Frappe LMS is a learning management system built on the same Frappe Framework that powers ERPNext. The 3-level course hierarchy organizes content into courses, chapters, and lessons supporting videos, PDFs, SCORM packages, and rich HTML content with heading, code block, and list formatting through the redesigned inline lesson editor. Batch management groups learners by course and duration with scheduled instructor-led live sessions through integrated Zoom and Google Meet, where learners see upcoming classes on their batch dashboard. The assessment engine supports single-choice, multiple-choice, and open-ended quiz questions alongside assignment submissions as PDFs or documents, with progress tracking monitoring completion rates and quiz performance across all enrolled courses. Certificate generation uses built-in templates or custom designs to validate course completion, while the job board connects certified learners with opportunities. Course monetization integrates payment processing to transform courses into revenue streams with financial tracking. Role-based access controls assign Instructor, Learner, Admin, and Manager permissions, while course package import and export enables sharing structured content between instances. The platform integrates with ERPNext HR and CRM modules through the Frappe ecosystem with RTL language support and notification slide-overs.

Receipts, contracts, and letters that arrive as pixels rather than text: Papermerge is a document management system built specifically for scanned documents. Upload a PDF, TIFF, JPEG, or PNG and OCR runs automatically, with a real-time status indicator beside the document title; under the hood it drives OCRmyPDF and Tesseract, supporting 130+ languages and producing a new document version with a selectable, searchable text layer you can download. Full-text search runs across everything, with multiple search-engine backends (Xapian by default). The interface deliberately mimics a modern desktop file browser: dual-panel commander, drag and drop, hierarchical folders, and colored tags on documents and folders. Page management fixes what scanners get wrong - delete blank pages, rotate, reorder, merge, extract, and move strayed pages between documents, powered by PikePDF. Document types act as categories, each with its own custom metadata fields, so invoices carry vendor and amount while contracts carry parties and dates. Versioning preserves every state of a document. Multi-user support includes groups, group ownership, permission management, and document/folder sharing between users and groups, and an OpenAPI-compliant REST API automates ingestion from scanners or scripts. Apache-licensed, ideal for long-term digital archives.

For research teams that need to show what was recorded and when, eLabFTW® is an electronic lab notebook that keeps experiments, lab inventory, and equipment bookings in one shared, searchable system. Each experiment holds rich-text notes, tables, images, checkable steps, custom metadata fields, tags, statuses, and attached files. Templates turn a protocol you repeat into a one-click starting point. A separate resource database catalogs antibodies, plasmids, cell lines, chemicals, and instruments, and typing # in an experiment links straight to any of them. Compounds import from PubChem by CID or CAS number, arriving with formulas, identifiers, and hazard data. The inventory tree maps buildings and their sub-locations, records where each container is stored, and tracks quantity and unit. Book a microscope by dragging a slot on the scheduler, and permissions decide who may reserve what. Entries can be signed with Ed25519 keys and timestamped through RFC 3161 authorities such as DFN, Digicert, and GlobalSign, or anchored on the Bloxberg blockchain; a timestamp archive can never be edited or deleted. Export to PDF, ZIP, CSV, JSON, or .eln archives, and import .eln or CSV files when moving from spreadsheets or another notebook. Users sign in locally or through SAML2 or LDAP, and an API with per-user keys lets instruments and scripts read and write entries.

Trusted by Mistral AI, PayPal, Groq, and Synthesia with over 10,300 GitHub stars and Y Combinator backing, Lago is the open-source billing engine that handles usage-based, subscription-based, and hybrid pricing models through a single API-first platform — replacing the need to build custom billing logic or depend on opaque SaaS pricing infrastructure. Real-time event ingestion via ClickHouse processes billable events with deduplication and multiple aggregation methods including count, sum, unique count, max, and weighted sum, while graduated pricing tiers, package-based billing, and percentage-based fees model any pricing strategy from simple subscriptions to complex marketplace commission structures. Automated invoice generation calculates charges according to configurable billing cycles with grace periods, proration for mid-cycle changes, and credit note issuance for refunds and adjustments. Prepaid credits enable pay-in-advance models where customers purchase credit blocks and draw down as usage accumulates, while entitlements tie feature access directly to billing plans for automated provisioning and de-provisioning. Payment orchestration integrates natively with Stripe, Adyen, and GoCardless with automatic retry logic, dunning workflows for failed payments, and multi-gateway routing. Revenue analytics provide cross-stream visibility into MRR, usage trends, churn, and revenue drivers through dedicated API endpoints. The customer portal embeds into your application for self-service invoice access and usage monitoring.

With over 8,000 GitHub stars and continuous development since 2020, LibrePhotos delivers the core intelligence of Google Photos — face recognition, object detection, semantic search, and automatic album generation — entirely on your own hardware without sending a single photo to a third-party server. The Django 5 backend processes uploaded media through a machine learning pipeline that runs face detection via the face_recognition library, clusters identified faces using scikit-learn and HDBSCAN, generates image captions through BLIP and Moondream 2, and classifies scenes using Places365 or Google's SigLIP 2 vision-language model with zero-shot classification against 900+ real-world tags. Semantic search lets you find photos by natural language queries like "sunset at the beach" without manual tagging, while metadata search filters by person, camera, lens, file type, and filesystem path. The React 18 frontend built with Vite presents a timeline view, fullscreen lightbox with slideshow mode, photo detail sidebar showing location and people, and a folder navigation view with breadcrumb paths. RAW files from any camera are converted via ImageMagick, videos processed through FFmpeg, and Live Photos paired with their RAW+JPEG counterparts as unified entries. Public album sharing via link provides fine-grained privacy controls, and duplicate detection uses perceptual hashing to identify near-identical images. Deployment runs as a single unified Docker container or via Docker Compose with Kubernetes manifests also available.

HFS turns any folder on a server into a file-sharing site that visitors open in a browser, with no upload step and no space or bandwidth cap beyond your own disk. Visitors browse, search, and download single files or whole folders as ZIP archives that start streaming immediately, and interrupted uploads or downloads can resume. A virtual file system lets you arrange and rename what is shared without touching the files on disk, while accounts and per-folder permissions decide who can see, download, upload, or delete. The admin web panel covers HTTPS with built-in certificate generation, bandwidth limits globally or per IP address, geographic blocking by country, and live connection monitoring with disconnect and IP ban. Plugins add thumbnails, share links, LDAP, two-factor sign-in, download quotas, and notifications, and a few lines of JavaScript in the admin panel can change the look or the backend behavior without a restart. The front end speaks 27+ languages, works on phones, and includes a media player for audio and video. Typical uses include sending large files to friends without uploading them first, publishing a download area, and collecting uploads from visitors.

Salesforce's platform model, 100% open-source (Apache 2.0): Corteza is a Go/Vue.js low-code platform developed under a foundation, so there is no open-core bait to grow out of. The heart is Corteza Compose: namespaces contain applications, modules define record structures the way Salesforce objects do, and a drag-and-drop page builder assembles record pages, list pages, dashboards, and charts from configurable blocks. Automation comes from a visual, BPMN-style workflow engine plus JavaScript automation scripts, so cross-application business logic - approval chains, field updates, notifications - is configured rather than programmed. Granular role-based permissions reach down to individual modules, fields, and records, mirroring real organizational hierarchies. Corteza CRM ships as the flagship application built entirely on Compose: leads, accounts, opportunities, campaigns, and cases with a 360-degree customer view, covering most Salesforce standard objects - and because it is just a Compose app, adding or reshaping modules is configuration, not a fork. Everything is reachable over REST APIs, deliberately familiar tooling eases Salesforce admin migration, and a CLI can even generate synthetic records for load-testing what you build.

Every scan and PDF you drop into Teedy becomes searchable text in a self-hosted document archive, filed by nested tags instead of folders. OCR reads images in more than twenty languages, and the search box offers suggestions and highlights matches, even inside ODT, DOCX, and PPTX files. Video files are supported as well. Each record carries Dublin Core fields plus custom metadata of your own design, with comments and earlier file versions attached. When a document needs a second pair of eyes, workflow steps with assigned reviewers move it along in order until someone signs off. Pull in EML emails, let the server poll an inbox, or point the bulk importer at a whole folder, and incoming paperwork needs no manual filing. Share a single document through a public link, or keep it behind user and group permissions with a storage quota for each person. LDAP and two-factor authentication guard sign-in, 256-bit AES encryption protects stored files, and an audit log records who changed what. Webhooks alert other services, a documented REST API lets scripts take part, and an Android client carries the archive on a phone.

Tracking over 50,000 fleet vehicles across production deployments, Fleetbase delivers a modular logistics operating system where each module—Fleet-Ops, Storefront, Pallet, and Ledger—works independently yet shares a unified data layer that eliminates middleware between ordering, dispatch, warehousing, and accounting. The Fleet-Ops core handles real-time driver tracking through a SocketCluster-based WebSocket event bus, interactive map-based dispatch with both directed and ad-hoc driver assignment, configurable order workflows with custom rules, automation triggers, and activity flows, plus a Kanban-style order board for visual pipeline management. Service zones let dispatchers define geographic operating areas, while proof-of-delivery capture and route optimization close the last-mile loop. The Storefront module provides headless e-commerce with products, carts, and checkout that feed directly into dispatch queues, and the Ledger module records invoices and financial journal entries across all operations. The Navigator driver app—also AGPL-3.0 licensed and fully white-label—delivers turn-by-turn navigation, live order communication, and fault reporting to drivers in the field. The extension architecture pairs backend Laravel Composer packages with frontend Ember Engine modules, enabling third-party developers to build first-class platform extensions without forking. A RESTful API with full documentation, webhook delivery via Redis-backed queues, and push notification support through APNs and FCM round out the integration surface.

Termix delivers a unified, self-hosted infrastructure control center that consolidates SSH terminals, remote desktop streaming, and fleet automation into an intuitive browser workspace that replaces proprietary tools like Termius. Administrators connect to Linux servers and desktop environments using embedded RDP, VNC, and Telnet protocols powered by Apache Guacamole without requiring local client installations. The multi-panel terminal interface supports four-way split screens, allowing operators to broadcast keystrokes simultaneously across multiple production hosts or execute saved reusable script snippets with dynamic parameters. Real-time multiplayer session sharing lets engineers invite teammates via secure, time-limited links with configurable read-only or collaborative write permissions for troubleshooting incidents. Advanced networking layers handle SSH jump hosts, SOCKS5 proxy chains, Warpgate relays, and port knocking sequences to access segmented private networks securely. Integrated SFTP file managers provide drag-and-drop file transfers with editable path bars, inline text editing, and folder synchronization across remote machines. Background telemetry monitors CPU loads, memory utilization, disk IOPS, and container statuses, while built-in session recording captures complete terminal sessions for compliance auditing.

Navigating organizational knowledge, visualizing concept graphs, and orchestrating cooperative AI agents converge inside Yuxi, an open-source multi-tenant workspace built for enterprise research and deep archive exploration. Users can upload diverse business documents including scanned PDFs, spreadsheets, and slide presentations to automatically extract structured text blocks, tables, and entity relationships for semantic querying. Knowledge teams can inspect interactive topological graph views to explore connections between company entities, cross-referencing subgraphs against original file sources. Practitioners can configure autonomous agents with specialized subagents, assigning dedicated roles for concurrent research, deep data synthesis, and code execution. Human reviewers can inspect agent thought chains in real time and evaluate interactive confirmation cards before agents execute irreversible external actions or modify shared workspace files. Operators can execute sandboxed tasks that produce downloadable reports, interactive data charts, and rendered HTML pages stored within isolated workspace file systems. Administrators can govern model endpoints, set granular permission boundaries across departments, and monitor token consumption through live system analytics.

'Can Maria edit this document?' is a simple question with a hard implementation, and SpiceDB is the open-source, Zanzibar-inspired database built to answer it and millions like it correctly. You model your product once in its schema language, defining object types like documents and organizations, relations like owner and member, and computed permissions built from unions, intersections, exclusions, and arrows through other objects. Your application then writes relationships as users join groups, create folders, and share files, and SpiceDB evaluates checks against that live graph in milliseconds. Check a single permission before rendering a button, check hundreds at once to filter a dashboard, look up every resource a user can open for search prefiltering, or list every subject who can access a file for an admin screen. Per-request consistency options, anchored by revision tokens, protect you from the classic race where a revoked user briefly keeps access, and caveats add conditional rules based on context like IP address or time. Relationships persist in PostgreSQL for simple deployments or CockroachDB and Spanner when you need multi-region scale, and the same schema files validate in CI with the command-line tool before they ever reach production.

uMap turns OpenStreetMap into a personal mapmaking canvas: draw markers, lines and polygons in the browser, layer your own data over detailed street maps, and embed the finished map in any website. Each map is built from data layers you can style independently, choosing marker shapes, colors, icons and popups that show names, descriptions, photos or videos when clicked. You can sketch points of interest by hand or batch import whole datasets in GeoJSON, GPX, KML or OSM format, then let clustering group dense markers or a heatmap reveal where things concentrate. Backgrounds come from a choice of OpenStreetMap based tile layers, so the same map can sit on a street plan or a cycling map depending on the audience. Finished maps embed with a snippet of HTML, stay interactive inside the page, and can be downloaded or shared by link with read only access for viewers. Permissions decide who owns, edits or only views each map, and with real time collaboration switched on, several editors can draw on the same map simultaneously and watch each other's changes appear live. A slideshow mode turns layers into a guided story, stepping viewers through places in order with text and media attached to each stop.

Originally built at Netflix to orchestrate microservices powering 230 million subscribers and now trusted in production at Tesla, LinkedIn, and J.P. Morgan, Conductor is the most battle-tested open-source workflow engine available — with 32,000 GitHub stars and horizontal scalability to billions of executions. The architecture cleanly separates orchestration from business logic: workflows are defined in declarative JSON while workers execute tasks in any of seven supported languages (Java, Python, Go, JavaScript, C#, Ruby, Rust) with zero framework constraints. Durable execution persists every state transition, enabling automatic retries, configurable timeouts, crash recovery, and instant replay from any failure point without re-executing completed tasks. Native AI agent orchestration supports 14+ LLM providers (Anthropic, OpenAI, Google Gemini, AWS Bedrock, Mistral, Cohere, HuggingFace, Ollama), MCP tool calling, function calling, human-in-the-loop approval gates, and vector database integration (Pinecone, pgvector, MongoDB Atlas) for RAG pipelines. Deploy with your choice of five persistence backends (PostgreSQL, Redis, MySQL, Cassandra, SQLite), six message brokers, and Elasticsearch or OpenSearch for workflow indexing — all configurable via Docker Compose files included in the repository. The built-in web UI provides workflow visualization, execution monitoring, task queue inspection, and manual intervention controls.

Keep is an open-source AIOps and alert management platform built with Python FastAPI and Next.js. It provides a single pane of glass for monitoring alerts from 110+ integrations, alert deduplication, correlation, enrichment, and filtering, YAML-based workflow automation similar to GitHub Actions, AI-powered correlation and summarization, and customizable dashboards for incident management. With 12,100+ GitHub stars, Y Combinator backing, and an Elastic partnership, Keep is the open-source AIOps platform that centralizes alert management across your entire monitoring stack into a single customizable dashboard. Alert deduplication identifies duplicate notifications across providers, correlation groups related alerts into incidents based on rules or AI-powered semantic analysis using pluggable LLM backends supporting OpenAI, Anthropic, and local models via Ollama, and enrichment adds context from external sources like CMDBs and databases. Workflow automation follows a GitHub Actions paradigm with declarative YAML files defining triggers, conditions, and actions that can query MySQL, update Jira tickets, send Slack messages, execute Python scripts, or call REST APIs. Authentication supports no-auth, database, Auth0, Keycloak, OAuth2 Proxy, Okta, and OneLogin. The Common Expression Language enables advanced alert querying, slicing, and rule-based grouping to reduce noise. On RepoCloud, deploy Keep on a dedicated VPS with Docker Compose, root SSH access, and complete control over your alert infrastructure, all under the MIT license.

Configure each indexer once, not five times: Prowlarr is the indexer hub of the *arr stack, removing the most tedious duplication in a media automation setup. Instead of configuring the same torrent trackers and Usenet indexers separately in Sonarr, Radarr, Lidarr, Readarr, and Mylar3, you add each one once in Prowlarr and it syncs them to every connected app automatically, complete with category mappings; with Full Sync enabled, adding or removing an indexer propagates everywhere, and a tracker URL change is a one-place fix. Coverage is the deepest available: 500+ torrent trackers with definitions added constantly, 24 native Usenet indexers, generic Newznab and Torznab support for anything else, and custom Cardigann YML definitions with JSON and XML parsing for obscure sources. Built on the same .NET/React base as its siblings, it also earns a place as a search tool in its own right: unified manual search queries every indexer simultaneously at a category level, and you can push multiple releases straight to your download clients without touching Sonarr or Radarr. Health checks and status notifications flag failing indexers, per-indexer statistics track success rates and response times so you can cull unreliable sources, and per-indexer proxy support (SOCKS4/5, HTTP, FlareSolverr) handles trackers behind Cloudflare.

Leave balances, timesheets, and employee files tend to scatter across spreadsheets as a company grows; OrangeHRM pulls them into one human resources system that runs entirely on your own server. Human resources staff keep a complete record for every employee, from contact details and job history to documents, dependents, and custom fields the organization defines. Employees request vacation, sick days, or any leave type you configure, and supervisors approve or reject each request against live entitlement balances instead of counting days by hand. Timesheets and punch-in, punch-out attendance records show who worked on which project and for how long, turning payroll preparation into a review step instead of an investigation. When a position opens, vacancies are published, applications collected, and candidates moved through screening, interviews, and offers with every comment kept on the candidate record. Performance reviews run on scheduled cycles with goals and appraisals recorded per employee, so annual reviews stop depending on whoever kept the best notes. Administrators shape the system around the company itself: organization structure, job titles, pay grades, locations, user roles, and the logo and colors employees see at login. Built-in reports answer everyday questions, like whose contracts end this quarter or which department used the most leave, and the directory gives everyone a searchable view of who does what.
