Open Source Development & DevOps Software
CouchBase
Couchbase, originally known as Membase is an award-winning, open-source, distributed multi-model NoSQL and document-oriented cloud database. It is designed and optimized for interactive applications and may serve many concurrent users by creating, storing, retrieving, aggregating, manipulating and presenting data. Couchbase delivers unmatched versatility, performance, scalability, and financial value across cloud, on-premises, hybrid, distributed cloud, and edge computing deployments.
PouchDB
PouchDB is a free and open-source JavaScript database inspired by Apache CouchDB. The database is designed from the ground-up to run well within modern web browsers. With PouchDB you can create web applications that works as well offline as they do online. PouchDB achives this by storing data locally, then synchronize it with CouchDB and compatible servers when the user get internet access once again. This is especially useful for applications facing countries and regions with lower quality internet connections or unstable infrastructure.
TiDB
A Chinese developed open-source NewSQL database that supports analytical processing and hybrid transactional workloads. TiDB is licensed under the Apache 2.0 license and primarily developed by PingCAP, Inc. The database provides high availability with strong consistency and horizontal scaling and is compatible with MySQL.
SQLite
SQLite is a free and open-source relational database management system that implements a small, fast, self-contained, high-reliability, full-featured, SQL database engine. Rather than being a typical client–server database engine, SQLite is self-contained and can be embedded into applications. Making it perfect for development frameworks that want to provide a default database without setup, or applications that needs an embedded database. SQLite is built into all mobile operating systems and most computers and comes bundled with a countless applications. SQLite is also ACID-compliant and implements most of the SQL standard, generally following PostgreSQL syntax.
Zabbix
Zabbix provides an enterprise-class monitoring solution for network monitoring and application monitoring. The software can handle over millions of metrics and can be used for individual components or networks, servers, virtual machines and cloud services. Where data like network utilization, CPU load and disk space consumption can individually be monitored. Zabbix is developed openly and is fully open-soruce.
TimescaleDB
TimescaleDB is a leading open-source relational database for time-series data. The database is provided as fully managed or self‑hosted software, giving the power of choice back to developers and organizations. Timescale gives you all the reliability and flexibility of PostgreSQL. It allows you to use regular SQL to construct queries to better understand your products and your users. While achieve 10-100x faster queries than PostgreSQL, InfluxDB, and MongoDB with native optimizations for time-series.
CouchDB
CouchDB is a free and open-source document-oriented NoSQL database developed by the Apache Foundation. The database is written and implemented in the language Erlang and provides the use of multiple formats and protocols to store, transfer, and process data. With CouchDB you query data with JavaScript using MapReduce, and HTTP for an API. Which can be done across multiple distributed CouchDB instances as the database has the ability to synchronize multiple copies of the same database, across servers.
WatermelonDB
WatermelonDB is a free and open-source database optimized for building complex applications in React and React Native. The goal of WatermelonDB is to provide real-world performance for apps that can scale from hundreds to tens of thousands of records and while remaining performant. Loading a full database into JavaScript can be expensive, WatermelonDB fixes this by being lazy as a default, and only loads data upon request.
KeyDB
KeyDB is fast, free, and open-source NoSQL database with full compatibility for Redis APIs, clients, and modules. The database was originally forked from the Redis code-base and has been improved to handle multithreading, memory efficiency, and higher throughput. KeyDB is now a fully multithreaded and allow many machine cores to operate a single node resulting in 5X the throughput of Redis (v5) and up to 3x the throughput of Redis (v6). KeyDB also includes Redis Enterprise such as Active Replication, FLASH storage support, and other features like direct backup to AWS S3.
aaPanel
aaPanel is a free and open source web hosting control panel. It's a simple, yet powerful control panel that provides one click installs for LNMP and LAMP development stacks through an intuetive graphical user interface (GUI). aaPanel was designed to help you save time when deploying web sites and applications to the web. Allowing you to focus on building your project, rather than focusing on installation and configuration of servers and tooling. Over 3 million people use aaPanel to create quickly deployable web environments for Apache HTTP Server, Nginx and OpenLiteSpeed.
