a missing title to Radarr or Sonarr. Continue Watching and Next Up cards, a fifteen day episode calendar, and Pick a Movie or Pick a Show suggestions answer what to watch next. Trakt, Simkl, and MDBList sync moves history and ratings in both directions.

Somewhere between the shoebox and the inbox, Papra keeps receipts, warranties, and leases in a self-hosted archive you can actually search. Upload a photographed receipt and built-in OCR reads its text, so a search for the store name finds it later. Searches combine name:, content:, tag:, created:, and has: filters with AND, OR, NOT, and parentheses, and any query can be saved as a sidebar view. Tagging rules label uploads by name or content and can be applied to documents already stored. Optional AI auto-tagging works with a cloud provider or a local model such as Ollama. Custom properties add searchable typed fields such as text, number, date, yes or no, and select. Organizations keep a household's or a team's archive apart, with owner, admin, and member roles. Share links let outsiders open a document without an account, with optional passwords and expiry dates, and each link can be switched off. Forward an email to a generated address, or drop files into a watched folder, and documents arrive without opening the app; both are opt-in. Deleted files wait 30 days in the trash, and optional encryption protects stored files. Sign in with email, GitHub, Google, or a custom OAuth2 provider, and script the archive through the API, SDK, CLI, or webhooks. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Notes, tasks, and habits in one app, synced only to a server you run yourself. Notes are written in Markdown and render right in the list, so reading one costs no clicks. Tasks get a planned date and time, a duration, a checklist, and a timer. Weekly statistics show what got done and how long it took. Habits are measured by how overdue they are, not by an unbroken streak. A habit on a ten day interval that is two days late reads 120 percent. Charts track progress toward the target for today, this week, this month, this quarter, and this year. They also list the ten longest streaks and what you finish on each weekday. Categories and priorities span all three item types. Search reads note text and checklist items, not only titles. Filter by date, status, or how overdue a habit is, then sort with eleven keys. Pick from 26 themes in dark and light mode and 20 languages, with full keyboard and screen reader support. Import and export JSON, YAML, TSV, or Markdown, or bring in a Google Keep Takeout ZIP. Native apps for Windows, Linux, macOS, iOS, and Android sync with your server. The single-user Docker server also serves an OpenAPI spec, a Scalar UI, and a log page behind the same login.

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.

Windshift packs boards, sprints, roadmaps, test runs, time tracking, and a customer portal into one open-source tracker that replaces Jira on a server you control. Epics, stories, and sub-tasks form a hierarchy you can view as a board, list, tree, or map, and backlog items drag into dated sprints. The roadmap stretches across weeks, months, or quarters, and milestone pages show completion percentage with a status breakdown. Each workspace defines its own item types, custom fields, screens, statuses, priorities, workflows with conditions and approvals, and permissions, while JQL-style queries save as shared views. Event-driven rules update fields, notify people, and create work. Customers file requests through a public portal, and your team works them through queues with SLAs and approvals. Reusable test cases roll into test runs with success rates, and timers log billable and internal hours against projects and customers. GitHub, GitLab, Gitea, and Forgejo connections put branches and pull requests on the work item, and the importer brings over Jira projects, comments, attachments, and worklogs. A knowledge base and an asset register keep documentation and inventory next to the work. The interface speaks nine languages, including right-to-left Arabic, and sign-in supports OIDC single sign-on and passkeys.

Converting inbound chat conversations into closed revenue is what Deskcomm orchestrates through an open-source sales operating system with native AI agent routing and WhatsApp integration. Sales representatives monitor incoming customer inquiries across connected WhatsApp Web sessions and official WhatsApp Cloud API channels from a real-time shared inbox with multimodal attachment previews. Autonomous AI agents qualify incoming leads, extract contact parameters, parse customer objections, and book calendar appointments before escalating complex deal negotiations to human account executives. Commercial teams organize deal progression through interactive kanban pipeline boards, where drag-and-drop movements trigger automated follow-up sequences and dynamic message templates. The built-in knowledge retrieval studio ingests internal product documentation and FAQ catalogs, allowing AI attendants to cite verified organizational knowledge during client interactions. Multi-tenant access controls enforce strict data isolation between business units with granular role assignments for managers and support operators. Administrators monitor token consumption across OpenRouter and OpenAI models while synchronizing customer records with external platforms through Model Context Protocol servers and outbound Webhooks.

Build your own image and video sharing site, with public galleries, private albums, and embeddable links, on a server you control. Uploads arrive by drag and drop, clipboard paste, image URL, camera, ShareX, or API, in AVIF, JPEG, PNG, GIF, WebP, BMP, MOV, MP4, and WebM, and chunked transfers handle large files. Lossless JPEG handling fixes orientation and can strip EXIF data. Duplicate detection catches repeat uploads. Tags are created on the fly with autocomplete, camera models become tags automatically, and albums nest into sub-albums with covers, privacy levels, and passwords. Categories, search, and explore views help visitors find things; a bulk importer brings in folders of existing media. Each file gets viewer, direct, thumbnail, and medium links plus HTML, Markdown, and BBCode snippets with one-click copy, and oEmbed lets other sites preview a link. Roles split admin, manager, and user duties, profiles can be private, and two-factor authentication protects accounts. Files sit on local disk or S3-compatible storage, optionally served through a CDN URL. A dashboard tracks usage, color palettes and custom CSS and JavaScript restyle the site, and a single-profile mode suits a personal portfolio. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

PrivateBin shares text and files with true zero-knowledge encryption: the server stores only ciphertext it cannot decrypt because the key exists exclusively in the URL fragment that never reaches the server. With over 8,400 GitHub stars and 500,000+ Docker pulls, it has become the standard for privacy-respecting paste sharing where not even the hosting operator can read stored content. All encryption uses 256-bit AES in Galois Counter mode performed entirely client-side in the browser. Burn-after-reading mode destroys pastes on first view, while configurable expiration timers automatically purge content after periods ranging from five minutes to forever. Optional password protection adds a second encryption layer requiring recipients to enter a passphrase before decryption occurs. Discussion threads enable anonymous or nickname-based commenting on pastes with IP-based identicon avatars for visual identity. Markdown rendering with live preview formats pastes as styled HTML, and syntax highlighting through prettify.js supports dozens of programming languages across four color themes. File upload support enables sharing images, PDFs, and media files with in-browser preview. QR code generation converts paste URLs for mobile device transfer. Customizable templates include Bootstrap 5, classic Bootstrap CSS, and Darkstrap themes. Storage backends support filesystem, MySQL, PostgreSQL, SQLite, Amazon S3, and Google Cloud Storage. Deploy via Docker with the privatebin/nginx-fpm-alpine image on port 8080.

Hi.Events is an alternative to Eventbrite, Tickettailor, and Dice.fm, eliminating per-ticket platform fees entirely when self-hosted. Event organizers create fully brandable event pages supporting paid, free, donation, and tiered ticket types with recurring and multi-date scheduling, sold-out waitlists that automatically release tickets when spots open, and product add-ons with category organization. Stripe Connect integration processes payments directly to the organizer's bank account with instant payouts, while offline payment methods support cash and invoice scenarios. Promo codes offer fixed or percentage discounts with usage limits, expiry dates, and promo-gated hidden tickets for VIP access. QR code check-in enables fast door scanning with multiple check-in lists, scan logs, and real-time attendance tracking across entry points. Custom checkout questions collect attendee information beyond standard fields, with advanced search, filtering, CSV and XLSX export, full and partial refunds, and bulk attendee messaging. The analytics dashboard tracks daily sales, revenue, tax breakdowns, product performance, and promo code usage with exportable reports, while affiliate tracking assigns custom codes to promoters with tracked sales data. Multi-user roles control organizer permissions, automatic invoicing generates receipts, and the REST API ships with interactive OpenAPI documentation.

Artalk embeds a full commenting system into any webpage with three lines of JavaScript, packing multi-site management, social login, spam filtering, and Markdown rendering into a client that weighs roughly 40KB. One server instance manages comments for unlimited websites with complete data isolation between sites, eliminating the need for separate deployments per project. The framework-agnostic Vanilla JS client renders a complete comment interface with Markdown support, LaTeX mathematical formula rendering, image uploads, emoji packs compatible with OwO format, and automatic dark mode detection. An integrated admin dashboard accessible through the comment box provides comment moderation queues, IP banning, comment pinning, page-level statistics, and content management without direct database access. Social login authenticates commenters through GitHub, Google, Twitter, Discord, and additional OAuth providers, while captcha protection spans four backends: image captcha, Cloudflare Turnstile, Google reCAPTCHA, and hCaptcha. Spam filtering layers include Akismet integration, keyword block lists, and cloud moderation services that catch unwanted content before publication. Email notifications support SMTP, Aliyun DM, and Sendmail transports with customizable templates, and multi-channel push notifications extend to Telegram, Bark, and other messaging platforms. The OpenAPI-documented HTTP API enables programmatic comment management. Database flexibility covers SQLite, MySQL, PostgreSQL, and SQL Server. A plugin marketplace offers community extensions for custom behavior. Continuously maintained for over 8 years.

A trading journal you host yourself, Trade Journal rebuilds broker fills and statement exports into round-trip trades, a profit and loss calendar, and daily notes that show what actually works. Read-only sync covers more than twenty brokers and exchanges, including Alpaca, Binance, Coinbase, Kraken, and IBKR Flex. Statement import auto-detects TradingView, MetaTrader, NinjaTrader, Tradovate, and thinkorswim files, handles TradeZella and Tradervue CSV migrations, and maps columns for anything else. Trades can be matched first-in-first-out, last-in-first-out, or by weighted average, with partial fills, scale-ins, and futures multipliers handled. The dashboard offers gauges, cumulative and daily P&L, an Edge Score radar, and cards you can rearrange into named layouts, while Reports break results down by symbol, tag, mistake, playbook, weekday, and time of day. Each trade page charts entries and exits and can replay candles you load, with estimated MAE and MFE. Daily journal pages hold Markdown notes, templates, attachments, and voice dictation, and optional AI recaps use your own Anthropic or OpenAI key or a local Ollama model. Playbook checklists score rule adherence, a prop firm ledger tracks costs and payouts, and privacy mode masks every amount.

Web analytics tools ignore native mobile, desktop, and game apps; Aptabase was built for exactly those. If Firebase Analytics would force a privacy-policy footnote you don't want to write, this is the alternative - session-based metrics with no cookies, no IDFA or GAID, no device fingerprinting, and a daily-rotated salt that makes cross-day re-identification mathematically impossible. That design means GDPR, CCPA, and PECR compliance out of the box and "Data Not Collected" App Store privacy labels without ATT prompts. The SDK coverage is the widest in its category: eleven first-party libraries spanning Swift, Kotlin, Flutter, React Native, Tauri, Electron, .NET MAUI, NativeScript, Unity, Unreal Engine, and JavaScript for web - each MIT-licensed, following platform conventions, and accepting a custom host parameter that points at your instance. Integration is minutes: initialize with an app key, call trackEvent with optional properties, and the dashboard shows sessions, events, app versions, OS breakdowns, and country-level geography. The self-hosted stack is a .NET server over PostgreSQL for metadata and ClickHouse for high-volume event ingestion, giving cloud-parity features under an AGPL license. For indie iOS/Android apps, Electron and Tauri tools, and Unity or Unreal games, it replaces Firebase without the Google entanglement.

Unlike pull-request forges, Gerrit reviews every Git change as a series of patchsets, and nothing merges until the required approvals are in. Developers upload with a plain git push to a refs/for ref, adding push options for topics, hashtags, work-in-progress, or private changes. Each change gets a page listing reviewers, CCs, an attention set that flags who must act next, and submit requirements driven by labels such as Code-Review and Verified, with a quick approve button for the last missing vote. Side-by-side diffs with syntax highlighting take inline comments written in Markdown, saved as drafts and published together. A Checks tab shows CI runs reported by plugins, and integrations reach Jenkins, GitHub Actions, Zuul, and webhooks. Access rights attach to groups and branch patterns, including regular expressions, and inherit from parent projects and All-Projects. Sign-in works with LDAP, OAuth, OpenID, or HTTP single sign-on, and SAML through a plugin. A query language filters changes by status, owner, reviewer, label, file path, and reviewer count. Projects pick a submit strategy: merge if necessary, fast forward only, rebase if necessary, rebase always, merge always, or cherry pick. A REST API, SSH commands, and a plugin system extend the server, and an optional Review Agent chat panel can summarize a change once an AI provider plugin is installed.

While ordinary chatbots sit idle between prompts, Agenvoy runs around the clock on your own machine, turning one-sentence requests into finished research, files, and reports. Say what you need once and it builds the missing tool itself, tests that tool inside a sandbox, saves it, and reaches for it again the next time a similar job appears. Recurring work becomes a schedule in plain words; a morning briefing, a watched folder, or a weekly report then runs unattended, and a long task interrupted mid-run resumes from its checkpoint instead of starting over. Ask questions about your own files and it searches them like a private archive, transcribing audio and video into text it can quote back to you. Each task is routed to the model tier that fits it, a light model for lookups and a heavy one for hard reasoning, across subscription logins, API keys from eleven providers, or a local Ollama that never phones home. Commands run in a sandbox with the network off until you approve a call, sensitive paths ask before they open, and credentials wait in the system keychain instead of the chat history. You drive it from the terminal, the browser dashboard, or Telegram and Discord when you are away from the desk, and it lends its sandboxed tools to Claude Code and Codex over MCP.
