OutSystems' official Avalonia/WPF control wrapping CefGlue — embeds Chromium in .NET desktop apps with strongly-typed JS evaluation, custom resource handlers, and cross-platform (Win/macOS/Linux) support.

OutSystems-maintained full .NET binding for the Chromium Embedded Framework (CEF), including the Python-based code generator that auto-derives the C# P/Invoke interop layer straight from CEF's C++ headers.

A Go CLI + MCP server that lets AI coding agents (Claude Code, Copilot, Cursor, etc.) read and safely mutate binary Mendix .mpr project files through a purpose-built SQL-like textual DSL called MDL, plus a metadata catalog, a Starlark-scriptable linter, a REPL, and a VS Code extension - all Mendix's answer to exactly the OML-tooling-for-AI-agents problem an OutSystems ecosystem builder would want solved.

The actual, current (v2.30.0) source of the OutSystems UI framework - 70+ UI patterns (Carousel, Dropdown, DatePicker, Tabs, Sidebar, RangeSlider, Wizard, BottomSheet, etc.) and screen-template SCSS shipped in every O11/ODC Forge 'OutSystems UI' component, for both Reactive Web and Native Mobile.

Official OutSystems Python package (PyPI: outsystems-pipeline) wrapping the LifeTime REST API end-to-end: fetch app/environment data, generate deployment manifests, start/continue/monitor deployments, tag apps, run CI-driven BDD/regression tests, and even air-gapped deployment via OSPTool -- with ready-made Jenkins and Azure DevOps pipeline templates.

OutSystems framework for building React.js UIs hosted inside Avalonia/WPF .NET desktop apps, with a companion 'ViewGenerator' tool that auto-generates strongly-typed C# proxy classes straight from TypeScript component declarations.

Mature, PowerShell-Gallery-published PowerShell module for fully scripting an on-prem OutSystems 11 Platform Server installation end-to-end: prereqs, IIS/firewall/perf tuning, Service Studio/Integration Studio install, and programmatic module/solution publishing via Service Center's legacy SOAP/REST APIs.

Official, actively-maintained (releases as recent as this week) Go CLI (`outsystemscc`) that runs on a customer's private network and opens a secure reverse tunnel to an ODC Private Gateway, letting ODC apps reach on-prem/private services (internal REST APIs, SMTP, DBs, SMB) with zero inbound firewall rules.

Official distribution repo for the OutSystems remote MCP server integration (Claude Code plugin, Claude Desktop config, Kiro Power) -- ships the actual SKILL.md/POWER.md agent-facing instruction docs that define tool conventions, auth flow, mentor session protocol, and error taxonomy for driving OutSystems from any MCP-capable AI assistant.

Official OutSystems Professional Services accelerator: Elasticsearch ILM policies/index templates/transforms + Logstash pipelines + Kibana dashboards, purpose-built to ingest and visualize OutSystems platform monitoring data (logs, request events, perf counters).

The official, current Markdown source repository for the OutSystems Developer Cloud (ODC) documentation (900+ docs pages, full error-code catalog, images) -- the canonical source-of-truth behind success.outsystems.com/documentation/outsystems_developer_cloud.

Official, actively-maintained OutSystems Data Grid (Reactive Web) source: TypeScript OSFramework/Providers abstraction over Wijmo FlexGrid plus a .NET Integration Studio extension for entity-to-JSON metadata conversion.

The actual '@capacitor/inappbrowser' plugin (npm package, author field literally 'Outsystems') used by OutSystems Mobile Apps built on Capacitor: three ways to open a URL (embedded WebView, native system browser via Custom Tabs/SFSafariViewController, or the device's external browser), backed by OutSystems' own native libraries.

OutSystems Support's own open-source Windows diagnostic tool (WinForms + CLI) that collects IIS config, Windows Event Log entries, perf counters, live .NET thread dumps, and Platform-DB integrity checks (SQL Server/Oracle) into a single support bundle.

Official, actively-maintained source of the OutSystems Maps Forge/OutSystems-native component: a TypeScript library compiled to a single AMD module that exposes a unified map API to Reactive Web apps, abstracting Google Maps and Leaflet/OpenStreetMap behind a shared OSFramework provider layer.

OutSystems' actively-maintained fork of Apache cordova-plugin-camera (v4.2.0-OS63) with a proprietary compiled Swift native library (OSCameraLib.xcframework), a modern Kotlin/AndroidX CameraLauncher, and a Capacitor post-update hook that patches the host app's root build.gradle to add OutSystems' private Azure Artifacts Maven feed.

A complete, real-world implementation of a custom OutSystems Platform Database Connector for PostgreSQL (plus a bonus Amazon Redshift variant), built against the official (Limited-Availability, approval-gated) 'Database Connector SDK' for BOTH the .NET/HubEdition on-prem platform and the J2EE/Wildfly/JBoss edition.

A real Roslyn DiagnosticAnalyzer + CodeFixProvider, packaged both as a VS/VSCode/Rider-installable analyzer (NuGet dev-dependency, auto-referenced via OutSystems.ExternalLibraries.SDK) and a VSIX for Visual Studio, that gives live IDE feedback + one-click quick-fixes for ODC External Libraries SDK rule violations (OS-ELG-MODL-*) as you type C# code -- before you ever upload the assembly to the ODC Portal.

A dockerized LLM agent pipeline (LangChain/LangGraph-style, OpenAI/Anthropic models) that takes a natural-language description of desired functionality and generates a fully validated ODC External Library C# project + unit tests, using the sibling CustomCode-Analyzer as a build-time gate and a reflection loop to self-correct on build or test failure.

OutSystems' officially-supported fork of katzer/cordova-plugin-local-notifications, whose 'outsystems' branch (153 commits ahead / 302 behind upstream) reveals the actual internal CI/CD pipeline OutSystems uses to certify Cordova plugins for MABS.

Official ODC External Libraries SDK template collection: basic/advanced IBAN-checker C# library, a SOAP-consumption template (WCF proxy over BasicHttpBinding), and a full mTLS client-certificate template using NSwag-generated clients -- all wired with [OSInterface]/[OSAction]/[OSParameter].

Cross-platform .NET 6 CLI (dotnet, ~600 lines core) that reads/edits OML files directly by loading OutSystems' own private assemblies (OutSystems.Common / OutSystems.RuntimeCommon / OutSystems.Model.Implementation) via reflection, for platform versions O9.1, O10 and O11.

A tight, correct ODC External Library sample that wraps Microsoft Kernel Memory (RAG/vector search) with OpenAI embeddings + Qdrant as three OSAction methods -- IndexWebpage, Search, DeleteDocument -- for OutSystems AI Agent Builder tool use.

A complete, production-quality OutSystems ODC External Logic library (ZXingLib) that wraps ZXing.Net to encode/decode 15+ barcode and QR formats, with smart-QR helpers for WiFi, vCard/MeCard contacts, calendar events, geo, phone/SMS/FaceTime links, plus a full NUnit test suite and a ready-to-use publish script.

MCP server (stdio for Raycast/Claude Desktop + Cloudflare Worker for Claude.ai/ChatGPT) that drives OutSystems ODC's AI app-generation API end-to-end: prompt in, live deployed app URL out.

OutSystems' fork of chemerisuk/cordova-plugin-firebase-analytics (224 commits ahead of upstream on the 'outsystems' branch!) is effectively a ground-up rewrite of the native bridge in Kotlin/Swift with typed GA4 event validation and full Google Consent Mode v2 support.

Current, production-quality ODC External Logic library (.NET 8) that renders arbitrary web pages to PDF/PNG via a pooled headless-Chromium (PuppeteerSharp) instance, composites headers/footers/pagination with PDFsharp, and offers S3/REST offload paths for outputs that exceed ODC's 5.5MB payload cap -- ships with unit, in-process integration, and live-tenant E2E test suites plus an evidence-cited ARCHITECTURE.md.

A well-engineered MCP server that exposes the full OutSystems LifeTime REST API v2 as 66 conversational tools across 10 domains (environments, applications, deployments, users, teams, roles, modules, DB connections, configurations, operations), runnable via Docker (stdio) or Streamable HTTP (remote/Claude.ai).

Enterprise-grade cross-platform (web/mobile/Mac/Windows) test automation framework combining Playwright/WebdriverIO+Appium with Claude/OpenAI-driven self-healing locators, AI test-planning/generation/healing agents, a Playwright-MCP client/server, and a live React ops dashboard.

Official, actively-maintained (semantic-released, 2026 commits) ionic-team/OutSystems Cordova Filesystem plugin whose 'outsystems-wrapper' package shows the exact JS shim OutSystems uses to run one API across Cordova (MABS), Capacitor, and web preview.
