Bookshelf turns a folder of EPUBs and PDFs you already own into a private library you can browse and read from any browser, at home or on your own server. Drop books into a folder, run the sync, and the shelf appears with covers extracted, titles searchable, and accents forgiven, so typing Bronte finds Brontë. Each reader in the house gets a profile that remembers their place in every book, and picking a book up on your phone resumes where the laptop left it, with a Continue button waiting on the shelf. EPUBs open chapter by chapter instead of downloading the whole archive, and PDFs stream in small ranged reads, so even a large scanned book opens quickly. Choose a two-page spread, a single page, or continuous scroll, then set paper, sepia, or night tints for longer sessions. E-readers join through the OPDS catalog, which lets a Kobo or Kindle-side client browse and download from the same shelf. There is no database to run and no account system to manage; the library is plain files you can back up with the volume.

Before a change lands in the main branch, Review Board gives your team a self-hosted code review server where reviewers read the diff, open issues on specific lines, and sign off with a Ship It. Post a review request from the web or with RBTools, either before you commit or after, and every update becomes a new revision that stays in the history. Interdiffs show exactly what changed between revisions, and moved-code detection keeps rearranged blocks from drowning out real edits. Comments can open issues that reviewers later mark fixed or dropped. Images and Markdown files can be reviewed alongside code, with split, onion-skin, color, and side-by-side diffs for pictures. A dashboard with customizable columns separates incoming from outgoing requests by review group. Connect Git, Mercurial, Subversion, or Perforce repositories, including ones hosted on GitHub or GitLab, and review them all on one server. Slack and Discord notifications, Jenkins builds, and Review Bot linters report back inside the review. Private repositories and hidden or invite-only review groups restrict who sees what, with sign-in through Active Directory, LDAP, or SAML 2.0. A REST API, WebHooks, and Python extensions cover custom workflows. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

With nearly 600 GitHub stars and a feature set that rivals commercial note apps, Glass Keep is the self-hosted Google Keep alternative that wraps a full-featured notes system in a glassmorphism UI with blurred backdrops, translucent modals, and smooth transitions. The React and Vite frontend renders notes in a masonry card grid with pinning, color themes, tag chips, and drag-and-drop reordering. Text notes support Markdown with headings, bold, italic, strikethrough, blockquotes, and fenced code blocks, while checklists offer inline editing, drag-to-reorder items, and direct toggle from the grid without opening the note. A freehand drawing mode provides customizable brush sizes and colors for handwritten notes. The private AI assistant runs an optimized Llama 3.2 (1B) model entirely inside the Docker container using RAG over your own notes, answering queries like "what are my AWS commands?" without any data leaving your server. Deep search spans titles, Markdown text, tags, checklist items, and image names. Import notes from Google Keep via Takeout JSON files or export your entire vault as JSON with per-note Markdown downloads. The Express backend with better-sqlite3 requires no external database. Real-time collaboration enables shared checklists with live item toggling. Dark and light themes persist across sessions, and the PWA manifest supports installation on any device.

Airstation turns your music folder into a radio station where every listener hears the same second of the same song at the same time. From the studio panel you upload tracks once, and they stay in a permanent library you can search and sort by date added, name, or duration. Build the broadcast queue by dragging tracks into order, reshuffle it whenever the mood changes, let it cycle endlessly, shuffle it randomly, or pause the station entirely when the day is done. Playlists group tracks for recurring shows, and the playback history shows listeners what has already aired. Anyone with the link opens the player page and is listening within seconds, no account and no app install, while a live counter tells you how many people are tuned in right now. The player page itself can be retitled to match your station's name. Friends get a shared listening moment instead of another playlist link, communities get a station that plays their own rotation around the clock, and collectors get to hear their library the way radio always felt: live, shared, and slightly out of your control once it starts.

HotHost answers the only two questions that matter about every server you own, is it up and is the disk about to fill, before your users ask them instead. One web container collects metrics from a tiny agent you paste onto each host as a Docker or shell snippet, and the fleet lands in a single table: hostname, public IP, RAM and disk usage, CPU model and cores, swap state, and country. Disk and RAM get loud ALERT badges at a configurable threshold, ninety percent by default, and notifications fire on failure and again on recovery, so a resolved incident closes its own loop. The same console watches your websites directly, requesting each URL on your interval and checking the status code, a required keyword in the response, or basic auth behavior. SSL certificates get an expiration reminder fourteen days out by default, long before the browser warnings start. When memory climbs, the top ten RAM-consuming processes are charted over the last two days, turning "something is eating the box" into a named culprit. Alerts route through Email, Slack, Telegram, or Gmail plugins, and the plugin system accepts your own notifiers.

SoftJL turns a system description into the UML diagrams, test cases, and Word specifications a software project is supposed to produce, and keeps every artifact traceable back to the requirement it came from. Describe your system in chat and confirm the extracted requirement rules, then work through feasibility analysis with system context, business and system flows, and implementation options weighed by cost, benefit, and risk. From the confirmed rules it builds requirement and design models: functional structure, use cases, domain concepts, architecture, design classes, database and deployment diagrams, all editable as PlantUML with SVG export. Tests follow the same thread, with normal, exceptional, and boundary cases mapped to requirement rules in coverage and traceability matrices that show exactly which requirements lack design or test support before you submit. When a requirement changes, dependencies and update status point at the models, tests, and documents that need review, instead of leaving you to rediscover them by hand. Specifications generate from the saved models as versioned, editable DOCX files, a feasibility report, a requirements specification, and a design description, ready to compare against the diagrams and revise. An optional read-only MCP endpoint lets a coding agent read your designs and acceptance criteria, and the whole workspace runs on your own OpenAI-compatible model service.

Operational watches your product for the moments that matter, signups, payments, failed webhooks and cron jobs, and pushes the important ones to your phone as they happen. Your code sends structured events with a name and a JSON payload through a simple API, using the official Node.js or PHP SDKs or the WordPress plugin, and every event lands in a searchable feed organized by project and category. Mark an event notify and it becomes a push notification on your phone through the installable web app, while everything else waits quietly in the feed for when you actually want to look. Related events nest inside each other as contexts, so a failed checkout can carry its payment attempt, gateway response and retry history in one expandable bundle instead of forty scattered log lines. Events can carry action buttons that trigger your webhooks, letting you approve a refund, restart a job or retry a delivery from the notification itself. Teammates share projects with their own accounts, a test mode lets you rehearse integrations without polluting the real feed, and a built-in MCP server exposes your events to AI tools.

Enterprise documentation discipline without enterprise infrastructure: Documize Community is the Confluence alternative built on exactly that trade. The entire platform - Go backend, Ember.js frontend - compiles to a single executable binary for Linux, Windows, and macOS with zero runtime dependencies: no Elasticsearch, no Redis, no JVM. Point it at PostgreSQL, MySQL, MariaDB, Percona, or Microsoft SQL Server (rare in open source, decisive in Microsoft shops), and schema migrations run on launch with native full-text search on whichever engine you chose. Content organization rejects nested-folder sprawl for Spaces, categories, and labels, and the section-based composable editor mixes rich text, Markdown, code blocks, PDFs, diagrams, and embedded Jira or Trello content in one document, with reusable blocks and templates so teams start from standards rather than blank pages. It deliberately unifies internal team docs and customer-facing documentation in one system with granular space-, document-, and action-level permissions deciding who sees what. Where wikis stop, Documize continues: content approval workflows (draft, review, approve, publish), version management, lifecycle control, feedback capture, PDF export, analytics showing what gets read and ignored, activity streams, and audit logs. Keycloak, LDAP, and SSO integrate for enterprise auth. AGPL-licensed.

Tugtainer delivers a visual command center for Docker environments that automates container image updates, monitors registry releases, and manages application lifecycles across multiple servers without command-line intervention. System administrators can inspect running containers across all connected hosts, trigger immediate image pulls, and configure automated cron schedules for recurring health and registry checks. Flexible update policies allow teams to flag production databases as notification-only while automatically updating stateless web applications whenever new image tags publish. When updating linked services, the platform analyzes Docker Compose project definitions and custom dependency labels to stop and restart containers in strict dependency order, preventing broken network links and orphaned volume mounts. Administrators can authenticate private container registries, browse image layers and tags, and view real-time container log streams directly within the browser console. Automated pruning jobs continuously reclaim server disk space by deleting obsolete, untagged images and dangling build layers after successful deployments. Multi-channel alerting integrates with over fifty notification providers, delivering real-time update summaries and error warnings directly to Discord, Telegram, Slack, and email webhooks.

PdfDing turns a scattered folder of PDFs into a proper library you can read, annotate, sign, and share from any browser. The viewer remembers exactly where you stopped in every document, so a manual opened on your desktop resumes mid-page on your phone, and progress bars in the library show how far you have read at a glance. Workspaces and collections group related documents, multi-level tags classify them, and starring, archiving, and bulk actions keep even a large archive tidy. Inside the viewer you can add text, highlights, and freehand drawings, then review and export your highlights and comments from dedicated sections and attach Markdown notes to a document. A signature you create once is stored on your server and waits for you on every device, ready to drop onto contracts and forms. Sharing a collection or a single PDF takes a link or a QR code, with optional access control over who can open it and for how long. Accounts are protected by OIDC single sign-on and two-factor authentication with TOTP or WebAuthn, and dark mode, an inverted color mode, and multiple layouts keep long reading sessions comfortable.

A personal flight logbook you host yourself, Jetlog draws every route you have flown on a pannable world map and turns the totals into charts. The home page opens with counts of flights, airports, hours, distance, and countries above that map, where dots mark visited airports and lines trace each trajectory. Settings let markers and lines grow with visit frequency and shade the countries where you have landed. Logging a flight takes only two airports and a date. Type a flight number and press Fetch to pre-fill the origin, destination, and airline, and a utility links connection flights automatically. Duration and distance are calculated for you and stay editable, with an option to use airport time zones. The All Flights table lists route, times, duration, distance, seat, class, and airline with filters and configurable columns, and each flight opens a detail page with airport data, a route map, tail number, and aircraft. A Statistics page charts flights per month, cumulative distance, most visited airports, most common airlines, ticket class, and seat for any time frame. History arrives through MyFlightRadar24 or custom CSV imports and leaves as CSV or iCal. Family members can share one install with separate logbooks, an admin manages the accounts, and the responsive layout works on a phone at the gate.

HabitSync treats habit tracking as a team sport, because willpower alone rarely survives February. Set each habit up the way life actually works: daily, weekly, monthly, on chosen weekdays, or at a custom interval, with a target value to reach or a ceiling to stay under for the habits you are trying to quit. Logging takes one tap, or a long press when today's effort deserves a custom number or a stopwatch. Share a habit with a partner, a sibling, or the whole household and everyone's progress sits side by side, which turns "did you go to the gym" into a question the dashboard answers. Monthly challenges raise the stakes with community voting, leaderboards, and medals for the top performers, while gentle automation watches your back: scheduled reminders when a habit goes unlogged, an alert when your completion slips under a threshold, and a quiet nudge when a friend overtakes you. Years of Loop Habit Tracker history import instead of being abandoned, and the installable web app keeps the streak one tap away on any device.

Larasend gives Laravel teams a self-hosted transactional email platform that sends through their own Amazon SES or Cloudflare account while keeping the dashboard, delivery logs, and message data on their own servers. Send mail with a simple POST to the emails API, or point existing mailables and notifications at the Larasend transport with one environment variable and no code rewrite. Every message lands in an activity dashboard where you can filter by status, search recipients and message IDs, open a preview with headers and metrics, and resend failures in one click. Delivery, bounce, complaint, open, and click events stream back from the provider and update each message timeline, so a missing receipt becomes a traceable record instead of a support mystery. Suppression lists build themselves from bounces and complaints, and guardrails watch complaint rates and verified domains before reputation damage can spread. Scoped API keys with expiration and rotation keep each project separate, while workspace roles control who can view, send, and administer. When replies arrive, the shared inbox threads inbound and outbound mail into conversations your team can assign, snooze, annotate, and answer with attachments and drafts. Webhooks notify your other systems about deliveries and inbound mail, and reusable templates keep recurring notices consistent across projects.

Mapping every physical server, virtual machine, container, and network link across a sprawling homelab into a live interactive canvas, Circuit Breaker gives infrastructure operators real-time topology visualization, IP address management, and rack elevation modeling on a single screen. Operators can switch between hierarchical, concentric, cortex ring, radial, and force-directed graph layouts where animated edges reflect link speeds and color-coded status rings display live hardware health. Automated discovery scans local subnets using nmap, SNMP, and ARP while querying Proxmox VE clusters, TrueNAS storage pools, and UniFi controllers, staging newly detected nodes in a review queue before adding them to the map. For multi-site labs or isolated VLANs, lightweight remote agents connect outbound over Noise-encrypted links after fingerprint approval to report host telemetry and run scoped network scans without opening inbound firewall ports. Rack diagrams let administrators drag servers into U slots with cabling overlays using a built-in catalog covering Dell, HPE, Supermicro, Ubiquiti, MikroTik, Synology, and APC gear alongside live iDRAC, iLO, and UPS metrics. Role-based access control, OIDC single sign-on, TOTP multi-factor authentication, encrypted full-state snapshots, and a SHA-256 hash-chained audit log keep multi-user operations accountable.

Cupdate keeps a watchful eye on every container image you run, reporting which ones are outdated or vulnerable while deliberately never touching the update button itself. Point it at a Kubernetes cluster, a Docker socket, or Podman hosts (local or remote, one or several) and it inventories every image in use with no configuration to write. Each image is matched against its registry to find the newest available version, and the dashboard shows the gap between what you deployed and what you could be running, with release notes inline so the decision to upgrade takes seconds instead of a changelog hunt. Vulnerability data is layered on top from four sources: Docker Scout for Docker Hub images, Clair for participating Quay images, GitHub Advisories for images tied to repositories, and osv.dev correlation for images shipping SBOMs. A dependency graph explains why each image exists in your stack by showing which workloads pull it, which ends the "can I delete this?" guessing game. Subscribe to the RSS feed to hear about new releases passively, query the REST API to drive scripts that update compose files or kustomizations, or surface outdated and vulnerable counts in a Homepage dashboard widget. Prometheus metrics and traces are available when you want the watcher itself watched.

Docker Updater puts you back in charge of container updates: it watches your registries for newer images, and nothing updates until you approve it, so no database restarts itself at dinner. Polls run on a schedule you set, and each container card shows the newer image waiting before anything is pulled. The check costs nothing: it compares the digest your container runs against the registry manifest without pulling a byte, across Docker Hub, GHCR and other Bearer-token registries. Read the last five GitHub releases for an image before committing, update one container or a batch, and watch the pull percentage, layer count and recreation step stream live on the card. If the new container fails to start, the old one returns automatically, and you can keep a backup even after a clean update. Not ready? Defer an update for 7, 14, 30 or 90 days, or indefinitely, and it leaves your notifications alone until then. Several Docker hosts join the same dashboard over SSH or TCP with health indicators, and Compose stacks restart together so services find new addresses. Notifications arrive through an auto-generated ntfy topic or your own Apprise URL, every update keeps a persistent log, and a reclaimable-images view shows what disk space old images hold. The dashboard serves on port 9090 in English or Simplified Chinese, with optional login.

One clean interface in front of Anthropic, OpenAI, Google Gemini, Cohere, and more: Chat Chat is a Next.js front door to the major AI providers, ending the juggling of separate subscriptions, tabs, and UIs per model. Bring your own API keys, pick a provider and model per conversation, and switch between them as the task demands: Claude for long-form reasoning, GPT for code, Gemini for multimodal work - the interface stays identical. Beyond configured presets, custom providers plug in with their own API endpoints and keys, which covers OpenAI-compatible gateways and local inference servers. The design splits into two dedicated modes: a chat interface for conversational work with customizable system prompts, and a search interface that pairs AI processing with query handling for research-style questions. The stack is modern and hackable - Next.js 14, Tailwind CSS, shadcn/ui on Radix primitives, Jotai for state - with full internationalization including English, Chinese, and Japanese. Self-hosting means your conversation history and API keys live on your instance rather than a third-party wrapper service, and pay-per-token API pricing typically beats stacking multiple monthly chat subscriptions. AGPL-licensed and deliberately simple to deploy: one container, environment variables for keys, done.

Comments for small sites without Disqus's baggage: Cusdis is a lightweight, privacy-first, open-source comment system for embedding under blog posts and articles. The embedded JavaScript SDK is about 5 KB gzipped (Disqus is roughly 24 KB), sets no cookies, runs no tracking, and does not require readers to create an account or sign in before commenting. Integration is two lines: a container div with your app ID and an async script tag, with ready-made adapters for common frameworks and static site generators. Moderation is approval-based - new comments stay hidden until you approve them from the dashboard, and email notifications include a Quick Approve link that approves or replies to a comment from your phone without logging in. A webhook fires on every new comment for integrations like Telegram notifications. The widget ships with built-in i18n and dark mode. The stack is TypeScript and Next.js with a Prisma data layer, deployable via Docker with PostgreSQL. Deliberately minimalist: no ads, no reader profiling, and your comment data lives in your own database.
