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.

With over 11,200 GitHub stars and adoption by France's sovereign digital workspace LaSuite serving 20,000+ government users, Grist is the relational spreadsheet that ends the false choice between fragile Excel files and expensive custom database development — storing all data in portable SQLite files while providing true relational structure where VLOOKUPs become actual linked records that update instantly across entire documents. Python-powered formulas replace complex Excel syntax with clear, readable logic using the full Python standard library, while familiar Excel functions remain available for users who prefer them. Granular access rules control permissions at row, column, table, and cell levels — not just entire sheets — enabling multi-department documents where each team sees only their authorized data. The flexible layout system combines spreadsheets, card views, charts, calendars, and custom widgets on configurable dashboard pages that transform raw data into operational interfaces. Real-time collaboration lets multiple users edit simultaneously with automatic snapshot history capturing every change for full audit trails and point-in-time recovery. AI formula assistance connects to OpenAI, Llama, or any OpenAI-compatible endpoint via OpenRouter to generate formulas from natural language descriptions. The REST API and webhooks enable integration with n8n, Zapier, and custom automation, while incremental imports keep external data sources synchronized. Deployable via Docker with OIDC, SAML, and SCIM authentication support. 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.

Confluence and Notion both want your team's documentation in their cloud; Docmost, an open-source collaborative wiki platform, keeps it on your server. The centerpiece is a Notion-style block editor with CRDT-based real-time collaboration: multiple people edit the same page simultaneously and changes merge without conflicts or overwrites. Content lives in spaces - per team, project, or department - with nested page trees, role-based permissions, groups, inline comments, page history with restore, and full-text search across everything. The editor covers tables, code blocks, callouts, KaTeX math, and file attachments, and diagramming is built in rather than bolted on: Mermaid, Draw.io, and Excalidraw all render inside pages, alongside embeds for Airtable, Loom, Miro, and more. Migration paths include Notion, Markdown, HTML, and ZIP archive imports (Confluence, PDF, and DOCX importers ship in the Enterprise edition, along with SSO via SAML/OIDC/LDAP and MFA). The stack is TypeScript with PostgreSQL and Redis, deploys via Docker Compose, runs in air-gapped environments with no external dependencies, and is translated into 10+ languages. The AGPL-3.0 community edition carries no per-seat fees; the project has passed 20,000 GitHub stars since its 2024 launch.

Gaining over 71,000 GitHub stars as one of the fastest-rising knowledge management platforms, AFFiNE merges the document editing capabilities of Notion, the infinite canvas of Miro, and the structured data of Airtable into a single cohesive workspace. The block-based editor built on the custom BlockSuite framework supports rich text, code blocks, embeds, tables, kanban boards, and database views with drag-and-drop composition. The whiteboard mode provides an infinite canvas where users can freely mix documents, sticky notes, shapes, connectors, and hand-drawn elements, enabling visual thinking alongside structured note-taking. Real-time collaboration allows multiple users to edit documents and whiteboards simultaneously with cursor presence, comment threads, and version history. The local-first architecture stores all data on your device by default using CRDT-based synchronization, ensuring offline access and data sovereignty, with optional cloud sync for cross-device availability. Workspaces organize content into hierarchical page trees with full-text search, favorites, tags, and trash management. The platform supports Markdown import and export, PDF export, and HTML export for interoperability. AI features powered by configurable LLM providers enable writing assistance, summarization, translation, and content generation directly within documents. The theming system supports light and dark modes with customizable accent colors. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Licensed under MIT with an open-source self-hosted edition.

TREK coordinates group expeditions and vacations through a collaborative travel planning workspace that unifies daily itineraries, interactive route maps, shared expense budgets, and packing lists. Travel groups can build day-by-day timelines by dragging activities between dates, attaching transit bookings with flight numbers, and estimating driving intervals directly on OpenStreetMap and Mapbox canvases. Instant WebSocket synchronization mirrors itinerary edits, group chat messages, and decision poll votes across all traveling companions simultaneously without page refreshes. The integrated multi-currency expense manager tracks shared expenditures across lodging, dining, and transit categories, automatically calculating per-person debts and generating simplified debt settlement summaries. An interactive world atlas highlights visited nations and tracks lifetime travel statistics, enabling globe-trotters to manage personal bucket lists and review past journeys. Travelers can organize shared packing checklists from reusable equipment templates, monitor real-time weather forecasts powered by Open-Meteo, and export comprehensive travel schedules to printable PDF guides and calendar feeds. Role-based permission controls safeguard sensitive travel documents and boarding pass uploads while allowing guests to contribute notes and vote on activities. 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.

With over 14,000 GitHub stars and a mission to become the world's most trusted document-signing tool, Documenso delivers a beautifully designed electronic signature platform that organizations can self-host for complete data sovereignty. The signing workflow handles everything from simple one-party signatures to complex multi-recipient documents with configurable roles including signers, approvers, viewers, and CC recipients, each with distinct permissions and notification flows. Document templates enable reusable signing packages with pre-configured fields and recipient patterns, eliminating repetitive setup for contracts, NDAs, and onboarding documents that teams process regularly. The PAdES-standard implementation ensures digital signatures are legally compliant and cryptographically verifiable, with complete audit trails documenting every action from document creation through final signature. Direct link signing allows recipients to access documents without email, enabling embedded signing experiences within existing applications and websites. The REST API provides programmatic document creation, recipient management, and webhook notifications for integrating signature workflows into CRM systems, HR platforms, and custom business applications. Team management features organize users into groups with role-based permissions, custom branding per team, and centralized billing for organizations with multiple signing workflows. SSO integration supports standard authentication providers for enterprise identity management. The TypeScript codebase built on Next.js and Prisma with PostgreSQL makes customization and contribution accessible to modern web developers. Zapier integration connects Documenso to thousands of third-party applications for automated document routing. Deploy 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.

Open the page, write a Markdown note, move on - Memos is a lightweight, self-hosted service built for quick capture. Instead of folders, notebooks, and titles, it presents a timeline: open the page, write a Markdown note, and move on. Notes support headings, code blocks with syntax highlighting, task lists, tables, and file attachments, with tags auto-extracted from #hashtags in the text. Each memo carries a visibility level, private, protected (logged-in users), or public, so one instance works as a personal log, a small team wiki, or a lightweight microblog. The backend is a single Go binary with a React frontend, around 50 MB of memory at runtime and a ~20 MB Docker image, so it fits comfortably on the smallest instance size with near-zero maintenance. SQLite is the default store, with MySQL and PostgreSQL supported for multi-user deployments needing more concurrency, and full REST and gRPC APIs - Connect RPC for browsers, gRPC-Gateway for external tools - make capture scriptable from CLIs, bots, and automation platforms. Fast full-text search spans all memos, pinned notes keep references handy, and a masonry view suits visual browsing. MIT-licensed with zero telemetry; content is stored as plain Markdown in a database you control, so notes remain readable, exportable, and free of proprietary formats.

Designed as a unified personal AI workstation, QwenPaw operates as an autonomous digital copilot that coordinates scheduled automations, interactive coding sessions, and multi-channel team communication across everyday messaging apps. Users can dispatch long-running research tasks, process office documents including PDF, Excel, and Word files, and execute browser-based data collection without manual intervention. The built-in web console and terminal interface provide full visibility into agent reasoning, allowing operators to inspect intermediate thinking steps, review proposed file edits, and approve sensitive tool calls. Through direct connectors for Discord, Telegram, DingTalk, Lark, and WeChat, teams can trigger specialized skills or query shared workspaces directly from their existing group channels. A self-evolving personal memory system continuously indexes chat interactions and local resources into editable Markdown files, ensuring knowledge persists across restarts and task delegations. Built-in guardrails including a sandboxed execution runtime, tool access policies, and automated skill scanners protect underlying host files from unauthorized modifications during autonomous scripting runs. 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.

Small teams do not need another cloud subscription to know who is doing what this week: Work-Calendar runs your whole plan, do, finish, archive loop on one little server you own. The week view lays out every member's tasks across seven day columns with today highlighted, so standups start from the same picture instead of five private lists. Three kinds of tasks cover real work: project tasks, one-off tasks you can assign to yourself or teammates, and fixed recurring tasks on daily, weekday, monthly, or specific-date schedules. Anything unfinished carries over to the next day automatically, and completion records can be corrected by the assignee or sent back with a reason by the owner. Projects get spaces with folders, files up to 20MB, meetings with AI-generated minutes from pasted or dictated transcripts, timelines, and closing reports that an admin approves. Roles for superadmin, admin, and member, plus per-group rules, decide who may create projects directly, who needs approval, and who can use the built-in AI assistant, which drafts task and project changes as reviewable cards rather than acting silently. Inbox notifications, personal diaries, and daily statistics round out the routine, and keyboard shortcuts drive the whole interface. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

The file is on your laptop, the laptop is downstairs, and cloud drives are still syncing yesterday; Local Content Share ends that dance by giving every device on your network one shared page on port 8080. Type or paste a snippet and it appears instantly on your phone, tablet, and work machine, because Server-Sent Events push every upload, edit, and deletion to all open browsers without a refresh. Files ride along three ways: pick them, drag several at once onto the text area, or paste straight from the clipboard, screenshots included. A separate notepad holds Markdown with edit and preview modes, auto-saving as you type so a thought started on the couch continues at the desk. Links get their own newest-first section, everything can be renamed or edited in place, and each item carries an expiration clock you can set to an hour, a day, or a custom span like 34m or 2w, after which it quietly deletes itself. The interface follows your system light or dark theme, installs as a phone PWA, and needs no accounts and no internet, which is also the honest catch: there is no login, so keep it on trusted networks or behind an authenticated proxy. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

One statically-compiled Go binary over PostgreSQL, no ORM, no framework, static assets embedded in the executable: Miniflux is the minimalist, opinionated feed reader. The opinions are the feature: page layout, fonts, and colors are tuned for reading, and everything else is treated as noise. It consumes Atom, RSS, and JSON Feed formats with OPML import/export, organizes articles with categories and bookmarks, fetches original full-text content for summary-only feeds, and provides Postgres-powered full-text search. Privacy work happens automatically: pixel trackers are stripped, tracking parameters removed from URLs, a media proxy blocks third-party tracking, referrers are never forwarded, and there is zero telemetry. Navigation is keyboard-first - j/k through items, o to open, f to star - with touch gestures on mobile. Podcast, video, and music enclosures are supported, and YouTube videos play inline. Over 25 integrations save articles onward to Wallabag, Readwise Reader, Pinboard, Linkding, Instapaper, Notion, Telegram, Matrix, Ntfy, and more, plus webhooks and a REST API with Go and Python clients; the Google Reader API endpoint supports existing mobile reader apps. Authentication spans local passwords, passkeys (WebAuthn), Google OAuth2, OpenID Connect, and reverse-proxy headers. It is Apache 2.0 licensed, translated into 20 languages, and updates feeds on an internal scheduler.

The ad-riddled "free online tools" sites people paste sensitive text into and upload confidential PDFs to - OmniTools replaces that whole ecosystem with one self-hosted app. It bundles 50+ utilities behind one clean React/TypeScript interface: image tools (resize, convert, crop, edit), video and audio tools (trim, reverse, convert), PDF tools (split, merge, edit), text and list utilities (case converters, formatters, shufflers), plus date/time, math, and data-format helpers for JSON, CSV, and XML. The architectural decision that makes it trustworthy is that all file processing happens entirely client-side in the browser - the server only serves static assets, and nothing you process ever leaves your device. That design has a pleasant side effect: the host needs almost no resources (people run it on a Raspberry Pi Zero), because your browser does the work while the server just delivers files. The Docker image is a remarkable 28 MB, making it one of the fastest apps to deploy and cheapest to keep running. There are no ads, no tracking, no accounts, and no upload limits. With multi-language support and an MIT license, it works equally well as a personal toolbox or a team-wide internal utility portal - one URL that replaces a bookmark folder full of questionable converters. Actively developed with 50 contributors and 9,500+ GitHub stars.

Contracts signed on your own server: DocuSeal is the most feature-complete open-source, self-hosted alternative to DocuSign. A WYSIWYG builder turns any PDF into a fillable form with 14 field types: signature, initials, date, file upload, checkbox, dropdown, radio, stamp, and more. Documents route to multiple submitters in sequence or parallel, with automated SMTP email notifications, reminders, and a mobile-optimized signing experience that works on any device without an account. Every completed document carries an automatic PDF eSignature with verification and an audit trail. Templates are reusable and can also be generated programmatically - from HTML via API or from PDFs and DOCX files with embedded field tags - and the REST API plus webhooks drive full workflow automation, with embedded signing forms and form builders for React, Vue, Angular, and plain JavaScript. Files store on disk or in S3, Google Cloud Storage, or Azure. The UI ships in 7 languages with signing in 14. Runs on SQLite, PostgreSQL, or MySQL; AGPL-3.0 licensed with unlimited documents and no per-signature fees.

Two decades of continuous development made Roundcube the standard-bearer of open-source webmail - a PHP IMAP client that gives any mail server a polished, application-like interface in the browser. It connects to whatever IMAP/SMTP stack you run - Dovecot, Postfix, a hosted mailbox - and delivers the full desktop-client experience: drag-and-drop message management, threaded conversation views, full MIME and HTML mail handling, find-as-you-type address book with groups and LDAP connectors, multiple sender identities, full-text search, and spell checking in dozens of languages. The default Elastic skin is genuinely responsive, working as well on a phone as a desktop, and the entire UI is skinnable. The plugin API is where deployments get shaped: managesieve exposes server-side filter management in the UI, enigma brings PGP encryption and signing via GnuPG, markasjunk trains spam filters, zipdownload batches attachments, password lets users change credentials, and attachment_reminder catches the classic forgotten-attachment email - among hundreds of community plugins. Built-in caching keeps large mailboxes fast, IMAP ACLs and shared folders support team setups, and XSS protection is engineered into the rendering pipeline. It scales from a single personal mailbox to unlimited users, backed by MySQL, MariaDB, PostgreSQL, or SQLite. GPL-licensed with regular security releases.

"As simple as Trello but as feature-rich as Jira" is how the Leantime team frames its goals-focused project management system for non-project managers - built from the ground up with ADHD, autism, and dyslexia in mind, with behavioral science shaping customizable dashboards, time blocking, low-cognitive-load prioritization, and Kanban, list, table, Gantt, and calendar views so each person works the way their brain does. The PHP application (AGPL, Laravel Blade frontend) connects strategy to execution: tasks with unlimited subtasks and dependencies roll up into milestones on a timeline, sprints and retrospectives handle iteration, and strategy-level blueprint boards - Lean Canvas, SWOT, risk analysis, goal and metric tracking - keep the "why" attached to the work. Knowledge lives alongside: wikis and docs, idea boards, comments on everything, file storage on S3 or local disk, even screen and webcam recording. Time tracking with timesheets supports estimation and client billing. Admin features are serious for an OSS tool: per-project permissions, two-factor auth, LDAP and OIDC single sign-on, Slack, Mattermost, and Discord integrations, a plugin system, and an expanding API that now powers a mobile app. Recent releases added multi-collaborator task assignment and low-vision accessibility improvements. Available in 20+ languages.

Your calendars and contacts do not need a cloud account, and Baikal is the small PHP server that keeps them on hardware you control while still syncing to every phone and laptop you own. The web admin panel is where you add users, create their calendars and address books, and reset passwords, no database editing or config files required. Each person signs in with their own username and password, so an iPhone, an Android phone running DAVx5, and a Thunderbird desktop can all stay in sync without sharing one master credential. Standard well-known redirects mean most clients configure themselves when you type the server address, and the combined dav.php endpoint serves calendars and contacts from a single URL. Events carry the full CalDAV feature set your clients expect (recurring appointments, reminders, attendees, and free-busy lookups), while CardDAV address books keep names, phone numbers, and photos in one place. Because storage is a plain database file or table set, backups are a copy you can make in seconds, and moving to a bigger host is a file transfer rather than a migration project. The same server happily runs for one person tracking a family calendar or for a small office sharing team schedules and a company address book. 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.

Every morning, TLDR Radio converts the day's TLDR newsletters into chapterized podcast episodes you listen to instead of read, generated entirely on your own server. Pick a date at the Broadcast Desk, hit Broadcast, and a few minutes later chapterized episodes wait in your browser, one per newsletter with each story as its own track. All fourteen TLDR newsletters can sit on the Desk for manual runs, join the overnight build, or both, and the overnight selection shows an estimated listening time measured from your own episodes. Scheduled builds retry until the day's issue appears and can send an ntfy notification when the audio is ready. The player groups your library by day, shows each chapter with its section heading, source summary, and link to the original, and offers 15-second skips, playback speed up to 2.5x, auto-advance, resume, and keyboard shortcuts. Sponsor segments become their own clearly marked chapters in a different voice, announced out loud so an ad is never mistaken for news, and easy to skip. Sixty-eight voices can be auditioned in Settings, and every episode downloads as a single tagged MP3 with album, title, and author set for podcast and audiobook apps. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
