GrandNode lets you run one shop, a dozen regional storefronts, or a full marketplace from a single installation, with a back office for every role involved. Each store gets its own domain, theme, currencies, languages, and settings, and a store manager panel limits staff to the catalog, orders, and customers of their own store. Outside sellers join through a vendor panel where they manage their own products and orders. The catalog handles attributes and combinations, bundles, grouped items, downloads, date-based reservations, and auctions. B2B selling adds customer groups, tier prices, sales employees, and approvals. Checkout accepts payments through plugins such as Stripe Checkout, Braintree, and cash on delivery, with shipping by fixed rate, weight, or pickup point and tax rules by country, state, or zip code. Marketing tools include coupon codes, discount rules, loyalty points, gift vouchers, customer segments, newsletter campaigns, and push notifications.

Keep every VPS, home-lab box, NAS, and router you run on one self-hosted dashboard, with a small agent on each machine reporting whether it is up and how hard it is working. Nezha tracks CPU, memory, swap, disk, load, traffic, process counts, and TCP and UDP connections on Linux, Windows, macOS, OpenWRT, and Synology machines, plus GPU and temperature where supported. Servers sort into groups and appear as cards, a list, or a world map, with live charts and, when the optional time-series database is on, 1, 7, and 30 days of history. HTTP GET, ICMP Ping, and TCPing monitors run from the servers you choose, chart latency and packet loss, and warn about HTTPS certificate changes and upcoming expiry. Alert rules watch offline servers, resource use, bandwidth, and cycle traffic limits, then message Telegram, Slack, Matrix, Feishu, DingTalk, or any webhook. A browser terminal and file manager handle quick fixes, while scheduled or alert-triggered tasks run backups, restarts, and scripts across many servers. DDNS updates Cloudflare, Tencent Cloud, or Hurricane Electric records when an agent's IP changes, and NAT traversal publishes a home router or NAS page on your own domain. Admin and user roles, scoped API tokens, and an optional MCP endpoint let people and AI tools list servers and run commands within their permissions.

From the first rack to the last circuit, Nautobot is the open-source network source of truth that records what your network should look like and runs automation against it. Built-in models cover locations, racks, devices, interfaces, cables, VLANs, VRFs, IP prefixes, circuits, and contacts, so one searchable record replaces the spreadsheet and the wiki. Teams encode their own standards with custom fields, user-defined relationships, computed fields, and validation rules. Config contexts attach JSON or YAML data, such as syslog servers, to devices by location, role, platform, or tag. Jobs run your own automation code from the web UI, REST API, or command line, on a schedule, or through hooks when an object changes, with approvals and logs built in. Query the data over REST or GraphQL, and let the GraphiQL editor autocomplete a device and interface query you can save inside Nautobot. When an object is created, updated, or deleted, webhooks notify outside systems, with Jinja2-templated bodies and HMAC SHA-512 signatures. Git repositories can carry export templates, Jobs, and config contexts too, so YAML data and Jinja2 templates get pull request review before Nautobot syncs them. Open-source Apps add Golden Configuration for config backup, compliance, and remediation, Device Lifecycle for hardware tracking, SSoT for syncing other systems, and ChatOps. Object permissions and change logging keep a shared instance auditable. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.

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 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.

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.
