Previously known as Hoarder and now holding 28,000+ GitHub stars, Karakeep is the most popular open-source bookmark-everything application — combining AI-powered automatic tagging with full-text search, page archival, and cross-platform access for digital content hoarders who refuse to let valuable links disappear. The Next.js frontend with tRPC communication delivers a responsive interface for saving links, notes, images, and PDFs, while Puppeteer crawls bookmarked pages to fetch titles, descriptions, and images automatically. LLM-based auto-tagging supports OpenAI, Anthropic, or local models via Ollama for privacy-first deployments that never send data to external services. Meilisearch powers full-text and semantic search across all stored content including OCR-extracted text from images. A rule-based automation engine triggers custom actions based on bookmark properties — automatically sorting, tagging, or archiving content matching defined conditions. Full page archival via Monolith preserves complete page snapshots against link rot, while yt-dlp integration archives videos from YouTube and other platforms. RSS feed ingestion automatically captures new articles from subscribed sources. Collaborative lists enable teams to build shared bookmark collections, with per-list permissions and real-time sync. Native iOS and Android apps, Chrome and Firefox extensions, and browser bookmark sync via Floccus ensure capture from any device. Importers migrate data from Chrome, Pocket, Linkwarden, Omnivore, and Tab Session Manager. 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.

Your Gmail, Google Workspace, or Outlook inbox, worked by an AI assistant: Inbox Zero sits on top of the account you already have. Its core idea is rules written in plain English - tell the assistant "label invoices and file the PDF to Drive" or "archive cold outreach unless they mention my company" - and it executes against every incoming message. Emails that need a response arrive with a pre-drafted reply written in your tone, learned from your email history and calendar context. Reply Zero tracks what you owe responses to and what you're waiting on; the Bulk Unsubscriber surfaces newsletters you never read (with read-rate analytics) for one-click unsubscribe-and-archive; the Cold Email Blocker auto-archives unsolicited pitches based on your own definition of "cold." Smart Filing routes attachments - receipts, contracts, PDFs - into the right Google Drive or OneDrive folder, and Slack/Telegram integration lets you read, draft, and triage without opening a mail client. Email analytics show top senders and volume trends. It is not a new email client: everything happens in your real mailbox using native filters. Self-hosting means your mail content and the LLM calls that process it run on infrastructure you control.

Hoarder (now Karakeep) is a bookmark manager that actually fights link rot: every page you save gets archived at capture time using Monolith, so the content survives even when the original URL dies. Beyond archival, an AI layer powered by OpenAI or local Ollama models auto-tags everything by analyzing page content. Prefer full privacy? Ollama keeps all inference on your server with zero external API calls. Full-text search through Meilisearch indexes the actual scraped content of every bookmark, not just titles and tags, so you find articles by what they say rather than labels you half-remember. Save links with automatic metadata extraction, plain text notes, uploaded images, and PDF documents, all organized into shareable lists with collaborative access. Browser extensions for Chrome and Firefox make saving a one-click operation from any page. Migrating is painless with importers for Chrome, Pocket, Linkwarden, Omnivore, and Tab Session Manager. LLM summarization condenses saved pages into brief overviews for quick scanning. The AI layer is entirely optional: Hoarder works perfectly as a manual bookmark manager, with intelligence adding convenience rather than imposing a requirement. SSO integration and responsive dark mode round out the package.

Every wiki page lives as a plain-text file in a standard Git repository, giving you full version history, branching, merging, and the freedom to edit with any text editor or IDE alongside the web interface. Originally built by GitHub's founders as the engine behind GitHub's own wiki feature, Gollum supports Markdown, AsciiDoc, reStructuredText, Org-mode, Textile, MediaWiki, Creole, and Pod markup formats with live preview rendering as you type. PlantUML and Mermaid diagrams render inline for architecture documentation, MathJax handles mathematical notation, and BibTeX integration via Pandoc provides academic citation management. YAML frontmatter controls per-page sidebars, headers, footers, and table of contents generation. CriticMarkup annotations enable editorial review workflows with tracked insertions, deletions, substitutions, and comments. Macros extend pages with dynamic content injection, file includes, and navigation helpers. The wiki maintains compatibility with GitHub and GitLab wiki repositories, so teams can clone existing platform wikis for local editing and offline access. The official Docker image at gollumwiki/gollum exposes port 4567 with volume-mounted repositories, requiring roughly 170 MB of container storage and minimal RAM. Authentication integrates via OmniAuth supporting GitHub, GitLab, Google, and other OAuth providers. Over 14,300 stars on GitHub since 2009. MIT licensed.

A recipe manager that feels like a consumer product rather than a homelab experiment: Mealie pairs a FastAPI backend with a reactive Vue frontend for the most polished self-hosted meal planning around. The killer feature is the recipe scraper: paste a URL from hundreds of supported cooking sites and Mealie imports the ingredients, steps, times, and photos automatically. Structured HTML/JSON paste, a Markdown-capable manual editor, and imports from other recipe apps (like Tandoor) cover everything else. Meal planning uses a drag-and-drop calendar with breakfast, lunch, dinner, and snack slots, plus rule-based random recipe insertion - constrain the pool by tags or categories per meal type or weekday. Shopping lists link recipes so all ingredients land in one place, organized into supermarket sections, and update in real time for everyone in the household. The multi-tenancy model is genuinely thought through: isolated Groups can host multiple tenants, and Households within a group share recipes and organizers while keeping meal plans and shopping lists private. Cookbooks group recipes by your own criteria, a cooking mode stays readable on a phone propped against the backsplash, and 35+ language translations ship built-in. A fully documented REST API and scheduled webhooks (e.g., today's meal plan to Home Assistant) make it automatable, with SQLite or PostgreSQL storage and automatic backups.

Mail-in-a-Box turns a single Ubuntu server into a fully functional email system with one setup command, installing and configuring Postfix for SMTP, Dovecot for IMAP, Roundcube for webmail, and Z-Push for Exchange ActiveSync push notifications in an automated sequence that would take days to replicate manually. The DNS server auto-configures the full suite of email authentication records: SPF, DKIM, DMARC, DNSSEC with DANE TLSA, MTA-STS, and SSHFP. Getting all of these right is what separates email that lands in inboxes from email that lands in spam, and most manual installations never achieve the complete set. Nextcloud integration adds CardDAV contact sync and CalDAV calendar sharing across devices. Let's Encrypt certificates provision and renew automatically for every hosted domain. The web control panel manages users, aliases, custom DNS records, and automated backups, protected by TOTP two-factor authentication. Daily health checks verify that services run correctly, ports remain open, TLS certificates stay valid, and DNS records resolve properly, alerting you before delivery problems develop. Multiple domains and users operate from one installation with internationalized domain name support. Built-in HTTPS static site hosting uses the TLS infrastructure already in place. Runs on a dedicated RepoCloud VPS with guaranteed resources, root SSH, and browser serial console for complete email sovereignty. CC0 public domain licensed.

Amplication turns entity definitions into production-ready backend services, generating NestJS with Prisma and Apollo GraphQL for Node.js or ASP.NET Core for .NET, eliminating months of boilerplate. The plugin-driven Data Service Generator hooks into code generation lifecycle events, enabling teams to inject CI/CD manifests, proprietary authentication schemes, testing configurations, and cloud-specific deployment targets for AWS, Azure, and GCP without forking the core generator. Blueprint templates encode organizational architecture standards, security policies, and coding conventions into reusable foundations that keep every generated service consistent across the engineering organization. Jovu AI translates natural language requests into entities, relationships, fields, modules, DTOs, and custom API actions, automatically aligning each resource with predefined standards. Generated services include full CRUD operations with input validation, Swagger/OpenAPI documentation, authentication middleware, database-agnostic ORM via Prisma, optional React Admin interfaces, and Jest test scaffolding. Code output syncs to Git repositories as pull requests, preserving standard review workflows while letting developers edit every generated line and add custom business logic. Supports PostgreSQL, MySQL, and MongoDB as database targets. Over 16,000 GitHub stars with enterprise adoption. Apache 2.0 licensed.

Built for self-hosting from the ground up, Kutt is a modern, MIT-licensed URL shortener: zero-configuration setup, no build step, and SQLite, PostgreSQL, or MySQL with optional Redis caching. Links carry real management features - custom slugs from a configurable alphabet (confusable characters like 0/O and l/1 omitted by default), password protection, descriptions, expiration times, and the ability to edit a destination URL without changing the short link already in circulation. Custom domains make branded short links first-class: add as many as you like and serve each under your own name instead of a third-party's. Private, per-link statistics track clicks, browsers, operating systems, and countries without logging visitor IPs or sensitive data. An admin page manages users and links instance-wide, and two environment flags (DISALLOW_REGISTRATION, DISALLOW_ANONYMOUS_LINKS) lock the instance down for private use; OpenID Connect login integrates with an existing identity provider. Automation runs through a documented REST API - create, list, delete, and pull stats - plus Chrome and Firefox extensions and ShareX compatibility for shortening from anywhere. Built with Node.js and React, deployed in one Docker container, it replaces Bitly with something you own: your domain, your analytics, and links that never die with a vendor.

Authelia is the leading open-source SSO and multi-factor authentication server for self-hosted infrastructure. The Go backend compiles to a single binary or Docker container image, serving a TypeScript React web portal that handles first-factor username and password login, second-factor authentication via TOTP, WebAuthn FIDO2 security keys, passwordless passkeys, and Duo mobile push notifications, and an OpenID Connect 1.0 and OAuth 2.0 identity provider with device code flow, JWE encrypted ID tokens, custom claims policies, and network-scoped authorization criteria. The forward authentication model integrates with Nginx auth_request, Traefik ForwardAuth, HAProxy, Caddy, Envoy, SWAG, and Skipper reverse proxies, injecting Remote-User, Remote-Groups, and Remote-Email headers into authorized requests. Granular access control rules match subject, groups, request URI, HTTP method, and network to enforce one-factor and two-factor policies per route. The user backend supports LDAP with attribute mapping, connection pooling, and bind mode, or YAML file-based authentication with Argon2id hashed passwords. Session state stores in Redis for high availability across clustered deployments, while persistent data lives in SQLite, MySQL and MariaDB, or PostgreSQL. Brute force protection locks accounts after configurable failed attempts, and email-based identity verification handles password resets and device registration. Dark, light, and OLED themes with i18n localization customize the portal appearance. On RepoCloud, deploy Authelia on a dedicated VPS with Docker, root SSH access, and complete control over your authentication infrastructure, all under the Apache-2.0 license.

Scira is an AI search engine that breaks complex research questions into sub-tasks, retrieves grounded answers from live sources, and cites every claim with clickable links to the original evidence. Formerly known as MiniPerplx and now backed by nearly 12,000 GitHub stars, the platform implements agentic research planning where language models decompose queries, select appropriate tools, retrieve information in parallel, and synthesize responses with inline citations. Seventeen distinct search modes cover Web, Academic, Extreme, X (Twitter), Reddit, GitHub, Stocks, Crypto, YouTube, and Prediction markets, each activating a curated subset of the 28 built-in tools. The Extreme mode deploys a deep research agent with multi-step planning, parallel source retrieval, code execution in sandboxed Daytona environments, and R2 artifact storage for generated charts.

The web search tool supports Exa, Tavily, and Firecrawl as interchangeable providers via a Strategy pattern. Lookouts schedule recurring research agents on cron schedules that monitor topics, track changes, and email summaries using Upstash QStash for reliable execution. PostgreSQL stores chat history, user preferences, and custom instructions while Redis handles caching and rate limiting. 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.

Paste one SQL query result into a browser and get an interactive entity-relationship diagram instantly, with no installations, no credentials, and no account required. ChartDB's "Smart Query" runs a single statement in your existing database client that exports table definitions, relationships, indexes, and column types as JSON metadata, meaning the application never touches your database passwords. The canvas renders draggable entities with cardinality markers, collapsible grouping areas, and sticky notes for documentation. AI-powered DDL export generates migration scripts between dialect pairs like PostgreSQL to MySQL or SQLite to CockroachDB, analyzing your schema to produce target-specific DDL with correct type mappings and constraint translations. Import paths cover Smart Query JSON, raw DDL scripts, and DBML files from tools like dbdiagram.io. The AI layer connects to OpenAI or any compatible inference server including local vLLM instances running models like Qwen2.5-32B. Database coverage includes PostgreSQL (with Supabase and Timescale extensions), MySQL, SQL Server, MariaDB, SQLite (with Cloudflare D1), CockroachDB, ClickHouse, and Oracle. Exports to SVG with inline styles or SQL DDL in any target dialect. Ships as a React/Vite frontend behind Nginx in Docker, deployable on RepoCloud with dedicated VPS resources under the AGPL-3.0 license.
