Before lifting a heavy four-unit storage server or rewiring a cramped network closet, you can map every unit of cabinet space in Rackula, an interactive drag-and-drop rack layout designer and capacity planner. Instead of staring at generic grey rectangles in a spreadsheet, you pull switches, routers, patch panels, UPS battery banks, and rackmount chassis from a hardware catalog populated with authentic front and rear faceplates from the NetBox device library. Equipment snaps cleanly to standard EIA-310 rack unit boundaries, while half-width gear and mini PCs nest inside one-unit carrier shelves and mounting brackets. Audiovisual technicians can group bayed cabinets side by side to plan amplifier racks, signal processor chains, and patch bays across multi-rack installations. Network engineers and data center operators can rearrange hardware with full undo and redo history, attach custom device graphics, and export crisp diagrams as PNG, SVG, or PDF files for runbooks and change control tickets. Sharing a proposed cabinet topology with a colleague in the field takes seconds using an encoded URL or a scannable QR code that opens on mobile browsers. Server-side persistence stores your rack definitions as portable YAML files and supports optional local accounts or OpenID Connect single sign-on for shared infrastructure teams.

A private ChatGPT built with Next.js: Lobe Chat is the open-source AI chat interface teams self-host instead. Its main advantage is provider breadth: one interface connects to 40+ model providers, including OpenAI, Anthropic Claude, Google Gemini, Mistral, Groq, AWS Bedrock, Azure, and local models served through Ollama, so you can switch models per conversation and compare outputs. It handles multi-modal work: image recognition, image generation, text-to-speech, and speech-to-text. A plugin system based on function calling and the Model Context Protocol (MCP) adds external tools like web search and code execution. Run it in standalone mode as a single container with settings in browser storage, or in database mode with PostgreSQL and S3-compatible storage for persistent history, multi-user auth, and RAG knowledge bases built from uploaded documents with pgvector retrieval. Because tools arrive through function calling and MCP rather than a proprietary plugin format, custom internal tools can be exposed to the assistant with a standard server over STDIO or HTTP. Hundreds of pre-configured assistant roles import from the community marketplace. For teams the cost model matters: provider API keys billed per token typically undercut a ChatGPT Plus seat per person, and self-hosting keeps API keys, uploaded files, embeddings, and conversation history entirely on your own server.

Social Analyzer scans over 1,000 social media platforms in parallel to discover and correlate user profiles from a single username query, making it the most comprehensive OSINT reconnaissance tool of its kind. Three detection modes cover different accuracy and speed tradeoffs: fast HTTP library checks for rapid sweeps, Selenium WebDriver validation for JavaScript-heavy sites, and a special mode for stubborn edge cases. String analysis generates username permutations and combinations to catch related accounts with slight naming variations. Three interfaces serve different workflows: a Node.js web application on port 9005 with a browser-based GUI, a CLI for scripted batch operations, and Python plus Node.js APIs for embedding into automated investigation pipelines. The QeeqBox OSINT library extracts profile metadata, screenshots, titles, descriptions, and activity patterns, all visualized through Ixora-based force-directed graphs that map relationships between discovered accounts. Tesseract OCR analyzes profile images for additional detection vectors. Search results narrow by country codes, website categories, Alexa ranking thresholds, and confidence levels. Optional Google API and DuckDuckGo API integration adds search engine correlation alongside direct platform queries. Docker deployment bundles Node.js, Firefox ESR, Tesseract, and all dependencies into one container. Trusted by law enforcement and security researchers for digital forensics and identity verification. 23,000+ GitHub stars. AGPL-3.0 licensed.

To listen to your favorite YouTube channels, video playlists, and Bilibili creators during a commute without keeping a browser tab open, PigeonPod converts video subscriptions into private, standard podcast RSS feeds for any podcast player. Paste a channel URL, playlist link, or single video address to preview uploads and generate a protected feed for Apple Podcasts, Overcast, Pocket Casts, or AntennaPod. You can select audio-only or video output, customize bitrates and formats, and generate Podcasting 2.0 chapter markers for topic scrubbing. Scheduled background sync jobs fetch new releases automatically while on-demand history backfill queues older catalog episodes in bulk. Per-feed keyword rules, duration thresholds, and retention limits keep storage clean by filtering out shorts or marathon livestreams. Upload YouTube or Bilibili cookies for member-only streams, route traffic through custom proxies, and update the yt-dlp engine directly inside the web dashboard. A built-in web player, one-click public episode share pages, and OPML export let you stream in the browser or migrate subscriptions. Media files store on local disk or S3-compatible buckets such as Cloudflare R2 and MinIO, accompanied by YouTube API quota monitors and failure alerts. Multi-user role permissions support shared accounts across eight interface languages.

Used by the Rust language community, NASA, Dropbox, and thousands of organizations worldwide with over 25,600 GitHub stars and 1,500+ contributors, Zulip is the only modern team chat app designed from the ground up for both real-time and asynchronous communication through its unique topic-based threading model where every message belongs to a named topic within a channel. This eliminates the context collapse of linear chat by letting teams follow specific conversations without scrolling through unrelated messages, resume threads days later without losing context, and catch up on missed discussions at per-topic granularity. Server 12.0 introduced end-to-end encryption for mobile push notifications, AI-powered search ranking, channel folders for workspace organization, and expanded video conferencing with Jitsi, BigBlueButton, and Zoom integration. Over 100 native integrations connect GitHub, GitLab, Jira, Sentry, PagerDuty, Travis CI, Redmine, dbt, Nextcloud, and n8n with bidirectional notifications, while LLM-driven agents access web-public channels via a standard llms.txt interface. Full-text search covers unlimited message history across all plans, code blocks render with syntax highlighting for 250+ languages, and LaTeX math expressions display inline. The REST API with typed Python and JavaScript SDKs enables custom bots, webhook integrations, and programmatic administration. Import tools migrate entire workspaces from Slack, Microsoft Teams, Mattermost, and Rocket.Chat.

KiCAD Prism gives hardware teams the review and release layer that KiCad and Git leave out, hosted on your own hardware with no proprietary ECAD cloud. Import projects from SSH or HTTPS Git remotes, monorepos included, and every revision opens in the browser across schematic, PCB, 3D, BOM, and stackup views. Cross-probing links the views together, insets open a live view of the other document from any pin or pad, and selecting a net highlights it across schematic, PCB, and 3D with its routed length, layers, tracks, and vias. Reviewers comment on any sheet, part, or area with rich text, pasted snips, and attachments anchored to the exact revision, optionally publishing the discussion to GitHub or GitLab issues. Design Comparison lines two revisions up and lists what changed across schematic, PCB, BOM, stackup, and fabrication outputs, highlighted on the sheet beside the review thread. Release Studio then walks a committed revision through source, identity, manufacturing, build, outputs, and publish, building fabrication and assembly files, showing Gerbers in the browser, recording DRC and ERC evidence and designer and QA sign-off, and publishing the approved package to GitHub or GitLab Releases. Library Manager governs components as a catalog of immutable revisions with symbol, footprint, 3D, and SPICE assets and a QA release flow, delivered into desktop KiCad through the Remote Symbol Provider.

Hand a task to an AI teammate the way you would hand it to a person: describe the work, then follow along and step in when it matters. UseAgent runs Claude Code, Codex, OpenCode, and Pi inside isolated Linux workspaces, each with your repositories, a terminal, a real browser, and a desktop you can open and take over. Start work from the web app, by mentioning an agent in Slack, or through the API, and get pull requests, documents, spreadsheets, presentations, and research back as usable files. Four engines share one thread and one event format, so you can compare how Claude Code and Codex each handled the same bug, then switch engines on the next reply without losing history, files, or memory. Risky operations pause at approval gates, and a decision resumes the run with a one-shot, argument-bound capability instead of blanket trust. Every step, tool call, and approval is stored as an append-only event log in your Postgres, replayable after the fact and durable across restarts mid-task. Teach the workspace your procedures by importing versioned skills from GitHub and pinning playbooks to tasks, while knowledge pages and optional team memory stay beside the work, inspectable and correctable. Recurring tasks run on schedules with full history. Provider keys stay on your server and never enter an agent sandbox.

FerretDB gives you the MongoDB developer experience without the SSPL: point your existing drivers at it and your document workloads land in PostgreSQL instead. It listens on the standard MongoDB port and translates wire-protocol queries into SQL, so applications, ORMs, and command-line tools connect unchanged, none the wiser. CRUD operations, aggregation pipelines, index creation, findAndModify, and sessions all work today, with new commands landing release after release as compatibility widens. Behind the proxy, Microsoft's open-source DocumentDB extension gives PostgreSQL a native BSON type and document operators, which is also the engine under Azure Cosmos DB for MongoDB vCore. That shared engine means workloads can move between your own FerretDB deployment and Cosmos DB without an export-import project in between. Vector search support covers embedding lookups for AI features, replication covers high availability, and SCRAM-SHA-256 authentication secures connections the way MongoDB operators already expect. Because the license is Apache 2.0, you can embed it, resell it, or offer it as a managed service to your own customers with no SSPL obligations attached.

Self-hosting a language model is only half the job; people still need somewhere pleasant to talk to it, and Chat UI is that window, the same interface that powers HuggingChat. Point it at any OpenAI-compatible endpoint, your own Ollama or llama.cpp server, the Hugging Face router, or a hosted gateway like OpenRouter, and the models it serves appear in the picker automatically, with no per-model configuration. Conversations are saved to your database and stay browsable in the sidebar, so a thread from last week can be reopened, continued, and compared against a fresh answer from another model. Multimodal models accept image uploads right in the composer, and models that support it can call MCP tools mid-conversation to fetch data or run actions. For a shared team deployment, OpenID Connect sign-in keeps individual histories and settings separate, and per-user defaults travel with each account. Everything a consumer chatbot would keep on someone else's servers, prompts, uploaded files, and usage history, stays in the MongoDB you control on the same machine. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Excaliself turns the Excalidraw canvas into your team's own whiteboard server, where every sketch, diagram, and flowchart lives in your database instead of a vendor's cloud. The home screen works like a file cabinet for drawings: nest them in folders, star the keepers, drag files between spaces, and find anything again by title or by the text inside the drawing. Share a link and teammates edit together in real time with live cursors and follow mode; links can stay members-only or open to guests who have no account at all. A shared Team space sits next to everyone's private space, and one team library holds the shapes and icons the whole group reuses. AI clients can join with a personal access token: Claude Code or Claude Desktop can search your drawings, read what a diagram says, and create new ones from shapes or a Mermaid flowchart. Accounts are invite-only, single sign-on covers Google, Microsoft, and any OIDC provider, and admins manage members, roles, and password resets from Settings. Deleted drawings rest in a trash folder for thirty days before they are purged, and everything auto-saves as you draw.

One self-hosted workspace holds your team's chat, tasks, notes, and calendar, and Deft lets AI agents work in it beside your people. People get real-time chat with spaces, direct messages, threads, mentions, reactions, files, and presence. Tasks open as Board, Table, Timeline, or Calendar views, with dependencies, subtasks, recurrence, and bulk actions. Notes, decisions, and channel memory become durable knowledge, with graph views and links back to the source conversation. Native calendar events sit beside read-only ICS subscriptions. Agent employees can join channels and receive task assignments. Tag the built-in assistant Defty to draft a task, answer a workspace question, or take a governed action, then review the proposal in an approval card before anything changes. Personal connections let Codex, Claude, ChatGPT, and other streamable HTTP MCP clients act as the signed-in user within revocable scopes. Approval tiers, trust levels, token scopes, revocation, activity history, and action receipts record who or what acted and what changed. OpenAI, Anthropic, OpenRouter, OpenAI-compatible endpoints, and local Ollama-style models are supported providers. Chat, tasks, notes, and calendars keep working with no AI key. Modules add company-specific records, relationships, and views, with a bundled Contacts module as the first example. 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-only licensed.

Links rot - the hard truth Linkwarden is built around, as a collaborative bookmark manager that preserves what it saves. Every page you save is fully preserved - a screenshot, a PDF, a self-contained single-file HTML archive (generated by the Monolith Rust binary), and a clean reader view - so the content survives even after the original site disappears. Think of it as a private Wayback Machine you own, with an optional one-click snapshot to archive.org on top. The reading experience matches the archival rigor: a distraction- free reader view supports text highlighting and annotation, and full-text search across everything you have saved is powered by Meilisearch. Optional AI tagging analyzes page content and auto-assigns tags - generate new ones, pick from your existing set, or constrain to predefined tags - with providers ranging from local Ollama models (fully private) to OpenAI, Anthropic, and OpenRouter. Organization is collections, sub-collections, and multiple tags per link; teams collaborate on shared collections with per-member permissions, and public collections share curated link sets (with preserved copies) to anyone. The stack is Next.js/React on TypeScript with PostgreSQL via Prisma, NextAuth supporting credentials, OAuth2, and SAML SSO, and a Playwright-driven headless Chromium worker doing the capture. Native iOS and Android apps and browser extensions feed it from anywhere.

Define a DocType in Frappe and the framework automatically generates database tables, Python ORM classes, REST API endpoints, form views, list views, and role-based permission rules from that single schema definition. The meta-driven architecture stores schemas as database records, letting administrators add fields, reorder layouts, and modify validation rules through the browser-based Form Builder without redeployment. Server-side Python controllers handle business logic through hook-based lifecycle events while client-side JavaScript manages interactive form behavior, with WebSocket connections providing real-time updates across sessions. The built-in workflow engine defines document state machines with role-gated transitions, email notifications, and conditional action visibility. Pre-configured Desk views include list, form, report, tree, kanban, calendar, and dashboard layouts with drag-and-drop workspace customization. The report builder generates grid reports with configurable columns, filters, grouping, and chart visualizations from DocType data or custom SQL and Python scripts. Background job processing uses Redis queues for email delivery, data imports, and periodic tasks. Virtual DocTypes connect external databases to the framework's UI without data migration. Docker deployment via frappe_docker provides production-ready Compose configurations with MariaDB, Redis, Nginx, and worker containers. The foundation powering ERPNext, HRMS, CRM, and Helpdesk in production. Over 10,500 GitHub stars. MIT licensed.

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.

With over 77,000 GitHub stars, Crawl4AI is the most-starred open-source web crawler on GitHub and the go-to tool for converting the web into AI-ready data. Built on Python and Playwright, it transforms any website into clean Markdown with headings, tables, code blocks, and citation hints optimized for LLM ingestion, or extracts structured JSON via CSS selectors, XPath expressions, or direct LLM-based schema extraction through OpenAI, Anthropic, and Ollama providers. The self-hosted Docker server exposes a REST API on port 11235 with endpoints for crawling, streaming results, screenshots, PDF generation, JavaScript execution, and LLM-powered extraction. Version 0.9.x introduced secure-by-default operation with mandatory JWT authentication, strict request validation, declarative hooks replacing inline code, and bounded job queues. Adaptive crawling uses information foraging algorithms to determine when sufficient data has been gathered, while deep crawl mode traverses link graphs intelligently. The async browser pool manages concurrent sessions with stealth plugins, proxy rotation, custom headers, and session persistence for authenticated scraping. A built-in MCP server enables direct integration with Claude, ChatGPT, and Cursor for AI-driven web research workflows. Content filtering applies BM25 and TF-IDF relevance scoring to extract only pertinent sections from noisy pages.

Authentication that lives inside your application rather than behind a redirect to an external identity provider - SuperTokens takes a fundamentally different architecture from Auth0 and AWS Cognito. Three tiers make that work - frontend SDKs (React, Angular, Vue, vanilla JS, React Native) render overridable login UI and manage tokens; backend SDKs (Node.js, Python, Go) expose auth endpoints on your own API domain; and SuperTokens Core, the piece you host here, is the stateless HTTP service handling core auth logic, password hashing, token signing, and database operations against PostgreSQL. The recipe system keeps features decoupled: use email/password, social login, passwordless (magic links, OTP), phone-password, multi-factor authentication (TOTP, WebAuthn), user roles, and microservice auth - individually or combined; you can even use SuperTokens purely for session management alongside another login provider. Sessions are where it shines: rotating refresh tokens with theft detection, automatic access-token refresh, CSRF protection, and secure cookie handling out of the box - the details that become vulnerabilities when hand-rolled. Verification happens locally in your backend via cached JWT signing keys, so the Core stays off the hot path. Self-hosted means no user limits, free forever, with all user data in your database.
