MongoDB is a source-available, cross-platform, document-oriented database program. Classified as a NoSQL database product, MongoDB uses JSON-like documents (called BSON) with optional schemas. Released in February 2009 by 10gen (now MongoDB Inc.), it supports features like sharding, replication, and ACID transactions (from version 4.0). MongoDB Atlas, its managed cloud service, operates on AWS, Google Cloud Platform, and Microsoft Azure. Current versions are licensed under the Server Side Public License (SSPL). MongoDB is a member of the MACH Alliance.

Redis (; Remote Dictionary Server) is an in-memory key–value database, used as a distributed cache and message broker, with optional durability. Because it holds all data in memory and because of its design, Redis offers low-latency reads and writes, making it particularly suitable for use cases that require a cache.

Elasticsearch is a source-available search engine developed by Elastic. It is based on Apache Lucene and provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Official clients are available in Java, C#, PHP, Python, Ruby, and other languages. According to the DB-Engines ranking, Elasticsearch is the most popular enterprise search engine.

Kibana is a source-available data visualization dashboard for Elasticsearch, developed by Elastic NV. It is written in TypeScript and JavaScript and runs as a browser-based application backed by a Node.js server. Kibana lets users create bar, line, and scatter charts, pie charts, maps, and other visualizations against data stored in an Elasticsearch cluster, and arrange those visualizations into shared dashboards.
