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.

The integrations your SaaS product offers its own users - that is what Nango, an open-source product-integrations platform, exists to build. It solves the repetitive infrastructure work behind every third-party API connection: OAuth flows, API key handling, token refresh, encrypted credential storage, rate-limit backoff, retries, and multi-tenant connection management. It ships pre-built auth configurations for 800+ APIs. Your users connect their accounts through an embeddable, white-label Connect UI, and your backend then reads or writes data through Nango's proxy, SDKs, or REST API without ever touching raw credentials. Integration logic is written as TypeScript functions covering actions, scheduled data syncs, and webhook processing - all running on one runtime with retries, checkpointing, and per-connection logs built in. Syncs pull records incrementally on a schedule, one-way or two-way, which suits RAG pipelines, search indexing, and keeping local copies of external data current. Selected actions can also be exposed as tool schemas or through a built-in MCP server, so AI agents operate on user-connected accounts without ever handling provider credentials. Auth support spans OAuth 2.0, OAuth 1.0a, API keys, basic auth, and JWT, and observability - logs, metrics, failure detection, and a reconnect flow for expired credentials - is scoped per customer connection for easier support debugging. Works with any backend language. Self-hosting on RepoCloud keeps all customer credentials and synced data on infrastructure you control, which matters for data residency and compliance requirements.

Mox offers a complete mail server stack in a single Go binary requiring no external dependencies. The quickstart command configures a working mail server with SMTP, IMAP4, webmail, and full DNS authentication in under ten minutes. SMTP handling includes a delivery server on port 25, a submission server for authenticated clients, and a queue with automatic retries and DKIM signing. IMAP4rev2 implementation provides full mailbox synchronization with CONDSTORE and QRESYNC for efficient offline clients, NOTIFY for multi-mailbox monitoring, MULTISEARCH across mailboxes, and TLS client certificate authentication via the EXTERNAL SASL mechanism. The built-in webmail provides browser-based reading and composing with message threading, attachments, and HTML rendering without requiring a separate web client. Email authentication implements SPF validation, DKIM signing and verification with automatic key rotation, DMARC policy enforcement with aggregate and failure reporting, DANE with DNSSEC-protected TLSA records, and MTA-STS for certificate verification. Junk filtering combines reputation-based sender scoring with Bayesian content analysis trained per account. The web administration interface manages domains, accounts, DNS records, TLS certificates, delivery queue, and real-time log viewing. Internationalized email addresses with EAI and IDNA support handle non-ASCII domains and mailboxes. Account autoconfiguration publishes settings for Thunderbird autoconfig and Outlook autodiscover. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

What Jellyfin is for video, Komga is for comics, manga, BDs, magazines, and eBooks: point it at folders of CBZ, CBR, CBT, PDF, and EPUB files and it becomes a proper library with cover art, embedded metadata import, and per-user reading progress. The responsive web reader handles multiple reading modes - left-to-right for western comics, right-to-left for manga, webtoon scrolling - while collections and read lists organize crossovers and story arcs, with ComicRack .cbl read list import for existing curation. Its openness is the real differentiator: OPDS v1.2 and v2.0 feeds serve virtually every reader app (Panels, Moon+ Reader, Mihon/Tachiyomi, KyBook), with OpenSearch and page-streaming extensions so mobile apps fetch pages on demand instead of whole archives. E-ink support is built in, not bolted on - Kobo devices sync directly against Komga instead of Kobo's servers, with two-way read progress, on-the-fly KEPUB conversion via Kepubify, and optional proxying so official Kobo purchases still work; KOReader sync covers everything else. Multi-user management brings per-library access control, age restrictions, and label restrictions for family setups. Housekeeping tools detect duplicate files and duplicate pages, and a REST API feeds a healthy ecosystem of community scripts. Runs from a single Docker container with embedded SQLite.

With over 1,200 GitHub stars, 12,000+ commits, and more than a decade of active development distributed under the AGPL-3.0 license, Cozy Cloud operates as a comprehensive personal data hub that goes far beyond file storage by connecting your documents, contacts, calendars, banking transactions, energy bills, and productivity tools into a single self-hosted platform where no third party profiles you. The cozy-stack Go binary handles file storage, CouchDB document management, job scheduling, app serving, and the REST API in a single process consuming approximately 150MB of RAM idle. Sandboxed konnectors import data from 50+ external services — banks, utility providers, telecom operators, cloud drives — running as isolated jobs via nsjail to prevent untrusted code from accessing other user data. The built-in app store serves web applications in subdomain-isolated environments with Content Security Policy headers, each app communicating exclusively through the documented REST API. Real-time synchronization via PouchDB replication and WebSocket keeps files, contacts, and documents consistent across desktop clients, mobile apps for iOS and Android with automatic photo backup, and the web interface. Security features include automatic Let's Encrypt TLS certificates, Argon2id password hashing, optional TOTP two-factor authentication, and GDPR-compliant data export via the CLI. Each user receives their own isolated instance with independent storage, database, and application configuration. 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.

A deliberately simple ticketing system standing in for both Zendesk and Jira: Peppermint handles internal staff requests and external customer support alike. The stack is modern full-stack TypeScript: Next.js and React over Prisma and PostgreSQL, which makes it light to run and approachable for developers extending it. Ticket creation is straightforward - a markdown editor with file uploads, assignment, status tracking, and a logical workflow that new agents grasp without a manual. Mailbox integration converts email into tickets automatically: configure SMTP/IMAP per mailbox and incoming messages become trackable tickets. Each client accumulates an interaction history, giving agents context on every past request before replying. Two touches distinguish it from bare-bones ticketing: a built-in markdown notebook with todo lists for internal documentation and knowledge sharing, and OIDC authentication so agents sign in through your existing identity provider - Keycloak, Okta, Authentik, or Azure AD. Configurable webhooks and email notifications push ticket events to third-party services. The UI is responsive from mobile to 4K, and everything works fully offline in air-gapped environments. Docker-native and scalable via Kubernetes, with an active community of 3,000+ GitHub stargazers.

With 10,400 GitHub stars, 153 contributors, and no per-monitor pricing to worry about, Checkmate delivers comprehensive infrastructure monitoring from a single self-hosted dashboard — tracking uptime, page speed, server hardware, Docker containers, and even game servers without sending a byte of telemetry off your network. Ten monitor types cover HTTP, ping, TCP, gRPC, WebSocket, DNS, SSL certificate expiry, Docker container health, Lighthouse page speed with Core Web Vitals tracking, and game server status for over 100 server types including Minecraft and CS2. The Globalping integration enables geo-distributed monitoring from six continents, running ping and HTTP checks from Africa, Asia, Europe, North America, South America, and Oceania with results plotted on an interactive map. The optional Capture agent written in Go collects CPU, RAM, disk usage, temperature, and network metrics from any Linux, Windows, Mac, or Raspberry Pi host. Public status pages ship with four built-in themes and custom branding support, showing per-service uptime bars and incident history on a single shareable URL. Alert notifications reach teams through email, Discord, Slack, PagerDuty, Microsoft Teams, Telegram, Matrix, ntfy, Twilio SMS, and webhooks. Deploy via a single Docker Compose file requiring roughly 1 GB RAM — up and running in under five minutes on any Docker host. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPLv3 licensed.

With nearly 8,000 GitHub stars since its December 2024 launch, Kaneo has rapidly gained traction as the minimalist alternative to bloated project management platforms like Jira and Linear. Built on TypeScript with React and Hono, the interface strips away complexity to focus on execution — plan in list view, track in kanban board, and schedule on interactive Gantt chart timelines where dragging bar handles adjusts start and due dates with optimistic UI updates. Native GitHub integration synchronizes issues bidirectionally, links pull requests to tasks, and keeps product planning aligned with development execution without context switching. The built-in Model Context Protocol server at /api/mcp enables AI tools like Claude and Cursor to manage tasks, projects, and labels directly, while the official @kaneo/mcp npm package provides stdio access for local MCP clients. Authentication supports password, magic link, GitHub OAuth, and Google sign-in with organization-level access management. Rich text editing for task descriptions and comments, label-based initiative grouping, priority levels, assignee management, and due date tracking provide focused planning without ceremony. Deploy with the drim CLI for automatic HTTPS and database setup, Docker Compose for custom configurations, or Helm charts for Kubernetes clusters — all requiring just 2GB RAM and PostgreSQL. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Kuzzle ships a production-ready backend from day one: data storage with Elasticsearch search, real-time pub/sub notifications, user authentication, role-based permissions, and a multi-protocol API serving HTTP, WebSocket, and MQTT simultaneously on port 7512. Rather than rebuilding these standard features from scratch for each project, you get a ready-made backend that accepts connections from web applications, mobile clients, and IoT devices through one unified API surface. Elasticsearch provides persistent document storage with full-text search, geospatial queries, and aggregation pipelines, while Redis handles internal caching and memory storage operations. The Koncorde real-time engine powers pub/sub messaging and database notifications, enabling clients to subscribe to document changes with filter conditions that trigger instant updates when matching data is created, modified, or deleted. User management includes JWT-based authentication, role-based access control with granular permissions at the controller and action level, and pluggable authentication strategies via Passport.js. The extensible plugin framework allows developing custom business logic, additional authentication providers, storage connectors, and protocol handlers. Client SDKs for JavaScript, Dart, Kotlin, and C++ accelerate frontend development, while the Kourou CLI provides command-line API access and project scaffolding. The Vue.js Admin Console offers a web interface for managing indexes, collections, documents, users, profiles, and roles. Horizontal scaling through masterless cluster mode targets 99.99% uptime without single points of failure.

A Node.js server, a large shared canvas, and a URL - WBO (Whiteboard Ophir) is collaborative whiteboarding reduced to its essence. There are no accounts and no setup - to collaborate, you send someone the board's link, and every stroke appears for all connected users in real time over WebSockets, with cursor positions shared so you can see where collaborators are working. Board state persists automatically and continuously, so a diagram drawn in today's lesson is still there next week at the same URL. Boards come in three flavors: a public free-for-all, private boards with random unguessable names, and named boards with custom URLs shared by anyone who knows the name. The tools cover teaching and brainstorming needs - pencil, straight lines, rectangles, ellipses, text annotations, eraser, a full color palette with brush sizes - and boards export as SVG or PNG. Despite the simplicity, the server is production-minded: JWT authentication gates board access with granular capabilities (open, edit, and clear as separate permissions), rate limiting caps per-client message volume, reverse-proxy and subpath deployment are supported, and OpenTelemetry provides metrics, logs, and traces. It works on tablets and touch devices, speaks multiple languages, and consumes minimal resources. AGPL-licensed.

Wealthfolio is a portfolio tracker offering a complete wealth management platform where financial data never leaves your infrastructure. Built on Rust with an Axum HTTP server, Diesel ORM, and SQLite storage, paired with a React 19 and Vite frontend, version 3.6 tracks stocks, ETFs, mutual funds, crypto, and cash savings across unlimited accounts with unified holdings. The performance engine calculates time-weighted returns (TWR), internal rate of return (IRR), volatility, maximum drawdown, and benchmark comparisons against the S&P 500 and custom indices, scoped per-account or across the entire portfolio. Net worth tracking monitors assets including real estate, vehicles, collectibles, and precious metals alongside liabilities, with stale-valuation warnings for items not updated in 90+ days. The spending module categorizes transactions automatically, supports multi-currency credit cards, builds budgets with monthly targets and rollovers, and generates narrative insights. A built-in AI assistant answers portfolio questions, suggests asset classifications, and imports transactions conversationally — bring your own API key from OpenAI, Anthropic, or use local LLMs. The addon system provides sandboxed extensions with granular permission declarations across 16 capability domains. CSV import maps broker exports with per-broker recipes for Interactive Brokers, Schwab, Fidelity, and dozens more. Market data streams from Yahoo Finance with automatic currency conversion.

Stocks, ETFs, crypto, bonds, precious metals, and cash across every account and currency, in one privacy-first dashboard: Ghostfolio is open-source wealth management software. The deliberate design decision is no brokerage linking: positions enter by manual entry, CSV import, or the REST API, so your holdings never pass through a data aggregator. Performance is measured as return on average investment across Today, WTD, MTD, YTD, 1Y, 5Y, and Max timeframes, with benchmark comparison against indices like the S&P 500, dividend tracking, and allocation breakdowns by asset class, region, and sector. A static X-ray analysis flags concentration and other portfolio risks, and a FIRE calculator projects progress toward financial independence. Multi-currency support converts holdings using historical exchange rates, market data comes from Yahoo Finance and CoinGecko among other pluggable providers, and everything exports back out as CSV or JSON. Built with Angular and NestJS on PostgreSQL and Redis, shipped as Docker images for amd64 and ARM, with a mobile-first PWA interface, dark mode, and a distraction-free Zen mode. AGPL-licensed.

OpenFGA answers the question 'can this user perform this action on this resource?' in single-digit milliseconds, implementing Google's Zanzibar paper as a production-ready authorization engine adopted by Auth0, Grafana Labs, Canonical, Docker, Agicap, and Read.AI. The server exposes both gRPC and HTTP APIs for authorization queries including Check, ListObjects, ListUsers, Expand, and the high-throughput BatchCheck endpoint that deduplicates and processes multiple authorization decisions in a single request. Authorization models combine relationship-based access control with role-based and attribute-based patterns through a purpose-built DSL that supports contextual tuples, conditional relationship tuples with CEL expressions, and time-based filtering via the ReadChanges API. Storage backends include PostgreSQL 14+, MySQL 8, and SQLite in beta, with an in-memory adapter for development and testing. Official SDKs for Java, .NET, Node.js, Go, and Python provide type-safe client integration, while a Terraform provider enables infrastructure-as-code management of authorization stores and models. The built-in browser playground at port 3000 lets developers visually model authorization schemas, write relationship tuples, and test access control queries interactively before deployment. OpenTelemetry instrumentation integrates with existing monitoring infrastructure, and Helm charts simplify Kubernetes deployment. A VS Code extension provides syntax highlighting and validation for FGA model files, and GitHub Actions automate model testing in CI/CD pipelines. A CNCF incubating project with transparent governance. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

With 6,700 GitHub stars, 79 releases, and 40 contributors since its October 2023 launch, OpenSign delivers a fully free electronic signature platform that removes the per-envelope pricing and seat limits of commercial e-signing services. The React-based frontend provides a drag-and-drop interface for placing signature fields, initials, date stamps, text inputs, and checkboxes onto PDF documents, while the Parse Server backend built on Node.js handles document routing through configurable multi-signer workflows with sequential or parallel signing order. Guest signers authenticate via one-time-password email verification without requiring account creation, while registered users manage documents through OpenSign Drive — a centralized vault with folder organization and status tracking across draft, in-progress, completed, and declined states. Every signing action generates tamper-proof audit trails logging timestamps, IP addresses, email addresses, and phone numbers, culminating in a detailed completion certificate attached to the finished document. The REST API v1.2 exposes endpoints for document creation, template dispatch, self-signing, and real-time webhook notifications on document lifecycle events, with regional deployments available in US and EU. PDF templates with pre-placed widgets enable repeated dispatch to different signers in a single API call. Custom branding controls email invitation templates, signing page appearance, and completion certificate styling. Deploy via Docker Compose with MongoDB, Caddy reverse proxy, and automatic HTTPS provisioning. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3 licensed.

With 4,500+ GitHub stars and version 1.0.92 released August 2026, xyOps delivers a complete operations platform that unifies workflow automation, job scheduling, server monitoring, alerting, and incident response in one self-hosted system. The platform uses a distributed architecture where a central conductor coordinates lightweight xySat satellite agents running on Linux, macOS, or Windows worker nodes via persistent WebSocket connections. The visual workflow builder lets you chain events, triggers, actions, and monitors into multi-step pipelines with conditional logic, fan-out/fan-in parallelism, multiplex controllers for fleet-wide execution, and configurable resource limits. QuickMon provides per-second CPU, memory, disk, and network visibility streamed live to the web UI, while user-defined monitor plugins sample metrics every minute with time-series storage at hourly, daily, monthly, and yearly resolutions. Alert triggers evaluate expressions against live data and fire notifications via email, webhook, or custom actions, with full server snapshots attached showing every running process, network connection, and resource utilization at the moment of detection. Failed jobs and alerts automatically create tickets with linked logs, metrics history, and context for end-to-end incident tracking. The plugin marketplace supports extensions written in any language, and the Docker plugin enables container-based job execution. Deploy via Docker with persistent volumes on port 5522 for the web UI and 5523 for API access, running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
