Postiz is an open-source social media management platform designed to centralize the scheduling, publishing, and analysis of content across diverse social networks, community forums, and blogging platforms. It functions as a unified hub where users can coordinate, review, and distribute content through a shared team workspace, while leveraging integrated artificial intelligence to assist in drafting text and generating multimedia assets. The platform distinguishes itself through a modular architecture that utilizes a provider-specific adapter pattern to ensure consistent content distribution

Discord.js is a Node.js library and framework for interacting with the Discord API. It provides a comprehensive set of wrappers for REST and WebSocket connections, enabling the development of automated server accounts and real-time chat applications. The project distinguishes itself through a distributed bot sharding system that splits a single bot instance across multiple processes to handle high server counts and large-scale workloads. It also includes a specialized voice API wrapper for managing audio streams and voice channel connectivity. The library covers broad capability areas includ

Yaak is a cross-platform desktop client and command-line utility designed for developing, testing, and debugging API endpoints. It supports multi-protocol request execution for REST, GraphQL, and gRPC services, providing a unified environment for managing network interactions, authentication credentials, and automated testing workflows. The tool distinguishes itself through a local-first architecture that stores all workspace configurations and request definitions directly on the filesystem. This design enables native integration with version control systems like Git, allowing teams to track

Webhook.site is a web-based tool that captures, inspects, and debugs incoming HTTP requests and emails sent to a unique URL, without requiring any server setup. It also functions as an API mocking and response modification tool, capable of generating mock APIs from OpenAPI specifications and altering HTTP responses, headers, and status codes for testing purposes. Beyond inspection, it serves as a platform for webhook automation and workflow orchestration, triggering multi-step automations—including database queries, SSH commands, and HTTP calls—when a webhook is received. The service distingu

Jo ist ein Kommandozeilen-Utility, das dazu entwickelt wurde, JSON-Objekte und -Arrays direkt aus Shell-Argumenten und Standard-Input zu konstruieren und zu manipulieren. Es fungiert als Datenverarbeitungstool, das Roh-Input in strukturierte Formate transformiert und so die Generierung komplexer Payloads für APIs, Konfigurationsdateien und automatisierte Daten-Pipelines ermöglicht. Das Tool zeichnet sich durch seine Fähigkeit aus, hierarchische Datenstrukturen unter Verwendung pfadbasierter Definitionen aufzulösen, sowie durch seine integrierte Typ-Inferenz-Engine, die Input-Werte automatisch in native Boolean-, Numeric- oder Null-Typen umwandelt. Benutzer können durch explizite Datentyp-Erzwingung, Inhaltsfilterung und die Möglichkeit, externe Dateiinhalte direkt in die generierte Struktur einzubetten, eine präzise Kontrolle über die Ausgabe ausüben. Das Utility unterstützt eine breite Palette von Datenkonstruktionsaufgaben, einschließlich des Zusammenführens neuer Informationen in bestehende Strukturen und des Umschaltens zwischen kompakter und pretty-printed Ausgabe. Es integriert sich in shell-basierte Workflows durch die Bereitstellung standardisierter Exit-Codes, um den Erfolg oder Misserfolg von Datentransformationsoperationen zu signalisieren.

afrog is an HTTP vulnerability scanner and web vulnerability management system that identifies security flaws and known CVEs using a YAML-based rule engine. It functions as a payload generator and scanner, comparing server responses against detection rules to find unauthorized access points. The project provides a framework for out-of-band security testing, detecting blind vulnerabilities by triggering and verifying external DNS or HTTP callbacks. Beyond web traffic, it includes a protocol fuzzer capable of executing multi-step read and write sequences over raw TCP and SSL sockets to identify

This is a desktop HTTP client application used for constructing, sending, and analyzing HTTP and GraphQL requests. It provides a graphical interface for API development and testing, including a dedicated GraphQL client with schema-driven autocomplete and validation. The project features an integrated AI assistant that generates API requests from natural language prompts. It supports a complex organization system of spaces and collections with hierarchical authentication inheritance and recursive variable resolution for dynamic request values. The tool covers a broad range of capabilities, in
