A free, polished web client for Subsonic-compatible music servers: Substreamer is the browser-based frontend you point at your existing streaming backend to play your own library from anywhere. It speaks the Subsonic API (v1.13 and higher), which makes it compatible with the whole ecosystem that has grown around that protocol: the original Subsonic server, its forks Airsonic and Madsonic, and modern implementations like Navidrome and Ampache. That decoupling is the point - your music files, transcoding, and library indexing live on whichever server you prefer, while Substreamer provides the listening experience: browse by artist, album, and genre, build and manage playlists, search your collection, and stream on demand. This RepoCloud deployment runs the containerized web edition, so the same interface is available from any browser without installing a native app, and it pairs with the Substreamer mobile apps that made the client popular. For anyone assembling a self-hosted Spotify replacement - typically Navidrome for the backend plus a good client - Substreamer fills the client half with a clean, familiar player UI. Because it is a stateless client, the container is lightweight and low-maintenance: connect it to your server's URL and credentials, and your entire collection is streaming in minutes, with no subscription and no catalog that can disappear.

IRONSIGHT fuses over 50 publicly available intelligence sources into a single real-time dashboard that requires zero API keys and zero configuration. The Live Intel Feed aggregates 20+ RSS news sources with keyword relevance filtering from outlets including Reuters, Al Jazeera, and Kyiv Post. The Telegram OSINT module scrapes 27 channels every 60 seconds with automatic translation from Hebrew, Arabic, and Farsi. The interactive Leaflet Theater Map plots military aircraft positions via ADS-B transponder data, naval vessel locations in the Persian Gulf and Eastern Mediterranean, strike markers extracted from news and Telegram, missile trajectory arcs with range rings, and country-border overlays with a distance measurement tool. A header toggle switches the entire dashboard between Iran/Israel and Russia/Ukraine theaters, re-pointing every panel, map layer, and data feed to the selected conflict. The Israel Alert module streams live Pikud HaOref missile alerts with audio notifications, while the Conflict Monitor categorizes events into strikes, defense, diplomatic, and nuclear. Financial panels track defense contractor stocks, S&P 500, VIX, gold, Bitcoin, Ethereum, energy commodities via Yahoo Finance, and Polymarket prediction odds on conflict outcomes. NASA FIRMS satellite thermal detection flags fire and explosion signatures. The Next.js 16 App Router handles server-side data fetching for RSS and API endpoints while client-side React state management drives real-time polling updates.

Continuous infrastructure monitoring meets automated SSL expiration tracking in Kuvasz, a self-hosted uptime platform that alerts DevOps teams before outages disrupt production operations. Operators can configure granular health checks across HTTP endpoints, ICMP ping targets, and raw TCP ports with custom polling intervals down to seconds. Automated SSL inspectors track certificate validity, issuing early warning notices before cryptographic chains expire and disrupt production traffic. A push monitoring system receives incoming heartbeat signals from background cron jobs, database backups, and recurring automation scripts, triggering alerts whenever expected pings fail to arrive on schedule. Multi-channel dispatchers route incident notifications through Slack, Discord, Telegram, Microsoft Teams, PagerDuty, and custom webhook payloads with adjustable failure count thresholds to eliminate transient false alarms. Maintenance windows let teams schedule planned downtime through one-off intervals or recurring cron expressions, automatically muting notifications during deployment cycles. Public and private status pages publish categorized system health metrics, historical latency charts, and incident timelines to keep internal stakeholders and end users informed. An integrated Model Context Protocol server allows AI assistants to query monitoring states and toggle checks directly via conversational interfaces.

Scattered browser tabs, buried wiki folders, and disconnected issue trackers fragment engineering context across too many tools, which is why Ideon unifies your repositories, notes, and tasks on a shared infinite canvas. Rather than forcing projects into rigid folder hierarchies, you arrange interactive blocks spatially on a two-dimensional map where related documents, checklists, calendar schedules, and code references sit right beside one another. Teams can embed live repository cards and open issue streams directly from GitHub, GitLab, Gitea, and Forgejo onto the workspace, keeping code status visible alongside architecture documentation. Rich content blocks render Markdown notes with threaded comments, Mermaid flowcharts, uploaded files, images, and bookmarked links on the same board. Real-time multiplayer collaboration lets teammates edit blocks simultaneously, follow live cursors across the canvas, and map system designs together without edit conflicts. Built-in Time Travel snapshots capture historical states of the workspace so you can scrub backward to review how a project evolved or trace past design decisions. You can even synchronize an entire project canvas directly to a Git repository, storing notes and spatial block layouts as versioned files.

If an assembly needs motions, amendments, speaker lists, and secret ballots on one shared screen, OpenSlides is the open-source web application that runs them. Before the meeting, administrators set up committees and meetings, import participants from CSV or connect a SAML identity provider for single sign-on, email invitations with login data, and sort people into groups with freely defined rights. Members file motions in an HTML editor, attach documents, gather supporters, and send them through customizable workflows with automatic numbering by category, and amendments and change recommendations attach to specific line numbers. Motions can be forwarded to other meetings. During the session the agenda reorders by drag and drop, and every item, motion, or election gets its own speaker list with countdowns, points of order, and recorded speaking time. Votes are open, secret, or nominal and run live for present participants in voting groups, with proxy delegation, vote weighting, multiple rounds, and Yes/No/Abstain options per candidate or list. Results appear against a chosen reference value on projectors, in PDF exports, or as individual tallies. Several projectors can show the current item, a lower third for the active speaker, and live results, and Autopilot guides participants through whatever is happening. A video livestream brings in remote attendees. Afterward, motions export to PDF, CSV, or XLSX.

Report cards, attendance rosters, class schedules, discipline logs, and fee statements all live in one browser-based system with RosarioSIS, an open-source student information system for K-12 schools and similar institutions. Administrators define marking periods in up to three tiers, set grade levels and daily periods, and search students by gender, grade level, schedule, absences, GPA, or class rank. The scheduler places whole classes or a single student, and runs in test mode each time a student's requests are saved, so conflicts can be resolved with the student still in front of you. Teachers keep a weighted gradebook with grade ranges, progress reports, report cards, and transcripts, take attendance electronically, and use the eligibility feature to flag who may join athletic or academic activities. Discipline logs, student billing with fees, payments, balances, and statements, food service, and accounting complete the core modules. Parents and students get their own portal, new families can register online, listings export to Excel, CSV, or XML, and charts and PDF documents support decisions and paperwork. The interface adapts to tablets and phones and is translated into a dozen languages. Add-on modules bring email, library, hostel, Jitsi Meet video rooms, and Moodle integration.

Sage Wiki turns a pile of unstructured documents into a fully interlinked, searchable wiki by running them through a five-pass LLM compiler pipeline. Inspired by Andrej Karpathy's vision of LLM-compiled knowledge bases, the pipeline processes source files through diff detection, summarization, concept extraction, image captioning, and cross-reference discovery, with parallel LLM calls and checkpoint/resume for vaults scaling to 100,000+ documents. The typed ontology graph stores entities and relations with BFS traversal, configurable relation types, multilingual synonyms, and a promotion/demotion lifecycle backed by grounding verification and consensus scoring. Multi-format ingestion handles Markdown, PDF, Word, Excel, PowerPoint, EPUB, email, CSV, images, and code files without manual tagging. LLM provider support spans Anthropic, OpenAI, Gemini, Ollama, and any OpenAI-compatible API, with per-pass model routing enabling cost optimization by assigning cheaper models to simpler tasks. The built-in MCP server exposes 17 tools over SSE transport for integration with Claude, Cursor, and any MCP-compatible agent, while native Obsidian vault overlay ensures existing note workflows remain undisrupted. Team deployment supports Git-synced shared wikis, centralized server access, and hub federation across multiple projects. Ships as a single Go binary with Docker Compose multi-arch images serving the web UI on port 3333.

Watching a MikroTik RouterOS v7 router in real time is what MikroDash is for: live traffic, connections, Wi-Fi clients, DHCP leases, and WireGuard peers reach the browser the moment anything changes. Cards drag into any layout, and the arrangement follows your account to every browser. Managing a fleet happens on the Devices page, which shows routers as cards, a list, or a world map with 24-hour connectivity, last backup, open alerts, and pending updates. Rolling out a change starts in Config Management: choose one of 20 ready-made templates or capture your own, then deploy to one router or the fleet with a restore point, a canary router, and an automatic revert if a change cuts MikroDash off. Scheduled backups are kept only when something changed, with a diff and a guarded restore. New sites join through a generated script that calls home over a built-in WireGuard tunnel, even from behind NAT. Alerts reach SMTP, Telegram, ntfy, Discord, Slack, Gotify, Pushover, and Apprise. Troubleshooting stays in the browser with ping, traceroute, torch, bandwidth tests, a packet sniffer, and a RouterOS terminal. Read-only API access covers every page and alert, while roles, OpenID Connect sign-in, and an audit trail of every write govern shared use. Off by default, an optional assistant answers from live router data and asks before changing anything.

Cataloging tables, topics, queues, and APIs across fragmented data stacks usually demands heavyweight enterprise governance suites, yet Marmot delivers fast full-text asset discovery and AI-ready metadata context in a single self-hosted service. Data engineering and platform teams use its 71 official plugins to automatically ingest schemas, run histories, and dependencies from Apache Kafka, Airflow, Iceberg, Superset, PostgreSQL, BigQuery, and AsyncAPI specifications without moving raw table rows or message payloads. From the web interface, analysts can run structured boolean queries, filter assets by custom tags or PII classifications, and inspect column-level schemas in seconds. Interactive upstream and downstream lineage graphs let engineers trace how events flow from message brokers into warehouse tables and BI dashboards so they can assess what breaks before renaming a column or deprecating an endpoint. Shared business glossaries, bidirectional ownership assignments, and curated data product bundles ensure every department speaks the same language and knows exactly which team maintains each pipeline. Through the built-in Model Context Protocol server, AI assistants in Cursor, Claude Desktop, and LibreChat can invoke tools like discover_data, find_ownership, and lookup_term to answer natural-language questions against live catalog metadata instead of guessing. Platform administrators can also manage catalog resources declaratively using the REST API, CLI, Terraform provider, or Pulumi integration.

Wiki-Go turns a folder of Markdown files into a searchable team wiki with page history, comments, and access rules, and never asks you to run a database. Pages live in a nested tree with a sidebar and breadcrumbs, and an editor with a preview toggle handles emoji shortcodes, highlighted code, LaTeX math, Mermaid diagrams, collapsible sections, GitHub-style alerts, and embedded YouTube, Vimeo, or MP4 video. Full-text search supports exact phrases in quotes and term inclusion or exclusion, and highlights each match. Each save keeps a revision, up to a configurable limit, and any stored version can be restored later. Attachments such as PDFs, spreadsheets, images, and archives sit beside the page they belong to. Drop a Kanban board into any document for drag-and-drop task tracking with nested tasks, or build a categorized link library that fills in page metadata automatically. Signed-in users comment in Markdown, and admins can remove comments. Admin, editor, and viewer roles, user groups, path-based public or private rules, and an optional private-wiki mode decide who sees what. Branding comes from a custom logo, banner, and favicon, shortcodes such as stats insert live site statistics, and readers can switch between dark and light themes or print any page. A REST API opens content to scripts, and a community tool imports Notion exports. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.

Publish the answers your team keeps repeating as a multilingual, searchable FAQ with phpMyFAQ, a knowledge base whose admin area handles writing, review, and permissions. Organize entries in nested categories that you rearrange by drag and drop, attach files, add tags and related FAQs, and let visitors leave comments. A WYSIWYG editor with an image manager writes each answer, a wiki-style revision history restores earlier versions, and a news system posts announcements. Full-text search covers every language, and optional Elasticsearch or OpenSearch backends handle larger collections. The interface covers more than 40 languages with right-to-left layouts, automatic content negotiation, and translated categories and entries. Privileges work per user and per group, so an editor can change an entry without being allowed to delete it, and categories can be limited to chosen readers. Sign in through LDAP, Active Directory, or Microsoft Entra ID, protect accounts with two-factor authentication, or try experimental passkeys. The dashboard charts 30 days of visits, lists inactive FAQs, and checks installed files against published hashes. Export entries to PDF, publish a dynamic sitemap, back up your content, and filter spam with built-in protections. Dark, light, and high-contrast themes keep the public site comfortable to read. Scripts and AI assistants reach the knowledge base through a REST API with an OpenAPI specification or an experimental MCP server, and plugins extend it.

Instead of paging through albums, Photofield lays a whole photo library out on one zoomable canvas, where thousands of thumbnails sharpen into full-resolution pictures as you zoom. Collections come straight from directories named in a configuration file. One setting turns every subfolder into its own collection. Pick a layout per collection: album grouped by date, timeline with month markers, wall, map, highlights with dates and place names, or flex. Sort oldest first, newest first, or shuffled hourly, daily, weekly, or monthly. Tiles load progressively, and an info drawer shows the date, file name, and dimensions. A right-click menu opens or copies an image, copies its link, or finds similar images. Originals are never modified, so a read-only mount is safe. Indexing runs at up to 10,000 files per second on a fast SSD with a warm cache. JPEG, PNG, AVIF, HEIC, DNG, GIF, MP4, and MOV files are recognized. Place names resolve from an embedded database, with no external lookups. The optional photofield-ai companion adds search by words like beach sunset or cat eyes, plus a Faces layout of detected faces. Alpha tagging lets you label photos.
