InvenTree is an inventory management system for electronics manufacturers, makerspaces, and small-to-medium businesses. The hierarchical part categorization system organizes components into unlimited nested categories, while stock items tracked across cascading locations and sub-locations provide instant visibility into current inventory levels, with optional serial number tracking for individual item traceability and acceptance testing. Intelligent BOM management calculates sub-part requirements, validates availability against current stock, supports multi-format BOM upload including KiCad integration, and generates detailed bills of materials with full database enrichment. Build orders consume BOM-allocated stock to produce assembled parts with step-by-step work order tracking, while purchase orders manage supplier relationships with pricing history, lead times, and automatic stock receipt processing. The modern React frontend built with Mantine, TanStack Query, and Zustand provides responsive data tables, tree-select navigation, a preview drawer, and a snippet editor. The extensible plugin system supports 19 mixin types including BarcodeMixin for scanner integration, LabelPrintingMixin for Zebra and Brother printers, AppMixin for custom database tables, and ScheduleMixin for periodic background tasks. Companion mobile apps on Android and iOS provide barcode scanning and stock operations in the warehouse. Docker Compose deploys with PostgreSQL, MySQL, or MariaDB backends behind any reverse proxy.

With 7,400+ GitHub stars and a feature set that replaces seven separate SaaS subscriptions — Pingdom for monitoring, StatusPage.io for status pages, PagerDuty for on-call, Incident.io for incident management, Datadog for APM, Loggly for logs, and Sentry for error tracking — OneUptime delivers every tool your reliability team needs in a single open-source platform that is genuinely 100% open source under Apache 2.0 (not open-core). Uptime monitoring runs synthetic checks against websites, APIs, ports, SSL certificates, and DNS records from distributed global probes with configurable intervals and thresholds. Branded status pages publish automatically when monitors detect issues, notifying subscribers via email, SMS, webhook, or RSS without manual intervention during an outage. On-call scheduling routes alerts through escalation policies to the right engineer via phone call, SMS, push notification, Slack, or Microsoft Teams. The incident management workflow handles declaration, triage, communication, resolution, and post-mortem generation in a unified timeline. APM collects traces and metrics via native OpenTelemetry integration — no proprietary agents required — while log management provides full-text search and alerting. An AI agent continuously monitors telemetry data, identifies root causes, and opens GitHub pull requests with proposed fixes for review. Deploy via Docker Compose or Kubernetes Helm charts with a Terraform provider for infrastructure-as-code configuration.

ODS turns a GPU machine or server you already own into a complete private AI stack with a single install command, replacing a shelf of separate tools with one system that serves models, chat, agents, automation, and search from your own hardware. The installer reads your GPU, VRAM, memory, and disk, then downloads a GGUF model matched to that hardware tier, and a compact bootstrap model starts answering within minutes while the full model finishes downloading. From the web dashboard you watch every service's health, ports, and resource use, restart what misbehaves, and check storage and updates without touching a terminal. You chat with local models in Open WebUI, hand background work to the Hermes and Portal agents, and build automations in n8n that connect the stack to more than 400 other apps. Documents you add become searchable knowledge through Qdrant vector storage, so answers cite your files instead of the model's memory. SearXNG and Perplexica answer web questions without trackers or accounts, Whisper transcribes speech, Kokoro reads text aloud, and ComfyUI generates images, all on the same box. Every bundled service is an extension you can enable, disable, or replace, and a Privacy Shield scrubs personal data before anything reaches an optional cloud model through the LiteLLM gateway. 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.

With over 7,000 GitHub stars and active community maintenance through version 0.26.0 released in June 2026, Homebox fills the gap between inadequate spreadsheets and overcomplicated enterprise asset management by providing a purpose-built inventory system designed specifically for home users, families, and small groups. The Go backend with SQLite storage deploys as a single Docker container consuming under 50MB of RAM at idle, running on hardware as modest as a Raspberry Pi while the responsive web interface adapts seamlessly across desktops, tablets, and smartphones. The entity-based architecture introduced in v0.26 unifies items and locations into a shared structure supporting custom fields, attachments, entity types, and reusable templates for consistent data entry across inventory categories. QR code generation creates printable labels that scan with any smartphone camera to instantly display item details, photos, serial numbers, and associated documents. Warranty tracking records purchase dates, prices, and expiration dates while maintenance scheduling sends reminders for recurring service tasks. Location hierarchies organize items spatially with nested sub-locations, and flexible label tagging enables cross-cutting categorization beyond physical placement. Multi-user support shares collections with family members or roommates with OIDC single sign-on integration for Active Directory, Okta, and other identity providers. CSV import and export handles bulk operations, while the full REST API enables automation and third-party integrations. Collection-level ZIP export packages complete inventories with attachments for backup or migration.

With over 7,500 GitHub stars and 140 contributors, Matterbridge is the Go-powered chat bridge that connects over 20 messaging platforms through a single TOML configuration file, letting teams communicate across platform boundaries without forcing anyone to switch applications. The gateway architecture routes messages bidirectionally between any combination of Discord, Slack, Telegram, Matrix, IRC, Mattermost, Microsoft Teams, XMPP, Rocket.Chat, Nextcloud Talk, Keybase, Mumble, Twitch, WhatsApp, VK, Gitter, Zulip, ssh-chat, and Harmony, with transparent username and avatar spoofing so bridged messages appear native on each platform. Message edits and deletes propagate across bridges, file attachments and inline images transfer between protocols, threading and reply context is preserved where platforms support it, and private group bridging enables confidential cross-platform conversations. Multiple independent gateways can run simultaneously, each bridging different channel sets with different protocol combinations. The REST API enables third-party integrations and custom bridges without modifying the Matterbridge codebase, while the tengo scripting engine allows inline message transformation and filtering. Game chat support bridges Minecraft and Counter-Strike server chat into messaging platforms. Deployment runs as a single static Go binary with zero dependencies, or as the official Docker image with the configuration file mounted as a volume.

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.

The Kubernetes project's own answer to cluster management UIs: maintained under SIG UI governance, Headlamp's roadmap tracks Kubernetes releases and its design philosophy reflects community needs rather than a vendor's product strategy. The React interface provides full read-write capabilities adapted to each user's RBAC permissions — delete, scale, edit, and restart buttons appear only when the authenticated user holds the corresponding cluster role, preventing accidental unauthorized actions. Multi-cluster support surfaces workloads across development, staging, and production from a single view without context switching. The plugin architecture drives extensibility through a curated catalog: an AI Assistant plugin answers natural-language cluster queries and performs operations via configurable LLM keys, Flux handles GitOps, Karpenter manages nodes. Integrated terminals provide browser-based exec access to running pods, live log streaming follows container output with filtering, and the YAML editor displays inline Kubernetes API documentation alongside resource definitions. Deployment creation forms let you configure containers, environment variables, volumes, and replicas without writing manifests. Side-by-side cluster comparison views surface differences in workload distribution. Works with any distribution: EKS, GKE, AKS, Minikube, Docker Desktop. Helm chart installation via the Headlamp repository with images on GitHub Container Registry.

evcc turns surplus rooftop solar and the cheapest hours of a dynamic tariff into cheap, clean kilometers by coordinating an EV charger, heat pump, and home battery from one local dashboard. Each charging point offers Off, Smart, and Fast modes. In Smart mode, charging starts once the surplus covers the car's minimum power, follows the sun up and down, pauses when clouds win, and can switch between one and three phases on wallboxes that allow it. A solar share slider lets small systems start earlier, and Always charge keeps fussy cars from being interrupted. Set a departure time and a target charge, and a charging plan picks the cheapest or cleanest hours before it, repeating weekly if you like. Tibber, Awattar, fixed and time-based rates, dynamic feed-in prices, and CO2 and solar forecasts all feed those decisions. A home battery can claim the surplus first or lend a boost for fast charging, and load management keeps several chargers inside a circuit's current limit while honoring grid operator dimming. Hundreds of wallboxes, inverters, meters, heat pumps, and vehicle APIs are supported, including Tesla, BMW, Mercedes-Benz, Skoda, and Volkswagen. Sessions land in a history with charts and CSV export, and REST, MQTT, InfluxDB, Grafana, Home Assistant, and openHAB link evcc to the rest of the house.

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.

Instead of deploying proprietary background agents across dozens of target nodes, engineers rely on Apache HertzBeat to monitor real-time infrastructure health, metrics gathering, threshold alerting, and public status pages from a central operations platform. Operations teams can poll hundreds of target services without deploying proprietary background daemons, gathering performance data across Linux hosts, Kubernetes clusters, SQL databases, and network switches using native connection protocols. Engineers can define custom monitoring targets directly within the web dashboard by composing declarative YAML templates that specify polling intervals, parsing expressions, and metric extraction rules. The centralized alert engine processes inbound threshold events, suppresses cascading alert storms during maintenance windows, and dispatches actionable incident notifications to Discord channels, Slack rooms, Telegram groups, and webhook endpoints. Telemetry streams flow into interactive charts with customizable refresh cadences, enabling site reliability engineers to inspect latency waterfalls, correlate log spikes against CPU exhaustion, and track disk capacity trends over extended timeframes. Administrators can also publish real-time public status pages that inform external stakeholders about service availability, scheduled downtime, and ongoing incident resolutions.

GoCD treats delivery as a pipeline you can see: every commit enters a sequence of stages, passes or fails in the open, and travels from first build to production deployment along one visible, traceable path. Stages split work into jobs that run in parallel on a fleet of agents, so unit tests, integration suites, packaging, and security scans finish together instead of queueing behind each other. Pipelines connect with fan-in and fan-out dependencies, meaning a release pipeline waits for every upstream component to pass before it assembles them, and one library build can feed a dozen services. The value stream map draws that whole web on one screen, from the triggering commit through every stage to deployment, and any run can be compared with another to spot exactly what changed. Materials watch Git, Subversion, or Mercurial repositories and start pipelines on new commits, while artifacts produced by one stage are fetched, versioned, and promoted by the stages after it. Environments group pipelines and agents so test and production stay isolated, resources tag agents by capability, and elastic agents appear on Docker, Kubernetes, or cloud hosts only while work exists. Pipeline definitions can live in YAML or JSON inside a repository, changing through code review like the software they deliver, and templates keep repeated release patterns consistent across teams.

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.

AiSOC delivers an open-source AI Security Operations Center that unifies event ingestion, graph correlation, autonomous triage, and purple-team adversary emulation into a single self-hosted console. Security analysts triage alerts across an interactive Investigation Rail that visualizes six-event attack timelines, pivot-path entity graphs, and recommended containment steps. The underlying LangGraph agentic engine reasons over ingested telemetry, querying MITRE ATT&CK frameworks, CISA Known Exploited Vulnerabilities catalogs, and Shodan intelligence while recording every prompt, tool execution, and evidentiary citation in an immutable Investigation Ledger. Incident responders execute automated containment playbooks, including host network isolation, credential revocation in identity providers, and firewall blocklist updates with human-in-the-loop sign-offs. Threat hunters input plain-English hypotheses into the natural-language hunt workbench to generate and execute ES|QL, SPL, and KQL queries against historical telemetry stores. Platform operators connect over seventy vendor connectors spanning CrowdStrike, SentinelOne, Microsoft Defender, AWS Security Hub, Okta, and Cloudflare to normalize streaming events into Open Cybersecurity Schema Framework standards.

A status page and uptime monitor in one Go binary: Statping-ng - the actively maintained fork of Statping - replaces the UptimeRobot-plus-Statuspage combo with a ~20 MB Docker image using under 50 MB of RAM. It checks services over HTTP, TCP, UDP, ICMP ping, and gRPC health checks on configurable intervals, with per-service timeouts, expected status codes, POST requests with custom JSON bodies, SSL verification, and failure thresholds before alerting. The public status page is the differentiator against plain monitors: visitors see live status, uptime percentages, and latency charts grouped into service categories, with incident announcements and scheduled-maintenance messages you publish from the dashboard - and Sass-based custom styling matches the page to your brand rather than a vendor template. When something fails, notifiers fire immediately: Slack, Discord, Telegram, SMTP email, PagerDuty, Twilio SMS, Pushover, and custom webhooks, each testable before saving. Because notifiers are single Go files, the plugin system makes new channels straightforward. A RESTful API manages services and reads uptime data programmatically, and the free Statping mobile app connects to your server via QR code for on-the-go monitoring. Data persists to SQLite, MySQL, or PostgreSQL. Point it at internal services too - anything the container can reach is monitorable.

The leading open-source tool for extracting business leads from Google Maps at production scale. The Go-based engine processes approximately 120 places per minute with optimized concurrency, extracting 33+ data points per listing including business name, address, phone number, website URL, rating, review count, latitude and longitude, opening hours, price level, and optionally crawling business websites for email addresses. Three interfaces serve different workflows: the CLI accepts query files for cron jobs and CI/CD pipelines with output to CSV, JSON, PostgreSQL, S3, or LeadsDB; the Web UI provides a browser-based dashboard with real-time job monitoring, a map view of scraped places, and interactive query submission; and the REST API at /api/v1 enables programmatic integration with full Swagger documentation at /api/docs. Built-in proxy rotation supports SOCKS5, HTTP, and HTTPS with authentication for large-scale runs, while the architecture scales from a laptop to Kubernetes clusters with queue-based worker distribution. The SaaS edition adds multi-user access with API key management, admin UI with 2FA, job queue orchestration, and one-command cloud deployment via an interactive wizard. An AI Agent Skill enables coding agents to run scrapes programmatically. Deploy via Docker or build from source requiring Go 1.26.5+.
