BTCPay Server processes Bitcoin payments with zero transaction fees, zero monthly costs, and zero third-party custody of your funds. Payments settle directly from customer to your wallet through a full Bitcoin node that provides cryptographic proof of receipt without trusting any intermediary. Lightning Network integration through LND, Core Lightning, or Eclair enables sub-second confirmation at sub-cent fees, with Ride The Lightning providing web-based node management within BTCPay itself. The Point of Sale app creates storefronts with product catalogs, tipping, and QR code displays for physical retail, events, or web embeds. Hardware wallet support through BTCPay Vault connects Ledger, Trezor, and ColdCard for transaction signing, keeping private keys in cold storage while running a hot payment interface. Multi-tenant architecture allows multiple stores on one instance, each with isolated wallets, Lightning nodes, and user permissions. The Greenfield REST API exposes every function programmatically for headless operation, automated invoicing, and custom integrations. E-commerce connectors for WooCommerce, Shopify, Magento, and PrestaShop plug in alongside Zapier for workflow automation. Optional Tor hidden services expose the instance as an onion address for censorship resistance. The official Docker Compose stack handles Nginx reverse proxy, Let's Encrypt TLS, and optional Tor configuration on a dedicated RepoCloud VPS with guaranteed CPU, RAM, and SSD. MIT licensed.

Consolidate fragmented collections of digital novels, graphic novels, manga, and audiobooks into Grimmory, an open-source media library server that combines automated file sorting with rich in-browser reading environments. The server indexes diverse media formats including EPUB, MOBI, AZW3, FB2, PDF, CBZ, CBR, CB7, M4B, and MP3 files across isolated storage directories. Readers explore literature through specialized browser viewports that provide customizable typography, CFI highlight annotations, two-page comic spreads with right-to-left manga modes, and chapter-based audiobook playback with sleep timers. Automated BookDrop watch folders ingest incoming files, retrieving book covers, author biographies, and community ratings from Google Books, Open Library, and Amazon APIs. Dynamic Magic Shelves organize catalogs automatically using nested boolean rule trees that filter books by page counts, genres, release dates, or narrator identities without server reload overhead. External e-readers access media catalogs through standard OPDS feeds or native Kobo and KOReader synchronization endpoints that match documents by binary content hashes. Built-in email delivery sends formatted books directly to Kindle devices with a single click, while OpenID Connect authentication enforces granular multi-user library permissions. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPLv3 licensed.

One browser tab can hold every database you manage, from MySQL and PostgreSQL to MongoDB and Redis, so there is no separate client to install for each engine. Connections are unlimited, and each can use its own SSH tunnel or SSL certificates. Tables open in an Excel-like grid where you edit cells inline, filter rows with expressions, and sort by any column. The SQL editor offers schema-aware code completion, a formatter, a join helper that builds clauses from foreign keys, query parameters, and a history of past runs, while result sets appear in separate tabs that you can filter, sort, and export. ER diagrams chart tables and their relations. The table editor creates columns, keys, and indexes and previews the SQL before anything is applied. Import and export move data between databases and files as SQL, CSV, JSON, XML, NDJSON, Excel, DBF, or YAML. Administrators can preconfigure connections through environment variables, mark them read-only, and protect the interface with logins that carry per-user permissions. Light and dark themes, customizable keyboard shortcuts, and translations into many languages keep daily work comfortable.

Moodle gives teachers a place to build courses and learners a place to work through them, with quizzes, assignments, grading, and progress tracking on a learning platform you host yourself. Custom or weekly sections sit beside a course index, and Previous and Next buttons walk learners through activities in order. The activity chooser adds forums, wikis, glossaries, lessons, H5P content, and SCORM packages. Question banks can be shared across courses and track every edit, and quizzes combine calculated, ordering, and essay questions with due dates and Safe Exam Browser settings. Assignments offer in-browser PDF annotation, rubrics, and marking guides, and with a marking workflow several markers can leave separate feedback before grades are released. Peer assessment runs through workshops, competency frameworks feed learning plans, and Open Badges recognize achievement. With learning outcomes enabled, a course page lists each outcome beside the activities linked to it. Learners follow deadlines on a dashboard timeline, message classmates, and take course content offline in the official mobile app. Sign-in works through email self-registration, LDAP, Shibboleth, OAuth 2, or LTI, and enrollment through keys, cohorts, flat files, or PayPal. Administrators assign roles, build custom reports, and upload plugin ZIP files. AI actions can run on providers including OpenAI, Azure AI, Gemini, Ollama, and Anthropic Claude, and a course-level report shows how students use them. 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-or-later licensed.

Linux Update Dashboard is a self-hosted web app that lets you check and apply package updates across a whole fleet of Linux servers from one browser dashboard, over SSH, with no agent installed on any managed machine. It discovers each server's package managers, operating system, installed packages, reboot state, and distribution lifecycle, then lets you refresh, upgrade selected packages, run full upgrades, autoremove leftovers, cancel running work, or reboot remotely while watching real-time command output stream into the page. Groups with health badges and explicit priorities organize fleets for clear overviews and ordered Upgrade All batches that run as waves across eligible systems. An encrypted SSH credential vault stores reusable passwords, private keys, and OpenSSH certificates with AES-256-GCM, and you can view or edit repository source files through sudoedit with diff review and activity history. Cron-based schedules automate refreshes, updates, autoremove, reboots, and notifications for chosen systems, while alerts go out by email, Gotify, MQTT, ntfy.sh, Telegram, or webhooks, with Home Assistant MQTT discovery entities for every server. Sign-in supports passwords with optional TOTP, passkeys and WebAuthn, OpenID Connect SSO, and API tokens, and the interface speaks ten languages with dark and light themes and custom branding. Because this tool can run commands on your servers, keep it on trusted networks behind TLS, a reverse proxy, or a VPN.

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.

Bigcapital gives small and medium businesses a complete double-entry accounting, invoicing, and inventory management platform they can self-host for free, replacing the per-seat subscriptions of QuickBooks, Xero, and Wave. Every transaction records debits and credits across your chart of accounts, automatically generating balance sheets, profit and loss statements, trial balances, general ledger reports, journal entries, accounts receivable and payable summaries, cash flow analysis, inventory valuation, and inventory summary reports. Sales invoicing supports recurring schedules, customer payment tracking, estimate-to-invoice conversion, and configurable GST/VAT tax rates. Purchase invoicing handles vendor bills with expense categorization for payroll, rent, and operational costs. The inventory module tracks stock levels using FIFO and average cost methods, automatically adjusting quantities on every sale or purchase and providing reorder alerts. Multi-currency accounting converts transactions at real-time exchange rates and consolidates them under customer or vendor profiles with detailed currency reports. The platform deploys via Docker Compose with multi-tenant isolation giving each organization its own separate database, requiring as little as 2GB RAM for the complete production stack. A headless REST API with Postman collections lets developers embed the accounting engine into external applications for programmatic transaction management. Role-based permissions control access for team members and invited accountants across organizations.

Edi Life OS puts the habits, goals, projects, money, focus sessions, and notes that usually live in five separate apps into one calm dashboard on your own server. Start the day from an Overview that rolls focus, habit trends, goals, finances, and the week ahead into one readable score. Connect long-term goals to six life areas, drive progress from a checklist, a measure, or a habit you actually keep, and use weekly, monthly, or quarterly reviews to choose the next honest step. Log daily habits with streaks and monthly progress, run timed focus sessions with short and long breaks, and keep a history of the deep work you finished. Track expenses, income, budgets, debts, and credits in your chosen currency, including recurring entries that land straight in the ledger. Plan projects on draggable Kanban boards with labels, priorities, due dates, checklists, comments, and attachments, then see card deadlines and money dues together in one calendar. Capture Markdown notes with preview and export, pin sticky notes with colors and connections, and give each account its own private workspace, theme, and currency. Ask an AI assistant through the optional MCP server to read your dashboard, create goals, log habits, or record expenses through a token-protected API that never touches the database directly.

With 5,700+ GitHub stars and over a decade of active development since 2012, Zammad is the open-source helpdesk platform that unifies every customer communication channel — email, live chat, telephone, WhatsApp, Telegram, Facebook, SMS, and web forms — into a single ticket management interface backed by PostgreSQL, Elasticsearch, and Redis. Version 7.0 introduced native AI features including automated ticket categorization, priority assignment, and title rewriting via AI agents that plug into triggers, macros, and scheduler jobs, plus one-click AI ticket summaries and a writing assistant — all configurable with your choice of LLM provider: OpenAI, Anthropic, Mistral AI, Azure AI, Ollama for local models, or any custom OpenAI-compatible endpoint with full audit logging of every AI action. Define service level agreements with first response, update, and solution time tracking tied to business hours calendars, with automatic escalation notifications. The knowledge base provides multilingual FAQ management with internal and public visibility. Core workflows enable dynamic ticket masks with conditional field dependencies per group. Text modules let agents insert predefined responses via the double-colon shortcut, while macros execute multi-step actions with one click. Security includes two-factor authentication, S/MIME and PGP email encryption, and single sign-on via SAML or OpenID Connect. Integrations connect to GitHub, GitLab, Microsoft 365, LDAP with nested group support, and Exchange. Deploy via Docker Compose, Kubernetes with the official Helm chart, or DEB/RPM packages.

Product catalogs, help centers, and document archives all fail the same way: visitors type a few words, get the wrong results, and leave. Apache Solr is the search platform behind fast, relevant answers, returning ranked matches with faceted filters, highlighted snippets, spell suggestions, and geospatial distance in a single query. Index documents through HTTP updates or data import handlers, shape fields in the schema, and watch changes appear through near-real-time indexing without rebuilding the corpus. SolrCloud turns one index into a distributed collection: shards split large corpora across nodes, replicas copy each shard for failover and query load, and ZooKeeper coordinates configuration so every node serves the same schema. Dense vector fields store embeddings beside your text, and the KNN parser retrieves nearest neighbors through HNSW graphs, so semantic search runs in the same engine as keyword search instead of a second system. A combined query handler merges keyword and vector rankings with reciprocal rank fusion, and an enrichment processor can call language models at index time to tag or summarize documents as they arrive. Streaming expressions add analytics over results, from rollups and percentiles to joins across collections, while JWT authentication and authorization rules protect the admin console and APIs.

Building healthcare software usually means assembling a FHIR data store, an identity provider, audit logging, and clinical interfaces before any product code gets written, and Medplum ships all of it as one open-source platform. Every clinical record, from patients and encounters to observations, medications, and appointments, lives in a standards-based repository you can query through REST and GraphQL APIs with full search parameters. Sign-in and permissions come built in through OAuth, OpenID Connect, and SMART-on-FHIR, with access policies that control read and write rights down to the resource, compartment, and field level. The included web app lets your team browse and edit any resource, manage project users, clients, bots, and secrets, and review a complete audit trail where every read, write, and login is recorded. Bots run your TypeScript logic inside the platform when resources change, on schedules, or over HTTP, handling jobs like HL7 transforms, eligibility checks, and notifications without another server to operate. Subscriptions push real-time events to your services through webhooks or WebSockets with retries and signing, and projects partition data so each clinic or customer stays isolated on one deployment. Clinicians get ready-made interfaces for charting, scheduling, eligibility, and billing that you can fork and rebrand, while patients reach their records through portals and SMART health links.

Your documents change every day, and your RAG answers should change with them: Serviette keeps a chat and REST API continuously in sync with the files you point it at, no re-indexing jobs to remember. Point it at a local folder, Google Drive, S3 or MinIO bucket, SharePoint library, or even an FTP or WebDAV share, and edits, additions, and deletions flow into the index in real time. One YAML file, or the interactive wizard, chooses among eight vector databases, from embedded DuckDB with zero setup to pgvector, Qdrant, Milvus, Chroma, Weaviate, Pinecone, or MongoDB Atlas. Text, Office files, PDFs with tables, and scanned images are parsed and answerable by default, with audio and video joining when you add the keys. Embeddings can run fully locally with no credentials, and keyless answers simply quote the retrieved passages with their sources. The indexer and the stateless server scale independently, the server shards across workers with one config line, and both a ChatGPT-style web chat and a versioned /api/v1 retrieval API answer on the same port. A free license key from Pathway activates the engine, and benchmarks cover corpora up to 50 GB of text.

Gately keeps your domain names current, forwards ports, terminates HTTPS, and blocks hostile traffic from one admin console, so a server or home network needs no pile of separate gateway tools. Dynamic DNS updates records at Cloudflare, Alibaba Cloud, Tencent Cloud, DNSPod, Huawei Cloud, Route 53, OVHcloud, Gandi, Namecheap, DuckDNS, and other providers, finding the public address over IPv4 or IPv6 by URL, network interface, or command. Port forwarding relays TCP and UDP with port ranges, failover targets, connection limits, traffic statistics, and PROXY protocol, while SNI routing lets several services share port 443. Certificates are issued and renewed through ACME with DNS-01 wildcards or HTTP-01, then pushed to other hosts over SSH. Web services add per-domain reverse proxies, redirects, and static sites with HTTP/3, WebSocket, load balancing, health checks, rate limiting, caching, and sign-in through OIDC, GitHub, Google, or TOTP-protected shared users. A WAF running the OWASP Core Rule Set and fail2ban-style jails with trap ports and nftables bans guard the edge. Manage Docker containers and Compose projects with one-click upgrades and rollback, open SSH sessions with an SFTP file manager, run ping, traceroute, and speed tests, and receive alerts in Telegram, Discord, Slack, ntfy, or email. An audit log, config history with diff and rollback, encrypted backups, scoped API tokens, and Prometheus metrics round it out.

Respan Gateway is a single-binary LLM gateway that lets the SDK you already use call any AI model from any provider, translating between OpenAI, Anthropic, and Gemini API formats on the way through. Point an OpenAI, Anthropic, or Gemini client at it and you reach chat models on sixteen providers, plus any OpenAI-compatible endpoint of your own, with streaming, tools, images, and reasoning translated. Traffic control works the way operators think: name a route, send it to the cheapest or fastest provider, retry on failure, fall back to a second vendor, or hedge a slow call by racing another provider. Models that never had tools get them anyway, because MCP servers and built-in search, browsing, code, document, and memory tools run inside ordinary chat requests behind the gateway. Realtime voice crosses vendors too, with an OpenAI Realtime client able to talk to Gemini Live, alongside images, speech, transcription, embeddings, and video through one endpoint. A live request log in the web UI shows the client key, model, provider, status, tokens, cost, and latency of every call, so runaway agents and surprise bills are visible immediately. Everything is a plugin on one public Rust API, from routing and pricing to tracing, with examples for guardrails, PII masking, and billing. One TOML file configures keys, providers, routes, and tools, validates before it starts, and reloads on signal.

Redlib lets you read Reddit without an account, ads, or trackers, through a clean page served from a machine you control. Open any subreddit, user profile, or comment thread and the server fetches the content and relays every image and video itself, so your browser never talks to Reddit directly. Pages need no JavaScript, unless you opt in to HLS video playback with sound. Choose card, clean, or compact layouts, a wide interface, and one of more than a dozen themes, from Dracula and Nord to Gruvbox and Tokyo Night. Post and comment sorting, a search box scoped to the current subreddit, a wiki tab, and subreddit filters help you find and tame your feed. Subscriptions build a personal home page with no login. Spoilers and NSFW previews can be blurred or hidden, and an SFW-only mode blocks mature content for the whole instance. Optional RSS feeds let a feed reader follow subreddits. Links to removed posts open in a configurable undelete viewer. Operators set defaults through environment variables, add an instance banner, discourage search indexing, and route outbound traffic through an HTTP or SOCKS proxy. Settings live in a browser cookie and can be exported or imported between devices. 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 12,400 GitHub stars and adoption across enterprises processing billions of events daily, Redpanda delivers a complete Kafka wire protocol implementation in C++ that existing Kafka producers, consumers, Kafka Connect connectors, and Kafka Streams applications connect to without code changes — eliminating JVM garbage collection pauses and ZooKeeper coordination overhead through a single binary architecture built on the Seastar framework's thread-per-core model. The integrated schema registry supports Avro, Protobuf, and JSON Schema validation directly within the broker without separate infrastructure. Tiered storage automatically offloads cold data to object storage while maintaining seamless consumer access across the full retention window. Redpanda Console provides a web-based management interface for topic inspection, consumer group monitoring, schema management, and ACL configuration. Redpanda Connect extends the platform with 200+ pre-built connectors for data pipelines between databases, cloud services, and streaming systems. Exactly-once semantics with idempotent producers and transactional guarantees ensure data integrity for financial, healthcare, and compliance workloads.

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.
