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 es un servidor proxy de módulos de Go y caché de dependencias que proporciona un sistema de almacenamiento persistente para dependencias de Go. Actúa como un espejo y almacén de datos para garantizar entornos de construcción reproducibles almacenando copias inmutables de paquetes externos, protegiendo contra eliminaciones o interrupciones en el origen. El proyecto destaca por servir como una puerta de enlace segura para el alojamiento de módulos de Go privados, utilizando tokens de autenticación, claves SSH y GitHub Apps para recuperar dependencias de sistemas de control de versiones privados. Además, permite el cumplimiento de las dependencias de software mediante el filtrado de solicitudes y el proxy de sumas de comprobación, lo que evita que los metadatos de los módulos privados se filtren a servidores públicos. El servidor admite una amplia gama de backends de almacenamiento, incluyendo disco local, bases de datos NoSQL y almacenes de objetos en la nube compatibles con S3. Incluye capacidades para el almacenamiento en caché de dependencias distribuido con bloqueo compartido para evitar descargas redundantes a través de múltiples instancias y proporciona herramientas para el prellenado de almacenamiento en entornos aislados (air-gapped). El servidor puede desplegarse a través de contenedores Docker, gráficos Helm de Kubernetes o varias plataformas en la nube gestionadas.

Bazarr is an automated subtitle management system and downloader designed to discover, acquire, and synchronize subtitles for movies and TV shows. It functions as a media library companion that integrates with external media managers and servers via APIs to track missing subtitles and ensure libraries are up to date. The project distinguishes itself through advanced media processing, using neural-network audio transcription to generate subtitles from audio tracks or translate foreign dialogue into English. It also features audio-based synchronization to align subtitle timing with video conten
