GreptimeDB is a distributed, open-source time-series database built for unified observability. It stores and queries metrics, logs, and traces together in a single columnar engine, supporting both SQL and PromQL for analysis. The database is designed as a Kubernetes-native operator with a decoupled compute and storage architecture, enabling horizontal scaling and multi-region deployment. What distinguishes GreptimeDB is its role as a multi-protocol ingestion gateway, accepting data through OpenTelemetry, Prometheus Remote Write, InfluxDB, Loki, Elasticsearch, Kafka, and MQTT protocols without

Lamp Cloud is a multi-tenant SaaS backend framework built on Java and Spring Cloud that provides a complete foundation for building enterprise-grade administration systems. Its core identity centers on supporting multiple tenant isolation strategies—including database-per-tenant, schema-per-tenant, and shared-table modes—that can be switched without altering business code, alongside a role-based access control system enforced at the gateway layer across all microservices. The framework distinguishes itself through comprehensive tenant lifecycle management tools that allow creating, configurin

Weblate is an open-source web-based translation management system that provides a collaborative platform for teams to review, suggest, and approve translations in real time. It functions as a continuous localization platform, automatically synchronizing translations with source code changes in version control repositories, and can be deployed either as a self-hosted server or through a managed cloud hosting service. The system integrates directly with Git hosting platforms like GitHub, GitLab, and Bitbucket, storing all translations in version control with individual translator attribution re

Tortoise ORM is an asynchronous object-relational mapper for Python that mirrors Django's model and queryset API while running on asyncio. It defines database tables as Python classes with typed fields and supports foreign key, many-to-many, and one-to-one relations, providing a chainable query API for filtering, annotating, grouping, and prefetching related objects without blocking the event loop. The ORM includes a built-in migration engine that detects model changes, generates migration files, and applies or reverts schema changes through a command-line tool. It connects to PostgreSQL, MyS

wger is an open-source web application for fitness tracking, workout planning, and nutrition management. It provides a self-hosted platform where users can design weekly workout routines from a built-in exercise library, log their training progress, and plan daily meals using a food database with automatic nutritional calculations. The application supports multi-user accounts with credential-based login, passkey authentication, and third-party sign-in through OAuth providers. The platform includes a documented REST API that enables programmatic access to workout logs, meal plans, and user dat

CKAN is an open-source data management platform that provides the foundation for building data portals. It supports the full lifecycle of datasets—from creation and organization to publishing, cataloging with faceted search, and interactive data visualization—all through a web interface. The platform is built on a modular architecture that includes a plugin-based extensibility system, a harvesting framework for importing metadata from external sources, and a standardized RESTful JSON API for programmatic access to datasets and metadata. The web interface is rendered using the Jinja2 templatin

Django Silk is a profiling and inspection toolset for Django applications designed to capture SQL queries, HTTP request data, and execution timing for diagnostics. It functions as a performance profiler and debugging middleware that records runtime execution data to provide a comprehensive overview of application behavior. The system includes a database profiler for identifying slow operations through detailed timing data and an HTTP request inspector for reviewing headers, bodies, and network traffic via a web interface. It allows for the reproduction of specific server requests through gene

Athens is a Go module proxy server and dependency cache that provides a persistent storage system for Go dependencies. It acts as a mirror and datastore to ensure reproducible build environments by storing immutable copies of external packages, protecting against upstream deletions or outages. The project distinguishes itself by serving as a secure gateway for private Go module hosting, utilizing authentication tokens, SSH keys, and GitHub Apps to retrieve dependencies from private version control systems. It further enables software dependency compliance through request filtering and checksu

Bazarr ist ein automatisiertes Untertitel-Management-System und Downloader, der darauf ausgelegt ist, Untertitel für Filme und TV-Serien zu finden, zu beziehen und zu synchronisieren. Es fungiert als Begleiter für Medienbibliotheken, der sich über APIs in externe Medienmanager und Server integriert, um fehlende Untertitel aufzuspüren und Bibliotheken auf dem neuesten Stand zu halten. Das Projekt zeichnet sich durch fortschrittliche Medienverarbeitung aus und nutzt neuronale Audio-Transkription, um Untertitel aus Audiospuren zu generieren oder fremdsprachige Dialoge zu übersetzen. Es bietet zudem audiobasierte Synchronisation, um das Timing der Untertitel an den Videoinhalt anzupassen, und kann bestehende Untertitel automatisch aktualisieren, wenn qualitativ hochwertigere Versionen gefunden werden. Das System deckt ein breites Spektrum an Automatisierungsfunktionen ab, einschließlich Sprachprofil-Management, adaptivem Such-Scheduling über mehrere Untertitel-Anbieter hinweg und ereignisgesteuerten Webhook-Triggern. Es unterstützt Datenpersistenz via SQLite oder PostgreSQL und enthält Tools für Path-Mapping-Übersetzungen, um Mediendateien über verschiedene Host-Systeme oder Container hinweg zu lokalisieren. Die Anwendung kann als Hintergrunddienst unter Windows oder über System-Init-Manager auf anderen Plattformen bereitgestellt werden, mit Unterstützung für Reverse-Proxy-Konfigurationen für den Fernzugriff.
