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 是一个自动化字幕管理系统和下载器，旨在发现、获取和同步电影和电视节目的字幕。它作为一个媒体库伴侣，通过 API 与外部媒体管理器和服务器集成，以跟踪缺失的字幕并确保库保持最新。 该项目通过高级媒体处理脱颖而出，使用神经网络音频转录从音轨生成字幕或将外语对话翻译成英语。它还具有基于音频的同步功能，可将字幕时间与视频内容对齐，并能在发现更高质量版本时自动升级现有字幕。 该系统涵盖了广泛的自动化功能，包括语言配置文件管理、跨多个字幕提供商的自适应搜索调度以及事件驱动的 Webhook 触发器。它支持通过 SQLite 或 PostgreSQL 进行数据持久化，并包括用于定位跨不同主机系统或容器的媒体文件的路径映射翻译工具。 该应用可以作为 Windows 上的后台服务或通过其他平台上的系统初始化管理器部署，并支持用于远程访问的反向代理配置。
