Conference rooms, equipment, boats, and even people can be reserved through LibreBooking, a self-hosted scheduler that keeps double bookings off the calendar. Schedules define bookable time slots with custom layouts and seasonal availability, while each resource carries its own minimum and maximum duration, buffer time, lead time, capacity, and optional approval step. Check-in and check-out can release unclaimed slots automatically, and blackout times close resources for maintenance. Quotas stack limits by hours or reservation count, credits meter peak and off-peak usage, and users can buy credits through Stripe or PayPal. Accessories such as projectors or chairs ride along with a booking under their own quantity limits. Groups carry application, group, resource, and schedule administrator roles, and custom attributes extend reservations, resources, and users with text, dropdown, date, or checkbox fields. Reports can be charted, exported to CSV, printed, or emailed, and public resources publish RSS and iCalendar feeds for Outlook and Thunderbird plus an embeddable calendar snippet. A tablet view beside a door shows live availability for on-the-spot booking, a monitor view fills lobby screens, and a Slack command starts a reservation. Sign-in options include LDAP, Active Directory, OAuth2, and SAML, and the REST JSON API automates bookings. Users can join waitlists, request reminder emails, and accept terms of service before booking, while six color themes restyle the interface.

MediaMTX sits between cameras and viewers as a self-hosted live media server, taking in video and audio streams over one protocol and handing them back out over another, so one IP camera feed can end up playing in a browser, a phone app, and a recording archive simultaneously. Publish with FFmpeg, GStreamer, OBS Studio, a browser, or a Raspberry Pi camera over RTSP, RTMP, SRT, WebRTC, Media-over-QUIC, HLS, MPEG-TS, or RTP, and read it back on any other protocol without a transcoding pipeline. Run dozens of camera feeds side by side, each on its own path, and keep every path available even while its publisher is offline. Record everything to disk in fMP4 or MPEG-TS as it streams, then play recordings back later through the same server instead of shipping files around. Authenticate publishers and viewers with built-in users, an external HTTP check, or JWT, and use the control API plus Prometheus metrics to wire the server into the rest of your monitoring stack. Forward streams to other servers, proxy cameras behind NAT, and fire hook commands whenever a client connects, publishes, or disconnects, so a doorbell camera can trigger a snapshot or an alert as it starts streaming. Reload the configuration while clients stay connected, and tune everything from the same mediamtx.yml file or environment variables, with no database or runtime dependencies to babysit.

Real-time alerts from your own infrastructure to your phone, with no Firebase, Pushover, or third-party push service in the path: Gotify is a simple, self-hosted notification server written in Go. The model is deliberately minimal: senders push messages with a single HTTP POST to the REST API, receivers subscribe over a WebSocket stream, and a clean React web UI manages the pieces. Senders are namespaced as "applications," each with its own token, so your backup script, Uptime Kuma, CI pipeline, and cron jobs each get an identity, an icon, and independently revocable credentials - centralized alerting from many services with per-source management. Messages carry a title, body, and priority level that maps to notification importance on the client. The official Android app (on both F-Droid and Google Play, notable for working entirely without Google Play Services) shows push notifications for new messages; the web UI itself supports Web Push in the browser; and gotify/cli pushes messages from shell scripts with one command. A server-side plugin system adds custom behavior, and the whole thing runs as a single small binary with SQLite by default - near-zero resource footprint. Because dozens of tools (and Apprise) speak Gotify natively, it slots in as the notification hub for an entire homelab or ops stack.

A video too large for Discord, a secret that should not live in a chat log, or a config file a headless server needs to fetch: MicroBin turns each into a short link with an animal name, served from your own machine. Paste text or code and it comes back with syntax highlighting, inline image and video embedding, and a QR code for moving it to a phone. Attach one file or several, then decide exactly who can see them: uploads can be public or private, editable or locked, set to expire on a schedule or to never expire. For sensitive material, server-side encryption and client-side end-to-end encryption keep contents unreadable without the password. Raw serving hands the plain bytes to curl, a browser, or another program, which makes the same box a tiny file endpoint for scripts and test rigs. A postbox mode lets people send you files and texts they cannot browse or delete afterwards, and a read-only mode with an uploader password turns the instance into a drop point with exactly one trusted sender. The admin console lists uploads and storage, and everything runs as one small binary backed by SQLite or a JSON file, comfortable in a few megabytes of memory.

Consolidate daily to-do lists, encrypted passwords, household spending, contacts, and family photo galleries into Personal Management System, a self-hosted private command center for everyday life. Individuals can organize recurring schedules and calendar milestones with proactive notification alerts so important appointments, vehicle servicing dates, and recurring bill renewals are never overlooked. Users can balance household budgets and track expenditure across custom spending categories, calculating monthly cash flow balances while monitoring debts owed to friends or family members. Privacy-conscious users can safeguard account credentials inside an encrypted password vault featuring quick-copy buttons and secondary lock protection for sensitive personal entries. Goal setters can track multi-step personal targets and link financial milestones directly to dedicated savings pools. Home organizers can catalog contacts, log travel destinations with mapped imagery, and maintain categorized notes containing voice memos, bookmarks, and reference materials. Collectors can sort family photos and video recordings into interactive masonry galleries with built-in lightbox previews and file download tools.

Workplace and Yammer's pattern on your own server, with GDPR compliance by construction rather than contract: HumHub is an open-source enterprise social network from Germany. Built in PHP on Yii2, it organizes everything around four concepts. Users get rich profiles with follows and interactions. Spaces are the structural unit - rooms for departments, projects, events, or clubs, with per-Space permissions, notification settings, and email summaries, and operators can auto-map users into the right Spaces. Content covers posts, wiki pages, photos and video, events, and tasks, with multi-level comments, versioning, archiving, moderation reporting, and filterable full-text search across everything. Modules make it a platform: roughly 80 install-and-activate extensions including Calendar, Wiki, Polls, Tasks, Gallery, News, direct-message Mail, OnlyOffice document editing, Advanced LDAP, SAML and JWT SSO, a RESTful API, mass user import, Translation Manager, and a Theme Builder with custom pages - every one optional and toggleable at runtime. That module economy is why HumHub serves such varied deployments: corporate intranets, city governments, universities, political parties, and nonprofits all configure the same core differently. Requirements are a plain LAMP stack - PHP 8.1+ and MySQL/MariaDB - making it one of the easiest community platforms to operate long-term.

When a query crosses its threshold, Nightingale, a self-hosted alerting engine, decides who hears about it and how, without moving data out of the stores you already run. Rules use PromQL, log queries, or SQL against Prometheus, VictoriaMetrics, Elasticsearch, Loki, ClickHouse, MySQL, or PostgreSQL, graded S1, S2, or S3 with a for-duration that absorbs brief spikes. Existing Prometheus alert rules import from YAML. Business groups give each team its own rules and dashboards, and sign-in works through OIDC, OAuth2, LDAP, or CAS. Once a rule fires, mute rules silence the noise, subscriptions add recipients, and event pipelines rewrite labels or route conditionally. Delivery reaches Slack, PagerDuty, Discord, Telegram, Jira, email, DingTalk, Feishu, WeCom, SMS, and voice calls, plus HTTP webhooks and scripts for anything else. Evaluation records, active and historical events, and notification results show what happened at each step. If an alert misbehaves, the built-in AI agent explains why it fired or never arrived, and it drafts rules, dashboards, and mutes from plain-language requests. Claude Code, Cursor, and other MCP clients can query alerts and manage alerting through /mcp, read-only by default and bound by the caller's own permissions. At remote sites, n9e-edge keeps evaluating and notifying when the link to the center drops.

Every scan and PDF you drop into Teedy becomes searchable text in a self-hosted document archive, filed by nested tags instead of folders. OCR reads images in more than twenty languages, and the search box offers suggestions and highlights matches, even inside ODT, DOCX, and PPTX files. Video files are supported as well. Each record carries Dublin Core fields plus custom metadata of your own design, with comments and earlier file versions attached. When a document needs a second pair of eyes, workflow steps with assigned reviewers move it along in order until someone signs off. Pull in EML emails, let the server poll an inbox, or point the bulk importer at a whole folder, and incoming paperwork needs no manual filing. Share a single document through a public link, or keep it behind user and group permissions with a storage quota for each person. LDAP and two-factor authentication guard sign-in, 256-bit AES encryption protects stored files, and an audit log records who changed what. Webhooks alert other services, a documented REST API lets scripts take part, and an Android client carries the archive on a phone.

Decisions that scatter across email threads and chat scrollback get one home in Loomio, where a group discusses a question, votes, and publishes what it decided. Every decision starts as a thread with context, comments, @mentions, reactions, tags, and attachments, and tasks inside it carry assignees and emailed due-date reminders. Proposals ask for a defined response plus an optional written reason, using sense check, advice, consent, or consensus templates. Polls handle simple choices, scores, dot voting, ranked choice, meeting-time availability, and multi-winner STV elections. Coordinators set a participation quorum, require a vote share, weight votes, limit voting to appointed delegates, or hide results until close with anonymous voting. Groups nest subgroups, pick Open, Closed, or Secret visibility, and admit members freely, by request, or by invitation. People reply to discussion emails and catch up through a daily digest, and webhook integrations post invitations and outcomes to Slack, Discord, Microsoft Teams, Matrix, and Mattermost. Published outcomes stay searchable, and groups export CSV, HTML, or JSON and print threads to PDF. Comments translate on request, the interface is available in 24 languages, and a user API, server API, and webhooks connect other tools.

Datasette turns a database into an interactive website and JSON API, so anyone can browse, filter, and query the data without a custom backend. Point it at SQLite files and each table gets a page with sortable columns, per-column filters, full-text search where it is enabled, and facets that tally the values in a column, including array and date columns, with suggested facets surfaced automatically. Rows have their own URLs, foreign keys become links, and a row that other tables reference links to a filtered list of those records. A "View and edit SQL" link turns whatever filters you applied into an editable query, and visitors with permission can run read-only SQL with named parameters. Useful queries save as canned queries with their own URLs, and writable canned queries add forms that insert or update rows. Every page comes as JSON and as streaming CSV. A metadata file adds titles, licenses, sources, column descriptions, units, default sort orders, and hidden tables. Access rules can apply to the whole instance or a single database, table, or query. Plugins add charts, maps for latitude and longitude columns, Atom feeds, GitHub sign-in, and custom output formats. Custom templates, CSS, and static files carry your branding. SpatiaLite support adds geospatial queries, and datasette publish deploys to Google Cloud Run, Heroku, Vercel, or Fly.

Kurrier unifies email, calendars, contacts, and file storage in a single web interface that connects to any email provider you already use. The Next.js frontend with Nitro API worker deploys via Docker Compose on PostgreSQL and Redis, delivering a cohesive workspace where IMAP/SMTP mailboxes from Gmail, Outlook, or corporate servers sit alongside transactional providers like AWS SES, SendGrid, Mailgun, and Postmark. Automatic inbox building handles threads, attachments, sent items, and deletion sync through persistent background polling. The CalDAV backend enables full two-way calendar synchronization with iOS, macOS, Android via DAVx5, and Thunderbird, supporting event invitations, RSVP processing through the inbox, timezone-aware scheduling, and contact-aware attendee linking. CardDAV contacts sync bidirectionally across all devices with unified name, avatar, and email resolution. Kurrier Drive provides integrated file storage through WebDAV locally or S3-compatible backends for cloud storage. Multiple identities and domains let you manage several email accounts from different providers in one interface, with fast local search indexing subjects, senders, and content without dependency on external APIs. The API-first architecture exposes clean endpoints for automation and custom integrations.

For teams that answer customers by email, UVdesk is a free, self-hosted helpdesk that keeps every conversation in one shared queue. Customers have three ways in: a connected mailbox, the support portal, or a public ticket link that opens a conversation without a login. Gmail, Yahoo, Outlook, or any IMAP mailbox can feed the queue, with no limit on how many. Agents work in a threaded ticket view, where they reply, forward to a colleague, leave private notes, add collaborators, and pin important messages. Saved replies answer repeat questions, and prepared responses set a status, tag, priority, or assignment from the ticket footer. Administrators route work through groups and teams, and agent privileges decide which tickets each person may see. Workflows run events, conditions, and actions in the background, while spam settings reject senders by address, domain, or IP. A knowledge base of folders, categories, and articles, with revision history and related articles, lets customers find answers without writing in. Customers can rate the support they received, and the Kudos report lists those ratings by agent, group, team, type, priority, customer, or source. Portal branding covers a logo, brand colors, a tag line, and custom CSS and JavaScript. The community edition places no cap on agents, groups, teams, customers, or tickets.

tirreno watches what accounts actually do inside your product, then surfaces the ones that look like account takeover, credential stuffing, fake signups, or insider abuse. Your backend reports events such as logins, registrations, page views, searches, email changes, and field edits through an SDK or one HTTP call, and a scheduled job turns them into per-user context: devices, IP addresses, sessions, and connected identities. Preset rules cover account takeover, credential stuffing, content spam, bot detection, multi-accounting, promo abuse, dormant accounts, API protection, and high-risk regions, and you can add rules of your own. Each rule adds to a risk score, and thresholds decide whether a user is flagged for manual review or suspended automatically. The review queue lists who needs a look, and the single user view shows behaviour patterns, risk scores, connected identities, and an activity timeline. A field audit trail records what changed and when, which supports compliance reviews, while the logbook lists every API request the instance received. Your application can ask a blacklist endpoint whether a user or IP should be blocked before it responds. An optional IP enrichment pack adds geolocation, ISP, and VPN or proxy detection. All event data stays on your own server. 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.

Curating digital comic archives, serialized manga, and electronic book libraries becomes effortless with Stump, a high-performance reading server that streams media collections over OPDS protocols directly to web browsers and e-reader hardware. Readers can organize extensive collections across CBZ, CBR, PDF, and EPUB formats, utilizing automated scanners that extract embedded ComicInfo XML and Calibre metadata tags. The built-in web reader renders high-resolution comic spreads, continuous vertical webtoon scrolls, and reflowable text with customizable color themes, font scaling, and reading direction toggles. Users can highlight passages, create persistent notes inside EPUB editions, and organize complex franchises into custom reading lists, oneshots, and smart filter collections. Bi-directional synchronization integrates with Kobo and KOReader hardware devices, maintaining page progression and bookmark states across handhelds and desktop sessions. Server administrators can configure multi-user access rules, enforce age restriction thresholds, and provision user-scoped API tokens for automated script pipelines and third-party companion tools. GraphQL and REST endpoints expose the entire catalog structure, allowing media collectors to integrate external metadata scrapers and trigger background library indexing tasks.

Keep every ticket tied to the servers, applications, and contracts it affects with iTop, an IT service management platform that joins a configuration management database (CMDB) to a helpdesk. Agents work user requests, incidents, problems, known errors, and changes through ITIL-style life cycles, and SLA targets for time to own and time to resolve move a ticket to an escalated status when a deadline passes. The CMDB models infrastructure, virtualization, end-user devices, software, and business applications, and its impact analysis graph shows what a failing server would take down. A service catalog of services and subcategories, backed by customer and provider contracts, feeds a user portal where employees and customers submit requests from a mosaic, tree, or list, follow progress, add comments and attachments, and reopen resolved tickets. Administrators bulk-load inventory from CSV, run consistency audits to catch data-quality problems, synchronize records from external sources, and connect other tools through REST web services. Sign-in works with local accounts, LDAP, or CAS, with optional two-factor authentication through authenticator apps, email codes, or recovery codes, and the console offers dark, high-contrast, and color-blind-friendly themes.

Your bank balance is only part of what you own, and MoneyMatter adds the rest: cash accounts, brokerage portfolios, cars, loans, and private deals roll into one net worth figure in your base currency. Add transactions by hand, import CSV, OFX, QFX, YNAB, Wallet, or Microsoft Money files, or let an AI model you provide parse a statement, while Monobank, SimpleFIN, Lunch Flow, and Walutomat connections sync accounts automatically. Each transaction can carry categories, tags, payees, notes, attachments, and splits, transfers and refunds link to their counterparts, and automation rules tidy new entries. Envelope-style budgets assign money to lines with Assigned, Activity, and Available columns and rollover rules, savings goals read progress from account balances, subscriptions and bills send reminders, and loans show payoff projections. Stocks, ETFs, and crypto are priced daily, vehicles depreciate along a curve, and a FIRE planner estimates years to Lean, Regular, Fat, Barista, and Coast FIRE. A customizable dashboard, cash flow, money flow, net worth history, trends comparison, and pivot table chart the results. Share accounts with a household member, export JSON, CSV, or XLSX, back up everything, or connect Claude, ChatGPT, or Claude Code through the built-in MCP server.

A clean alternative to n8n and Zapier that puts AI-native workflows front and center, Fynt is the MIT-licensed workflow automation platform where you drag nodes onto a React Flow canvas, wire them together with typed connections, and let a distributed BullMQ engine execute them — with every step streamed live to your browser over WebSockets so you never wonder what happened inside a run. The node library spans triggers (manual, webhook, cron scheduling), AI providers (OpenAI, Anthropic, and Gemini with structured output parsing), service integrations (GitHub webhooks, Notion databases, Slack channels, Discord bots, arbitrary HTTP endpoints), logic gates (conditional branching, filtering, data transformation), and utility nodes (delay, logging, payload mapping). The execution architecture separates concerns across three services: a Next.js 16 web application serving the React 19 workflow builder and tRPC API, a BullMQ worker processing jobs with node-level retries and checkpointing for crash-safe execution, and a dedicated WebSocket relay server broadcasting real-time run events via Redis Pub/Sub. All stored credentials are encrypted at rest using AES-256-GCM with per-credential initialization vectors. The full-stack deploys as a single Docker Compose stack (web, worker, realtime, PostgreSQL, Redis) or individually via pnpm workspaces in a Turborepo monorepo. Authentication is handled through better-auth with configurable OAuth providers.

Bring your own API keys and work with OpenAI GPT models, Anthropic Claude, Google Gemini, Mistral, DeepSeek, Grok, Azure endpoints, and local models in one organized workspace: TypingMind is a unified chat frontend for large language models, replacing a browser tab per provider. Parallel chat sends the same prompt to multiple models and compares answers side by side, and models can be switched mid-conversation. A prompt library stores reusable, tagged prompts with variables, and the AI Agents system builds specialized assistants that bundle a base model, custom instructions, assigned plugins, and uploaded knowledge files for RAG. Plugins extend every connected model with web search, image generation (DALL-E, Stable Diffusion), Deep Research, URL reading via Firecrawl, and Zapier automation - plus MCP server integrations for Notion, Atlassian, and other external tools, and a JavaScript extension API for custom behavior. Chats store locally by default with optional sync. Self-hosting puts the interface on your own domain and, for teams, adds branding, member access limits, and shared prompt and agent libraries.
